Our process
Our process
Aggregate the data
We select key metrics on Scope 1-3 emissions, waste management, net zero targets, and external ratings. Data comes from company disclosures and trusted sources like Yahoo Finance, Sustainalytics, B Corp, and SBTi.
Constant evolution
Regular refreshes of data collection and ongoing quality control ensures the latest data is used for the most accurate, representative view at all times.
Benchmarked scoring
Our algorithm creates simple 0-5 Earthmarks for easy brand comparisons, peer-relative and performance-based.
Our process
Aggregate the data
We collect publicly available, third-party verified data from sources like Wikirate, Yahoo Finance, B Corp, and SBTi. This includes emissions, waste data, climate targets, and external ratings.

Regular refreshes of data collection and ongoing quality control ensures the latest data is used for the most accurate, representative view at all times.
Benchmarked scoring
Our proprietary rating algorithm benchmarks companies vs peers of the same size and sector for fair, meaningful comparisons.

Benchmarking & Alignment
Benchmarking & Alignment
Data normalises by revenue, scaled -1 to 1 (median 0) per sector to handle outliers.
Reported data: Company disclosures (i.e. Impact Reports) vary from audited to unaudited by size and governance with reporting inconsistencies. Location-based Scope 2 emissions are used by default; market-based used when available.
Ownership: Subsidiary data first; flags parent data use on profiles.
Modeling: Predicts gaps via revenue-based regression (trained on ground truth)—for insights only, not scoring.
Aligns with GHG Protocol (Scope 1-3 emissions) and ESRS/CSRD topics: E1 (Climate Change), E2 (Pollution), E5 (Circular Economy), S1 (Workforce), G1 (Business Conduct). Supports EU sustainability regulations and green claims compliance.

Disclaimer: Earthmark is a benchmarking tool, not a certification or audit. Scores use the latest publicly available, independently verified data, extracted and standardised via AI (large language models)—which may introduce errors or omissions—and are fluid, updating with new information. They are indicative only, not proof of sustainability performance; users should review underlying sources for their own views.
