Dear CARB Staff, In the new CA-GREET4.0 calculators, just like in CA-GREET3.0, you have the same 3.66 and 3.75 CI g CO2e/MJ for tailpipe emissions (CH4 and N2O and other GHG's) for biomethane/RNG pathways on landfill, wastewater pathways. Previously on page 18 & 22, you have the CI-stackup for fossil NG pathways, on page 22 that breakout the tailpipe emissions for CO2, CH4 and N2O. Can you make it so that the new technical manual shows if the calculator is to have 3.66 or 3.75 CI, how much CI/biogenic CO2 is also in the tailpipe CI stackup? This would help the question on how much impact there is from tailpipe emissions reporting. https://ww2.arb.ca.gov/sites/default/files/classic/fuels/lcfs/ca-greet/lut-doc.pdf |
