Every wildfire starts small. The problem is that by the time most are detected, minutes have already passed and, under increasingly common conditions driven by a warming climate, a fire can grow beyond any tanker truck’s capacity to contain. The gap between ignition and coordinated response currently averages around 40 minutes. Firefighters have long understood the math: a spoonful of water in the first second, a bucket in the first minute, a truckload in the first hour. The XPRIZE Wildfire competition is an $11 million global effort to prove that autonomous systems, including AI-enabled drones, ground-based sensor networks, and space-based detection platforms, can collapse that window to 10 minutes. Our guest is Andrea Santy, who leads the program. She came to XPRIZE after nearly two decades at the World Wildlife Fund, where she watched conservation projects fall to wildfire. That experience sharpened her understanding of the stakes: wildfires are now the leading driver of deforestation globally, having surpassed agriculture. In places like the Amazon, the Congo Basin, and parts of tropical East Asia, a single fire can eliminate species found nowhere else on Earth. In cities, it can destroy entire neighborhoods in hours. On January 7, 2025, Santa Ana winds drove flames through Pacific Palisades and Altadena, destroying more than 16,000 structures, killing 30 people, displacing 180,000 residents, and generating between $76 billion and $130 billion in total economic losses from a single event. Annual U.S. wildfire costs, when healthcare, lost productivity, ecosystem damage, and rebuilding are included, are estimated between $394 billion and $893 billion. XPRIZE announced the five autonomous wildfire response finalists just over a year after the LA fires: Anduril, deploying its Lattice AI platform with autonomous fire sentry towers and Ghost X drones; Dryad, running solar-powered mesh sensor networks that detect fires at the smoldering stage; Fire Swarm Solutions, coordinating heavy-lift drone swarms that can deliver 100 gallons of water autonomously; Data Blanket, building rapidly deployable drone swarms for real-time perimeter mapping and suppression; and Wildfire Quest, a team of high school students from Valley Christian High School in San Jose who used multi-sensor triangulation to locate fires that can’t be seen from monitoring positions, solving the literal over-the-hill problem that any fire detection system faces.

The conversation covers what the finalists demonstrated during semi-final trials at 40-mile-per-hour winds, why the decoy fire requirement — distinguishing a wildfire from a barbecue, a pile burn, or a flapping tarp — is one of the hardest AI classification problems in the competition, and how autonomous systems would integrate with existing incident command structures. Santy is direct about where progress is lagging: the testing is ahead of the regulations. Autonomous drones operating beyond visual line of sight and coordinating with manned aircraft in active fire emergencies require FAA frameworks that don’t yet exist at the necessary scale. There’s also the deeper ecological tension — the growing scientific consensus that many fire-adapted landscapes need more fire, not less, and that indigenous fire stewardship practices developed over millennia have a place alongside autonomous suppression technology. One XPRIZE finalist is already working with an indigenous community in Canada to pilot their heavy-lift drone system in a remote area where that community is exploring how the technology fits their land management approach. Meanwhile, the Trump administration’s FY 2026 budget proposes eliminating Forest Service state fire capacity grants, cutting vegetation and watershed management programs by 30%, and zeroing out $300 million in forest research funding — maintaining suppression spending while gutting the prevention and detection infrastructure that could reduce what there is to suppress. The engineering, Santy says, has arrived. Whether the institutions can move at the speed the crisis demands is the harder question.

Interview Transcript
Mitch Ratcliffe 0:09
Hello, good morning, good afternoon, or good evening, wherever you are on this beautiful planet of ours. Welcome to Sustainability In Your Ear. This is the podcast conversation about accelerating the transition to a sustainable, carbon-neutral society, and I’m your host, Mitch Ratcliffe. Thanks for joining the conversation today.
Fire season is coming, and we’re going to dig into how new technology may catch and contain fires in the first few minutes after ignition. There’s a saying among firefighters: you can fight fire in the first second with a spoonful of water, in the first minute with a bucket of water, and in the first hour with a truckload of water. The problem is that by the time most wildfires are detected, minutes have already passed, and in those minutes, under increasingly common conditions, a fire can grow beyond any tanker truck’s capacity.
On January 7, 2025, hurricane-force Santa Ana winds drove flames through Pacific Palisades and Altadena in Los Angeles, and in a matter of hours, more than 16,000 structures were destroyed. Thirty people were killed, and 180,000 residents were forced to flee. The total economic losses are estimated to be between $76 billion and $130 billion from a single fire event. And that was just one week in one city. In 2025, the U.S. recorded more than 61,500 wildfires that burned nearly 5 million acres, leading to annual U.S. wildfire costs of between $394 billion and $893 billion when you factor in the cost of healthcare, lost productivity, ecosystem damage, and the expensive task of rebuilding entire cities.
So there’s an identifiable gap in the current best practices, which take roughly 40 minutes from ignition to deliver a coordinated response. What if you could cut that to 10 minutes, when only a few buckets of water could extinguish a threat? And what if autonomous systems — AI-enabled drones and ground-based sensor networks — could detect a fire, distinguish it from a prescribed burn, and suppress it before getting a human on the radio?
