As climate change intensifies, nations and industries are seeking innovative ways to cut carbon footprints. Carbon credits have emerged as a key tool in this effort. Planting new trees also generates carbon credits. Apart from this, trees reduce carbon dioxide, restore ecosystems and biodiversity, and combat desertification.
MIT’s Climate Portal studied that in 2021, the U.S. released 5.6 billion tons of CO2. To absorb that, over 30 million hectares of trees—about the size of New Mexico are need. It estimated:
- A hectare of trees can absorb 50 tons of carbon, which equals about 180 tons of CO2 in the atmosphere.
But not all trees are the same. Some forests store as little as 10 tons of carbon per hectare, while others store over 1,000. So, planting trees to offset emissions or generate carbon credits is more complicated than it seems.
In this article, we will discuss everything you need to know about planting trees for carbon credits. Let’s study in depth.
How Carbon Credits Are Generated Through Tree Planting
Carbon credits help balance or offset emissions by funding projects that reduce or remove greenhouse gases. Each credit equals one metric ton of CO₂ either captured or avoided.
Tree planting is a popular way to generate carbon credits. When trees are grown specifically to absorb carbon, the project can be certified, and the credits can be sold. Companies and individuals buy these credits to offset their emissions, support sustainability goals, or meet regulations.
This system creates a financial incentive for reforestation, encouraging tree planting worldwide. Beyond carbon storage, forests also clean the air, protect the soil, support wildlife, and regulate water cycles. These extra benefits make tree-based carbon credits even more valuable for the environment and communities.
How Trees Absorb Carbon: The Science of Sequestration
Trees absorb and store carbon through photosynthesis. They take in carbon dioxide, use sunlight for energy, and store that energy as carbohydrates in their trunks, branches, leaves, and roots. As they grow, they lock away more carbon in their biomass.
Mature forests hold large amounts of carbon, but young forests absorb it more quickly as they grow. That’s why afforestation projects often plant fast-growing species to maximize carbon capture in the early years.
Trees also help store carbon in the soil. Their roots improve soil health, increasing organic matter and trapping even more carbon. This combination of tree growth and soil storage makes afforestation a powerful way to fight climate change.
In the first ten years, trees grow quickly and absorb a lot of CO₂. Young trees need plenty of energy to develop strong roots, trunks, and branches. This early growth stage is crucial for their health and long-term strength.

Afforestation vs. Reforestation: What’s the Difference?
While afforestation and reforestation both involve planting trees, they address different environmental challenges and have distinct definitions:
Afforestation
Afforestation means planting forests in areas that have never had them. This process creates new ecosystems, often in degraded or dry lands. These projects work well in places where desertification or land damage has left the land barren. By adding trees, afforestation boosts land productivity and offers new homes for wildlife.
Reforestation
Reforestation is about restoring forests that have been cut down or damaged. This process aims to bring back the ecological balance in areas that once had forests. These areas may have lost trees due to logging, farming, or urban growth. Reforestation projects help rebuild ecosystems, enhance biodiversity, and reduce the impact of deforestation.
Afforestation and reforestation help with carbon sequestration. Afforestation is special because it increases global forest cover in new areas. Reforestation focuses on recovery and restoration, tackling the damage from deforestation.
Carbon credits are generated from afforestation and reforestation projects. These projects track how much CO2 the new trees absorb. Strict monitoring and verification confirm these claims. Once verified, the sequestered carbon turns into carbon credits, which can be sold in carbon markets.
The Role of Afforestation in Carbon Credits Market
Afforestation is vital for the carbon credit market. Tree-planting projects in barren areas capture carbon effectively. Independent organizations verify and certify this process.
Companies buy certified credits to offset their emissions. The revenue from these credits supports more afforestation projects. This creates a self-sustaining cycle that benefits both the environment and project developers.
Afforestation projects align with global climate goals, such as the Paris Agreement. These goals emphasize nature-based solutions for net-zero emissions. By increasing forest cover, countries can meet their NDCs and promote global carbon neutrality.
