Carbon Dioxide Removal

RMI Is Supporting an Essential New Field

To avoid catastrophic climate change, the IPCC has concluded that in addition to slashing emissions, we must remove more than a gigaton of carbon dioxide from our atmosphere by 2050. Carbon dioxide removal (CDR) refers to the removal of carbon dioxide from the air or the oceans while point-source carbon capture involves the capture of carbon emissions from fossil fuel plants and industry.

Governments, corporations, and philanthropists are exploring CDR’s potential as a long-term solution, and RMI is committing resources and expertise to better understand the CDR field and catalyze its development in a sustainable and equitable way, alongside continued decarbonization and mitigation efforts. We are doing this through an initiative dedicated to CDR, while our clean tech startup accelerator, Third Derivative (D3), is supporting new technology through the First Gigaton Captured cohort.

RMI is committed to advancing innovation, building the ecosystem for CDR, and managing its risks. Below, learn what RMI is “thinking” and “doing” on this emerging issue.