That’s the challenge behind the XPRIZE Wildfire program, an $11 million global competition now entering its final year, and our guest today is Andrea Santy, the program director leading it. Andrea came to XPRIZE after nearly two decades at the World Wildlife Fund, and before that she spent time at the Smithsonian Institution, leading conservation and academic programs.
On January 29 — just after the one-year anniversary of those LA fires — XPRIZE announced the five finalist teams advancing in the autonomous wildfire response track of the competition. They include:
Andruil, a defense technology company deploying a Lattice AI platform with autonomous fire sentry towers and Ghost X drones that watch for fires at the moment they break out;
Dryad, a German company running solar-powered sensor networks that detect fires at the smoldering stage;
Fire Swarm Solutions, a Canadian team coordinating heavy-lift drone swarms that can carry 100 gallons of water autonomously to the point where a fire begins;
Data Blanket, building a rapidly deployable drone swarm system for real-time perimeter mapping and suppression; and
Wildfire Quest, a team of high school students from Valley Christian High School in San Jose who partnered with two aerospace companies to use multi-sensor triangulation to locate fires that cannot be seen from monitoring locations — because, after all, a lot of fires happen just over the hill.
A separate track of the competition, the space-based wildfire detection and intelligence program, includes 10 finalists from six countries who are heading to Australia in April for their own finals. Those teams will have one minute to detect all fires across an area larger than a state, and 10 minutes to deliver precise reports to firefighting decision-makers on the ground.
We’re going to talk with Andrea about what the finalists demonstrated during live trials, why the decoy fire requirement is one of the hardest AI classification problems in the competition, and how these autonomous systems would actually integrate with existing wildfire incident command structures. We’ll also dig into the tension between suppression technology and the growing scientific consensus that many landscapes need more fire, not less, and whether indigenous fire stewardship practices have a place in this conversation.
You can learn more about XPRIZE Wildfire at xprize.org/competitions/wildfire. Can autonomous drones and AI-driven sensor networks actually detect and suppress a wildfire in less than 10 minutes? Let’s find out right after this brief commercial break.
[COMMERCIAL BREAK]
Welcome to the show, Andrea. How are you doing today?
Andrea Santy 5:34
I’m doing great, Mitch. Thanks for having me.
Mitch Ratcliffe 5:34
Well, thanks for joining me. We’ve had XPRIZE leaders on the show a number of times, and you do such interesting work. You announced the finalists just at one year after the catastrophe in LA. How did that reshape the urgency and direction for the XPRIZE Wildfire competition?
Andrea Santy 5:34
It definitely focuses a more intense light on the competition and the need for these solutions. Climate change is driving more intense, more frequent wildfires all around the world, and so I think the urgency was already there. But when you have a disaster at the scale and scope of the LA fires, it absolutely changes the way that everybody thinks about wildfires.
Mitch Ratcliffe 6:04
What’s the realistic timeline for these technologies in the competition to potentially start changing the way that we fight fire and the outcomes of those fires?
Andrea Santy 6:14
So I’ll start by saying we were in LA when the fires started. XPRIZE has a lot of LA-based staff, and we’re originally LA-based, and we were having our staff meeting — so our entire staff was there. We knew from our prize that it was going to be very high risk, and so we were in touch with fire chiefs as the fires were starting. We were able to go out and see where the fires had gone through the Palisades and part of the city — basically 24 hours after it had happened.
It really, I will just say, definitely had a huge impact in terms of being able to see a landscape, communities, homes, schools, and businesses that had been devastated. A lot of the technology being integrated with these solutions can be deployed almost immediately. I think that as the fire agencies begin to get their hands on more of this technology, we’re going to have a hopefully relatively quick uptake. Cameras, sensors, satellite data — a lot of this is already being deployed. So we’re looking at how quickly and under what conditions it can help improve our detection. And then we have other components that I would say are going to have a longer timeline to full deployment.
Mitch Ratcliffe 7:56
It sounds like part of the problem, then, is just knitting all this together. Does that also apply to areas outside of major cities? Do we have the resources to do this on a nationwide basis?
Andrea Santy 8:10
Yeah, absolutely. We’re doing our testing for our space-based competition in Australia, so we’re looking at how you detect fires over vast areas from satellites as quickly as possible and deliver that information down within 10 minutes, with 15-minute updates. For our autonomous track, we’re testing in Alaska — so it will definitely be a real-world scenario where we can understand the capabilities of these technologies in forested areas, in really vast terrain, and under different environmental conditions. Part of why we’re working with these partners is because they’re great partners, but it also allows us to validate this technology under real-world, challenging conditions.
Mitch Ratcliffe 9:03
So how does the wildfire strategy change when this technology is in place? You’ve already mentioned that the climate crisis is accelerating the size and pace of these fires. Is the goal to suppress more fires earlier so that available resources can be deployed to those that actually break out? What’s the big-picture change in policy here?
