Air Liquide S.A. is a French multinational company that operates in the industrial gas sector. The company was founded in 1902 and has since grown to become one of the world's leading providers of industrial gases and related services. Air Liquide operates in over 80 countries and has more than 66,000 employees worldwide.

The company's core business is the production and distribution of industrial gases, including oxygen, nitrogen, hydrogen, and helium. These gases are used in a wide range of industries, including healthcare, food processing, electronics, and energy. Air Liquide also provides a range of related services, including gas equipment, engineering, and consulting.

In recent years, Air Liquide has been focusing on decarbonisation and renewable energy. The company has set ambitious targets to reduce its carbon footprint and increase its use of renewable energy sources. In 2020, Air Liquide announced its commitment to achieving carbon neutrality by 2050.

To achieve this goal, the company is investing in a range of decarbonisation technologies, including carbon capture and storage, hydrogen production, and renewable energy. Air Liquide is also working with its customers to help them reduce their carbon footprint by providing low-carbon solutions and services.

One of the ways Air Liquide is reducing its carbon footprint is through the use of corporate power purchase agreements (PPAs). A corporate PPA is a long-term contract between a company and a renewable energy provider. The company agrees to purchase a certain amount of renewable energy from the provider, which helps to reduce its carbon footprint and support the growth of renewable energy.

In 2020, Air Liquide signed a 15-year corporate PPA with a wind farm in Texas. The agreement will provide Air Liquide with 50 MW of renewable energy, which is equivalent to the energy consumption of 15,000 homes. The PPA will help Air Liquide to reduce its carbon footprint by around 70,000 tonnes of CO2 per year.

Air Liquide is also investing in its own renewable energy projects. In 2019, the company announced plans to build a 20 MW electrolyser plant in Canada. The plant will produce hydrogen using renewable energy sources, such as wind and solar power. The hydrogen will be used to supply Air Liquide's customers in the energy, mobility, and industrial sectors.

In addition to its focus on decarbonisation and renewable energy, Air Liquide is also committed to corporate energy efficiency. The company has set a target to reduce its energy consumption by 30% by 2025, compared to its 2015 baseline. To achieve this goal, Air Liquide is implementing a range of energy efficiency measures, such as upgrading its equipment and improving its processes.

Air Liquide's commitment to sustainability is reflected in its inclusion in a number of sustainability indices, such as the Dow Jones Sustainability Index and the FTSE4Good Index. The company has also been recognised for its sustainability reporting, receiving the highest rating from the Global Reporting Initiative.

In conclusion, Air Liquide S.A. is a leading provider of industrial gases and related services, operating in over 80 countries worldwide. The company is committed to decarbonisation and renewable energy, with a target to achieve carbon neutrality by 2050.