Challenges and Opportunities of Reducing CO2 Emissions with Trees
Afforestation has many benefits, but it also has challenges. Ensuring the long-term survival of planted forests is crucial, as trees take decades to mature and require consistent care. Poor site selection, lack of maintenance, and climate change can hinder the success of these projects.
An MIT Report revealed that while planting trees could reduce CO2 emissions in about 10 years, deforestation continues at a rapid pace. It also highlighted that from 2015 to 2020, around 10 million hectares of forest were lost each year, with only 4 million hectares being restored.
This is because land is often used for farming, livestock, and mining, making it expensive to plant trees. As a result, not enough trees were planted to significantly reduce CO2 emissions.
Choosing the right tree species is important. Planting non-native or fast-growing trees can harm local ecosystems and reduce biodiversity. To get the best environmental results, afforestation projects should use native species. They should also follow sustainable practices.
Despite these challenges, tree planting projects offer great opportunities:
- New technology like remote sensing and AI makes tracking carbon storage more accurate and transparent.
- Partnerships between governments, businesses, and local communities help expand and sustain afforestation efforts.
- Financial incentives support large-scale tree planting, balancing economic growth with environmental benefits.
To combat rising CO2 emissions, afforestation and reforestation both offer solutions. However, we need to carefully consider where and how to plant trees to make a real difference in reducing CO2 levels.
The United Nations Strategic Plan for Forests
The United Nations Strategic Plan for Forests 2017–2030 was agreed upon in January 2017 and adopted by the UN in April 2017. It sets out six Global Forest Goals and 26 targets to be achieved by 2030.
The plan aims to increase global forest area by 3%, adding 120 million hectares—over twice the size of France. It emphasizes the need for collective action within and outside the UN System to drive meaningful change and support sustainable forest management.
Calculating the Value of a Tree in Carbon Credits
The carbon sequestration capacity of a tree depends on factors such as species, age, growth conditions, and geographic location.
Accurately quantifying this capacity is essential for determining the corresponding carbon credits. Recent research has focused on developing methodologies to estimate CO₂ absorption by urban tree planting projects.
Scientists have also developed formulas to measure carbon absorption from urban greening projects. This shows that carbon credits are needed to support these initiatives for improved environmental results.
The Tree Carbon Calculator uses a formula that estimates the amount of carbon stored in a tree based on its diameter at breast height (DBH), species, and growth conditions. Here’s a simple technique snapshot for calculation.
Funding and Investment: Who Pays for Tree Planting?
Funding for tree planting initiatives comes from various sources, including government programs, private investments, non-governmental organizations, and carbon markets. The voluntary carbon market has seen substantial growth, driven by corporate commitments to sustainability.
- In 2021, the market was valued at $2 billion, with projections suggesting it could reach $100 billion by 2030 and $250 billion by 2050.
Companies are increasingly investing in reforestation projects to offset their emissions. For instance, in early 2025, Microsoft announced a significant deal to restore parts of the Brazilian Amazon and Atlantic forests by purchasing 3.5 million carbon credits over 25 years from Re.green, a Brazilian start-up. This initiative, valued at approximately $200 million, is part of Microsoft’s strategy to become carbon-negative by 2030.
Market Trends: The Demand for Carbon Credits from Tree Planting
The demand for carbon credits from tree planting is growing as more companies and governments focus on tackling climate change.
- Last year a study from Nature.com found that well-planned reforestation projects could remove up to ten times more carbon at a lower cost than previously thought.
- Projects costing less than $20 per ton of CO₂ are considered affordable, making them an attractive option for businesses looking to offset emissions.
However, not all forest carbon offsets are reliable. Research shows that many projects fail to deliver the promised carbon removal, raising concerns about credibility.
Tree planting has strong economic potential, but success depends on accurate carbon valuation, diverse funding, and a solid understanding of the market. Ensuring strict monitoring and verification is key to maintaining trust and maximizing both environmental and financial benefits.
