ProviderRegionKey = `$\{string\}:$\{string\}`

Defined in: adapters/src/carbon.ts:22

Carbon-aware routing data. Estimated grid CO2 intensity (gCO2eq per 1k tokens) per provider+region. Numbers are best-effort approximations derived from public grid-mix data and provider PUE disclosures — they are good enough to differentiate "very dirty" from "very clean" but are not audited.

Sources:

• Electricity Maps (electricitymaps.com) for grid carbon intensity.
• Provider PUE / efficiency reports (Anthropic, Google, AWS).
• LLMCarbon (Faiz et al., 2024) for tok→J coefficients.

Pull-requests welcome to refine. The table is community-updateable and ships at compile time; a runtime table can be passed via applyCarbonTable(candidates, customTable).

Closes part of issue #209.
