Havas targets having 85% of its direct suppliers (by emissions) aligned with a decarbonisation pathway by end-2026, covering Scope 3 categories 3.1-3.2 (purchased goods, services and capital goods = 56,948 tCO2e combined in 2025). The Group launched a supplier engagement programme in 2025 specifically aimed at SMEs to help them calculate emissions and set targets. All new suppliers must sign the Responsible Purchasing Charter. In 2023-2024, the Group assessed suppliers on environmental commitment covering 85% of direct suppliers by emissions in five main countries. A CSR clause is embedded in all new contracts.

The Havas Carbon Impact Calculator is a proprietary tool deployed across all agencies since end-2023 to measure the carbon footprint of events, media and creative campaigns for clients. It has been used on more than 2,500 projects for over 170 clients. The tool applies local electricity emission factors, uses specific data from Havas' media providers in 60+ countries, and in 2025 began implementing the Global Media Sustainability Framework (GMSF) developed by Ad Net Zero. The tool allows agencies to offer pre-launch carbon reduction alternatives to clients, supporting their Scope 3 downstream transformation.

Employee commuting represents 13,549 tCO2e in 2025 (up 12% vs 2024). In France, Havas has implemented a sustainable mobility allowance of up to €600/year supporting employees choosing low-emission commuting (cycling, walking, public transport). This serves as an alternative to standard public transport reimbursement and encourages greener commuting habits. The Group tracks employee commuting emissions as a Scope 3 category and has committed to reducing operational Scope 3 emissions significantly by 2035.

Havas has developed a Renewable Energy Roadmap targeting 100% renewable electricity by 2030. By 2025, 86% of electricity consumption came from renewable sources (19,355 MWh of 22,521 MWh total). The roadmap uses a decision tree guiding entities through self-consumption (on-site generation), power purchase agreements (PPAs), supply contracts with green electricity providers, and Guarantees of Origin (GOs) or Energy Attribute Certificates (EACs, i-RECs, RECs). In 2025, 21% came from energy supply contracts with GOs and 65% from other purchases (GOs 28%, RECs 21%, i-RECs 16%). Priority countries have been identified based on electricity consumption and emissions impact.

Havas targets 100% renewable electricity across global operations by 2030. In 2025, 86% of electricity was sourced from renewables. The roadmap prioritises the countries with highest energy consumption and offers local teams a decision framework spanning on-site generation, green supply contracts, and — where direct sourcing is not possible — Guarantees of Origin to ensure traceability. Several countries (France, UK, Spain, India) have introduced local renewable measures and obtained ISO 14001 certification.
