London: Havas UK&I has announced a strategic partnership with 51toCarbonZero (51-0), a climate technology platform tailored for the advertising and media industries, to strengthen its sustainability transformation and carbon reporting processes. The move signals Havas’ commitment to deepening emissions transparency, particularly in scope 3, and progressing meaningfully toward its climate goals aligned with the Paris Agreement.
Under the partnership, Havas UK&I will adopt 51-0’s advanced platform to automate and centralise emissions data, shifting from annual to rolling measurement cycles. This will provide real-time insights, support faster decision-making, and embed climate data into everyday operations across departments.

“Partnering with 51-0 gives us the specialist tools and expertise we need to take our decarbonisation programme to the next level,” said Rosie Kitson, Chief Impact Officer, Havas UK&I. “51-0’s experience in media and advertising, particularly around scope 3 emissions and media supply chains, is second to none. We’re excited to make our data work harder, drive more targeted actions, and ensure sustainability becomes something everyone in our business can own.”
Havas selected 51-0 for its intuitive data visualisation, operational usability, and advanced scope 3 emissions capabilities—factors essential to embedding sustainability into procurement, capital allocation, and campaign operations.

Richard Davis, CEO and Co-founder, 51toCarbonZero, added, “Havas UK&I is making a bold and credible move by consolidating its carbon measurement approach and empowering its teams with real-time insight. As agencies look to meet science-based targets, faster and more meaningful scope 3 visibility is essential. We’re proud to partner with Havas UK&I to help embed sustainability deeper into its day-to-day marketing operations and deliver lasting impact.”
The collaboration supports Havas UK&I’s Science Based Targets initiative (SBTi), which includes a 71% reduction in scope 1 and 2 emissions by 2035 and a 43% reduction in operational emissions. This initiative forms a critical part of Havas’ broader environmental strategy to lead sustainable change in the media and advertising industry.
