How we calculate and document our CO2 emissions
Daimler calculates and documents its CO2 emissions in accordance with the 2004 Corporate Accounting and Reporting Standard of the Greenhouse Gas Protocol Initiative (Scopes 1 to 3).
Documented are all direct CO2 emissions from our company’s own sources (Scope 1), indirect emissions resulting from the generation of the purchased electricity and district heat (Scope 2), and emissions resulting from the use of our products, from the supply chain, and from recycling (Scope 3). Thus we also take into account the emissions produced before and after our own activities.
Scope 1: We calculate our direct emissions from the combustion of fuels, heating oil, natural gas, liquid gas, and coal with fixed CO2 emission factors as specified by the World Business Council for Sustainable Development (WBCSD) or the German Emissions Trading Office, “DEHSt.” From 2017 on, this calculation has also included the fuel consumption of Daimler’s own vehicles. It takes into account those vehicles whose fuel consumption is recorded using an in-house invoicing system. Vehicles that are not currently recorded by the system are being integrated into the recording by means of location-related queries.
Because we primarily consume fuels for non-production purposes (including company vehicles, test stands), we do not consider the fuels for our production-related goals (energy, CO2). For this reason, the specific energy consumption and CO2 emissions (measured per vehicle produced) that constitute the basis for our production-related targets are published without fuel consumption.
Scope 2: We calculate the indirect emissions of district heating and electricity from external sources, differentiated by time and region. If more detailed data is not available, we use the annually updated factors of the International Energy Agency (IEA). In the United States we use the electricity generation factors published by the Environmental Protection Agency (EPA). Since 2016, accounts of CO2 emissions have been balanced using the separate accounting approaches “market-based” and “location-based” emissions. This calculation is based on the new guideline of the Greenhouse Gas Protocol Initiative for determining Scope 2 emissions, which was published in 2015. For the assessment of “market-based” emissions, we determine the CO2 emission factors of the local electricity rates or power companies at our worldwide locations. Where such information is not available, we continue to use the current average emission factor published by the IEA for the country in question or according to the EPA for the United States. For the sake of comparison, we also publish the CO2 emissions of all our locations according to the “location-based” method, which takes only country-specific emission factors into account.
Scope 3: We calculate the CO2 emissions generated by the use of our products on the basis of our sales figures and the average fleet consumption values. For this calculation, we assume that each car is driven 20,000 kilometers per year for 10 years. Additional indirect CO2 emissions from the supply chain (purchased goods and services) or from the recycling of vehicles are calculated on the basis of vehicle-specific life cycle assessments.
We do not currently calculate the figures for other greenhouse gases across the Group. As the balancing of accounts of climate-relevant coolants in the German plants shows, the emissions from such refrigerants account for only a negligible amount in the parts per thousand range.
