Emissions data

Emissions data quantifies greenhouse gases released by companies, facilities, products and activities, usually expressed in tonnes of carbon dioxide equivalent (tCO2e). Sustainability teams use it for supplier engagement and Scope 3 accounting, asset managers for portfolio carbon footprints and transition analysis, and banks for financed emissions.

Typical fields

• Entity identifier (company, facility or product) and reporting year
• Scope 1, Scope 2 (location-based and market-based) and Scope 3 by category
• Emissions intensity per unit of revenue or output
• Data type flag: reported, estimated or modelled
• Source document and verification or assurance status
• Reduction targets and base years where disclosed

Sources and methods

Reported data comes from annual and sustainability reports, regulatory registries such as emissions trading and pollutant release registers, and voluntary disclosure programmes. For companies that do not report, providers estimate emissions using sector averages, revenue-based factors or physical activity data. Product-level figures come from life-cycle assessments and emission factor databases. Corporate accounting generally follows the GHG Protocol corporate and Scope 3 standards.

Delivery and pricing

Datasets are typically sold as annual licences covering a universe of issuers or facilities, delivered as files, data shares or API. Price depends on coverage, history, the share of reported versus modelled data and whether Scope 3 detail by category is included.

Before you buy

• Check what share of values are reported versus estimated, and how each is flagged.
• Ask how Scope 3 is estimated and which categories are covered.
• Confirm that both market-based and location-based Scope 2 are provided.
• Review how company restatements are handled.
• Check identifier coverage, such as LEI or ISIN, for matching your portfolio.
