We rely on innovative technologies and energy efficiency measures to conserve resources, reduce greenhouse gases and ensure sustainable business success. We provide our customers with solutions to enable sustainable electricity and fuel value chains – covering everything from solar energy through the use of biological resources to hydrogen as an environmentally friendly fuel or storage medium.
Energy efficiency activities
Our total energy consumption for 2011 amounted to around 57 million MWh (2010: 54 million MWh). The reason for this increase was a rise in production compared with the previous year. Rising production levels is linked with an increase in energy consumption. Our global energy management system helps us counter this trend.

The Linde Group
biofuel energy, methanol, propane and butane.
We regularly conduct internal audits to check the energy efficiency of our plants and processes across the globe. The potential energy savings discovered during the audits are then realised where possible. In 2011, we identified over 450 projects that are enabling us to reduce our energy consumption and CO2 emissions. We expect these initiatives to result in savings of 330,000 MWh and 170,000 tonnes CO2 emissions. All production sites of Linde Gas in Germany were certified in accordance with the energy management standard DIN 16001. The primary goal of this norm is to increase energy efficiency and optimize energy use.
Electricity and natural gas jointly account for about 80 percent of the energy carriers we use. We primarily use these sources to operate our air separation and HyCO plants. As our air separation units account for around 85 percent of our electricity consumption, we are focussing our efforts on improving energy efficiency and productivity in these units. In line with this, we have set ourselves a global goal.
Renewable energy accounts for around 20 percent of our electricity mix, generally reflecting the national electricity mix offer at our sites. The proportion of renewable energy is particularly high, for example, in Norway and Brazil. In some areas, we undertake additional activities aimed at promoting regenerative energies. In Sweden, for example, we are part of a consortium of companies committed to investing in wind energy and improving the enabling infrastructure. Furthermore, Linde Healthcare has been obtaining RECS certificates every year since 2009. The Renewable Energy Certificate System (RECS) is an initiative that promotes regenerative energies across Europe. RECS certificates confirm that energy has been produced in an environmentally friendly way. In 2011, 40,000 MWh of energy that we consumed was RECS-certified.
