Server instructions

Mycelium is an open-access corporate carbon emissions database. Use these tools to answer questions about a company's reported or estimated greenhouse gas emissions, its Mycelium Score (0 to 10, higher is better) and Transparency Score, and how it ranks against its industry peers. Typical flow: call search-entities with the company name, pick the right match, then call get-entity-profile (scores, industry, reporting years) or get-emission-figures (full per-scope figures for one reporting year, in the OpenCCF data model). Provenance matters: every emissions line is tagged as reported by the company or estimated by Mycelium. Always preserve that distinction when presenting figures, and never present an estimated figure as one the company disclosed itself.
