Climate change is one of the biggest challenges to the resilience of health systems and is becoming widely recognized as the greatest threat to human health. Sanofi cares for the planet and human health by strengthening its resilience to environmental changes, including mitigating its dependencies on natural resources and minimizing the environmental impact of its products and activities, aligned to its Planet Care roadmap.
Sanofi’s strategy embraces a holistic approach to climate issues, moving towards net zero greenhouse gas (GHG) emissions by 2045 with intermediate targets by 2030 and by integrating environmental stewardship into every facet of its operations, under the conditions indicated below.
Our Ambition
In 2023, Sanofi's corporate science-based targets were reviewed and validated by the SBTi's Target Validation Team. The assessment confirmed that both the 2030 Scope 1 & 2 target and the 2045 Net Zero target align with a 1.5°C trajectory, while the Scope 3 target meets the minimum ambition required under the 2°C pathway.
Following the divestment of Opella in 2025, which resulted in a change in scope, we initiated the process of resubmitting our SBTi targets for recalculation and revalidation in 2026, in accordance with the most up-to-date applicable criteria at the time of resubmission.
Validation of our objectives by the Science Based Target initiative (SBTi) is a confirmation of the scientific basis of our objectives, as part of the planet-wide efforts needed to limit global warming.
Sanofi main GHG reduction targets versus the 2019 baseline are described below:
- reducing our scope 1 and 2 greenhouse gas emissions by 55% in absolute terms by 2030, versus a 2019 baseline (near-term target);
- reducing our scope 3 emissions by 30% in absolute terms by 2030, versus a 2019 baseline (near-term target); and
- reducing our scope 1, 2 and 3 emissions by 90% between 2019 and 2045 as part of Net Zero target.
Additional supporting goals include:
- Increasing our annual supply of renewably sourced electricity from 11% in 2019 to 80% in 2025 and 100% in 2030 as part of RE100 initiative;
- Moving to 80% of sales fleet meeting Sanofi’s low carbon requirements by 2030, by using lower emission alternatives (hybrid, electric and biofuel vehicles);
- Investing in community-based projects that combine a positive impact on both communities and the environment to mitigate the impact on climate of residual emissions from 2030, on top of a science-based emission reduction trajectory.
Our 2025 Performance
- 49% decrease in scopes 1 and 2 GHG emissions (vs the 2019 baseline).
- 14% decrease in scope 3 GHG emissions (vs the 2019 baseline).
- 86% renewable electricity sourcing (vs 16% in 2019).
- Sanofi’s efforts to fight climate change are evaluated annually by CDP and achieved an A score.
- 60% of Sanofi’s fleet meets the low carbon fleet criteria by using lower emission alternatives (hybrid, electric and biofuel vehicles).
All figures refer to our 2023 SBTi-validated targets, under transition plan perimeter.
Action on Climate Change - Reducing Scope 1 & 2 GHG Emissions
- Energy reduction and efficiency: Energy saving programs are in place at all relevant sites.
- Sanofi's Energy efficiency program is driven by a global management system that covers all relevant operations; it includes a reference framework, an internal audit and performance review program.
- The Energy management system is assessed and certified as meeting the requirements of ISO 50001:2018 for the following activities: research, development, manufacturing, distribution centres and related support functions. This certification covers more than 80% of Sanofi’s energy consumption.
- The Energy programme aimed to reduce energy consumption by 15% in existing facilities by 2025 compared to 2021. – this target has been achieved end 2025.
- Energy decarbonization:
- Sanofi is a member of the RE100 initiative and is committed to delivering 100% renewable electricity by 2030 with the:
-
- Sourcing of RE100 compliant renewable electricity at all relevant sites
- Installation of solar panels; Sanofi can self generates up to 25 GWh per year.
-
- Transition to renewable thermal energy to meet heating needs by increasing the use of biomethane and biomass. A long-term biomethane supply contract (2024-2030) has been signed in France for 210 GWh per year.
- Sanofi is a member of the RE100 initiative and is committed to delivering 100% renewable electricity by 2030 with the:
- Refrigerant gas control, including replacing existing refrigerant gases with lower global warming potential alternatives and improving leak detection and prevention.
- Reducing the climate impact of our sales fleet through vehicle efficiency standards and transitioning to a low carbon fleet (moving to 80%) by 2030 targeting lower emission alternatives (hybrid, electric and biofuel vehicles).
Action on Climate Change - Reducing Scope 3 GHG Emissions
Scope 3 emissions in transition plan account for 92% of Sanofi's total emissions, originating mostly from the purchase of raw materials and subcontracting, making them the primary lever for decarbonization.
- Decarbonization of inputs and raw materials: Sanofi is seeking to replace the most carbon-intensive raw materials with more alternatives with lower environmental impacts or by identifying less carbon-intensive suppliers. Furthermore, our eco-design program makes it possible to identify levers for the decarbonization of activities and products. Eco-design is a systemic approach that aims to integrate environmental criteria from the design stage of a product, but also into its continuous improvement processes.
- Supplier engagement: We are engaging with suppliers to support their work towards improving their environmental footprint and fighting climate change. In 2025, 130 suppliers engaged in the Supplier Engagement Program, covering 60% of supplier-related emissions and representing 50% of our procurement spend. Moreover, through the Energize Program, a collaborative effort within the pharmaceutical industry, we help our shared supply chains convert to renewable energy.
- In 2023, the Sanofi CEO signed an Open Letter to Suppliers published by members of the Sustainable Markets Initiative Health Systems Task Force to set out minimum targets for supplier decarbonization. We are also actively involved in multiple SMI peer collaboration workstreams for supply chain decarbonization through bio-based materials, green heat, etc.
- Other value chain initiatives: Additionally, Sanofi is implementing comprehensive measures to reduce value chain emissions across multiple areas such as optimizing distribution networks, shifting from air to sea freight for product transport, reducing business air travel and reducing operational waste.
Action on Climate Change - community-based program
While our priority is first to avoid and reduce emissions across our value chain to the greatest extent possible; we recognize that some emissions cannot yet be further reduced. By 2045, we aim to limit these residual emissions to less than 10% of our 2019 baseline, in line with our SBTi Net Zero commitment.
That’s where our community-focused program comes in. From 2030 onwards, we aim to mitigate our remaining emissions’ impact on climate, with the objective that the volume of emissions reduced or sequestered by our projects matches our residual emissions.
Since 2022, we’re supporting nine long term projects (up to 21 years) in Kenya, Mozambique, Nepal, Uganda and India - such as mangrove restoration, agroforestry, efficient cooking and water access initiatives - that will not only remove or avoid carbon emissions but also deliver benefits where they are needed most. This program reflects the urgent need for evidence-based interventions that improve water access, reduce indoor air pollution and strengthen resilience to climate-related health threats, supporting nature and community health.
These projects will be certified for their carbon avoidance and sequestration potential, and for related co-benefits under international certification standards (i.e. Gold Standard, VCS by Verra, CCB..).
