It can be pretty down in the weeds to calculate the emissions from these projects and since it varies by type I can't summarize it all here. However if you have more specific questions I'd be happy to answer.
Re: carbon footprints, it's a little simpler. We use data + research from Berkeley's cool climate lab (https://coolclimate.berkeley.edu/publications) The main model is maintained by them, and is based on linear regression from a bunch of lifestyle variables that you input into the calculator. Our version is slightly different because we base it on country instead of zip code, so we scale most input variables by the country's per capita emissions to get a good estimate.
