Turn every transaction into climate action.
AREKA is carbon API infrastructure that plugs into financial systems. Every transaction's carbon footprint is measured instantly, and the climate contribution you assign is recorded publicly.
Micro Contributions · Big Impact
Everyday transactions grow into measurable, reportable environmental value.
How It Works
Five steps connect financial flow to verifiable environmental impact. Micro-contributions pool in one place; a share of carbon credits is assigned for the measured footprint, and the share is recorded on verifiable certificates.
Integrate and measure
Our API plugs into your financial stack with a quick, flexible setup. Every transaction streams in as data and is converted into a carbon footprint using sourced, versioned emission factors: the same input always gives the same result.
Aggregate
Micro-impacts pool into one place. Millions of small actions add up into a measurable, enterprise-scale impact.
Verify
Data is written onchain as a public record. Every impact carries an onchain proof.
Convert to value
A share of high-integrity carbon credits is assigned for the measured footprint. The records are kept on public digital infrastructure, and each customer gets a trackable, soulbound certificate for their part.
Business, academia and people aren't on the same page.
Business
No competitive edge, no presence in the customer experience, investments don't pay back.
Academia
Data is unreliable, processes are manual, impact isn't measured at the moment of action.
People
Unaware of their impact, not part of the process, doubting they can make a difference.
