How to find a company's sustainability report and emissions data

Most large companies publish their greenhouse gas emissions every year, but the numbers can be spread across several documents. This is a practical checklist for finding the latest Scope 1, 2 and 3 figures for a company.

1. Start with polluer.com

Search the company on the homepage or browse A–Z. Each page lists the report periods we found, the headline emissions figure, the scope breakdown and any targets. Use it as a starting point, then confirm the numbers in the original report: our data is AI-extracted and may contain errors.

2. The company's own website

• Look for sections called Sustainability, ESG, Responsibility, Impact or Investors.
• Many companies publish an ESG data book or data appendix (often Excel or PDF) that has more detail than the glossy report, including Scope 3 by category and several years of history.
• Search the web for "company name" sustainability report 2024 filetype:pdf or "company name" scope 3 emissions.

3. The annual report and regulatory filings

• European Union: companies within the scope of the Corporate Sustainability Reporting Directive (CSRD) publish a sustainability statement inside the management report, following the ESRS standards (climate is ESRS E1). In 2025 the EU postponed and narrowed parts of these requirements as part of its "Omnibus" simplification package, so coverage depends on company size and reporting year.
• United Kingdom: quoted companies and large unquoted companies report energy use and emissions in the directors' report under Streamlined Energy and Carbon Reporting (SECR), in place since April 2019.
• India: the top 1,000 listed companies by market capitalisation file a Business Responsibility and Sustainability Report (BRSR) with their annual report.
• Hong Kong: listed issuers publish an ESG report under the HKEX ESG reporting rules.
• United States: there is no general federal requirement to disclose emissions in SEC filings, so look on the company website. California's climate disclosure law (SB 253) is phasing in Scope 1 and 2 reporting for large companies doing business in the state.

4. CDP

Thousands of companies answer the CDP climate questionnaire each year. Many responses are public and searchable on cdp.net, and they follow a consistent structure, which makes them easy to compare.

5. Targets: the Science Based Targets initiative

To check whether a company's reduction target has been independently validated, search the SBTi's target dashboard on sciencebasedtargets.org. It lists near-term and net-zero targets, the base year and the scopes covered.

6. What to check once you have the report

• The reporting period (calendar year or fiscal year such as April–March)
• Market-based vs location-based Scope 2 (explained here)
• Which Scope 3 categories are included
• Whether figures were restated for earlier years
• The level of external assurance
• The framework used (GRI, ISSB/IFRS S2, ESRS, TCFD and so on)
