Mindy Hernandez is director of the Living Lab for Equitable Climate Action at the World Resources Institute.
We’ve all heard it: Eat less beef. Fly less. Buy secondhand. Track your carbon footprint.
But what’s less known is that the very idea of a ‘personal carbon footprint’ was popularized by oil giant BP, which, in a 2004 campaign, encouraged people to measure their own emissions – diverting attention from the fossil fuel industry and toward individual consumers.
Two decades later, that sleight of hand still shapes much of the public discourse, overshadowing the policies, infrastructure, and market leadership needed for faster, broader climate action.
New research from the World Resources Institute shows that adopting 11 pro-climate behaviors in energy, transport, and food could reduce an individual’s greenhouse gas emissions by about 6.53 tonnes per year, more than offsetting the average person’s current emissions (about 6.3 tonnes per year).
At energy security talks, US pushes gas and derides renewables
However, the study also reveals a stark gap between what’s theoretically possible and what’s achievable under current conditions. When efforts focus solely on changing individual behaviors – without transforming the overarching systems – they deliver only about one-tenth of their potential (about 0.63 tonnes annually), a fraction of the broad-based change the world truly needs.
The remaining 90% of emissions savings stay locked away, dependent on governments, businesses and collective action to make sustainable choices more accessible for all, not just the green-minded few.
How much do personal choices affect the climate?
The Intergovernmental Panel on Climate Change (IPCC) says comprehensive shifts in human behavior could theoretically reduce global emissions by up to 70% by 2050 – essentially wiping out emissions from China, the US, India, the EU, and Russia combined.
But it is also clear that these massive reductions would result from individual behavior change combined with supporting policy, industry and technological transformations.
Xi commits China to full climate plan but emissions-cutting ambition still unclear
This doesn’t mean individual action doesn’t matter. It means we need to focus on the systems that shape what’s possible for everyone in order to exponentially increase the potential impact.
While choices like flying less or switching to EVs make a difference, they only scale when supported by policies and infrastructure that make them easier, more affordable and accessible – which is where public and private-sector decisions play a crucial role.
Which behavior shifts make the biggest difference?
Our research also identifies which individual actions have the greatest climate impact – and therefore should be prioritized in decision-making. In order of climate impact, they are:
1) Shift to sustainable ground travel
Shifting from gas cars to public or active transit dramatically reduces emissions. Going car-free is 78 times more impactful than composting. Ditching your car may seem extreme, but even switching to a hybrid or electric car can have a significant impact.
2) Shift to air travel alternatives
When possible, replace flying with videoconferencing, train travel or even driving (ideally electric or hybrid). Air travel is among the most carbon-intensive activities. Since 89% of the world’s population has never flown, frequent flyers, especially in high-income groups, have a greater responsibility to lead on this.
3) Install residential solar and increase home energy efficiency
Rooftop solar and upgrades like better insulation, heat pumps or moving to a smaller house can significantly cut emissions. Unlike small changes (like switching light bulbs), these structural home improvements have a deeper impact – but often require government support, such as tax credits or incentives, to be widely accessible.
4) Eat more plant-rich meals
Cutting back on meat and dairy, particularly beef and lamb, has a massive, underestimated climate impact. While buying organic or local and reducing processed foods helps, shifting away from animal proteins matters far more. Full veganism can save nearly 1 ton of CO2 annually, but even reducing meat consumption achieves 40% of that.
How to change behaviors most effectively
These behaviors are only feasible at scale when systems support them. For example, Bogotá’s long-term investment in bike infrastructure helped increase cycling from less than 1% of trips in 1996 to 9% in 2017.
In the Netherlands, subsidies and net-metering for solar panels made renewable energy accessible, turning the country into a European leader in rooftop solar adoption. On the dietary front, public institutions and businesses can make plant-rich options more appealing and accessible (such as by adopting “meatless Monday,” like the Los Angeles Unified School District did in 2012).
