I like to think of this question in terms of partitioning of the planet's carbon stock. Global carbon is divided into two reservoirs: the lithosphere (rocks and fossil fuels) and the biosphere (soil, biomass, oceans, atmosphere). While some climate disruption is presented by transfers within the

CDR reduces net emissions. What is the difference between a coal plant with CCS and a bio energy facility without CCS versus a coal plant without CCS and a bio energy facility with CCS? Why should the addition of CCS be considered mitigation in the first case but not in the second case? On Wed,

I agree with Dr Burns, the conflation of CDR with mitigation is problematic. It is both more logical and more politically expedient for CDR to be referred to as "restoration" or "remediation". -- Adam Dorr University of California Los Angeles School of Public Affairs Urban Planning PhD Candidate a
