ISS ESG - Potential Avoided Emissions Data

Data category

Environmental data

Brief description of the data offering

ISS ESG has developed an innovative methodology that allows investors and corporates to assess the potential avoided emissions of their investments, i.e. emissions that would have been released if a particular action or intervention had not taken place. ISS ESG's methodology covers potential avoided emissions throughout the value chain, for instance, those from an investees' more carbon-efficient products or services.

While a carbon footprint focuses on gross greenhouse gas emissions and an impact assessment tries to capture trends, a third dimension of climate impact is the potential of GHG savings deriving from an investee's product or service. This is particularly relevant for those investments that offer solutions and contributions to a low carbon future through their focus or product portfolio.

ISS ESG's Potential Avoided Emissions methodology can be applied to a variety of assets, including public and private equity, bonds and infrastructure projects. Through ISS ESG's proprietary platform, DataDesk, investors can access the PAE generated from utilities generation of renewable energy and the emissions avoided from turnkey technologies generating electricity from renewable source e.g. through wind, solar, hydro and geothermal. The dataset includes more than 250 companies covering the relevant companies that are included in the most widely used benchmarks and indices in the world.

For investments in infrastructure projects or companies with a complex product portfolios, ISS ESG provides a bespoke approach to analysing Potential Avoided Emissions. The methodology covers the emissions throughout the value chain, including emissions from an investees' more carbon-efficient products or services. The assessment can be applied to companies, infrastructure investments, real estate investments and green bonds.

Where and how do you source your data?

Thorough data collection is conducted by both using publicly available information and directly contacting investees to provide data on avoided emissions. If a holding is able to provide their own avoided emissions calculations this data is reviewed and amended if deemed imprecise.

If no data is provided, a variety of methods can be applied (e.g., an analysis of climate friendly product lines; an extrapolation based on sectoral key figures from projects/companies).

Who are the data users?

Data is used by a broad range of institutional investors, asset managers, asset owners, fund managers, banks, government institutions, universities and research firms. 

What is the cost for your data offering?

Pricing is based on the method by which data is delivered. ISS ESG can provide data via its proprietary platform, DataDesk, or via data feed. Pricing for this solution is available upon request.