How behavior change interventions are designed also matters. WRI reviewed numerous real-world programs and found that “choice architecture” (e.g. making sustainable options more visible or the default) and commitment devices (like pledges) are the most effective tools. Traditional information campaigns – like carbon calculators – are among the least.
System change is our only way out of the climate and biodiversity crises
Leveraging our collective power
The personal carbon footprint narrative has dominated the climate conversation for two decades, but it’s time to update it.
While personal choices do matter, this narrative has obscured where individuals’ real power lies: in voting, advocating for systemic change and pushing for the policies, infrastructure, and supportive environments that maximize the impact of individual climate action so it can be truly transformative.
To meet this moment, we must stop treating behavior change as a distraction from systems change – and start treating it as a force multiplier.

DeBriefed 27 February 2026: Trump’s fossil-fuel talk | Modi-Lula rare-earth pact | Is there a UK ‘greenlash’?
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Absolute State of the Union
‘DRILL, BABY’: US president Donald Trump “doubled down on his ‘drill, baby, drill’ agenda” in his State of the Union (SOTU) address, said the Los Angeles Times. He “tout[ed] his support of the fossil-fuel industry and renew[ed] his focus on electricity affordability”, reported the Financial Times. Trump also attacked the “green new scam”, noted Carbon Brief’s SOTU tracker.
COAL REPRIEVE: Earlier in the week, the Trump administration had watered down limits on mercury pollution from coal-fired power plants, reported the Financial Times. It remains “unclear” if this will be enough to prevent the decline of coal power, said Bloomberg, in the face of lower-cost gas and renewables. Reuters noted that US coal plants are “ageing”.
OIL STAY: The US Supreme Court agreed to hear arguments brought by the oil industry in a “major lawsuit”, reported the New York Times. The newspaper said the firms are attempting to head off dozens of other lawsuits at state level, relating to their role in global warming.
SHIP-SHILLING: The Trump administration is working to “kill” a global carbon levy on shipping “permanently”, reported Politico, after succeeding in delaying the measure late last year. The Guardian said US “bullying” could be “paying off”, after Panama signalled it was reversing its support for the levy in a proposal submitted to the UN shipping body.
Around the world
- RARE EARTHS: The governments of Brazil and India signed a deal on rare earths, said the Times of India, as well as agreeing to collaborate on renewable energy.
- HEAT ROLLBACK: German homes will be allowed to continue installing gas and oil heating, under watered-down government plans covered by Clean Energy Wire.
- BRAZIL FLOODS: At least 53 people died in floods in the state of Minas Gerais, after some areas saw 170mm of rain in a few hours, reported CNN Brasil.
- ITALY’S ATTACK: Italy is calling for the EU to “suspend” its emissions trading system (ETS) ahead of a review later this year, said Politico.
- COOKSTOVE CREDITS: The first-ever carbon credits under the Paris Agreement have been issued to a cookstove project in Myanmar, said Climate Home News.
- SAUDI SOLAR: Turkey has signed a “major” solar deal that will see Saudi firm ACWA building 2 gigawatts in the country, according to Agence France-Presse.
$467 billion
The profits made by five major oil firms since prices spiked following Russia’s invasion of Ukraine four years ago, according to a report by Global Witness covered by BusinessGreen.

Captured
The constituency of Richard Tice MP, the climate-sceptic deputy leader of Reform UK, is the second-largest recipient of flood defence spending in England, according to new Carbon Brief analysis. Overall, the funding is disproportionately targeted at coastal and urban areas, many of which have Conservative or Liberal Democrat MPs.
Spotlight
Is there really a UK ‘greenlash’?
This week, after a historic Green Party byelection win, Carbon Brief looks at whether there really is a “greenlash” against climate policy in the UK.
Over the past year, the UK’s political consensus on climate change has been shattered.
Yet despite a sharp turn against climate action among right-wing politicians and right-leaning media outlets, UK public support for climate action remains strong.
Prof Federica Genovese, who studies climate politics at the University of Oxford, told Carbon Brief:
“The current ‘war’ on green policy is mostly driven by media and political elites, not by the public.”