Andrea Santy 9:26
XPRIZE really decided to double down on early detection and autonomous response, and we have two tracks. I’ll talk about the detection piece first because it’s digestible for everyone. Every wildfire starts small. They don’t start as a huge catastrophe — they start small, often in pretty remote areas. Sometimes they burn really fast, sometimes slower, depending on the conditions. But if you can address a wildfire at its very smallest phase, essentially post-ignition, that gives you the best chance to address it — either through autonomous suppression systems or through your fire service. If you have more eyes, ears, and noses on the landscape, the better your chance of getting that alert as soon as possible, which allows the fire service to decide how to prioritize their resources.
The second component we’re advancing is autonomous detection and response. Sensors and cameras handle the detection; the autonomous response system deploys, verifies there is a fire — that it’s not a barbecue but an actual wildfire that needs suppression — and places suppressant fully autonomously. That’s what we’re going to be testing in Alaska: can they execute this full end-to-end system? Is the technology integrated? Will it reach the scale and scope of the challenge and the geography? Because 1,000 square kilometers — which is our testing area — is roughly the size of San Antonio, Texas. The teams will have to find multiple fires and demonstrate persistent monitoring and persistent response. Imagine having a fire starting in a ravine: if you can get something out there in minutes, your chance of knocking it down — even just deterring the spread enough that firefighters can arrive — we hope will be a game changer.
Mitch Ratcliffe 12:13
We’re talking about autonomous drones. But one of the things that happened in the LA wildfire was that Santa Ana winds were so extreme, fixed-wing aircraft couldn’t fly. Can a drone perform in those conditions?
Andrea Santy 12:27
During our semi-final testing, our team traveled the world to observe these solutions in action. While not at scale, each of the five finalists was able to demonstrate that they could detect a fire, navigate to it, and suppress it fully autonomously over a small area. Coincidentally, relatively strong winds followed us — nothing like the Santa Ana winds, but we had 40-mile-per-hour winds pretty consistently during testing. It was odd, but it was helpful in terms of validating the technology.
Because you don’t have a human pilot, it’s not that helicopters and planes can’t fly — it’s that they can’t fly in that type of wind without putting a human at risk. This approach removes at least that human element. It’s going to continue to be a challenge, but many of the drones have a relatively high wind tolerance, and as the technology improves, the systems themselves are providing the input to stay balanced.
Mitch Ratcliffe 13:54
These systems are also being combined with sensor networks. Can you talk about how those are being deployed?
Andrea Santy 14:01
Some teams are really focused on ultra-early detection by deploying a sensor network — many, many sensors connected through a mesh network — allowing small, distributed sensors across a large area, which gives you great coverage. All of the different teams are competing under the same scenario, so we’ll get to see which technologies work under which conditions. There’s no single silver bullet that works in every condition, every geography, and every forest type. We’re also working on a pilot phase post-competition so the teams can continue to test and deploy, gaining even better understanding. Building trust with fire agencies — so they know what the technology can do under critical situations — is really important.
Mitch Ratcliffe 15:24
Do the fire agencies participate in these trials as well?
Andrea Santy 15:28
Absolutely. We have partners from different fire agencies in Australia — we’re doing our testing with the Rural Fire Service of New South Wales, which is a testing partner. Many of our judges come from different fire agencies across the United States and around the world. From the beginning, that was really an ethos we set forward — making sure this was done hand in hand with the fire agencies.
Mitch Ratcliffe 15:59
You’ve mentioned decoy fires. I’m curious how the trials will incorporate them. You mentioned barbecues — are you going to have people setting up small fires to lure the competition’s sensors?
Andrea Santy 16:11
I can’t say too much because testing hasn’t happened — I can’t give away the secret sauce. But yes — the teams do know they will have decoys and will need to ensure their technology ignores them. It can be anything from something flapping in the wind that resembles the color of fire all the way to barbecues or pile burns — anything that would confuse the technology.
Mitch Ratcliffe 16:52
And that could happen any day of the year. Really interesting. One of the most compelling things about the competition is the breadth of sources of ideas and the range of approaches — including even a high school team from Valley Christian High School in San Jose. What does that diversity tell us about where wildfire innovation will actually come from?
Andrea Santy 17:15
At XPRIZE, we believe that ideas can come from anyone, anywhere, and I think XPRIZE Wildfire really demonstrates what that looks like. We had teams from over 55 different countries enter the competition. We currently have six countries represented through our finals teams, and the range spans from Valley Christian — a high school team — through universities, startups, and all the way up to major industry. That truly spans the whole spectrum.
What I really love about our competition is that for many of the teams, this is both a company and a passion. Wildfires happen in so many places, and so many teams have been personally impacted. The high school team talked about growing up in areas where wildfires are a constant presence — they are very cognizant of the need for these solutions. Something remarkable: one in six Americans live in an area of wildfire risk, and 25% of Californians.
Mitch Ratcliffe 18:57
It’s a very tangible problem for so many of us, particularly in the West. And the smoke from fires in Canada is now familiar on the East Coast — it’s changed the very shape of life. This is a great place to take a quick commercial break. We’ll be right back.
[COMMERCIAL BREAK]
Welcome back to Sustainability In Your Ear. Let’s return to my discussion with Andrea Santy. She is Program Director of XPRIZE Wildfire — a competition headed into its final year with two groups of finalists vying to win shares of an $11 million prize to help commercialize their technologies.