Cost of Planting Trees for CO2 Removal
The same MIT study further revealed how much it costs to remove CO2 by planting trees, considering South America as a case study. They created a “supply curve” to show the cost of removing one ton of CO2 based on how many trees are planted.
This helps us figure out the best places to plant trees, how many we can plant, and the cost involved.
- Point A (South America): Lowest cost: $23 per ton. Plentiful rainfall, low tree planting, and land opportunity costs
- Point B (Amazon Forest, Para, Brazil): Cost: $30 per ton. Plentiful rainfall, but higher tree planting costs
- Point C (Amazon Forest, Mato Grosso, Brazil): Cost: $40 per ton. Higher land opportunity costs
- Point D (Brazilian Cerrado): Highest cost: $90 per ton. Lower forestation potential, higher land opportunity costs
-
Key takeaway: Regional variations in forestation costs are significant, with costs rising as land opportunity and forestation potential decrease.
Practical Guide to Starting a Carbon Credit Tree Planting Project
Embarking on a carbon credit tree planting project involves careful planning, adherence to legal frameworks, and consideration of social and environmental impacts. This guide provides a comprehensive overview to assist in successfully initiating such a project.
Choosing the Right Location: Soil, Climate, and Biodiversity Considerations
Choosing the right site is key to a successful tree-planting project. The soil should be fertile and well-drained to support healthy growth. Climate factors like temperature and rainfall need to match the trees’ needs. Plus, choosing native species helps maintain biodiversity, keeping the ecosystem balanced and connected.
Selecting Tree Species for Maximum Carbon Sequestration
Choosing the right tree species is crucial for carbon storage. Fast-growing trees, like poplars and willows, absorb carbon quickly, while hardwoods, such as oaks and maples, store it longer. Additionally, selecting native species helps ensure resilience and sustainability. A diverse mix not only improves soil health but also supports wildlife habitats, making the ecosystem stronger.
Long-Term Maintenance and Monitoring of Tree Planting Projects
Keeping a tree planting project successful takes ongoing care and monitoring. Regular tasks like watering, mulching, pruning, and pest control keep trees healthy. Tracking growth and survival rates helps measure carbon storage. A strong monitoring plan ensures the project meets its goals and provides reliable data for verification.
Legal and Certification Framework for Tree-Based Carbon Credits
Navigating Through Carbon Credit Certification Processes
Getting certified for tree carbon credits requires recognition from the following standards. The Verified Carbon Standard (VCS) by Verra is the most widely used, providing frameworks for validation and verification. Verra’s VCS Program supports carbon reduction in Agriculture, Forestry, and Other Land Use (AFOLU), which includes:
- Afforestation, Reforestation, and Revegetation (ARR)
- Agricultural Land Management (ALM)
- Improved Forest Management (IFM)
- Reduced Emissions from Deforestation and Degradation (REDD)
- Avoided Conversion of Grasslands and Shrublands (ACoGS)
- Wetlands Restoration and Conservation (WRC)
Other reliable international carbon credit standards include The Gold Standard, The Climate Action Reserve, and The American Carbon Registry.
The certification process involves documenting the project, validating it with an auditor, and verifying carbon sequestration. This ensures the carbon credits are credible and marketable.

Understanding International Standards and Compliance
International standards, like the International Carbon Reduction and Offset Alliance (ICROA), support community-based reforestation and conservation projects that offer both social and environmental benefits.
Projects must show they are sustainable, can measure carbon capture, and provide benefits to local communities to meet these standards. They should also help improve biodiversity. This increases a project’s credibility and opens doors to global carbon markets
The Role of Third-Party Verification in Carbon Credit Projects
Third-party verification ensures carbon credit projects are credible and transparent. Independent verifiers check if projects meet the required standards, confirm carbon storage claims, and make sure social and environmental protections are in place.
This process builds trust with stakeholders and buyers, proving that the credits reflect real emission reductions.
Social and Environmental Impacts of Tree Planting Projects
Community Engagement and Local Benefits
Involving local communities in tree-planting projects helps them succeed. When locals help plan and carry out the work, they get job opportunities and improve their lives. These projects also raise environmental awareness. By focusing on local involvement, projects create a sense of ownership, build stronger communities, and last longer.
