Sustainable development

We strive to contribute to a more sustainable world

Grow with reduced carbon intensity

Energy efficiency is a key focus of the Group’s World Business Lines and activities, which constantly strive to minimize the energy and environmental footprint of its products and services.

This optimization is a combined result of:

  • Technological solutions proposed by Air Liquide in its production process
  • Scale effects, co-production and synergies, in particular through the development of its pipeline network
  • The operational optimization of its production units
  • The solutions chosen in terms of energy and commodities supplies

Energy efficiency in production units

The energy efficiency of oxygen units improved in 2015, in particular thanks to the commissioning of new production units.

The energy efficiency of our hydrogen units temporarily decreased in 2015, in particular due to the gradual commissioning of the large hydrogen unit in Yanbu, Saudi Arabia which has not yet reached optimal efficiency.

Transportation and efficiency of truck deliveries

87% of all gas deliveries are made via pipeline or through units on customer sites. As a result, only 13% of air gases or hydrogen are transported by truck.

Between 2011 and 2015, thanks to the success of programs to optimize deliveries, the efficiency of industrial gases transportation continued to improve.
