As a result of this potential to help address climate change, mCDR has become a rapidly evolving field, spanning early-stage research, in-water field trials and, in some cases, early deployment. As interest grows across academia, industry, philanthropy, governments and civil society, so do questions around governance, environmental integrity, accountability, equity and public trust. How these questions are answered will meaningfully shape the direction of the field.…