Biodiversity and Ecosystem Advantages
Afforestation helps capture carbon and improves biodiversity. New forests provide homes for animals and increase species variety. They also fix damaged ecosystems. Other benefits include cleaner water, better soils, and natural services like pollination and climate control. Focusing on healthy ecosystems boosts these benefits.
Addressing Potential Risks and Criticisms of Tree-Based Carbon Credits
Tree-based carbon credits face challenges. These include permanence, additionality, and social impacts. To store carbon long-term, we must protect forests from deforestation and disasters. Additionality means proving the project wouldn’t occur without carbon credit funding.
Therefore, social issues like displacement and unfair land use should be addressed to benefit the local communities. Notably, transparency and best practices help build trust and credibility.
Starting a carbon credit tree planting project needs careful planning concerning ecological, legal, and social factors. As these projects help combat climate change they follow specific guidelines and involve stakeholders. Additionally, they offer lasting benefits for the environment and local communities.
Future Outlook and Trends in Tree Planting for Carbon Credits
Technological Advancements in Monitoring Tree Growth and Carbon Sequestration
New technologies like satellite imagery and AI-powered tools are transforming how tree growth and carbon capture are tracked. These innovations improve accuracy, lower costs, and enhance transparency, making it easier to verify carbon credits.
For example: Planet Labs PBC a leading provider of global, daily satellite imagery and geospatial solutions announced that they have signed a multi-year, seven-figure deal with Laconic, a company leading a global shift in climate finance, empowering governments to monetize natural carbon assets through its Sovereign Carbon securitization platform.
In this deal, Laconic can use Planet’s 3-meter Forest Carbon Monitoring product and 30-meter Forest Carbon product for the next three years.

The Evolving Market: Predictions for Tree-Based Carbon Credits
As companies and governments push toward net-zero goals, demand for carbon credits is expected to rise. Tree-based credits will stay in demand due to their added ecological and social benefits. However, stricter regulations and increased scrutiny will require stronger verification standards.
- LATEST DEVELOPMENTS:
Companies like Microsoft and Meta are investing in forest carbon credits to reach their sustainability goals. Some recent developments include:
- Microsoft Signs Groundbreaking 7MT Carbon Credits Deal with U.S.-Based Chestnut Carbon
- Meta and WRI Unveiled AI-Powered Global Tree Canopy Map
The Role of Policy Changes in Shaping the Future of Carbon Credits
Government policies and international agreements will play a major role in shaping the future of tree-based carbon credits. Incentives like subsidies and tax breaks will encourage reforestation, while stricter regulations will ensure higher credibility in carbon credit markets.
For example, by the end of 2024, REDD+ forest reference emission level/forest reference level submissions cover approximately 1.7 billion hectares. This is over 90% of tropical forests and more than 75% of forests in developing countries. The submissions feature different ecosystems. These include Mongolia’s boreal forests, Malawi’s dry forests, and tropical rainforests.
For over 10 years, the UN Climate Change Secretariat has assessed REDD+ activities. So far, 63 developing countries have reported their efforts. Because of these activities, 23 countries have cut nearly 14 billion tons of CO2. That’s about 2.5 times the total greenhouse gas emissions of the U.S. in 2022. These countries are now eligible for results-based finance.

A few months ago I went to a climate change forum at the Center for Brooklyn History. The panel I attended, “Confronting Climate Change: Understanding Deniers,” featured the prominent climate activist, Bill McKibben.

I was curious to hear McKibben’s take on climate change deniers. I don’t regard the true deniers as a big problem – they’re only 11-15% of our country, according to most polls. Rather, I wondered if McKibben would label as “climate deniers” people who agree that climate change is a significant problem but disagree with his framing and his proposed solutions. I have worked for decades on energy and climate matters as an energy lawyer. Now, more than ever, I believe that to address climate change we need to build a big tent.
