Safety and Health

The number of occupational accidents leading to lost work time of more than one day showed a year-on year decrease of 8.4%. In 2017, 8.7 occupational accidents per 1,000 employees were recorded (previous year: 9.5). In 2017, injuries again caused absences of an average of around 22 days (previous year: 22). This figure was strongly influenced by longer absences due to injuries to the system caused by accidents while walking. In the US, the comprehensive safety concept, which was launched in 2015 under the name “Sika Safe”, led again to a significant reduction in accident numbers in 2017 resulting in approximately 70% less accidents per 1,000 employees over the past two years.

Energy Efficiency

In 2017 Sika consumed 1,961 terajoules of energy (previous year: 1,779 terajoules). Approximately 55% of Sika’s energy requirements were met by electrical power from the local grid. The remaining demand was mainly covered by natural gas and liquid fuels. Energy consumption per ton sold added up to 450 megajoules (previous year: 428 megajoules). This increase is mainly due to acquisitions of factories with very energy-intensive production processes (resulting in plus 2.5% of total energy consumption in comparison to last year, adjusted for acquisitions).

It is part of the integration process to reviewand analyze the impact performance, such as energy consumption, of newly acquired sites. This will consequently initiate local improvement projects to align with Sika expectations and targets. These improvements not only need time but also investments on shop floor level. However, overall energy consumption reduced by 17% (target 12%) from 2013 to 2017 from 541 MJ/t to 450 MJ/t which is an average of 4.25% per year.

CO₂-Ausstoss (Scope 1)
CO₂-Emissions (Direct)

CO2 emissions from energy consumed directly by all Sika operating companies and units, both industrial and nonindustrial sites, and by its own vehicles are calculated based on the reported fuel quantities. In 2017, CO2 emissions from the use of primary energy sources ran to around 53,000 tons (previous year: 45,000 tons). Two factories in China still rely on locally sourced coal as fuel. However overall, coal consumption was cut by approximately 50%. Coal has a low gross calorific value and entails higher CO2 emissions than naturalgas. Emissions were reduced at two plants by adjusting the product mix, partially replacing a coal-intensive process with acoal-free process.

CO₂-Ausstoss (Scope 2)
CO₂-Emissions (Indirect)

CO2 emissions from indirect energy consumption, i.e., emissions not due to Sika’s own primary energy usage, including leased vehicles and business travel, are derived from the reported energy quantities. CO2 emissions caused by purchased electricity are calculated using current emission factors from the Greenhouse Gas protocol (GHG), applying average values for electric power production in each particular country. In 2017, CO2 emissions caused by electricity consumption were calculated at 102,000 tons (previous year: 109,000 tons), i.e. approximately twice as high as direct CO2 emissions. Leased vehicles and business travel caused additional CO2 emissions of 22,000 and 16,000 tons respectively (previous year: 20,000 and 13,800 tons).

Use of Water

In 2017 Sika used approximately 1.4 million cubic meters of water (previous year: 1.3 million cubic meters). The water consumption per ton sold was around 0.32 cubic meters (previous year: 0.32 cubic meters). From 2016 to 2017 there was no change in the water consumption. However overall, the water consumption was significantlyreduced by 52% (target 12%) from 2013 to 2017 from 0.67 m3/t to 0.32 m3/t, which is an average of 13% per year.


With an increased production volume, the company generated some 80,000 tons of waste (previous year: 74,000 tons). This corresponds to 18.4 kilograms of waste per ton sold (previous year: 17.8 kilograms per ton sold) or an increase of 3.4%. This significant increase is mainly due to newly enforced regulations in Pennsylvania, USA, in regard to the discharge of sewage water. This has an impact of more than 8% of the total generated waste. As a consequence Sika is in the process of designing its own, local waste water treatment station in order to reduce the main amount of waste and to recycle regenerated water for its production processes.
