  • The ET Carbon Dataset comprises the most comprehensive and granular corporate value-chain greenhouse gas emissions data on the market.


  • The dataset is rigorously quality-assured according to a nine-year time series with inferences to fill gaps in company reporting.


  • It is unique in providing cleaned, quality-assured and investment-grade data on the full spectrum of company operational and value chain emissions, covering Scope 1, 2 and all 15 categories of Scope 3.


  • Directly analysed data covers leading benchmarks including MSCI ACWI, MSCI World, S&P 500, Stoxx 600 and FTSE 100, with data available for over 30,000 securities.


The ET Carbon Dataset is used by investors as an input into risk models and investment decision-making processes, to perform in-house carbon footprint analysis and for reporting purposes. It includes information on the completeness of the data publicly reported by companies, including whether it has been third-party assured, as well as statistical analysis and estimation models for non-disclosing companies. The ET Carbon Dataset allows for an evaluation of the absolute and relative greenhouse gas emissions of each company and their trajectory over time, as well as an assessment of the amount of renewable energy purchased by each company and the trend over time.

ET collects company emissions data from public sources such as company Annual Reports, Sustainability Reports and company websites. ET is unique in being fully transparent with its data, indicating where data points have been reported or modeled



Engaged Tracking has observed increases in both the quantity and quality of reported Scope 3 emissions data. Disclosure of Scope 3 emissions is increasing year on year, with more companies disclosing Scope 3 emissions data and more Scope 3 categories being reported by companies. Between 2013 and 2018, the number of companies disclosing at least 11 of the 15 Scope 3 categories quadrupled.

While enhanced Scope 3 disclosure is encouraged, the bulk of a company’s emissions will normally sit within a handful of the Scope 3 categories, with significant differences between sectors. For example, the categories Use of Sold Products and Investments would be of significant importance to the Oil & Gas and Financial Services sectors respectively. It is therefore vital to understand the material Scope 3 categories within each sector.

Engaged Tracking actively undertakes such exercises for each sector.  Based on a recent case study for the SASB SICS Health Care Sector, the most material Scope 3 categories are Purchased Goods and Services, Capital Goods, and Use of Sold Products. These 3 categories make up 84.7% of the total average emissions of all 15 Scope 3 categories for the Health Care Sector.


In order to accurately evaluate company performance and the full extent of exposure to carbon risk, a company’s emissions throughout its entire value chain (Scope 3) must be considered. Including only Scope 1 and 2 emissions in the analysis of carbon risk exposure can mean a considerable underestimate of exposure to carbon-related risks. 

ET’s own research evaluating disclosed emissions data has shown that Scope 3 emissions typically account for more than 85% of a company's total emissions. The Task Force on Climate-related Financial Disclosures (TCFD) also suggests that Scope 3 emissions should be considered where material. ET incorporates all 15 Scope 3 categories, providing access to the most granular and comprehensive dataset.
