This year’s fifth annual Campaign Ad Net Zero Awards showed that reducing carbon emissions delivers commercial performance in both efficiency and effectiveness, wherever you sit in the supply chain.
A special thank you goes to AOP for sponsoring this year’s awards, and to our supporting partners, the Advertising Association, AdGreen, IPA and ISBA, whose contributions ensured the continuation of the awards.
With two new categories this year, Marketing and Sustainability Collaboration and The Business Case for Better, the awards reflected the breadth of work happening across agencies, brands, media owners and technology partners, with household names including The Guardian, Renault Group, Tesco, Spotify and EDF securing wins on the day.
Philippa Forrester hosted the afternoon, with Campaign’s Editor-in-Chief, Gideon Spanier, opening the event.
The awards were judged by a jury of 48 experts from across the advertising sector and beyond, co-chaired by Seb Munden and Alessandra Bellini, and once again guests enjoyed a 100% vegan menu.
What this year’s winners tell us
Before the awards were presented, Seb Munden CBE, Chair of Ad Net Zero, and Elle Chartres, Ad Net Zero Programme Director, shared insights from our analysis of all 28 category-winning entries, testing the room with an interactive quiz on the data behind the work.
The takeaway was clear: decarbonisation is no longer a side project or an added cost. Every winner embedded at least one of the five Actions in the Ad Net Zero Action Plan, and 57% integrated three or more, connecting business operations with media efficiency and creative messaging. Media planning and buying (Action 3) featured in more than 71% of winning entries, while 68% included customer-facing messages encouraging more sustainable behaviours (Action 5).
Elle also pointed to our ongoing research with Kantar, which shows that when brands authentically reflect sustainable behaviours in mainstream creative, emotional engagement goes up and brand equity grows, and to initiatives such as Every Brief Counts that help creative teams do this every day.

Spotlight on our Grand Prix winners
Renault Group, with OMD, OM Sustainable Solutions, Publicis and I Care, took home the International Grand Prix for its Sustainable Media System, which also won the new Marketing and Sustainability Collaboration award.
The judges praised it as “a great example of driving demonstrable action at scale”, with one noting that by anchoring accountability at group level, Renault Group is setting “a formidable standard for how major advertisers should manage their Scope 3 impact”.
Renault Group’s Branding Office and Group Sustainability leadership set a global ambition to reduce creation and media-related emissions by 5% a year. Since 2023, the programme has analysed around 400 campaigns and 294.6 billion impressions, with partners aligned across 23 markets. Between Q1 2025 and Q1 2026, media emissions across its G10 markets fell by 13%, and technical optimisation tests with six publishers in four countries achieved CO₂e reductions of up to 80%.
What makes the work replicable is the way it builds measurement into everyday decisions. A co-created Responsible Media Guidebook gives teams more than 30 practical levers and checklists: the kind of consistent, cross-market approach that Action 3 and the Global Media Sustainability Framework are designed to support.
For the UK Grand Prix, The Guardian won for its long-term approach to climate action, also taking the Best Progress / Long-Term Change award.
The judges described its entry as a “robust and holistic strategy” with real societal reach, combining emissions cuts, fossil-fuel advertising restrictions, climate literacy and wider industry collaboration.
The Guardian has cut its absolute emissions by 48% in five years, verified without offsets and tracked against a 67% target. Its 2015 fossil-fuel divestment and first-in-industry ban on fossil-fuel advertising have helped set a benchmark others have followed. It has published more than 6,000 environment pieces, holds a B Corp score of 100.9, far above the median of 50.9, and created the world’s first carbon-literate sales team, which is now training agency partners.
By making environmental responsibility a core business priority, The Guardian shows how a media owner can align the way it operates with the values it champions, and strengthen audience trust in the process.
