Criteria
Carbon calculators vary significantly in terms of quality and coverage. The best ones are kept up to date with the research, consider local conditions in their assumptions, and are easy to use and understand.
Based on my research, I believe calculators powered by organizations like AMEE and ZeroFootprint do the best job with the first two criteria.