Andrea, the autonomous competition requires teams to detect and suppress a high-risk wildfire in a 1,000-square-kilometer area — roughly the size of San Antonio — and do it within 10 minutes, while ignoring decoy fires. That’s four times faster than current best practices. Have any of the teams met that benchmark yet in the trials?
Andrea Santy 19:57
As I mentioned, the five teams advancing to finals all demonstrated they have end-to-end solutions to autonomously detect, navigate, and suppress a fire. Our semi-final testing was at a much smaller scale, and while some teams did it in less than 10 minutes, this finals competition is at a very large scale — and it is going to be challenging. Every XPRIZE is very audacious. We really want to push the limits, but we’re very confident we’re going to have a team that can do it. Still to be seen, but that is what finals is for.
Mitch Ratcliffe 20:42
Absolutely. It’s great that we’re testing in such diverse settings. Australia and Alaska seem very different. Is that actually the case, or are wildfire conditions globally roughly the same?
Andrea Santy 20:59
Very different. In Alaska, it will be wildfire season, and we’re testing in an area of much lower risk. The vegetation is different. The geography is different. The fuels — the plants and trees — are different. In Australia, the teams will be arriving as it comes out of summer and goes into fall, which means we don’t actually know exactly which specific days we’ll test, because the Rural Fire Service has to execute prescribed burns when it’s safe. We have a two-week testing window, with five planned days of testing, and approximately 20 fires of varying sizes that the teams will need to identify under different conditions and vegetation types.
Mitch Ratcliffe 22:11
Let’s talk a bit about the space-based prize. Lockheed Martin is adding a million dollars for the teams that can demonstrate the fastest and most accurate detection. Is detection turning out to be the harder technical problem — or is it the transition from detection to action, that coordination piece we talked about?
Andrea Santy 22:40
Lockheed Martin is supporting the autonomous wildfire response track — which we call Track B. The autonomous track requires teams to detect, navigate, and suppress, with all teams using drones. There’s a lot of different detection technology, from sensors that detect particulates up to cameras, and sensors and cameras mounted on drones.
Getting that detection into these autonomous response systems is really the step change — having something that communicates without human intervention, with drones that can fly under wind conditions and navigate to the right location, confirm there’s a fire, and then suppress it accurately. The teams will be testing on a moving fire — not a barrel of fire, but an actual fire that will be dynamic and small-scale but moving. That’s really challenging and requires quite a bit of system training. During semi-finals, accurately hitting the target was one of the harder challenges.
Mitch Ratcliffe 24:43
As you talk about it, it sounds like the transition from detection to addressing the fire appropriately — choosing the right suppression mechanism — is something you’ll continue to work on.
Andrea Santy 24:58
The teams are definitely still working on their systems. They have until June to have all of their systems working. Yeah, it requires a lot of different components.
Mitch Ratcliffe 25:20
And obviously that’s part of the bigger challenge — coordinating technological responses to a changing climate and acute situations like fire. As you observe the environment with these systems, are we also potentially identifying opportunities for prescribed burns in order to reduce fire risk?
Andrea Santy 25:45
Absolutely. While our competition is focused on detection and response to incipient-stage wildfires, I do think this technology can be utilized across many different scenarios — including prescribed burns, where you want to monitor large burn areas to ensure nothing escapes. That is definitely a use case, and anything that reduces our risk. Personally, I think it could provide peace of mind: if you have something on hand that can prevent a prescribed fire from spreading when weather conditions change unexpectedly, that’s enormously valuable.
Mitch Ratcliffe 26:43
Indigenous communities have managed fire for millennia using these kinds of burning practices. Have you engaged with tribal fire practitioners? Do they see autonomous technology as complementary to, or in tension with, their traditional fire stewardship programs?
Andrea Santy 27:02
We have engaged with some. I was just at a meeting where I was able to meet with a representative from an indigenous community in Canada, and they are actually going to pilot-test one of the team’s technologies — specifically a team with a heavy-lift drone. It was really exciting to talk with them and learn more about how they envision it being used. Their community is quite remote, and understanding how this technology could work within their context was a great conversation.
Mitch Ratcliffe 27:41
When I think about the swarm of drones approach to fire management, the regulatory landscape seems like a significant challenge. The FAA has been grappling with drone airspace management. Does the regulatory framework need to change significantly to accommodate these systems?
Andrea Santy 28:06
That’s an excellent question. Current regulations and protocol don’t allow drones in airspace with manned aircraft. As the technology gets better, there are definitely ways this can happen — there are pilots and tests already occurring with other partners looking at shared airspace for heavy-lift drones operating at higher altitudes. Beyond visual line of sight is one area where the testing is definitely ahead of where the regulations are.
Mitch Ratcliffe 28:55
What has your conservation career taught you about how technology deployment can shape our relationship with nature?
Andrea Santy 29:07
I got into this position in part because many of the projects I was working on at the World Wildlife Fund were being lost to wildfire, and I felt we hadn’t really understood the impact of wildfires on conservation. Wildfires are now the main driver of deforestation globally, having surpassed agriculture. In places like the Amazon, the Congo, and parts of tropical East Asia, there’s such critical biodiversity — and I think if we can use technology to monitor these areas, understand where fires are happening, and deploy appropriate responses, my hope is that we can save really, really important places. There are endemic species that only live in very, very small areas, and one fire could wipe out an entire species.
