Our Mission

Our goal is to provide high-quality, open sustainability data for businesses, governments, researchers, and other organizational users worldwide. As a first step, we're bringing the two most widely used scope 3 emissions models under one roof – USEEIO and CEDA – ensuring continuity and reliability for institutional sustainability measurement.

In the coming months, we'll bring these two leading models together as a single global, open MRIO (Multi-Regional Input-Output) model that can offer a durable common standard for companies, governments, and researchers.

Quality data is the foundation of great sustainability work. We aim to provide the cornerstone.
