Yes. There are interactions but, as you said, when regulations are proposed, they include an estimate of how many megatonnes of greenhouse gas emissions they will avert. We should try to do that as we implement the regulations, so that we can make the necessary changes and keep from falling short again on the 2030 target.
It's possible to make that estimate when the regulations are proposed. I know it's a challenge because there are interactions, but it's better than doing nothing and wondering why we haven't met our greenhouse gas reduction target in 2030.
