Revenue per Carbon
The ratio of revenue generated to kilograms of CO2-equivalent emitted by the inference and supporting infrastructure that produced it, measured per period at the level of the whole business.
Revenue per Carbon denominates a business's output in the environmental unit regulators, acquirers, and institutional investors are converging on. Where a traditional business measured revenue per employee, and an agentic business can measure revenue per token, Revenue per Carbon captures value created per unit of environmental cost — regardless of which models, providers, or efficiency techniques sit underneath.
The metric exploits a structural property of the autonomous business: its operational footprint is overwhelmingly metered inference rather than estimated human activity. Token consumption is billed per agent and per provider, convertible to energy through published per-token figures and to CO2e through regional grid carbon intensity. This makes an autonomous business's footprint provable to the kilogram from metered data, at a granularity no workforce-based business can match — the claim is verifiability, not automatic greenness.
Revenue per Carbon is a business-level metric, distinct from engineering-level efficiency measures such as Tokens per Joule (established industry practice, not Arco vocabulary). A Steward optimizes Tokens per Joule; an acquirer, lender, or regulator asks about Revenue per Carbon.
Application
Revenue per Carbon is calculated from metered data, not estimation: token consumption billed per agent and per provider is converted to energy through published per-token figures, and to CO2e through regional grid carbon intensity, then aggregated to the business level per reporting period. A Steward tracks the engineering-level equivalent, Tokens per Joule, to make the accuracy-versus-energy tradeoff at the task-class level; Revenue per Carbon is the roll-up an acquirer, lender, or regulator reads, not a number the Steward optimizes directly.
Context
Revenue per Carbon is the environmental analogue to the labour-cost metrics this body of work already establishes. Where a traditional business is measured on revenue per employee, and an agentic business can be measured on Labor-to-Compute Substitution or revenue per token, Revenue per Carbon denominates output in the unit regulators, acquirers, and institutional investors are converging on. The claim is not that an autonomous business is automatically greener than a human-staffed one — a poorly calibrated agentic stack can consume significant energy. The claim is narrower and verifiable: an autonomous business's operational footprint is overwhelmingly metered inference rather than estimated human activity, which makes its footprint provable to the kilogram from billing data, at a granularity no workforce-based business can match. Verifiability, not automatic virtue, is the structural advantage.
