Planet Mobilization

Climate change is one of the greatest challenges of our age. The World Health Organization (WHO) estimates that between 2030 and 2050 climate change will cause an estimated 250,000 additional deaths each year. Sanofi has committed to "Planet Mobilization", a program designed to evaluate and limit direct and indirect impacts of our operations on the environment throughout the lifecycle of our products. From the raw materials we use in our products to their potential end-of-life impact on human health and the environment, we strive to reduce the potentially negative effects of our activities.


Reducing Greenhouse Gas Emissions

In June 2020, Sanofi received approval from the “Science Based Targets initiative” (SBTi) for setting science-based targets to reduce absolute* greenhouse gas (GHG) emissions to limit global warming to 1.5°C - in line with the objective of the 2015 Paris Agreement. All Sanofi employees, as well as partners and suppliers, will be involved in achieving these objectives.

The SBTi is a collaboration between the Carbon Disclosure Project, the United Nations Global Compact, the World Resources Institute, and the World Wide Fund for Nature.

*An absolute target refers to a target defined by a reduction in total emissions over time and not relative to a measurement of business activity.

Committed to 100% Renewable Electricity

In September 2020, Sanofi joined the RE100 initiative to source 100% renewable electricity across all its global operations by 2030. Promoting the use of renewable energies and reducing its greenhouse gas emissions are part of the company’s strategy towards its overall goal of carbon neutrality (net zero CO2 emissions related to our activities) by 2050.

The RE100 initiative  brings together hundreds of large and ambitious businesses committed to 100% renewable electricity with the mission of accelerating a global shift to clean energy. 

Sanofi is reaffirming its position in the Leadership Group by obtaining the maximum A score in Water Security and A-score in Climate Change

Committed to a healthy planet

In December 2020, Sanofi got notification of the maximum A score to the CDP Water Security questionnaire, rewarding its increased efforts on water stewardship.
At the same time, we obtained an A- score to the 2020 CDP Climate questionnaire for our actions to mitigate climate change, and for transparency in our reporting practices.
These scores place our Company on the CDP’s prestigious “A List” and in the CDP’s Leadership Group, which means that Sanofi is leading the way to a more sustainable future. 

Planet Mobilization

Sanofi’s environmental strategy for 2015-2025 is embodied in Planet Mobilization, covering the company’s entire value chain and involves all our stakeholders.

Reducing greenhouse gas emissions

We have a responsibility to reduce our carbon footprint. Energy is one of the company’s primary sources of greenhouse gas emissions. We endeavor to optimize energy consumption across all the company’s businesses by adopting a responsible approach to energy, as well as a responsible transportation policy for both goods and people. We are committed to use less, use better and use greener.

  • By end 2019, greenhouse gas emissions linked to energy were down by 12% compared to 2015
  • About 50 sites have obtained ISO (International Organization for Standardization) Energy or Environment certification. Our four main administrative sites are certified HQE (High Environmental Quality). We encourage employees to use electric cars, public transportation and carpool
  • Sea transportation is favored over air shipments whenever possible 

Streamlining water consumption

With the growing scarcity of water resources, Sanofi strives to constantly reduce the water consumption of each of its activities. In 2019, our water consumption decreased by 19% compared to 2015.

Since 2014, Sanofi has put in place procedures to identify the sites most at risk with respect to water consumption. Any site located in a zone of major water stress must conduct a suitable study and define an action plan with objectives and a follow-up.

Managing pharmaceuticals in the environment

We also pay special attention to how we manage pharmaceuticals in the environment.

Pharmaceuticals can impact the environment through several sources: industrial wastewater, drugs used and excreted by patients, and insufficient disposal methods of unused or expired medication.

We have implemented a new strategic approach that covers the entire life cycle of our medicines, from production to their use by patients. It encompasses several initiatives:

  • Evaluating and minimizing emissions to the environment from manufacturing
  • Assessing the environmental impacts related to use of our products
  • Encouraging the proper use and proper disposal of medicines
  • Advancing scientific research by collaborating with other stakeholders

Waste Management

For waste management, Sanofi has put in place specific procedures. We identify, organize, collect, sort, process, store, transport and dispose of different types of waste in accordance with local regulations.

Our goal is to significantly reduce waste production through the 3Rs - Reuse, Recycle and Recover.

In 2019, the quantity of waste has decreased by 15% compared to 2015 and 75% of this waste is recycled.

The Planet Mobilization program highlights robust initiatives around waste:

  • Optimizing solvent use for better waste management
  • Making the best use of blister packaging materials
  • Supporting take-back programs to collect unused medicines
  • And actions to combat food waste


According to the Planet Mobilization Program 2015-2025, we have a global commitment to manage the biodiversity of our sites. The first step was to perform a sensitivity analysis of all our non-urban sites. This identified a list of priority sites that required further assessment, and potentially risk management plans. 

Climate change and health

Climate change has direct health impacts as it can lead to extreme weather phenomena, heatwaves or extreme cold, food shortages, difficulties in accessing drinking water and increased air-pollution.

Climate change also induces indirect effects such as creating favorable conditions for the intensification and spread of vector-borne diseases or increasing the allergenicity of pollens.

Sanofi contributes to addressing climate change impacts on health through the following actions, involving various internal stakeholders:

  • Continuing R&D efforts for some climate-sensitive diseases like sleeping sickness or malaria
  • Leveraging our portfolio and actively working with organizations and institutions to provide medicines to patients affected by some diseases influenced by modified climate conditions, such as malaria, sleeping sickness and leishmaniasis
  • Supporting communities affected by crises related to climate change through emergency assistance efforts led by Sanofi Espoir Foundation, Sanofi US and Sanofi CARES North America
  • Raising awareness among our stakeholders, such as employees, healthcare professionals, and patients
