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 is 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. This highlights the importance of having high-quality GHG emissions estimation models and accurate data to support investment decision-making.

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

Our Carbon Emissions Data is backed by best-in-class multi-factor regression models to estimate GHG emissions. With our sophisticated estimation models and high-quality data, investors can respond to regulatory requirements such as the EU Action Plan and disclosure expectations such as the TCFD and PRI. Our enhanced Carbon Emissions Portfolio Reports also provide rich insights into the portfolio-level performance on GHG emissions compared to a preferred benchmark.

Best-in-Class Estimation Models

Our estimation models for Scope 1, 2 and 3 emissions follow a common model framework across all environmental metrics and considers subindustry, geographical location, and a company’s size. This common model framework facilitates consistency and comparability.

Our models also include specific factors, which offer the flexibility to adjust for structural differences in the underlying data and can address the limitations of data availability. The company activity data in our Scope 1 and 2 models allows the estimation models to account for subindustry variation in business models and GHG-generating activities.
