Global Scope 1, 2 and 3 emissions data is now at your fingertips Historically, corporate emissions disclosures sat buried in thousands of sustainability PDFs, inconsistent, unstructured, and hard to compare. We built an open & free emissions registry to change that.
- Scope 1, 2, and 3 emissions, searchable by sector and year
- Full Scope 3 category breakdowns
- Sector breakdowns, scope mix ratios, and Scope 3 trends
- Top Scope 3 categories per industry
- Outliers whose scope mix deviates from their sector average
Scope 3 dominates most corporate footprints; understanding your value chain starts with data you can verify. The registry is free, no login required, and updated continuously by our AI agents.
