Alternatively known as greenhouse gas removal (GGR), carbon dioxide removal (CDR), or negative emissions technology (NET), the concept of removing greenhouse gases (GHGs)—primarily CO2—from the atmosphere has been gaining increasing academic, industrial, financial, and political attention over recent years as corporate and national commitments to net-zero targets proliferate. Practically all pathways to net zero include essential contributions from NET, typically 10%–20% of current national emissions. However, concerns regarding its role to meet climate targets persist. We set out a frame-work to transition to credible GHG removal. Without a rigorous effort to increase the credibility of CDR pathways via effective Monitoring, Reporting and Verification, there is a very real possibility that although there will be many projects, ultimately the market will never scale up.
