Founded in December 2021, Scope3 introduced a comprehensive emissions model that maps and calculates the carbon footprint of the entire digital advertising supply chain. The model enables every company in the ad ecosystem to see carbon emissions and then make data-driven decisions that optimize toward carbon reduction. It also powers the carbon reduction products brands and marketers are using today to reduce their emissions.

Scope3 works with stakeholders across every part of the media supply chain, including verification partners, DoubleVerify and Integral Ad Science; dozens of brands and publishers, including Sanofi, MasterCard, Insider, and Microsoft’s MSN; and nearly every global agency holding company, including GroupM and IPG.
