GARM & Ad Net Zero announce global framework to measure media's carbon emissions

What next?

The next phase of work for GARM and Ad Net Zero will be to establish an efficient system to transfer emissions data between buyers and sellers, followed by validation of media GHG data using agreed industry voluntary standards. Uptake and adoption will be tracked, with the first results published in Q2 of 2025.

How each part of the global advertising industry can play a key role in driving this framework forward:

1. Advertisers are asked to check that the partners who measure GHG emissions from their media activities are using the Global Media Sustainability Framework.
2. Agencies can ensure their own tools or partners are using the Global Media Sustainability Framework and make GHG emissions a consideration for all media plans.
3. Media owners can supply the requested data to advertisers, agencies and other solutions providers in as much granularity as possible, continually improving the quality of this data over time.

How the framework was created:

Six cross-industry working groups – supported by the Responsible Marketing Agency (RMA) - have produced this comprehensive set of voluntary standards to help reduce varying approaches to measurement, data and reporting. This approach has ensured widespread support and action across the industry, with 70% of responding organizations saying they plan to implement the voluntary standards in ways that are relevant to their media operations.

Commentary from Ad Net Zero Community

Sebastian Munden, Chair, Ad Net Zero: “Today’s release of standard calculations for the carbon footprint of major media channels is a significant milestone for Ad Net Zero and the global ad industry. They are the starting point for creating a common currency for global voluntary adoption: a base for calculating reduction and accelerating progress. Concerted efforts to reduce the carbon footprint of media should go hand in hand with the efforts to support more sustainable choices to change the way we work and change the work we make. The ad industry has the business opportunity of a generation to be part of the solution.”

Rob Rakowitz, Initiative Lead, Global Alliance for Responsible Media: “We are proud to support Ad Net Zero and help the group to create an essential foundation for the industry to benchmark their activities. We are hopeful that this work stemming from our uncommon collaboration will allow industry stakeholders to pursue a larger transformation in voluntarily reducing emissions stemming from media campaigns.”

Marla Kaplowitz, President and CEO, 4A’s: “The 4A’s is proud to support the new GARM/ Ad Net Zero media measurement frameworks for establishing carbon emissions footprints for TV, digital, print, OOH, audio and cinema channels."

Bob Liodice, CEO, ANA: “The ANA is proud to support the marketing industry's collective advancement toward a common measurement framework for emissions reduction through Ad Net Zero and GARM. We will continue to collaborate with industry associations, brands, and partners to lower marketing’s environmental impact through the Global CMO Growth Council and ANA Sustainability Committee.”

Arthur Millet, General Manager, Alliance Digitale: “The GARM framework represents a significant step towards making digital marketing more sustainable. At Alliance Digitale, we embarked on this journey two years ago with the SRI, aiming to create a unified measurement framework for digital carbon emissions. We are excited to see that the SRI x Alliance Digitale framework has served as a crucial foundation for a worldwide solution. A lot has been accomplished, and there's still work to do. We believe that sustainability is primarily about collaboration, and we would like to thank GARM for facilitating this. We hope we will continue this collaborative work for the next steps.”

Dr Bill Wescott, Chair, Climate Science Expert Group, Brain Oxygen: “This framework, paired with production emissions standards like AdGreen and verified enterprise level emissions inventory reporting across the ad sector, enables advertising firms to be aligned with their stakeholders’ needs, particularly advertisers who are already following established climate standards for all other activities. Like current climate standards with continuous improvement processes, we are counting on fact-based feedback from those implementing this initial version so that future versions will be even more accurate and practical.”

Isabel Massey, VP of Media, Connections & Content, Diageo: “Diageo recognizes the urgency of a standardized framework to measure media carbon emissions across the industry, and we see it as a key step in reducing carbon footprint.”

Tamara Daltroff, CEO, EACA: “This Framework was urgently needed and is a great achievement for media agencies and the advertising industry. It has been an intense journey to get to today’s point. It is now up to advertisers, agencies and media owners to make the best use of it. At EACA, we encourage collaborative, positive action towards reducing carbon footprint. It is good to see the industry coming together as a lot still needs to be done.”

Michael Todd, Global Director, Industry Relations, Google: “We are proud to have worked closely with the GARM and ANZ community to arrive at this important milestone. Standardization is a vital component in driving the industry towards making more sustainable media choices and bringing more clarity to this area is an important achievement. This has been a true team effort and we are excited to continue to work with GARM, Ad Net Zero and our partners to contribute to the next stage in this process to further refine the framework.”

Stephanie Betrand-Tassilly, Global Chief CSR Officer, Havas: “Working with our peers to define a common carbon metric makes perfect sense. At Havas, we’re already measuring the carbon impact of our creative, events and media campaigns, but today we want to go further, to work towards a set of industry standards. Collaboration is key and will enable us to accelerate the decarbonization of the advertising sector.”

Having agreed standards for calculating media supply chain emissions is the cornerstone of decarbonising commercial media. The UK was the launch market for Ad Net Zero and we intend to continue the pioneering spirit by developing a next generation, framework-compliant IPA media carbon calculator for the UK market. There are considerable lessons to be learned from putting theory into practice and we expect all markets globally to benefit from this.”

Prasad Ghag, Global Media Head, Consumer Healthcare & Anna Kechekmadze, Global Digital Lead, Sanofi: “We started our decarbonization journey beginning of last year through a simple but robust approach to measure- reduce - offset. Addressing the 1st step of ‘measure’ was the most critical part to understand the quantum of challenge. From our numerous tests through multiple solutions to measure carbon - it was clear - we needed an industry benchmark and a set of principles to bring a standardized approach. And that’s where GARM has been so effective in bringing all the parties together - advertisers, platforms, agency partners, sustainability experts - to create that one direction for us all. We at Sanofi CHC are proud to be part of the team in creating this approach, while also learning through the process. This is now our key objective to measure all our digital campaigns’ carbon footprint across the world and leveraging this framework will be key in delivering on this ambition.”

Antoine Ganne, Managing Director, SNPTV: “The GARM framework is a true milestone in the media industry's commitment to a more sustainable advertising model. At SNPTV, we started this journey 2 years ago with our common framework for TV emissions measurement and we couldn't be happier to see our initiative followed and enhanced at an international scale. We thank the GARM for this opportunity to share our work and take part in these exciting discussions. We hope this framework will help all members of our industry to engage in a harmonized monitoring of advertising campaigns.”