Indeed, there is still a greater than two-to-one majority among the UK public in favour of the country’s legally binding target to reach net-zero emissions by 2050, as shown below.
Steve Akehurst, director of public-opinion research initiative Persuasion UK, also noted the growing divide between the public and “elites”. He told Carbon Brief:
“The biggest movement is, without doubt, in media and elite opinion. There is a bit more polarisation and opposition [to climate action] among voters, but it’s typically no more than 20-25% and mostly confined within core Reform voters.”
Conservative gear shift
For decades, the UK had enjoyed strong, cross-party political support for climate action.
Lord Deben, the Conservative peer and former chair of the Climate Change Committee, told Carbon Brief that the UK’s landmark 2008 Climate Change Act had been born of this cross-party consensus, saying “all parties supported it”.
Since their landslide loss at the 2024 election, however, the Conservatives have turned against the UK’s target of net-zero emissions by 2050, which they legislated for in 2019.
Curiously, while opposition to net-zero has surged among Conservative MPs, there is majority support for the target among those that plan to vote for the party, as shown below.
Dr Adam Corner, advisor to the Climate Barometer initiative that tracks public opinion on climate change, told Carbon Brief that those who currently plan to vote Reform are the only segment who “tend to be more opposed to net-zero goals”. He said:
“Despite the rise in hostile media coverage and the collapse of the political consensus, we find that public support for the net-zero by 2050 target is plateauing – not plummeting.”
Reform, which rejects the scientific evidence on global warming and campaigns against net-zero, has been leading the polls for a year. (However, it was comfortably beaten by the Greens in yesterday’s Gorton and Denton byelection.)
Corner acknowledged that “some of the anti-net zero noise…[is] showing up in our data”, adding:
“We see rising concerns about the near-term costs of policies and an uptick in people [falsely] attributing high energy bills to climate initiatives.”
But Akehurst said that, rather than a big fall in public support, there had been a drop in the “salience” of climate action:
“So many other issues [are] competing for their attention.”
UK newspapers published more editorials opposing climate action than supporting it for the first time on record in 2025, according to Carbon Brief analysis.
Global ‘greenlash’?
All of this sits against a challenging global backdrop, in which US president Donald Trump has been repeating climate-sceptic talking points and rolling back related policy.
At the same time, prominent figures have been calling for a change in climate strategy, sold variously as a “reset”, a “pivot”, as “realism”, or as “pragmatism”.
Genovese said that “far-right leaders have succeeded in the past 10 years in capturing net-zero as a poster child of things they are ‘fighting against’”.
She added that “much of this is fodder for conservative media and this whole ecosystem is essentially driving what we call the ‘greenlash’”.
Corner said the “disconnect” between elite views and the wider public “can create problems” – for example, “MPs consistently underestimate support for renewables”. He added:
“There is clearly a risk that the public starts to disengage too, if not enough positive voices are countering the negative ones.”
Watch, read, listen
TRUMP’S ‘PETROSTATE’: The US is becoming a “petrostate” that will be “sicker and poorer”, wrote Financial Times associate editor Rana Forohaar.
RHETORIC VS REALITY: Despite a “political mood [that] has darkened”, there is “more green stuff being installed than ever”, said New York Times columnist David Wallace-Wells.

Seven Pacific island nations say they will demand heftier levies on global shipping emissions if opponents of a green deal for the industry succeed in reopening negotiations on the stalled accord.
The United States and Saudi Arabia persuaded countries not to grant final approval to the International Maritime Organization’s Net-Zero Framework (NZF) in October and they are now leading a drive for changes to the deal.
In a joint submission seen by Climate Home News, the seven climate-vulnerable Pacific countries said the framework was already a “fragile compromise”, and vowed to push for a universal levy on all ship emissions, as well as higher fees . The deal currently stipulates that fees will be charged when a vessel’s emissions exceed a certain level.
