In this blog, our Data & Innovation Strategist, Dimitris Beis, shares his thoughts on why sustainability skills are becoming business-critical in digital advertising, and how education can help professionals across the ecosystem make more informed, credible, and practical decisions.
Sustainability skills are becoming business-critical in digital advertising. Our latest State of Readiness: Sustainability in Digital Advertising Report found that 62% of companies working on sustainability have observed reputational improvements as a result, while compliance with regulation has become the leading driver of sustainability efforts across the ecosystem.
This matters because sustainability is no longer a side conversation or a specialist discipline. It is increasingly influencing how digital advertising is planned, evaluated, reported, and improved. For professionals across brands, agencies, media owners, and ad tech, understanding sustainability is becoming essential to making informed decisions, responding to market expectations, and building credibility with clients and partners.
Sustainability Is Now a Core Industry Skill
For many digital advertising professionals, sustainability can still feel complex. The language of carbon accounting, emissions scopes, frameworks, methodologies, and reduction pathways is not always easy to navigate. Yet these concepts are increasingly relevant to day-to-day decision-making.
A media buyer may need to understand how campaign set-up choices can affect environmental impact. A strategist may need to consider sustainability alongside reach, frequency, cost, and effectiveness. An ad tech specialist may need to think about how infrastructure, auction dynamics, data processing, and supply path decisions contribute to emissions.
This is why sustainability skills matter. They help turn ambition into action. With the right knowledge, professionals can ask better questions, interpret data more confidently, and identify meaningful opportunities to reduce impact.
The Supply Chain Is Complex
Digital advertising is powered by a highly interconnected ecosystem. Every campaign can involve multiple platforms, partners, data processes, creative assets, auctions, servers, devices, and measurement systems. This complexity is one of the reasons digital advertising is so effective, but it also makes environmental measurement and reduction more challenging.
Understanding where emissions are generated across the digital advertising supply chain is an essential first step. It allows teams to move beyond generic statements and begin looking at the specific activities, decisions, and operational practices that influence carbon impact.
This does not mean every professional needs to become a carbon accounting expert. But it does mean that more people across the industry need a working understanding of the principles, terminology, and methodologies that support credible sustainability action.
Better Skills Lead to Better Decisions
Sustainability in digital advertising is not only about measurement. Measurement is important, but it is only valuable if it supports better decisions.
Professionals with sustainability knowledge are better placed to assess trade-offs, challenge assumptions, and avoid common pitfalls. They can understand the difference between estimating emissions and reducing them, recognise why robust methodologies matter, and identify where optimisation may be possible, from campaign planning and media buying to supply path choices and operational efficiency.
As the industry works toward greater alignment around standards and frameworks, shared approaches will be most effective when professionals understand how to apply them in practice.
Building the Foundation
At IAB Europe, we believe education plays a central role in supporting the industry’s sustainability journey. That is why we have developed our Condensed Course on Environmental Sustainability in Digital Advertising, with the next one taking place online on Wednesday, 15th July.
This three-hour, interactive course is designed for marketing, media, and ad tech professionals who want a clear and practical introduction to sustainability in the context of digital advertising. Across one live session, together we will explore key sustainability frameworks, digital advertising emissions, and actionable strategies to reduce carbon impact.
The curriculum covers three core areas:
Why Now?
Sustainability is part of how digital advertising is planned, evaluated, and improved. Organisations that invest in skills now will be better prepared to respond to client expectations, regulatory and reporting pressures, industry standards, and their own environmental commitments.
The path to a more sustainable digital advertising ecosystem depends on shared knowledge, credible methodologies, and practical action. Building sustainability skills is one of the most important steps we can take to support that progress.
Join IAB Europe’s Condensed Course on Environmental Sustainability in Digital Advertising here on Wednesday, 15th July, to gain the foundational knowledge and practical tools needed to understand, estimate, and reduce the carbon footprint of digital advertising activities.
