of a programmatic ad plat-form’s emissions originate from scope 3 activities.
Digital technologies contribute approximately 4% of global GHG emissions , comparable to the aviation industry, and this figure is rising at a concerning rate of 9% annually. Studies indicate that online advertising accounts for 10-20%of internet infrastructure energy use, with 1 million ad impressions generating approximately 1,000 kg of CO2 emissions. Even seemingly small interactions, like a single email, generate approximately 4g of CO₂-equivalent gases.
Unlike other sectors with established environmental disclosures, the digital advertising industry has yet to embrace carbon accountability fully, hindering efforts to understand and mitigate its contribution to climate change. According to a survey on “why businesses are not prioritizing greener websites,” 38% of marketers are simply unaware of the environmental impact of their digital footprint.
As the digital advertising industry continues to grow (projected to surpass $1.1 trillion by 2027), the environmental cost of these challenges becomes more evident. Addressing these issues necessitates a fundamental change toward more sustainable and responsible advertising practices.
This whitepaper examines how AI-driven solutions can drive sustainability in digital advertising by reducing emissions, improving targeting efficiency, and enabling low-carbon ad delivery. A clear understanding of the industry's carbon footprint requires analyzing emissions across each stage of the ad lifecycle.
The following section delves into the key contributors to these emisions within digital advertising operations.
While digital advertising eliminates paper waste, it carries a significant yet often overlooked carbon footprint. Every ad impression requires computational power, network bandwidth, and energy-intensive infrastructure, contributing to emissions at multiple stages, from production to delivery and beyond.
A single ad campaign can generate around 70 tons of CO2, the same as the carbon footprint of producing 46 million plastic straws.
These emissions stem not only from digital operations but also from travel, logistics, and office activities that support the advertising industry.
Here's a breakdown of the key phases where these emissions occur:
Every step in digital ad creation contributes to carbon emissions, including filming, editing, high-resolution rendering, and cloud storage.
A single video shoot can produce over 200 tons of CO₂eq, with transportation for location scouting, equipment, and crew making up 80% of emissions.
Delivering and viewing ads and the energy used by data centers and network infrastructure generate continuous emissions.
Data centers, major electricity consumers, could double their consumption to 4% by 2030. Ad distribution relies on content delivery networks and servers that require constant power.
Emissions also come from end-user devices like smartphones, laptops, and smart TVs, which consume energy to load and play ads.
This phase depends on DSPs, SSPs, and DMPs for audience segmentation, running millions of calculations per second, especially for programmatic ads. These processes consume significant energy to support ad auctions and real-time delivery.
Programmatic inefficiencies, such as redundant ad requests and excessive auctions further increase emissions, making this one of the most carbon-intensive stages of digital advertising.
Sustainability in digital advertising is gaining prominence, evolving from a secondary consideration to a critical business priority. Stakeholders across the ecosystem, including brands, agencies, technology providers, and regulators, are now advocating for measurable carbon reduction strategies.
In response to the escalating carbon footprint of digital advertising, numerous global initiatives and industry leaders are adopting proactive measures.
