Scope3

Scope3 is a carbon emissions platform that calculates the carbon footprint of digital advertising supply chains. The company provides a collaborative sustainability platform that measures end-to-end emissions from across the media and advertising ecosystem and drives carbon reduction actions. The company collaborates with stakeholders including verification partners, brands, publishers, and global agency holding companies.

 Scope3 offers quick emissions calculations with campaign metrics available from multiple ad tech platforms and agencies. It has launched Climate Shield , a turnkey carbon footprint reduction solution for digital advertising, which automatically blocks high emissions ad inventory.

Scope3 enables Green Media Products (GMPs), carbon-neutral media, to purchase carbon removal contributions. GMPs can be upgraded to include carbon compensation to neutralize the remaining emissions. The company also provides custom carbon algorithms to reduce CO2 emissions within campaigns while balancing performance metrics for advertising effectiveness. In October 2024, the company expanded beyond advertising to tackle the climate impact of AI, releasing an open-source AI methodology that measures the environmental impacts of AI products and services.  

In November 2024, Scope3 acquired Adloox, an ad verification and insights platform, to strengthen its media sustainability solutions.
