Case Study: Hearts & Science reduces client emissions by 51% with Index Exchange

Hearts & Science reduces client emissions by 51% with Index Exchange

Hearts & Science, a leading media agency, faced a challenge from a major global financial institution client that wanted to lower its advertising-related carbon footprint. The agency partnered with Index Exchange to fine-tune its media-buying strategy, aiming to eliminate wasteful or high-emission inventory without compromising campaign performance.

Index Exchange provided a solution by running the campaign on its exchange, which proactively audits sites to eliminate made-for-advertising content. Through a partnership with Scope3, Index provided access to Green Media Product (GMP+) inventory packages that prioritize lower-emission inventory. The results were significant, including a 51% reduction in carbon emissions per impression, a 70% lower cost per landing, and a 13% higher viewability, proving sustainability and performance can go hand-in-hand.
