The Carbon Footprint Index
How much carbon does your favorite company produce? The Carbon Footprint Index is building the most comprehensive, publicly accessible database of corporate carbon emissions on the web. We aggregate, normalize, and present emissions data from thousands of organizations so that consumers, investors, and researchers can make informed decisions.
How It Works
We collect carbon footprint data from multiple sources:
- Corporate sustainability reports — Annual disclosures from publicly traded companies
- CDP (Carbon Disclosure Project) — The global standard for corporate environmental reporting
- EPA and regulatory filings — Facility-level emissions data from government databases
- Academic and NGO research — Peer-reviewed studies and investigative analyses
All data is normalized to metric tons of CO₂ equivalent (tCO₂e) per year and categorized by scope:
| Scope | What It Covers | Example |
|---|---|---|
| Scope 1 | Direct emissions from owned facilities and vehicles | Factory smokestacks, company fleet |
| Scope 2 | Indirect emissions from purchased electricity and heat | Office power consumption |
| Scope 3 | All other indirect emissions across the value chain | Supply chain, product use, employee commuting |
Industry Rankings
Highest Emitting Industries
- Energy & Utilities — Fossil fuel extraction, refining, and power generation
- Transportation — Airlines, shipping, trucking, and automotive manufacturing
- Materials & Mining — Cement, steel, aluminum, and chemical production
- Agriculture & Food — Livestock, fertilizer production, and land use change
- Construction — Building materials, on-site equipment, and embodied carbon
Most Improved
Companies and sectors showing the greatest year-over-year reductions in emissions intensity, highlighting real progress rather than just offsets.
Featured Companies
- Apple — Achieved carbon neutral corporate operations; working toward full supply chain neutrality
- Microsoft — Committed to being carbon negative by 2030 and removing all historical emissions by 2050

Why Track Carbon Footprints
- Consumer power — Informed purchasing decisions create market incentives for lower-carbon products
- Investment screening — ESG-conscious investors need reliable emissions data to assess climate risk
- Accountability — Public data holds companies to their net-zero commitments
- Benchmarking — Companies can compare their emissions intensity against industry peers
Our Methodology
Every data point in the Index is sourced, dated, and linked to its origin. Where companies report their own data, we note it. Where independent estimates are used, we explain the methodology. Transparency is not optional — it is the whole point.