“For many countries, the NZF represents the absolute limit of what they can accept,” said the unpublished submission by Fiji, Kiribati, Vanuatu, Nauru, Palau, Tuvalu and the Solomon Islands.
The countries said a universal levy and higher charges on shipping would raise more funds to enable a “just and equitable transition leaving no country behind”. They added, however, that “despite its many shortcomings”, the framework should be adopted later this year.
US allies want exemption for ‘transition fuels’
The previous attempt to adopt the framework failed after governments narrowly voted to postpone it by a year. Ahead of the vote, the US threatened governments and their officials with sanctions, tariffs and visa restrictions – and President Donald Trump called the framework a “Green New Scam Tax on Shipping”.
Since then, Liberia – an African nation with a major low-tax shipping registry headquartered in the US state of Virginia – has proposed a new measure under which, rather than staying fixed under the NZF, ships’ emissions intensity targets change depending on “demonstrated uptake” of both “low-carbon and zero-carbon fuels”.
The proposal places stringent conditions on what fuels are taken into consideration when setting these targets, stressing that the low- and zero-carbon fuels should be “scalable”, not cost more than 15% more than standard marine fuels and should be available at “sufficient ports worldwide”.
This proposal would not “penalise transitional fuels” like natural gas and biofuels, they said. In the last decade, the US has built a host of large liquefied natural gas (LNG) export terminals, which the Trump administration is lobbying other countries to purchase from.
The draft motion, seen by Climate Home News, was co-sponsored by US ally Argentina and also by Panama, a shipping hub whose canal the US has threatened to annex. Both countries voted with the US to postpone the last vote on adopting the framework.

IMO head: Shipping decarbonisation “has started” despite green deal delay
Arsenio Dominguez said the shipping industry’s net zero emissions goal is not in dispute although countries have stalled on adopting a framework to reach it -
US-led alliance wins a year’s delay in adoption of green shipping deal
The IMO’s Net-Zero Framework will be up for approval again in October 2026, after the US and Saudi Arabia persuaded countries not to vote on it as planned
The IMO’s Panamanian head Arsenio Dominguez told reporters in January that changes to the framework were now possible.
“It is clear from what happened last year that we need to look into the concerns that have been expressed [and] … make sure that they are somehow addressed within the framework,” he said.
Patchwork of levies
While the European Union pushed firmly for the framework’s adoption, two of its shipping-reliant member states – Greece and Cyprus – abstained in October’s vote.
After a meeting between the Greek shipping minister and Saudi Arabia’s energy minister in January, Greece said a “common position” united Greece, Saudi Arabia and the US on the framework.
If the NZF or a similar instrument is not adopted, the IMO has warned that there will be a patchwork of differing regional levies on pollution – like the EU’s emissions trading system for ships visiting its ports – which will be complicated and expensive to comply with.
This would mean that only countries with their own levies and with lots of ships visiting their ports would raise funds, making it harder for other nations to fund green investments in their ports, seafarers and shipping companies. In contrast, under the NZF, revenues would be disbursed by the IMO to all nations based on set criteria.
Anais Rios, shipping policy officer from green campaign group Seas At Risk, told Climate Home News the proposal by the Pacific nations for a levy on all shipping emissions – not just those above a certain threshold – was “the most credible way to meet the IMO’s climate goals”.
“With geopolitics reframing climate policy, asking the IMO to reopen the discussion on the universal levy is the only way to decarbonise shipping whilst bringing revenue to manage impacts fairly,” Rios said.
“It is […] far stronger than the Net-Zero Framework that is currently on offer.”

Doubts over whether governments will maintain ambitious targets on boosting the use of sustainable aviation fuel (SAF) are a threat to the industry’s growth and play into the hands of fossil fuel companies, investors warned this week.
Several executives from airlines and oil firms have forecast recently that SAF requirements in the European Union, United Kingdom and elsewhere will be eased or scrapped altogether, potentially upending the aviation industry’s main policy to shrink air travel’s growing carbon footprint.
