Carbon offsetting

When a person, company or country offsets their emissions, this means that they compensate for part of their carbon footprint by paying someone else, outside their own value chains, for the emissions reductions they claim to have achieved. They usually do this by purchasing carbon credits, each of which is supposed to represent a tonne of carbon dioxide or its equivalent in other greenhouse gases (CO2e).

Companies around the world have labelled their activities as carbon or climate neutral, have set net-zero emissions targets or have otherwise sought to green their image by buying carbon credits from climate projects and using them to offset their emissions. 

This is an extremely problematic practice. At a time when the science shows that the emissions of advanced economies like the EU need to fall by 65% by 2030, offsetting does nothing to reduce the actual internal emissions of the offsetter, it simply shifts the problem onto someone else’s shoulders.

Moreover, the climate impact of projects financed through the sale of carbon credits is unclear. At best, they do not represent an actual tonne of emissions. At worst, their climate impact is grossly exaggerated. 

What is CMW doing about it?

When it comes to carbon offsetting, Carbon Market Watch focuses on:

  • Monitoring the use of carbon credits used for offseting by companies, countries and individuals
  • Investigating the quality of projects and the carbon credits they issue
  • Scrutinising the work of standards bodies, intermediaries and ratings agencies
  • Advocating for a ban on claims based on offsetting in order to indirectly regulate the voluntary carbon market

“Offsetting emissions is not the solution – it is an illusion. The only way to truly help the climate is by slashing emissions.”

What changes is CMW demanding?

Countries and corporations prioritise deep, rapid and sustained emissions reductions 

Companies stop offsetting their emissions 

Standards and intermediaries stop selling carbon credits as offsetting tools

Buyers of carbon credits find more sustainable uses for carbon credits, such as the ‘contribution model’ in which buyers simply state that they contributed to climate action via funding a certain type of project(s)



2030 climate targets of over 50 top corporations significantly off track to keep within 1.5°C limit

At a time when global carbon emissions need to be almost halved by 2030, 51 major corporations’ climate commitments amount only to reducing their median carbon footprint by as little as 30%, reveals the 2024 Corporate Climate Responsibility Monitor. Tighter regulations from governments are needed to raise the bar, both for companies which are taking insufficient action, and those who are not doing anything at all.

After years of campaigning by activists, the tide is finally turning on the idea of companies buying carbon credits to compensate for their emissions. But how exactly is carbon offsetting harmful and what’s the alternative?

Corporations assessed in the 2023 Corporate Climate Responsibility Monitor plan to offset up to 45% of their combined carbon footprint
