Air quality

Improving air quality for better environment and health

The air is a common, vital and universal good. Its quality is threatened in many parts of the world by unbalanced development, causing public health problems (heart disease, strokes, and respiratory diseases) and exacting a substantial cost, both human and financial, to society.

Air pollutants are multiple: NOx, SOx, particulate matter (PM10, PM2.5), etc. The air pollution is caused in part by the burning of fossil fuels, which also produces carbon dioxide (CO2), a greenhouse gas and a major cause of global warming.

Air Liquide acts responsibly to preserve environment and public health, with the objective of improving air quality and fight against global warming.

The Group works through its operations, with its R&D and technology teams and by relying on a network of international experts in the fields of industry, transportation and energy:

In industry

Thanks to the numerous applications of its products, the Group helps to develop cleaner manufacturing. Its capacity for industrial integration leads to synergies that promote energy and raw material savings and that reduce emissions of pollutants and greenhouse gas effects.

In transportation

By producing the hydrogen that is used for fuel desulfurization and by developing clean transportation solutions around biomethane and hydrogen energy.

In its operations: energy consumption and emissions

Via its energy purchases, the Group encourages the supply of low carbon electrical energy. Air Liquide also supports the development of renewable energy.

By paying attention to the environmental impact, particularly on the air and climate change, of its operations related to production and transportation.
