Sanofi is a French multinational pharmaceutical company that operates in the large pharma sector. It is one of the world's largest pharmaceutical companies, with a presence in over 100 countries worldwide. Sanofi is committed to sustainability and has made significant strides in reducing its carbon footprint through decarbonisation, corporate energy, corporate power purchase agreements (PPAs), and renewable energy.

Decarbonisation is a key focus for Sanofi, as the company recognizes the importance of reducing its carbon footprint to mitigate the impact of climate change. The company has set a goal to reduce its carbon emissions by 30% by 2025, compared to its 2015 baseline. To achieve this goal, Sanofi has implemented a number of initiatives, including energy efficiency measures, the use of renewable energy, and the optimization of its supply chain.

One of the ways Sanofi is reducing its carbon footprint is through the use of renewable energy. The company has invested in renewable energy projects, such as wind and solar, to power its operations. Sanofi has also implemented energy efficiency measures, such as the use of LED lighting and the optimization of its heating, ventilation, and air conditioning (HVAC) systems, to reduce its energy consumption.

In addition to using renewable energy, Sanofi has also entered into corporate power purchase agreements (PPAs) to support the development of renewable energy projects. PPAs are long-term contracts between a company and a renewable energy provider, where the company agrees to purchase a certain amount of renewable energy at a fixed price. Sanofi has entered into several PPAs to support the development of wind and solar projects, which not only helps to reduce the company's carbon footprint but also supports the growth of the renewable energy industry.

Sanofi is also committed to reducing its energy consumption through corporate energy initiatives. The company has implemented an energy management system to monitor and optimize its energy usage, and has set energy reduction targets for its facilities. Sanofi has also implemented a program to promote energy efficiency among its employees, encouraging them to adopt sustainable practices at work and at home.

Sanofi's commitment to sustainability extends beyond its own operations. The company is also working to reduce the environmental impact of its supply chain. Sanofi has implemented a supplier sustainability program, which requires its suppliers to adhere to strict environmental and social standards. The company also works with its suppliers to identify opportunities for energy efficiency and the use of renewable energy.

In conclusion, Sanofi is a leader in sustainability in the large pharma sector. The company is committed to reducing its carbon footprint through decarbonisation, corporate energy, corporate PPAs, and renewable energy. Sanofi's efforts to reduce its environmental impact extend beyond its own operations, and the company is working to promote sustainability throughout its supply chain. Sanofi's commitment to sustainability not only helps to mitigate the impact of climate change but also supports the growth of the renewable energy industry.