In the Q&A I tested where McKibben is on this by asking if he would label as a climate denier someone who subscribes to the main tenets of climate change science yet holds that natural gas has a role to play as a bridge fuel. (Our exchange starts at 1:12:45 of the video.)
This could have been a chance for McKibben to make clear that such a view isn’t climate denialism, even if he feels it’s misguided. But he punted, saying “I don’t care whether they’re deniers or not.” For good measure, he threw in his long-standing refrain that swapping coal for natural gas makes climate change worse, despite coal’s far higher carbon content per unit of energy.
674-MW methane-powered generating station, Salem, MA.
As you can hear in the recording, McKibben’s claim that gas is worse than coal draws on the work of Cornell scientist Robert Howarth. Yet McKibben didn’t mention that Howarth’s work is controversial and disputed by many scientists. The crux of the dispute is whether methane’s impact on warming should be measured with a 20-year or 100-year time frame.
Methane is a relatively short-lived greenhouse gas, with a lifetime of around 10 years, versus the 100-year life applicable to carbon dioxide. But each ton of methane is far more potent while in the atmosphere, trapping roughly 100 times as much heat as a ton of CO2. These cross-cutting facts about atmospheric methane — shorter life but greater potency than CO2 — have resulted in two opposing camps: one insisting on a 20-year timeframe for greenhouse gas accounting, the other adhering to the established 100-year frame. This matters because with a 20-year timeframe, generating electricity with natural gas (which, chemically speaking, is essentially all methane) is more damaging to climate than coal-fired electricity.
McKibben blew past this dispute. To hear him at the Center for Brooklyn History, one would have no inkling that there’s an active disagreement over which timeframe to use, that there are staunch climate activists who favor the 100-year time frame, and that the Intergovernmental Panel on Climate Change (IPCC) generally uses the 100-year timeframe.
McKibben’s latest (2025) book. Published by W.W. Norton & Company.
McKibben also insisted that a discussion about natural gas’s potential role in mitigating climate change as a replacement for coal is irrelevant because solar “is now our cheapest resource.” McKibben’s claim, of course, suffuses “Here Comes the Sun,” his 2025 book that extols solar power as the cheapest solution for all of our energy needs. But this too is questionable, because it’s based on cost comparisons between solar farms and natural gas power plants (or nuclear power plants) that fail to consider that electricity supply and delivery is a complex system of wires and plants rather than individual power plants. Based on his remarks, McKibben is choosing to ignore studies such as the comprehensive 2025 report from the Clean Air Task Force that concluded that plant-level cost comparison “is a good metric to track historical technology cost evolution [but] is not an appropriate tool to use in the context of long-term planning and policymaking for deep decarbonization.” And the task force is not alone in finding that when electricity is treated as a system, solar loses its place as the cheapest low-carbon resource.
The dogmatism McKibben displayed at the Brooklyn meeting was unfortunate. We’re in a time when efforts to combat climate change are in retreat. A unified front is required to turn the tide. Instead of doubling down on absolutist positions, activists like McKibben who seem convinced that the solution to climate change is all-renewables, end of discussion, should be seeking common ground with others who want climate action but believe that nuclear power and natural gas must also play a role.

Climate change activists need to build a bigger tent, rather than call anyone who disagrees with their positions a climate change denier. It is striking that McKibben stuck to his guns after saying in the same talk that the most important goal for everyone right now is to help climate change realists win more House and Senate seats in this year’s midterms. As some have noted, an absolutist position on natural gas appears less likely to achieve that win and politicians are following that advice.
Will McKibben evolve? He has demonstrated that he knows how to build a national climate movement centered around issues like divestment. Given the current political situation, he should focus on building an even bigger tent by welcoming all of the 85% who believe that we need to address climate change but do not agree with his ideological positions.

Image generated with Claude. Why have we juxtaposed a bicycle with balcony solar? Read on.
First it was Plug-In Solar. Then it was Balcony Solar. Now it’s Guerrilla Solar, at least according to Inside Climate News, which yesterday proclaimed that The ‘Guerrilla Solar’ Era Has Arrived.
