The International Energy Agency (IEA) emission factors database is used for the calculation and reporting of the location-based CO2 emissions for electricity, also referred to by the GHG Protocol. Indirect energy conversion results in greenhouse gas emissions (CO2) that are determined by the primary energy used in the country’s electric power generation mix. A shift from the company’s own power generation to purchasing electric power may therefore positively or negatively impact Sika’s total carbon footprint.
To obtain an informed estimate, we use the Greenhouse Gas Protocol calculator to quantify the scope 2 emissions. In some countries, e.g. in Germany and the USA, Sika has contractual agreements with power suppliers to procure electricity from renewable sources, e.g. from hydro-electric conversion or solar suppliers, which has a lower carbon footprint than the average footprint for energy generation in the country. In these cases, Sika deducts the renewable amount from total consumption, before conversion into CO2. For the year under review, the calculated CO2 emissions for the third-party power supply amounted to around 124,000 tons for the Group (previous year: 109,000 tons).
