CarbonLayer
A company focused on research into the environmental impact of AI inference and the transparency of routing decisions. It publishes the Impact Receipt article series, exploring the cost, reliability and carbon footprint estimation of LLM routing.
Timeline (last 90 days)
The CarbonLayer team is exploring the concept of an 'AI Impact Receipt', attempting to answer whether the way AI environmental impact is described can be standardized without standardizing misleading assumptions.
In the third part of its article series, CarbonLayer has already discussed the fields an AI Impact Receipt should contain: workload information, model identity, latency, environmental metrics, methodology, provenance, and uncertainty.
CarbonLayer proposes that the goal of standardization should not be to require every AI provider to calculate environmental impact in exactly the same way, because different providers use different hardware, workloads, measurement systems and data sources, and a universal calculation methodology is not realistic in the short term.
CarbonLayer's position is: a number that looks precise but lacks sufficient supporting evidence should not be returned; a receipt can return a structure in which each metric's status is 'unavailable' and its value is null; zero is a value, unavailable is an evidence status, and the two should never be interchanged.
CarbonLayer prefers not to invent confidence scores, but instead uses evidence type and provenance to indirectly express the degree of trustworthiness, avoiding a false sense of precision.
CarbonLayer currently has two different demo interfaces.
What CarbonLayer produces using the /api/inference endpoint is a simulated routing receipt, and it has not yet implemented verifiable real-time inference across external providers.
CarbonLayer said that the subsequent Part 4 will explore whether impact metadata can be standardized across models, providers, and tools, and Part 5 will attempt to consolidate it into a draft open API specification.
One cannot assume that optimizing one of cost, performance, reliability, or environmental impact will automatically improve the others.
The research directions CarbonLayer lists include cost control, latency preference, provider reliability, model and provider selection, and decision transparency, but these are research directions, not delivered feature commitments.