“It,” of course, is Modular solar panels. They’re the hot new photovoltaic solution: cheap enough to buy at Home Depot, easy to hang or prop to catch maximum rays, and small enough to fit on a balcony (if you’ve got one) and plug into your “home grid.” But, alas, too meager a generator of electricity to be more than a bit player in decarbonizing most U.S. homes.
How do I know? I’ve done the math.
A standard, lower-end 220-watt balcony solar array will produce 337 kilowatt-hours a year, or 28 kWh a month averaged over the course of a year. That’s for a 220W unit measuring 3.5 feet by 3.5 feet. (220W x 1/1000 x 17.5% x 8760 hours per year = 337 kWh. Calculation assumes a 17.5% full-year capacity factor, which is arguably generous for New York, where I live. )
Our balcony solar mashup. Top: an install in Germany. Bottom: Home Depot advert.
A typical U.S. home consumes 10,500 kWh a year, or 28 to 29 kWh per day, says Solartech, drawing on U.S. Energy Information Administration data. That puts a home’s daily power needs on par with a balcony solar unit’s monthly output. In effect, once each month the balcony array gifts a homeowner or renter a bit more than day’s full complement of electricity. And earth’s atmosphere gets the same respite: a 3 percent reduction in carbon emissions caused by the home’s electricity usage.
(The 3 percent figure could also be calculated directly by dividing 337 kWh per year of solar production by 10,500 kWh per year to run the home. For bigger or smaller arrays, just prorate your assumed wattage by my 220W; for 440W, say, double my figures.)
Balcony Solar metrics
Why write about balcony solar if it’s so inconsequential? CTC’s mission includes puncturing would-be climate balloons before they ascend too far. In the same vein, we practice quantification to make clear what does and doesn’t move the climate needle. (More on that further below.)
The best way to depict balcony solar’s climate value is to express it in terms of tangible metrics. We’ve selected two. Both assume the basic, lower-end PV array I assumed at the top: a 3.5 foot-square array whose peak output is 220 watts.
1. It would take 50 million 220W balcony solar units (bsu’s) to restore the climate benefit we destroyed in 2020-2021 when we shut the high-performing Indian Point nuclear power plant 32 miles from Midtown Manhattan.
2. A single person cutting back their driving by a mile a day would provide the same climate benefit over the course of a year as a single 220W bsu.
(Calculations in sidebar. Now you know why we led with images of an urban dweller as cyclist and balcony solar user.)
Yes, it’s dense — as befits a sidebar. The numbers tell a story. Follow the color co-ordination.
Ponder that: It would take fifty million smallish bsu’s to level up to the fossil fuel carbon emissions that Indian Point was keeping at bay by supplying the New York City area year in and year out with abundant carbon-free power. Deploying that many balcony solar units would entail 10 bsu’s for each of the 5 million households in the MTA’s service territory. (The Metropolitan Transportation Authority provides subway, bus and commuter rail transit in the five boroughs and seven suburban counties.) Or, if those same households upgraded to 1100-watt bsu’s, collectively they would still make up only half of the lost Indian Point power.
The second comparison, involving driving, is perhaps trickier to grasp but more interesting, since it relates to people’s behavior. Living differently isn’t part of public discourse, at least not in the USA, and especially when what’s being served up is using less. But “reducing,” as we might call it (remember “Reduce, Reuse, Recycle”? or, “Insulate, then Insolate”?) is just as potent for cutting emissions as switching to renewables — even more so when the reducing means driving less, considering the multitude of benefits that accrue from diminishing cars’ imprints on our communities. Still, staying on topic: driving just one fewer mile per day brings about the same shrinkage in carbon emissions as deploying one 220W solar array.
What Balcony Solar boosters are really saying
To be fair, our friends at Inside Climate News and, yes, The New York Times appear to be trying to modulate their balcony solar enthusiasm.
ICN‘s Dan Gearino, whom we cited up front, said he looked to Germany, the birthplace of balcony solar, to see if the units made sense for U.S. households. His takeaway: “It may make more sense financially to spend the cost of plug-in solar on insulation, air sealing or other basic measures to reduce energy use.” Hooray: insulate before you insolate.
