• A new study maps areas designated for potential carbon dioxide removal projects, such as planting forests or bioenergy crops, that might conflict with biodiversity hotspots.

• Such climate strategies could harm species if they change existing ecosystems or use too much land.

• The study points to the importance of more careful site selection for these projects.

• The authors of the study also note the importance of reducing humanity’s CO2 emissions, rather than relying solely on removing CO2 from the atmosphere later on.
