Climate economist here: great and brave idea. Just to mention, emissions data from blogs can only be too sloppy. What data is the most difficult to find in particular? Happy to think and help.
Hi! Ya we only use full GHGP inventory data. Honestly, the hardest data to gather is clean transaction data! The Brex API returns relatively clean data. Other banks and financial institutions, via Plaid, often have pretty messy merchant and category info. If I had a magic wand, it's actually the spend data I'd focus on — super clean, itemized transaction data would be amazing.