I also worked for a long time on projects where your goal was 20 to 50 years away. Being able to work with XPRIZE, where in three years we’ve seen an absolute transformation in both what the technology can do and how people understand what technology is for — I think we need more of these competitions, more technology applied to conservation problems. I’m really hopeful.
Mitch Ratcliffe 31:23
After three years with XPRIZE Wildfire, do you feel like we can turn back the rising incidence of wildfire and all the costs we’re seeing pile up when cities burn?
Andrea Santy 31:35
I think so. Communities and citizens around the world are understanding the problem at a deeper level. This is going to be all hands on deck. You need citizens and homeowners making sure they have zone zero — no vegetation around their homes. You need communities, city and state incentives, industry engagement. You need prescribed fire and better forest management policies that allow good fire on the landscape, and communities that encourage it. All of these factors together are what will get us to a new paradigm.
Mitch Ratcliffe 32:29
You mentioned raising awareness — this competition actually sounds like really good TV. Have you thought about how to tell this story of wildfire innovation so that people can get engaged with and behind this kind of activity?
Andrea Santy 32:49
We’ve discussed at length how we would be able to document some of the testing. For the autonomous wildfire response, it is a very big, vast area, and turning it into good TV is probably a step beyond us — but I think the teams have amazing stories to tell. We’re going to capture a lot of imagery to share that story out. We have a resource page that provides a lot of different information to homeowners and individuals about other really amazing organizations doing great work in the wildfire space.
Mitch Ratcliffe 33:47
How can our listeners follow along as you complete the project?
Andrea Santy 33:51
We’d love to have them follow along. The easiest way is xprize.org/wildfire — we have lots of information about the competition and the teams, lookbooks to learn about which teams are competing, social media updates, and a newsletter you can subscribe to. During the testing events we’ll be sharing quite a bit of good information. The events are in fairly remote, closed-system locations, so we can’t invite everyone there — but we’ll definitely be exploring how to make sure as many people as possible can get their eyes on what we’re doing.
Mitch Ratcliffe 34:42
Andrea, thank you very much for spending time with us today. It’s been a really interesting conversation.
Andrea Santy 34:48
Thank you so much. We hope all your listeners think deeply about wildfire and what they can do. Our goal is that collectively we can all work together to reduce this wildfire risk and keep good fire on the landscape.
[COMMERCIAL BREAK]
Mitch Ratcliffe 35:11
Welcome back to Sustainability In Your Ear. You’ve been listening to my conversation with Andrea Santy, Program Director of XPRIZE Wildfire, an $11 million global competition now in its final year. Learn more and follow the finalists at xprize.org/competitions/wildfire.
This conversation revealed, at least for me, that solutions to wildfire are arriving — but perhaps faster than the systems built to receive them can accept and use them. We’ll need more public funding to deploy these technologies, and right now we’re moving in the wrong direction. As wildfire damage grows, total federal wildfire spending is holding roughly flat at around $7 billion a year. However, the Trump administration’s FY 2026 budget proposes eliminating the Forest Service’s state fire capacity grants, cutting vegetation and watershed management programs by 30%, and zeroing out the $300 million in forest research funding that was in the budget previously. So we’re maintaining the suppression budget while cutting the prevention, detection, and research infrastructure that could reduce what we have to suppress.
Fortunately, we have XPRIZE Wildfire to take on some of the burden — but it’s not enough. Consider what Andrea said about early detection: every wildfire does start small. If autonomous systems can get suppressant on a fire quickly enough, it might not even need to be fully extinguished — just deterred enough that firefighters can arrive to finish the job. The technology to do that end-to-end and autonomously is already being demonstrated in the field. But Andrea was equally direct about what’s lagging: the testing is ahead of where the regulations are.
Consider autonomous drones operating beyond visual line of sight and coordinating with manned aircraft during active fire emergencies. For that to work, the FAA’s frameworks for widespread drone operations need to be reinvented. The recent closure of El Paso International Airport over nearby counter-drone laser testing is evidence of how unprepared we truly are for the innovations that are coming.
In short, the engineering has arrived, but institutions need support to integrate that engineering into their operations. A similar gap is evident in who’s doing the innovating: teams from over 55 countries entered this competition, and a high school team from San Jose made the finals by solving the problem of locating fires beyond ridgelines using multi-sensor triangulation — not because they had institutional backing, but because they had access to a well-defined problem and the drive to solve it, along with the incentive of XPRIZE’s $11 million award.
The XPRIZE premise that ideas can come from anyone, anywhere — it turns out — is literally true. But recognizing that changes nothing if the regulatory, procurement, and deployment systems still favor incumbents and slow-moving approval processes.
Underlying all these challenges is what Andrea brought to this work from nearly two decades at the World Wildlife Fund: wildfires are now the leading driver of deforestation globally, having surpassed agriculture. The game has changed, but policy is still anchored in now-outdated 20th-century strategies. One fire in the wrong place can drive a species to extinction, or it can burn a city to the ground.
