CO2 is a consequence of fossil energy consumption, and can only be limited within Sika by increasing energy efficiency. This is why Sika controls its CO2 emissions via its energy target and has not set a specific reduction target at Group level.

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 2016, CO2 emissions from the use of primary energy sources ran to around 45,000 tons (previous year: 53,000 tons). Two factories in China still rely on locally sourced coal as a fuel. Overall, however, coal consumption was cut by approximately 50%. Coal has a low gross calorific value and entails higher CO2 emissions than natural gas. Emissions were reduced at two plants by adjusting the product mix, partially replacing a coal-intensive process with a coal-free process.

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 2016, CO2 emissions caused by electricity consumption were calculated at 109,000 tons (2015: 107,000 tons), i.e., more than twice as high as direct CO2 emissions. Leased vehicles and business travel caused additional CO2 emissions of 20,000 and 13,800 tons, respectively (2015: 21,000 and 13,800 tons). Sika’s total CO2 emissions run to around 187,000 tons.
