Choosing a high-impact carbon credit takes dilligence, time and care. But retiring one must be a seamless process with minimal friction. Every carbon retirement Klima Protocol settles on @Base goes through one contract. The "Retirement Aggregator". Developed in collaboration with @carbonmarkcom Nothing sits between a buyer and a retirement when they settle via the protocol. Execution terms come from protocol state and apply identically to everyone touching the contract at that moment. No intermediation. No price obfuscation. Near instant settlement. So far the Retirement Aggeragtor has processed: - 41,874 retirements. - 50,861 tCO₂e. - from 71 wallets. - with 211 named beneficiaries. Users can pay in base:0x00fbac94fec8d4089d3fe979f39454f48c71a65d or $USDC and let the contract source retirements for them, quoting the price first so they know what the retirement costs before they commit. Updated in real-time. Users include: a VC, a blockchain foundation, people retiring in their own names, an onchain bridge. The rest arrives through things built on top: Carbonmark's marketplace, our shared x402 endpoint, the @klimacarbonbot. To scale climate finance, we need to reduce intermediation and fees where it does not add value, and that is what the RA offers.

The Carbon Auto-Retirement Bot Every fifteen minutes, when it has funds, a bot on @Base retires carbon credits with whatever has been donated to it: 0xfB7eF581B0338A31e47AA9770345b26D46BF0451 Nobody approves the transactions. The schedule, the rotation through carbon classes, and the amount it spends are all fixed in code. It decides nothing. Each run calls @KlimaProtocol's x402 endpoint, takes the protocol's prevailing execution rate, and burns kVCM directly against a carbon class. The credit is retired on Base blockchain and a public certificate resolves on @Carbonmark. No intermediary, no discretionary fee at the protocol layer. The bot spends roughly a quarter of its budget on each of four Klima carbon classes: solar, wind, city forest credits, ocean alkalinity enhancement. Equal budget, not equal tonnage. Execution rates differ by class, so around 26,400 $kVCM has gone to ocean alkalinity enhancement and returned 0.525 tonnes, while around 32,700 $kVCM has gone to small-scale wind and returned 9,627 tonnes. Since April: 2,673 retirements, 20,404 tonnes of CO₂e, and 120,065 $kVCM burned. @KlimaCarbonBot

Carbon removal sounds abstract. At the Wakefield Biochar facility in Georgia, USA, it leaves in bags. Pine bark waste is pyrolysed into biochar that holds its carbon for at least a century under CORC100+, then sold as soil improver through outlets like Walmart, Lowe's and Amazon. 166 tCO2eq is available for retirement via the Klima Protocol: transparent pricing and immediate execution.

Klima’s incentive rates aren’t fixed, and nobody sets them. They respond to where participants stake, directing incentives toward the durations and market functions needing support. Since February, the peak has moved out by ~2 years.