Andrea said she’s hopeful — not because the problem is easy, but because in three years she’s watched a transformation in what technology can do and how people understand what technology is for. That hope is well earned. But it will only translate into outcomes if institutions move at the speed the crisis demands — citizens, homeowners, communities, industries, and policy, all moving together. The competition creates urgency; the systems around it need to act on and use the innovations being delivered.
So stay tuned for more conversations with people actually making sustainability happen, and I hope you’ll check out our archive of more than 540 episodes. There’s something worth sharing with anyone you know. Writing a review on your favorite podcast platform will help your neighbors find us — because, folks, you are the amplifiers that spread ideas to create less waste. Please tell your friends, your family, your co-workers, and the people you meet on the street that they can find Sustainability In Your Ear on Apple Podcasts, Spotify, iHeartRadio, Audible, or wherever they get their podcast goodness.
Thank you for your support. I’m Mitch Ratcliffe. This is Sustainability In Your Ear, and we will be back with another innovator interview soon. In the meantime, folks — take care of yourself, take care of one another, and let’s all take care of this beautiful planet of ours. Have a green day.

Best of Earth911 Podcast: Adapting to Smoke Season’s Health Impacts With Dr. James Crooks
Smoke season is back, and getting more intense every year. Tune into this “Best of” discussion with James Crooks, Ph.D., an environmental epidemiologist with National Jewish Health’s Division of Biostatistics and Bioinformatics in Denver, who explains his research on the impact of wildfire smoke on the ozone concentrations at ground level in Colorado. Elevated ozone levels contribute to the rising incidence of asthma and diabetes, among other conditions. Dr. Crooks found that while ozone increased only 1% compared to pre-wildfire levels, the impacts are widely felt, especially in Hispanic and historically underserved communities. The advent of annual smoke seasons and rising levels of air pollution globally make this an important conversation. He shares his advice on how to protect family members from air pollution and the prospects for life in a warmer world, when smoke season will be common in many regions.

Smoke season isn’t just unpleasant, it’s killing too many of us. According to a recent study published in the journal The Lancet Planetary Health, air pollution was directly responsible for the death of 4.5 million people around the world in 2019. A McGill University study released in early May reported that people who lived within 31 miles (50 km) of a wildfire over a 10-year period were found to have a 10% higher incidence of brain tumors and 4.9% more lung cancers. You can learn more about Dr. Crooks and National Jewish Health at nationaljewish.org.

7 Sustainable Bar Stools and Counter Stools To Complete Your Space (2026)
If you’re looking to finish your kitchen, bar area, or other seating arrangement with a set of sustainable bar stools (or counter stools) then you’ve come to the right place.
How To Source Sustainable Bar Stools and Counter Stools
I was looking for sustainable counter stools last year because my husband and I’s apartment had a large countertop and no room for a kitchen table.
We liked how the layout utilized the small space efficiently, making it feel like we had more space than we really did! However it’s not as easy to find beautiful counter stools as it is to find other sorts of dining chairs!
After borrowing my parent’s barstools for a few months, we came across the perfect set of mid-century modern-esque secondhand counter stools from the peer-to-peer resale app OfferUp.
There are many ways to source sustainable bar stools or counter stools. And which way is right for you depends on your budget and circumstances.
Secondhand Apps
This option is usually the cheapest, but may require a lot of time searching and picking up the items.
We used OfferUp, because we were on a budget, had the ability to wait (since we could borrow stools in the meantime), and weren’t ready to invest in our “forever home” — we don’t know if our future living spaces will require counter stools.
Curated Secondhand Sites
These tend to be the second most affordable option for counter stools, bar stools, or any other piece of furniture. You pay a bit of a premium over something like OfferUp or Facebook Marketplace, because the pieces are more curated, the photography is typically way better, and some places may even handle the shipping and logistics for you!
Here are a couple to check out:
- AptDeco: Advertised as the easiest way to shop secondhand furniture, AptDeco provides a professional delivery service, including pickup, delivery, and assembly within the contiguous U.S.
- Chairish: mecca for vintage furniture (typically more expensive)
New Eco-Friendly Bar Stools and Counter Stools
You may want to shop for new sustainable counter stools and bar stools if you don’t have as much time to hunt for treasures on the secondhand market, want to invest in a long-term piece of furniture, or have a very specific set of aesthetic preferences.
You might also look for new eco-friendly counter stool options if you want to make sure your stools are non-toxic, and made without harmful chemicals. You’ll see some certifications mentioned throughout. Here’s a quick cheatsheet on what they do (and don’t do).
FSC Certified: the wood sourcing was responsibly managed (not a finish, foam, or textile guarantee)
CertiPUR-US®: third-party verification that foam (like cushioned seat padding) is made without ozone depleters, PBDE flame retardants, mercury, lead, or formaldehyde, and meets low VOC emission standards; it’s a foam-specific certification, not a wood or fabric one
OEKO-TEX® STANDARD 100: tests the finished textile (like wool or cotton upholstery) for harmful substances against human-ecological safety limits; this is a product-level fabric certification, and does not cover the wood or metal parts of the furniture
Below are some vetted resources for finding sustainable bar and counter stools! Transparency note: this guide contains affiliate links. As always we only feature brands that meet strict criteria for sustainability that we love — and that we think you’ll love too.

