Happy Earth Day HNers,<p>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!<p>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!
