Primary: Sustainable procurement: engaging 85% of suppliers in decarbonisation pathways by 2026 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.

Dependent: Carbon Impact Calculator for clients: measuring and reducing campaign carbon footprints 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.

Primary: Employee commuting reduction via sustainable mobility allowance and soft mobility promotion 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.

100% renewable electricity by 2030 via GOs, EACs, PPAs and on-site generation 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.

100% renewable electricity by 2030 via on-site, PPAs, and Guarantees of Origin 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.

Primary: Business travel reduction via global Travel Policy prioritising train and virtual meetings Business travel represents a substantial portion of Havas' GHG emissions (10,401 tCO2e in 2025, down 17% vs 2024). Havas introduced a global Travel Policy in 2025 applicable to all employees, requiring train to be prioritised over air, limiting premium flight classes, encouraging hybrid/electric vehicles for short distances, and promoting hybrid or virtual formats for meetings and seminars. This policy achieved a 17% reduction in business travel emissions on a like-for-like basis.

Dependent: Supplier engagement & Responsible Purchasing Charter Havas aims to involve all suppliers in a decarbonisation strategy aligned with Group commitments by 2026. In 2025 the Group continued data collection on suppliers' climate commitments and launched a dedicated engagement programme for SMEs without reduction targets. An updated Responsible Purchasing Charter must be signed by new suppliers during onboarding. Purchased goods & services (Scope 3.1) represents ~58% of total footprint.

Full disclosure of Scope 3 Purchased Goods & Services In 2025 Havas conducted a detailed review of its 2024 carbon footprint with an external advisor and disclosed Category 3.1 Purchased Goods and Services in full for the first time (previously only partially disclosed at 197 tCO2e). 2024 was restated to 47,266 tCO2e for comparability. Reported 2025 footprint more than doubled vs the 2024 published figure, but like-for-like emissions fell 3%.

Scope expanded to all entities (not just >25 employee entities) From the 2025 disclosure onward, all entities are included in the GHG inventory. Previously (2024 published data) only entities with more than 25 employees were covered. Recalculated 2024 full scope is provided for comparability.

SBTi recommitment; targets to be reassessed post-spin-off Following the spin-off from Vivendi in December 2024, Havas reaffirmed its commitment to SBTi and is reassessing its decarbonization pathway with a new baseline. Existing targets used 2018 base year and will be replaced.
