ACR Announces Stakeholder Consultation for CCS Methodology v2.0

The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, has published for stakeholder consultation an updated version 2.0 of its Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas Emissions Reductions and Removals from Carbon Capture and Storage Projects.

As in the current published version of the methodology, greenhouse gas emission reductions and removals are quantified from the capture, transportation, and storage of anthropogenic CO2.  The new version of the methodology extends eligibility to projects that utilize Carbon Dioxide Removal (CDR) technologies such as Direct Air Capture (DAC) and the use of Sustainable Biomass as a feedstock.  The methodology also expands the eligibility criteria for geologic storage to include saline formations and depleted oil and gas reservoirs which will significantly expand the geographic range for supported projects.  For projects that utilize CO2 for Enhanced Oil Recovery, Version 2.0 includes calculations to account for emissions from transportation, refining, and end use of the produced hydrocarbons.
