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).
We document all CO2 emissions from stationary sources (Scope 1), indirect emissions resulting from the generation of the purchased electricity and district heating (Scope 2) and emissions resulting from the use of our products (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, liquefied petroleum 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, it also includes 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. From 2010 to 2017 only the fuel consumption for stationary applications (mostly test stands and emergency generator sets) were taken into account.
As we 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), which constitute the basis for the tracking of our production-related goals, are published without fuel consumption.
Scope 2: We differentiate by time and region in our calculations of the indirect emissions generated by district heating and electricity from external sources. 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 EPA. Since 2016, CO2 emissions have been calculated according to separate assessments for 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 tariffs 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 USA. 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 travels 15,000 kilometers per year for 10 years. For the vans, we set an average annual distance driven of 28,500 kilometers, also for 10 years. At the moment, no statutory test cycles are prescribed to be carried out for trucks and buses. The European Commission has developed a computer-based simulation program (VECTO) that aims to make manufacturers’ statements regarding the fuel consumption and CO2 emissions of trucks and buses comparable. Heavy-duty trucks and buses for long-distance and regional transport produced on or after January 1, 2019 will be the first vehicle segments to be certified using VECTO. We calculate other indirect CO2 emissions due to purchased services and preliminary work for business trips and truck deliveries, which we use as examples.

We do not currently calculate the figures for other greenhouse gases across the Group. As the calculation 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.
