What is a verified tonne worth across markets?

Where independently verified avoided-emission claims from renewable generation transact today, primarily bilateral/OTC. Realized prices depend on vintage, registry, project type, and counterparty.

Brazil's compliance market (SBCE, Lei 15.042/2024) contemplates accredited crediting methodologies (CRVE). Karbera's methodology is built for this bar — fully published, no self-reporting, hourly ONS-verified data — and accreditation under the SBCE managing body is a stated Karbera objective as the system's rules are finalized. Brazil is also accelerating Paris Agreement Crediting Mechanism (PACM / Article 6) adoption; internationally transferred mitigation outcomes require exactly the provenance and no-double-counting guarantees Karbera's audit architecture provides.

What the world's compliance markets pay for a tonne. These systems settle in their own allowances or narrow domestic offset protocols; renewable-displacement credits are not eligible. Shown as reference anchors for what verified carbon is worth where verification is mandatory — not as an available market.

Hyperscalers are moving from annual renewable matching to 24/7 hourly carbon-free energy commitments, with granular-certificate standards (EnergyTag) formalizing per-hour attributes. The procurement frontier is emissions-matched: buying the hours that displace the most carbon. Karbera measures precisely that quantity — hourly, per-plant, provenance-attached — and the marginal emission factor (MEF) on our methodology roadmap is the exact signal emissions-first procurement ranks on. No established price benchmark exists yet for granular attributes; this lane shows demand direction, not price.
