Show HN: I made an API to calculate the C02e footprint of credit card purchases

Happy Earth Day HNers,

I built carbon ledger to make it easy for companies to build climate-conscious applications using their payments data. There's currently an explosion in fintech, climate-tech and SaaS companies who are adding climate features to their apps and Carbon Ledger will power these: Carbon neutral credit cards, Automated Scope 3 emissions calculations, Subscription offset programs and Other planet-friendly ideas!

My goal with Carbon Ledger is to make it easy to launch these features so they can drive behaviour change and educate consumers about climate change. Carbon Ledger brings a developer-friendly API and research-backed methodology to market so teams can focus on their users!
