TRACEcdr is an interactive tool developed by the LSE's Grantham Research Institute and AlliedOffsets to improve transparency in the carbon dioxide removal (CDR) industry.

It was developed based on research conducted by Leo Mercer and Josh Burke in 2023. TRACEcdr data was also used in the MRV chapter in the second edition of the State of CDR report, of which Leo and Josh served as supporting and lead authors, respectively.
