We rely on our global energy management to use resources as efficiently as possible. The basis for this is a global audit of the energy efficiency of our plants and processes. The production of air gases in air separation plants accounts for the greatest share of the Group’s electricity consumption (over 85 percent). This is why we particularly focus on improving energy efficiency and productivity and have set ourselves a global target in this area.

Energy consumption (in million MWh)



















Assured by KPMG


Other energy sources include for example thermal energy, heating oil, biofuel energy, propane, butane, and since 2013 diesel fuel. The increased consumption of other energies in 2011 resulted from the inclusion of additional other energy sources (e.g. naphtha and methanol) into the indicator scope.

As a result of the first-time application of the revised accounting standards, the sites in the scope of our reporting changed in the 2013 financial year. Accordingly, the key financial, environmental and employee KPIs for 2012 were adjusted retrospectively. In addition, the KPIs for employees, occupational health and safety and environmental protection for the year 2012 were retrospectively adjusted to account for the effects of the acquisition of the US homecare company Lincare. To ensure that the figures for 2012 and 2013 can be compared, we reported the full year 2012 for Lincare.

Energy consumption and energy efficiency

Compared to 2012, Linde’s overall energy consumption increased slightly. As a result of changes in accounting standards, joint ventures that had not been included in the key performance indicators in previous years were recognised in 2013. To maintain comparability, the figures for 2012 were adjusted retrospectively. Some of the newly included sites are highly energy-intensive and contributed to an increase in the overall energy needs of the Linde Group in comparison to the years prior to 2012.

227,000 tonnes

of CO2 saved through energy efficiency projects

In 2013, we identified around 300 projects that help us reduce the Group’s energy consumption. By implementing these projects, we achieved cost savings of more than EUR 35 million and saved 227,000 tonnes of CO2. In California, for example, we have been working with energy companies on 16 projects since 2009 to optimise energy use at Linde sites. As a result, we have reduced energy costs at these sites by USD 1.75 million per year.

The production plants operated by Linde Gas Germany have been certified to ISO 50001 since 2012. This global standard is evidence of a systematic approach to energy management with clear assignments of responsibilities, well-defined goals and on-going identification of scope for efficiency gains.

Renewable energy

As an energy-intensive company, Linde depends on access to a reliable and competitively priced energy supply. We are exploring the use of renewable energies, the level of which currently largely reflects the energy mix applicable in different locations across the world. In the UK, we have obtained 100 percent of the electricity we use at all office sites from renewable energy sources since the end of 2013. In Sweden, Linde owns a share of around 9 percent in the wind energy company VindIn. The long-term goal of the initiative is to provide 1 million MWh of electricity. Some 190.000 MWh of electricity were already generated as part of this project in 2013. Linde Healthcare has been obtaining Renewable Energy Certificate System (RECS) certificates since 2009. RECS is an initiative that promotes regenerative energy sources across Europe. In the period under review, 40,000 MWh of the energy we consumed was RECS certified.