How Safe Are Secondhand Used Pet Supplies?
A used dog crate can save you $80 and keep a perfectly good piece of gear out of a landfill. A used food bowl with a few hairline scratches can seed your pet’s water with bacteria for months. The difference between a smart secondhand buy and a risky one usually comes down to two questions: what the item is made of, and whether you can actually clean it.
Americans spent $158 billion on their pets in 2025, and a growing share are looking for ways to spend less; the American Pet Products Association found roughly 22% of owners cut back on pet spending last year. Reused pet gear sits right at the intersection of saving money and cutting waste. But pets add a wrinkle that used furniture or clothing doesn’t: some of the germs that ride along on old bowls, beds, and toys are remarkably hard to kill, and the popular vinegar-and-soap cleaning advice doesn’t do what most people think it does.
This article contains affiliate links. If you purchase an item through one of these links, we receive a small commission that helps fund our Recycling Directory.
Why Buying Used Makes Sense
The resale habit that reshaped clothing is spreading to durable goods. Pet supplies are a natural fit: crates, carriers, and hard toys are built to last far longer than one animal’s use of them.
Keeping those items in circulation matters, because pet gear leans heavily on plastic. Pet products generate an estimated 300 million pounds of plastic waste a year in North America, according to Earth.Org, and most worn-out toys and beds aren’t recyclable through curbside programs. Every crate or bowl bought secondhand is one that didn’t have to be manufactured, and one that isn’t clogging a landfill.
A few manufacturers are building reuse into the product itself. West Paw runs a closed-loop reuse program called Join the Loop, which grinds down worn Zogoflex toys and remakes them, and Petmate now makes kennels from roughly 95% recycled polypropylene. When you can’t find a safe used version of what you need, durable, recycled-content, take-back-eligible gear is the next-best circular choice.

Start With the Material, Not the Price Tag
The single most useful rule for secondhand pet shopping is this: hard, nonporous items can be cleaned and disinfected; soft, porous ones often can’t. Stainless steel, glass, glazed ceramic, and smooth hard plastic have surfaces you can scrub and sanitize down to bare material. Fabric, foam, wood, rope, and sisal soak up saliva, urine, and whatever lived in them before, and no amount of wiping reaches all the way in.
Use this as a quick field guide when you’re standing over a yard-sale table:
| Item | Buy used with confidence | Think twice — or skip |
|---|---|---|
| Food & water bowls | Stainless steel, glass, or glazed ceramic with no cracks or chips | Any plastic bowl, or ceramic that is cracked, chipped, or crazed |
| Crates & carriers | Metal or hard-plastic crates with intact joints, latches, and no cracks | Cracked plastic, bent wire, loose handles; any airline travel crate (buy new) |
| Toys | Hard rubber and nylon chews with no gouges; treat-dispensers you can scrub | Chewed, gouged, or split toys; rope and plush toys from unknown homes |
| Beds & clothing | Machine-washable fabric you can run hot and dry on high heat | Foam beds you can’t fully wash; anything torn enough to be a choking hazard |
| Cat trees & scratchers | Frames you can wipe down; replaceable sisal or cardboard inserts | Carpet-covered posts saturated with another animal’s scent — usually not worth it |
| Aquariums & tanks | Glass tanks that hold water after a leak test; check seams and silicone seals | Tanks with cracked glass or failing seals; anything you can’t leak-test first |
| Leashes, collars & harnesses | Nylon or biothane with sound stitching and working hardware | Frayed webbing, cracked buckles, or rusted clasps that could fail |
Food and Water Bowls
Stainless steel, glass, and glazed ceramic bowls are ideal secondhand buys because they’re durable, and boiling water or a dishwasher cycle sanitizes them completely. Just check ceramic for cracks, chips, and crazing (that fine web of surface cracks in old glaze), any of which can trap bacteria and, in some imported glazes, leach lead.
Skip used plastic bowls entirely. Even hairline scratches in plastic harbor bacteria that can’t be removed by routine washing, and the bacteria that live in a pet’s mouth recolonize those grooves fast. For example, the Cornell Feline Health Center notes that 70–90% of cats carry Pasteurella multocida, a pathogen which can cause wound infections in people.
A new stainless bowl costs a few dollars and lasts for years, so this is one place not to economize.
Crates and Carriers
Metal and hard-plastic crates are among the best secondhand values in pet care. Inspect your options for cracks, sharp edges, missing screws, weak joints, and a carrying handle that’s loose or damaged. On wire crates, check that the door latches securely and the pan slides in flush.
Fabric crates need intact seams and zippers that fasten smoothly; a failed zipper on the road can lead to a lost pet. One firm exception: don’t buy a used airline travel crate. Most carriers require a new, IATA-compliant crate for animals flying as cargo, and a secondhand one may not meet current standards.
