An example NY dairy AD-to-RNG project CI score is computed using the CA LCFS Tier 1 CI Calculator and six different project scenarios are compared, including options to use part of the AD biogas for digester heating and to cover the digested effluent long-term storage. While the CI score under the CA LCFS program uses a 100-year global warming potential (GWP) for GHGs, a comparison of the total GHG reduction of the example project using the NY-adopted 20-year GWP is given in the summary.en-USbiomethaneanaerobic digestiondairy manurefuel standardgreenhouse gasreport
