Sustainability
We are at the forefront of addressing some of the world's most critical challenges, striving to create a healthier, more resilient future. We're minimizing the environmental impact of our products and activities across our value chain while adapting our business to environmental changes and strengthening the resilience of healthcare systems.
Peoples' health and the environment are inextricably linked. At Sanofi, our dedication to improving people's lives goes beyond developing life-changing medicines and vaccines: it encompasses our contribution to the environment and society. We've set clear goals and are employees and partners to join us in taking action for the planet.
Collective action is needed
Government and policymakers
Make decarbonisation a priority, e.g., through preventative
care, investing in innovation to reduce environmental impact
and healthcare professional education1
Healthcare professionals
Conduct virtual consultations where possible to lower travel and reduce emissions, work with patients to manage conditions and reduce complications (which can lead to increased carbon emissions)1,2
Patients
Be empowered to explore and align on ‘greener’ care options with healthcare professionals1
Pharma, biopharma, and med-tech
Reduce carbon emissions and environmental impacts associated with development, manufacturing, supply, and product lifecycle1
How Sanofi is building a sustainable environment
Recognising our responsibility, our global actions include the following priority areas:
Achieve carbon neutrality by 2030 and net zero emissions by 2045
Reduce Greenhouse Gas (GHG) emissions
Source renewable electricity
Foster an eco-fleet
Limit environmental footprint and adopt circular solutions
Preserve natural resources
Reduce environmental footprint
Protect and foster biodiversity on sites
Improve environmental profile of products
Our Eco-design approach embeds environmental sustainability at every stage of our products' life cycle
From 2025, all new medicines and vaccines adopt this approach, extending to our 20 top-selling products by 2030
Our UK goals align with those of Sanofi global and the UN's Sustainable Development Goals
Obtain international standard (ISO) certifications for the management of environmental and energy systems within our Reading office
Reduce indirectly caused (scope 3) emissions by decarbonising our supply chain and reviewing business travel
By 2025, all new medicines & vaccines will adopt an Eco-design approach
Reduce food waste by half in our offices and optimise our heating, ventilation, and air-conditioning operation times
These goals are also aligned with the NHS, the first health service in the world to announce a plan to become a net zero carbon health system by 2045.3 As an NHS supplier, we take our commitment to supporting these goals very seriously.
What we’ve achieved so far in the UK
We reduced our carbon emissions by 49.8% between 2019-24, by:
Consolidating our UK offices
Installing motion sensors and non-occupancy timers to save energy
86% of our Sanofi car fleet are now hybrids
Our headquarters are now entirely powered by renewable energy, are plastic free and all waste is recycled or turned into biofuel
Our UK ‘We Mean Green’ team empowers and educates our Sanofians
Act as internal ambassadors to support the company’s green strategy
Support planning of company events to ensure sustainable practices are in place
Organise awareness days and local activities such as river cleaning, litter picking and recycling schemes.
Sanofi is recognised
Sanofi is recognised as a global leader in sustainability, actively working to reduce our environmental impact. However, we know there is more to be done, and we remain committed to developing and implementing sustainable solutions. In 2024, Sanofi was ranked the 7th most sustainable company by Time magazine and rose to 3rd place on the Access to Medicine Index, up from 8th in 2022.
As a healthcare company, we understand the urgency of addressing climate change. We’re committed to the United Nations’ Race to Zero initiative, taking bold action to mitigate climate change. We aim for net-zero greenhouse gas emissions by 2045 (all scopes), with a trajectory towards carbon neutrality by 2030.
Our strategy focuses on a 90% reduction in emissions across our value chain by 2045 (vs. 2019) while offsetting residual emissions from 2030 through high-impact, community-centered projects, ensuring the highest standards of integrity and impact.
Carbon reduction plan
Minimisation of our environmental impact is underway.
Follow our progress towards achieving net-zero emissions by 2045.