Gearino helpfully interviewed renewables guru (and U.S. emigré) Craig Morris, who currently heads Germany’s plug-in solar trade association, Bundesverband Steckersolar. To Morris, balcony solar’s main advantages are that it provides power without taking up land, and that it affords people a way to “become participants in the transition to clean energy.” Behold, guerrilla solar. That, in turn, bolsters “the political consensus that supports the transition.” But Morris also made clear that widespread adoption of plug-in solar would only meet “about 2 percent of Germany’s electricity demand.”
Morris’s “about 2 percent” feels right for Germany. But not for the U.S., where widespread adoption of virtually any individual carbon alternative seems forever out of reach, and where the energy pie is so much larger — think giant fridges, freezers for beer, steroidal homes bursting with piles of powered toys, not to mention industrial and institutional electricity use that Morris correctly excluded from his figure.
Don’t forget to micro-dose. NYT headline + image for David Wallace-Wells’ guest essay (see text). Image by Rui Pu.
Both Gearino and Morris seem more measured than climate journalist Robinson Meyer, founding editor of Heatmap and frequent contributor to The Times, where he wrote about balcony solar in mid-June.
“New zero-carbon power kits will allow Americans to make their own energy choices,” declares the callout to the print version of Meyer’s NYT guest essay, The Tiny Solar Panel That Could Change America. (The even more expansive print headline invites us to “Forget Roofs. Backyard Solar Is the Next Frontier.”)
Wallace-Wells is of two minds. He calls balcony solar “a small way that apartment- and condo-dwelling Americans can take ownership of their energy choices and cut down their pollution on the margins.” No quarrel there, thanks to his qualifiers “small” and “on the margins.” Earlier, though, he opines that balcony solar units “have the potential to change how Americans understand and consume energy,” But read further and you’ll again see Wallace-Wells cautioning that “Balcony solar will play one small role in [the] drama” of transiting to the new world of clean, abundant energy.
Any such caveats are welcome these days, amid widespread solar hoopla. Still, it doesn’t seem to be in Wallace-Wells’ toolkit — or that of Inside Climate News and other mainstream climate journalists — to tutor their audiences as to the true limits of balcony solar and other panaceas. Just like it wasn’t in their field of vision a decade ago to lay out the true stakes of shutting Indian Point as Riverkeeper was singing its siren song.
What’s Next for NY Balcony Solar
Meantime, as Canary Media reported recently (and helpfully), New Yorkers concerned with climate and affordability are waiting for NY Gov. Kathy Hochul to sign the recently passed SUNNY (Solar Up Now New York) Act legalizing balcony and other plug-in solar. It would be head-spinning (and politically suicidal) if she didn’t, given near-universal support ranging from Con Edison to DSA Assembly Member Emily Gallagher, who told Canary Media, “This is the most popular bill I’ve [ever] worked on.”
My guess is that Hochul is waiting for the right moment, and perhaps the right “package,” that can advance and not undercut her push to launch five large new nuclear power plants around the state — one to be built by the public New York Power Authority, the others to be constructed and operated privately. A little bit of math, a la what we offered here a la Indian Point, might help her out.
The governor also must manage the veritable hot potato of her deferred implementation of the landmark 2019 Community Leadership and Climate Protection Act. She might do well to consider jettisoning the act’s unwieldy cap-and-invest centerpiece in favor of a straight-up carbon tax (with the revenues distributed pro rata to the state’s households) in its place. That, far more than balcony (or guerrilla) solar, could blow open the door to the “innovations and technologies we cannot yet imagine” that Wallace-Wells fantasized about in his Times essay.
On 11 June 2026, the Science Based Targets initiative (SBTi) published the most substantial revision of its flagship corporate framework since its introduction. The SBTi Corporate Net-Zero Standard Version 2.0 takes effect on 1 February 2027 and reshapes the way companies approach their net-zero targets.
