Air Liquide's commitment
As part of its global approach to climate, Air Liquide sets the most ambitious objectives of its sector.
Reduce by 30% the carbon intensity of our activities by 2025 vs 2015.
To reduce by 30% the carbon intensity by 2025, Air Liquide is committed to:
85% of all gas deliveries are made via pipeline or through units on customer sites. As a result, only 15% of air gases or hydrogen are transported by truck.
Between 2013 and 2017, thanks to the success of programs to optimize deliveries, the efficiency of industrial gases transportation continued to improve.

* In kilometers per delivered ton livrée for the Industrial Merchant activity, using a base of 100 in 2007.
** Excluding Airgas.
Act for a clean industry.
With its customers, the Group is also committed to a sustainable industry. Thanks to its in-depth knowledge of essential small molecules (oxygen, hydrogen, CO2...) and customers’ processes, Air Liquide is offering technologies which allow its customers to improve the energy efficiency of their industrial processes and reduce their emissions. The Group is permanently innovating to offer new low-carbon solutions. Below are four examples in this domain.
HEATOX™ is an innovative technology which makes the oxycombustion process even more efficient. It consists of extracting heat from combustion fumes in order to heat oxygen and fuel, thus improving the performance of the process by 10%. Compared to air combustion, this technology provides up to 50% energy savings and up to 50% CO2 emission reduction. Moreover, these oxycombustion technologies reduce the nitrogen oxide emissions of glass furnaces by 60% to 95%. So far, this technology has been implemented in several glass production factories in Europe owned by leaders in the sector. It is of particular interest for the Chinese market which represents about 50% of worldwide glass production. Therefore, the Group contributes to the improvement of air quality by enabling its customers in the glass industry to lower their nitrogen oxide emissions while increasing their energy efficiency.
enScribe™, the new range of advanced etching materials in Electronics, has a greenhouse effect 8 times lower than that of conventional etching gases. Its use, for a single customer, has already enabled to reduce by 1% the global emissions of the semiconductor industry.
The Cryocap™ process is a groundbreaking technological innovation which captures CO2 using a cryogenic process (very low temperatures). Cryocap™ can be used in several industries: steel production, thermal power plants, hydrogen production plants.
The partnership between Air Liquide and US start-up Solidia Technologies developed and marketed a “sustainable concrete”. The Solidia process replaces water with carbon dioxide (CO2) in order to harden concrete. This new generation of cement enables the whole industrial chain to reduce the environmental footprint of the pre-cast concrete by up to 70%. This breakthrough technology also reduces the hardening time of the concrete to less than 24 hours and the required amount of water. In addition to capturing large quantities of CO2, the quality of the concrete achieved is greatly improved. Air Liquide will supply the new carbon dioxide injection equipment for production of the Solidia Concrete™ and will be the benchmark global supplier of the gas used in the patented processes of Solidia Technologies.
Avoided CO2 emissions in 2017
Contribute to the development of a new low carbon society.
With ecosystems, via an active dialogue with key players (public policymakers, industrial partners, NGOs, etc.), Air Liquide is contributing to the development of a low carbon society by:
Hydrogen is one of the solutions that offer a response to the challenges of clean transportation: reducing greenhouse gases, pollution in our cities and dependency on oil-based fuels. Used in the fuel cell, hydrogen combines with oxygen from the air to produce electricity, with water as the only by-product. Hydrogen can be produced from renewable energy sources. Hydrogen thus has great potential to provide clean energy and be an alternative to fossil fuels. Hydrogen energy is a fast-growing field of which the Group masters the entire industrial chain (from production and storage to distribution and uses for the end user) and is also actively involved in setting up this industry.
Blue Hydrogen is an Air Liquide initiative that aims to gradually lower the carbon content of its hydrogen production dedicated to energy applications. 95% of the hydrogen that the Group produces is currently from natural gas. Air Liquide is committing to increasing by 2020 the percentage of hydrogen produced for these applications from carbon-free processes, i.e. sources that emit no CO2. The Group’s objective is to produce at least 50% of the hydrogen required by hydrogen energy applications from carbon-free energy sources, by combining:
On January 17, 2017 in Davos, Switzerland, 13 leaders from energy, transport, and industry sectors launched a global initiative in order to share their vision and ambition for hydrogen as an accelerator of the energy transition and to meet climate change targets. During this launch, the members of the Hydrogen Council, of which Air Liquide is a founding member, demonstrated their desire to intensify their investments in the development of the market of hydrogen and fuel cells. By the end of 2018, the Hydrogen Council brings together more than 50 world scale companies.
Approximately 100 million euros of innovation expenses (nearly one third of the total amount) are dedicated every year to reduce the CO2 emissions of our products and those of our customers.
Nearly 40% of our investment decisions address environmental and climate challenges.
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.
Air Liquide acts responsibly to preserve environment and public health, with the objective of improving air quality and fight against global warming.
In 2015, the hydrogen supplied by Air Liquide to refineries (nearly two thirds of the quantity sold by Air Liquide) avoided discharging 1.2 million tons of sulfur oxides into the atmosphere which is nearly four times as much as the total sulfur oxide emissions of a country like France.
Sulfur oxides can cause respiratory problems in humans. Not only are they responsible for the emergence of urban smog but also for acid rains, which cause deforestation and the acidification of water. Moreover, sulfur quickly deteriorates the performance of catalytic converters of vehicles and their capacity to filter fine particles.
