Carbon Efficiency Metrics of Programmatic DOOH
Comparing Emissions Across Advertising Channels
A striking revelation in the realm of sustainable advertising comes from VIOOH’s 2024 emissions intensity data, which pegs programmatic DOOH at a mere 0.041 grams of CO2 equivalent (CO2e) per ad impression. When juxtaposed with programmatic display advertising at 0.84g CO2e and video at 1.24g CO2e per impression, DOOH demonstrates over 20 times greater carbon efficiency than display and over 30 times more than video. This disparity underscores a transformative potential for advertisers seeking to minimize their environmental footprint.
The efficiency stems largely from the broadcast nature of DOOH, where a single advertisement displayed on a digital billboard can reach numerous viewers simultaneously in high-traffic locations. Unlike digital display or video, which often require individual data transmissions per user, DOOH distributes energy consumption across a broader audience, significantly lowering the per-impression carbon cost. This structural advantage positions it as a standout in media planning for sustainability-focused campaigns.
Measurement Standards and Industry Benchmarks
The credibility of these metrics hinges on standardized methodologies like the Global Media Sustainability Framework (GMSF) version 1.2, developed by Ad Net Zero. This framework provides a consistent approach to calculating emissions across the advertising delivery chain, from server usage to screen infrastructure. Third-party validations, such as those conducted by Cedara using log-level bidstream data, further enhance transparency and trust in the reported figures.
These standardized benchmarks not only validate current data but also pave the way for future industry norms. As advertisers increasingly rely on carbon efficiency metrics alongside traditional performance indicators, the adoption of DOOH is projected to grow, fueled by trust in consistent measurement practices. Such developments signal a shift toward integrating environmental impact into strategic decision-making across the sector.
Key Factors Driving Carbon Efficiency in Programmatic DOOH
One of the primary drivers behind programmatic DOOH’s impressive carbon efficiency is its shared audience model. By displaying content in bustling public spaces, a single ad can engage multiple viewers at once, unlike the one-to-one delivery of digital display or video ads. This inherent characteristic drastically reduces the energy required per impression, making DOOH a uniquely sustainable channel in high-visibility environments.
Additionally, platforms like VIOOH streamline the supply chain by minimizing intermediaries in the ad delivery process. Compared to traditional digital advertising, which often involves multiple layers of platforms and verification services, this leaner approach cuts down on computational demands and associated emissions. The result is a more direct and less resource-intensive path from advertiser to audience.
Further amplifying this efficiency is the integration of renewable energy sources to power many DOOH screens within extensive networks. Coupled with technological innovations such as real-time bidding and aggregated data measurement systems, which reduce unnecessary data processing, these efforts collectively bolster the channel’s low-carbon profile. Such advancements highlight how infrastructure and technology converge to support greener advertising practices.

Despite its advantages, programmatic DOOH faces hurdles in widespread adoption, notably a knowledge gap among industry professionals. Surveys indicate that 36% of marketing experts lack a clear understanding of this channel, which can deter investment and slow integration into broader media strategies. Bridging this gap remains a critical challenge for expanding its reach.
Beyond specific barriers to DOOH, the advertising sector grapples with the overarching issue of digital advertising’s substantial carbon footprint. As part of an industry where digital services contribute significantly to global emissions, finding scalable, low-impact alternatives is paramount. This context underscores the urgency of shifting toward channels that inherently produce fewer emissions without compromising on reach or effectiveness.
Solutions are emerging through initiatives like industry education, exemplified by IAB Australia’s programmatic DOOH buyer’s guide, and collaborations with carbon tracking firms such as Scope3 and Cedara.
