Major Emissions Database Handed Over to Watershed and Stanford Following EPA's Discontinuation of Updates
Watershed Launches Cornerstone Initiative to Enhance Sustainability Data Access
Watershed, a leading provider of environmental data solutions, has announced the launch of a new initiative called Cornerstone in partnership with Stanford University's Stanford Sustainable Solutions Lab. The purpose of this initiative is to preserve and expand access to foundational, open-source sustainability data, particularly for measuring Scope 3 (value chain) emissions.
According to Watershed, Cornerstone will act as the hub for open access to two of the most widely used models for value chain carbon accounting and policy research: the US EPA's USEEIO and Watershed's global CEDA. These models currently calculate around 65% of global Scope 3 corporate carbon measurements.
The new initiative will merge USEEIO and CEDA into a single global, open, multi-regional input-output model, managed by Cornerstone. This enhanced model is expected to significantly improve the accuracy and detail of Scope 3 emissions measurement by enabling more comprehensive environmental impact assessments, including air and water quality, water use, and waste generation — going beyond just greenhouse gas emissions.
The EPA has reportedly announced that it will no longer update the USEEIO database. Cornerstone aims to ensure ongoing development and open access to these crucial data tools, assisting thousands of organizations worldwide in Scope 3 carbon accounting and reporting.
Dr. Wesley Ingwersen, former EPA lead and architect of the USEEIO model, will serve as Technical Director for Cornerstone. Other leaders of the initiative will include Dr. Sangwon Suh, Head of Science at Watershed and developer of CEDA, and Dr. Steve Davis, Professor at the Stanford Doerr School of Sustainability.
The Stanford Sustainability Lab will support ongoing model development, while Watershed plans to onboard additional open-source contributors over time. Dr. Ingwersen was let go from the EPA in July after signing a letter asking Administrator Lee Zeldin to reconsider the new direction of the agency.
Christian Anderson, co-founder of Watershed, hopes the combined models will help companies and organizations build and maintain momentum on sustainability. Cornerstone's aim is to maintain and expand access to key datasets used by companies to measure Scope 3 value chain emissions.
In 2023, Watershed acquired environmental database provider VitalMetrics, which created CEDA. The company launched an open and free version of CEDA earlier this year. The merged model is expected to be completed in the coming months.

- The Cornerstone initiative, a collaboration between Watershed and Stanford University's Sustainable Solutions Lab, aims to enhance access to critical sustainability data, particularly for measuring Scope 3 emissions, through the merger of two widely used models: the US EPA's USEEIO and Watershed's CEDA.
- This merged model, managed by Cornerstone, will provide more accurate and detailed Scope 3 emissions measurements, allowing for comprehensive environmental impact assessments that extend beyond greenhouse gas emissions, including air and water quality, water use, and waste generation.
- To ensure ongoing development and open access to these data tools, Cornerstone will be supported by the Stanford Sustainability Lab and plans to onboard additional open-source contributors over time.
- With the merger of USEEIO and CEDA, companies and organizations can expect to build and maintain momentum on climate solutions, as this combined model will help them effectively measure their Scope 3 value chain emissions.
