Havas UK&I:

Scaling Decarbonisation Across the Business.

Who is Havas UK&I?

Havas UK&I is part of the global Havas communications group and brings together expertise across advertising, media, creative, health, and communications services.

Operating across the United Kingdom and Ireland, Havas UK&I works with a diverse portfolio of clients and is committed to embedding sustainability into its business operations and decision-making.

The Challenge:

Like many large organisations, Havas UK&I faced the challenge of driving meaningful sustainability action with a relatively small sustainability team.

  • Carbon management activities were often centred around annual reporting cycles, requiring significant effort to collect emissions data from internal stakeholders and suppliers.
  • While reporting remained important, the team wanted to shift the focus towards ongoing engagement and tangible emissions reduction.
  • Havas UK&I’s goal was to move beyond sustainability being the responsibility of a small central team and instead create broader ownership across the business, empowering employees to better understand and reduce their emissions impact.

The Goals:

Havas UK&I was looking for a platform and partner that could:

  • Simplify and demystify carbon emissions and decarbonisation.
  • Make sustainability more engaging and accessible for employees across the business.
  • Enable continuous action rather than focusing solely on annual reporting.
  • Provide industry-specific expertise, particularly around emissions associated with media buying and client-related activities.
  • Empower teams to take ownership of their emissions and contribute directly to reduction efforts.

The Solution:

Using the Transition module from 51toCarbonZero, Havas UK&I transformed the way sustainability is managed across the organisation.

  • The platform helped expand sustainability ownership from a small central team to a wider network of employees actively involved in carbon management and decarbonisation initiatives.
  • Teams were able to upload emissions data on a quarterly basis, gain greater visibility into their emissions profile, and receive tailored recommendations to support reduction efforts.
  • By making carbon data more accessible and actionable, employees were empowered to move beyond reporting and play an active role in driving meaningful change.

“The value of 51toCarbonZero is that they really are an extension of your team. We have more minds on the job, and they are incredibly flexible and innovative in helping us understand our decarbonisation journey and make it easier and more engaging for the rest of the company.”

Chief Impact Officer, Havas UK&I

The Results:

Expanded sustainability ownership from a team of two to more than twenty employees actively engaged in carbon management and decarbonisation activities.

Increased employee engagement in sustainability initiatives across the business.

Improved understanding of emissions impacts and reduction opportunities.

Helped bridge the gap between carbon reporting and meaningful action.

For Havas UK&I, this marked an important step in embedding sustainability more deeply across the organisation and creating a culture of shared responsibility for decarbonisation.
