New CCS Methodology Covers Direct Air Capture

American Carbon Registry (ACR), a major offset standards body, has released a draft CCS carbon offset methodology that explicitly covers EOR projects sourced by direct air capture (DAC) geoengineering.  This methodology, drafted by the Blue Strategies consulting group, defines CCS in terms inclusive of DAC: "Carbon capture and storage (CCS) is the separation and capture of carbon dioxide (CO2) from the atmospheric emissions of industrial processes or the direct air capture (DAC) of atmospheric CO2 and the transport and safe, permanent storage of the CO2 in deep underground geologic formations" (p. 1).  If the methodology is adopted, EOR projects using both DAC and conventional CO2 sources will be eligible for ACR offset credits tradable on the voluntary carbon market.  A public comment period extends through the end of January.

Note: ACR subsequently clarified that its proposed methodology applies only to CO2-EOR projects, and not to traditional CCS projects involving storage in saline aquifers.  The above post has been duly revised.
