Carbon Emissions Data ​

The foundation of climate research


While corporate disclosure on greenhouse gas (GHG) emissions is improving, reporting on Scope 1, 2 and 3 emissions remains limited. Yet investors need reliable GHG emissions information to assess the climate risks facing their portfolio companies and to fulfill mandatory and voluntary regulatory requirements.

Morningstar Sustainalytics’ Carbon Emission Data provides investors with powerful insights to assess and analyze companies’ GHG emissions.

Our high-quality data set is built on the most up-to-date reported carbon emissions disclosure data from over 7,500 companies, with our sophisticated estimation models expanding our coverage to 16,000+ companies. This allows investors to respond to regulatory requirements like the EU Action Plan and disclosure expectations such as the TCFD, ISSB, and PRI.

About our GHG Emissions Estimation Models

Morningstar Sustainalytics' multi-factor regression models for Scope 1, 2 and 3 GHG emissions follow a common framework which:

  • Considers environmental metrics and factors like sub-industry, geographical location, and a company’s size, facilitating consistency and comparability to more accurately estimate GHG emissions. 
  • Offers the flexibility to adjust for structural differences in the underlying data and addresses the limitations of data availability
  • Accounts for sub-industry variation in business models and GHG-generating activities, with the company activity data in our Scope 1 and 2 models.