Such speculation poses a “fundamental threat” to the SAF industry, which mainly produces an alternative to traditional kerosene jet fuel using organic feedstocks such as used cooking oil (UCO), Thomas Engelmann, head of energy transition at German investment manager KGAL, told the Sustainable Aviation Fuel Investor conference in London.
He said fossil fuel firms would be the only winners from questions about compulsory SAF blending requirements.
The EU and the UK introduced the world’s first SAF mandates in January 2025, requiring fuel suppliers to blend at least 2% SAF with fossil fuel kerosene. The blending requirement will gradually increase to reach 32% in the EU and 22% in the UK by 2040.
Another case of diluted green rules?
Speaking at the World Economic Forum in Davos in January, CEO of French oil and gas company TotalEnergies Patrick Pouyanné said he would bet “that what happened to the car regulation will happen to the SAF regulation in Europe”.
The EU watered down green rules for car-makers in March 2025 after lobbying from car companies, Germany and Italy.
“You will see. Today all the airline companies are fighting [against the EU’s 2030 SAF target of 6%],” Pouyanne said, even though it’s “easy to reach to be honest”.
While most European airline lobbies publicly support the mandates, Ryanair Group CEO Michael O’Leary said last year that the SAF is “nonsense” and is “gradually dying a death, which is what it deserves to do”.
EU and UK stand by SAF targets
But the EU and the British government have disputed that. EU transport commissioner Apostolos Tzitzikostas said in November that the EU’s targets are “stable”, warning that “investment decisions and construction must start by 2027, or we will miss the 2030 targets”.
UK aviation minister Keir Mather told this week’s investor event that meeting the country’s SAF blending requirement of 10% by 2030 was “ambitious but, with the right investment, the right innovation and the right outlook, it is absolutely within our reach”.
“We need to go further and we need to go faster,” Mather said.
SAF investors and developers said such certainty on SAF mandates from policymakers was key to drawing the necessary investment to ramp up production of the greener fuel, which needs to scale up in order to bring down high production costs. Currently, SAF is between two and seven times more expensive than traditional jet fuel.
Urbano Perez, global clean molecules lead at Spanish bank Santander, said banks will not invest if there is a perceived regulatory risk.
David Scott, chair of Australian SAF producer Jet Zero Australia, said developing SAF was already challenging due to the risks of “pretty new” technology requiring high capital expenditure.
“That’s a scary model with a volatile political environment, so mandate questioning creates this problem on steroids”, Scott said.
Others played down the risk. Glenn Morgan, partner at investment and advisory firm SkiesFifty, said “policy is always a risk”, adding that traditional oil-based jet fuel could also lose subsidies.
Asian countries join SAF mandate adopters
In Asia, Singapore, South Korea, Thailand and Japan have recently adopted SAF mandates, and Matti Lievonen, CEO of Asia-based SAF producer EcoCeres, predicted that China, Indonesia and Hong Kong would follow suit.
David Fisken, investment director at the Australian Trade and Investment Commission, said the Australian government, which does not have a mandate, was watching to see how the EU and UK’s requirements played out.
The US does not have a SAF mandate and under President Donald Trump the government has slashed tax credits available for SAF producers from $1.75 a gallon to $1.
Is the world’s big idea for greener air travel a flight of fancy?
SAF and energy security
SAF’s potential role in boosting energy security was a major theme of this week’s discussions as geopolitical tensions push the issue to the fore.
Marcella Franchi, chief commercial officer for SAF at France’s Haffner Energy, said the Canadian government, which has “very unsettling neighbours at the moment”, was looking to produce SAF to protect its energy security, especially as it has ample supplies of biomass to use as potential feedstock.
Similarly, German weapons manufacturer Rheinmetall said last year it was working on plans that would enable European armed forces to produce their own synthetic, carbon-neutral fuel “locally and independently of global fossil fuel supply chain”.
Scott said Australia needs SAF to improve its fuel security, as it imports almost 99% of its liquid fuels.
He added that support for Australian SAF production is bipartisan, in part because it appeals to those more concerned about energy security than tackling climate change.
