Every day, people are invited to buy products and services with supposed climate benefits – whether this be “carbon-neutral flights”, “net-zero beef” or “carbon-negative coffee”.
Such claims rely on “carbon offsets”.
Put simply, carbon offsets involve an entity that emits greenhouse gases into the atmosphere paying for another entity to pollute less.
For example, an airline in a developed country that wants to claim it is reducing its emissions can pay for a patch of rainforest to be protected in the Amazon. This – in theory – “cancels out” some of the airline’s pollution.
It is not just businesses that are relying on carbon offsets. Major economies, too, are investing in carbon offsets as a way to meet their international emissions targets – with offsetting becoming a major talking point at UN climate negotiations.
For its supporters, offsetting is a mutually beneficial system that funnels billions of dollars into emissions-cutting projects in developing countries, such as renewable energy projects or clean cooking initiatives.
But offsetting has also faced intense scrutiny from researchers, the media and – increasingly – law courts, with businesses facing accusations of “greenwashing” over their carbon-offsetting claims.
There is mounting evidence that offset projects, from clean-cooking initiatives to forest protection schemes, have been overstating their ability to cut emissions. One yet-to-be published study suggests that just 12% of offsets being sold result in “real emissions reductions”.
Projects have also been linked to Indigenous people being forced from their land and other human rights abuses.
Decades of countries trading carbon offsets has had a negligible impact on emissions and likely even increased them.
In this in-depth Q&A, Carbon Brief explains what offsets are, how they are being used by businesses and nations, and why they can be a problematic climate solution.
The article also explores whether a system, which one expert describes as “deeply broken”, could ever be effectively reformed.

Trump Administration Dropped Controversial Climate Report From Its Decision to Rescind EPA Endangerment Finding
The final EPA rule explicitly omitted the report commissioned last year to justify revoking the endangerment finding, citing “concerns raised by some commenters.”
When the U.S. Environmental Protection Agency rescinded its bedrock endangerment finding Thursday, it explicitly excluded a controversial report issued last year by the U.S. Department of Energy that argued the dangers of human-induced climate change were being overstated.
Tailpipe standards meant to hasten adoption of electric vehicles were slashed alongside the scientific basis for regulating greenhouse gas emissions. That will come at a cost.
With the repeal of the Environmental Protection Agency’s scientific finding on the dangers of greenhouse gases, the Trump administration is aiming to take out many federal actions on climate change in one blast.

A doubling of fish biomass along Asia’s longest river shows hope for large-scale conservation efforts and a lifeline for the endangered finless porpoise.
Flowing almost 4,000 miles from the Tibetan Plateau to the East China Sea, the Yangtze is China’s “Mother River.” From the emerald-green rice paddies of Hunan to the industrial hubs of Wuhan and Shanghai, the river basin generates 40 percent of the nation’s economic output. Yet, 70 years of rapid development had, until recently, wreaked havoc on its delicate marine ecosystem.
