The Science is Clear

Ambitious action is needed to reduce greenhouse gas (GHG) emissions while also rapidly scaling carbon dioxide removal (CDR). Effective and equitable climate action can both reduce climate loss and damage and provide wider benefits to society. The AR6 WIII report from the Intergovernmental Panel on Climate Change (IPCC) estimates the global community must remove 100-1,000 billion metric tonnes (Gt) of carbon dioxide (CO2) by 2100 to limit persistent warming to no more than 1.5°C. To reach this goal, large-scale CDR projects must annually remove 5-10 GtCO2 by midcentury. Achieving this goal will require rapid scale-up and deployment of all viable CDR methods.
