'Worthless' forest carbon offsets risk exacerbating climate change
In early 2023, the Guardian published an article suggesting that more than 90% of rainforest carbon offsets are worthless.

- These credits are essentially a promise to protect forests and can be bought as a way to “offset” emissions elsewhere.
- They quantify the carbon saved through reducing deforestation relative to what would have happened without the project, and sell these emission reductions as credits.
- The finding that many REDD+ carbon credits have not delivered forest conservation is extremely worrying to anyone who cares about the future of tropical forests.
Deforestation could simply move elsewhere
- Carbon credits also face other challenges, one of the biggest being “leakage” or displacement of deforestation.
- Leakage may occur because the people who were cutting down the forest simply relocate to a different area.
- Alternatively, demand for food or timber that was fuelling deforestation in one place may be met by deforestation elsewhere – perhaps on the other side of the world.
- Another problem is ensuring that the forests are protected in perpetuity so that reduced deforestation represents permanent removal of carbon from the atmosphere.
Reasons to be cautious
- Even if these problems can be solved, there are still reasons to be cautious about the role of carbon offsets in combating climate change.
- Second, keeping warming within 2°C will require most deforestation to be stopped and major reductions in fossil fuel emissions.
- If you want to contribute to tackling climate change, perhaps the only real option is to not take the flight.
