LONDON, UNITED KINGDOM – VIOOH has announced its 2024 full-year emissions intensity results, reaffirming the company’s position as a sustainability leader in the programmatic digital out-of-home (pDOOH) space. According to the latest figures, VIOOH achieved an emissions intensity of 0.041 grams CO2e per ad impression for 2024, marking its third consecutive year operating well below both industry and open web benchmarks.
This year’s measurements align with version 1.2 of the Global Media Sustainability Framework (GMSF), launched by Ad Net Zero in June 2025 as the global standard for cross-channel emissions tracking. Working with sustainability partner Cedara, VIOOH incorporated the new GMSF methodology to provide advertisers with more robust, transparent, and comparable emissions calculations.
Under the updated framework, VIOOH’s emissions intensity performs significantly better than major digital channels, with programmatic display averaging 0.84g CO2e per impression and programmatic video reaching 1.24g CO2e per impression. This translates to pDOOH on VIOOH being over 20 times more carbon-efficient than display and more than 30 times more efficient than video. The efficiencies are driven by the broadcast nature of DOOH, increasingly renewable-powered screens, and a streamlined supply chain.
While the new GMSF methodology prevents a like-for-like comparison with previous years, the results continue to reinforce VIOOH’s exceptional environmental performance. “Our 2024 results demonstrate that buying DOOH programmatically through VIOOH continues to provide a clear point of difference for advertisers seeking to make more sustainable media choices,” said Jean-Christophe Conti, CEO of VIOOH. He emphasized pDOOH’s ability to deliver effective, brand-safe, fraud-free media while supporting sustainability goals throughout the marketing ecosystem.
Cedara CEO and Co-Founder David Shaw added “VIOOH’s consistent progress in sustainable media efficiency is a testament to their commitment to transparent accountability and understanding the environmental impact of pDOOH. Their leadership is setting a new benchmark for the industry and enabling brands to choose more responsible media pathways.”
Cedara’s analysis covered business operations, media delivery activity, data center usage, and media owner data. Log-level bidstream data was also included to ensure accurate emissions accounting for programmatic delivery.
Founded in 2018 and headquartered in London, VIOOH connects buyers and sellers in a premium global digital OOH marketplace, currently trading programmatically in 35 markets and partnering with over 50 DSPs. Cedara, founded in 2021, continues to accelerate sustainability transformation across the media industry through enterprise-grade measurement and optimization technologies.
