What data do you provide?

ISS ESG provides carbon footprint data on a universe of more than 25,000 issuers covering a range of asset classes. ISS ESG’s comprehensive data base of greenhouse gas emissions include both reported emissions data and modelled estimations for non-disclosed emissions, estimated using a sophisticated modelling system, which includes over 800 climate-relevant sector and subsector-specific models. 

The modelling system was developed over the course of three years in partnership with the Swiss Federal Institute of Technology. Data factors include the following: emissions data; emissions intensity data; emissions data source and trust metrics; and emissions targets. Carbon footprint data is available for the following asset classes: listed entities, fixed income, private equity, listed and unlisted infrastructure, real estate, real assets and more.

Where and how do you source your data?

For scope 1 and 2 carbon emissions, ISS ESG collects self-reported greenhouse gas emissions data from public available sources, including corporate social responsibility reports, CDP, investor relations communications, websites and others. This data is assigned with a trust metric to indicate the quality of self-reported data. 

For non-reporting companies, or those who report with a low trust metric, ISS ESG uses in-house emissions modelling methodology, allowing ISS ESG to calculate greenhouse gas emissions emissions of companies based on those criteria most relevant to their line of business.

For scope 3 emissions data, ISS ESG uses in-house modelling system, which conceptually differentiates between emissions from upstream/downstream supply chains and emissions from the “use phase” of a company’s product or service.
