Corporate Sustainability Data & Emissions Database

Corporate sustainability data

Corporate sustainability data, made searchable

Mycelium is a corporate sustainability data platform that helps you search company carbon emissions, review disclosure status and compare sustainability performance across industries.

Our emissions database brings together company-level carbon data, supplier information and sustainability disclosures in one place, with clear sources and an open methodology.

Why it matters