Beds, Clothing, and Soft Toys
Fabric items can be great buys if, and only if, you can launder them properly. Wash on the hottest setting the fabric allows and dry on high heat; a full hot wash-and-dry cycle kills fleas at every life stage, along with their eggs. Use a plant-based, pet-safe detergent so you’re not leaving fragrance and residue against your pet’s skin.
Inspect for rips and loose parts that could become choking hazards and be realistic about foam beds; if you can’t remove and wash the cover and you can’t wash the core, you can’t truly clean it.
Plush and rope toys are the least recommended soft items to buy used, because their fibers can hold saliva-borne bacteria and even worm eggs that laundering doesn’t fully kill.
Cat Trees, Scratchers, and the Scent Problem
Cats and dogs mark territory with scent, and a secondhand scratching post or cat tree can come pre-loaded with another animal’s signature. Some cats respond by refusing the item; others try to overwrite it, sometimes by urine-marking. Carpet- and sisal-covered posts are also porous and nearly impossible to disinfect.
Give any soft-covered item the sniff tests a cat would give it. If you can smell the previous animal, your pet certainly will. A better secondhand strategy is to buy a solid frame you can wipe down and add fresh sisal rope or replaceable cardboard inserts yourself.
The Cleaning Advice Most Guides Get Wrong
Here’s the part worth slowing down for. Soap and water, including natural Castile soap, and vinegar are fine for everyday grime and routine bacteria. Physically scrubbing an item removes most of what’s on it, and for gear coming from a healthy household, that plus a hot wash and sunlight is usually enough.
But vinegar is not a disinfectant against the pathogens that matter most in used pet gear. The viruses of real concern, including canine parvovirus and feline panleukopenia, are nonenveloped, meaning they lack the fatty outer coat that makes other germs easy to kill. That structure lets them resist most common cleaners, including vinegar and quaternary ammonium products, and survive in the environment for a long time.
|
The good news for anyone who came to secondhand shopping for environmental reasons: the most effective option is also one of the greenest. Accelerated hydrogen peroxide (AHP), which is sold to shelters and vets under the brand Rescue, kills parvovirus yet breaks down into water and oxygen, carries Green Seal and GREENGUARD Gold certifications, and doesn’t require the ventilation and skin protection bleach does. It’s the rare case where the responsible choice and the effective choice are the same bottle.
How Long Germs Actually Linger
Older advice often says viruses and parasites survive on secondhand items for “up to a month.” For the tough ones, that’s a serious underestimate. Canine parvovirus can persist in a contaminated environment for as long as seven months, according to the Indiana State Board of Animal Health, and veterinary sources put its outdoor survival at up to a year under cool, shaded conditions. Fleas and their eggs can stay viable in bedding for weeks. That long tail infection potential is why an effective disinfection method, not just “give it a wash,” matters.
When to Skip Secondhand Altogether
A few situations tilt the math toward buying new, or passing entirely:
- You have an unvaccinated puppy or kitten. Young animals are most vulnerable to exactly the viruses that resist cleaning. Until vaccinations are complete, favor new, easily sanitized gear.
- The item comes from a home with a known illness. If a previous pet had parvo, panleukopenia, ringworm, or a flea infestation, skip any porous item and disinfect hard ones with an AHP or bleach solution.
- You can’t clean it to the core. Foam beds, saturated cat trees, and gouged chew toys can’t be reliably disinfected. When in doubt, they go.
- The damage is structural. Cracked crates, frayed harness webbing, failing tank seals, and chipped ceramic aren’t bargains, they’re hazards that can harm your pet.
Products Worth Knowing About
A short, practical kit makes secondhand pet shopping safe without much fuss.
- Accelerated hydrogen peroxide disinfectant (e.g., Rescue). The eco-forward way to kill parvovirus and panleukopenia on hard, nonporous gear.
- Enzymatic odor cleaner. Breaks down the proteins in urine and scent marks that plain soap leaves behind, which is useful for reclaiming a lightly-marked crate or hard scratcher frame.
- Stainless steel bowls. When a used bowl is plastic or questionable, a new stainless set is inexpensive, dishwasher-safe, and effectively permanent.
- A fine-tooth flea comb. A dollar-store tool that tells you fast whether a secondhand bed or blanket is carrying hitchhikers.
- Durable, recycled-content toys (e.g., West Paw Zogoflex). For the soft-toy gap secondhand can’t safely fill, and they’re take-back recyclable at end of life.
What You Can Do
- Shop by material first. Reach for stainless steel, glass, glazed ceramic, and smooth hard plastic; be cautious with fabric, foam, wood, rope, and sisal.
- Inspect before you buy. Check for cracks, sharp edges, frayed webbing, failed zippers, and chewed-through spots. Structural damage is a dealbreaker.
- Match the cleaning method to the risk. Hot wash and dry for fabric; scrub-and-sanitize for hard items. For anything from a home with illness, use an AHP or bleach solution at full contact time.
- Know when to buy new. Airline crates, food bowls to replace plastic, and gear for unvaccinated young animals are worth buying new.
- Close the loop at the other end. When your own pet gear wears out, donate what’s still usable, and check Earth911’s recycling search for options on what isn’t.
