Study: Carbon offsets aren’t doing their job, overstate impact

This information is intended to later be used to calculate the forest carbon content. Indigenous people have contributed less to climate change than has any other section of the population, yet they are among those most in jeopardy from its impact.

Carbon offset projects claiming to curb deforestation are significantly overestimating their impact, according to a new study published in Science on Thursday.
Sold as a way to lessen the impact of greenhouse gas emissions by allowing polluters or consumers to purchase offsets or credits that allow them to keep emitting in return for funding projects that decrease emissions elsewhere, offsets have become a high-profile model for corporate climate action.
