CCS Projects Reserve Account Contribution Tool

The Tool for Carbon Capture and Storage Projects Reserve Account Contribution Determination (CCS Reserve Account Contribution Tool, or Tool) provides an assessment framework for greenhouse gas (GHG) projects utilizing the Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas Emissions Reductions from Carbon Capture and Storage Projects (CCS Methodology) to determine the Reserve Account Contribution, which is the proportion of credits deposited at each issuance into the ACR Reserve Account to mitigate the risk of reversals. 

This Tool and the ACR Reserve Account Terms and Conditions operate in conjunction with the legally binding ACR CCS Project Reversal Risk Mitigation Contract between ACR and Project Proponents. The Reversal Risk Mitigation Contract details the requirements for reporting and compensating for Reversals.
