Sika used 1’779 terajoule (TJ) of energy (pervious year: 1’833 TJ), 44% directly from non-renewable primary energy conversion and 56% from purchased electricity. The fuel types used for direct energy (778TJ) are light liquid fuels (44%), coal (3%) in China, and natural gas (53%).

Energy is a necessary input for conversion processes, e.g. stirring and mixing, melting and cooling, ventilation and pumping, as well as heating and air conditioning of buildings. As mentioned above Sika uses around 44 % of total energy consumption from its own energy conversion, mainly for heating buildings and production equipment, steam generation, drying processes, etc.

Sika’s production itself is less energy-intensive than the supplier industries, specifically the chemical industry. However, Sika believes that energy efficiency and mitigation of emissions are major drivers of its overall efficiency effort. Energy is further a relevant cost factor for Sika.

Therefore, the company has set a target at Group level for energy consumption to achieve efficiency gains of 3% each year in relation to production volumes. Some of our subsidiaries have started energy efficiency programs according to ISO 50001.

Additional information on leased vehicles and travel

In addition, the leased car fleet consumed 288 TJ (302 TJ in 2015) of energy and business travel amounted again to 202 TJ (202 TJ in2015). The leased car fleet figure is derived from the fuel consumption rate of a sample of 65% of the leasing contracts, and extrapolated to 100%. The figure for business travel is derived from a sample of 40% of the travel contracts, and extrapolated to 100%.
