This report on digital advertising’s carbon footprint reveals that for half the studied countries, emissions have decreased by an average of 9.3% over six months. A key finding is the substantial impact on carbon reduction by removing high-emission 'climate risk inventory,' which could cut emissions by over 25% globally. In countries like Germany, the US, and the UK, this reduction could be even more substantial.

The study highlights the variation in emissions across countries and underscores the significant opportunity for carbon reduction in the ad industry. Aggressive action in reducing emissions from the ad selection process can greatly reduce the industry's carbon footprint.

Urging timely and aggressive action, the report stresses the importance of reducing emissions now to impact future levels. Focusing on ad selection presents a major opportunity for emission reduction in digital advertising, making a significant difference in the industry's overall climate impact.
