About the research
The Acceptable Ads Committee (AAC) conducted a qualitative study to better understand the perspectives of online users regarding sustainability. This study addressed key questions, including user awareness of carbon emissions associated with their internet usage, their views on “sustainable advertising” and strategies to reduce carbon footprint. These findings will form the basis for a larger quantitative study that the AAC will commission later this year.
Key findings
Brands and agencies must bear responsibility to reduce CO2
Users feel that the responsibility for reducing the environmental impact of online advertising falls primarily on advertising agencies and the brands commissioning the ads.
Participants suggested several ways that brands and agencies could contribute to emissions reductions, such as:
- Implementing formal certifications or compliance standards
- Reducing the no. or types of energy-intensive ad formats
- Requiring advertisers to offset carbon emissions from ads.
The path to advertising sustainability is unclear
Users want the carbon emitted by online ads to be reduced, but most are unable to elaborate on how this can be achieved. Notably, users perceive certain types of ads (primarily video ads, but also interactive ads, animated ads and pop-ups) to be more energy-intensive and therefore negatively impact the environment more.
There is a gap in users’ understanding of the online advertising ecosystem, which suggests that industry stakeholders should collaborate on providing clear information and guidelines for sustainable advertising practices.
Users want credible industry-wide standards
Making online advertising more sustainable is difficult given the industry complexity and number of stakeholders involved. The consensus from users was that sustainability initiatives require a united industry effort spearheaded by independent and credible organizations.
While some participants mentioned the need for a governing body or regulator to oversee emissions reduction in online advertising, others were unaware of any existing such bodies. This indicates a potential opportunity for industry associations or organizations to step in and fill this role.
[…] someone who’s credible and has authority over the environment, or someone you can trust. You can’t have people just making up their own badges and saying this is legitimate. You need a body to authorize it.

What is needed
Without reliable data, effective management is difficult. Credible information is the catalyst for transformative actions and behavioral shifts.
The IAB Tech Lab has released a comprehensive starter guide, empowering stakeholders to initiate immediate changes. Brands, agencies, publishers and ad tech companies are eager to make a difference – they need clear directives to commence their sustainability journey.
