CO2 Emission Values
Calculation of CO2 Emissions According to EN16258
A multiple-year analysis showed that only EN16258 is suitable as a uniform standard for calculating greenhouse gas emissions for supply chains. This recognized, governmental EU standard, which covers all transportation modes, is consistently implemented by CarbonCare. This makes CarbonCare one of the few global calculators that uniformly and transparently determines all CO2 and CO2 equivalents from transportation (cargo and passenger) and logistics activities. The calculations are based on realistic and regularly measured annual values and enable companies to actively combat climate change by reducing and/or offsetting their harmful emissions.
Calculation of the values for CO2 and CO2e
Primarily, EN16258 calculates the TTW (Tank-To-Wheel) and WTW (Well-to-Wheel). TTW means the direct combustion of energy for the respective mode of transport, whereas WTW includes the production, transportation and distribution of fuel, including the final combustion of energy. WTW is WTT + TTW, where WTT means “Well to Tank” (see also to next graphic).
EN16258 only provides for the calculation of CO2 equivalents: CarbonCare goes one step further. We calculate not only CO2 equivalents, but also the pure CO2. This is of interest to our customers who are most active in logistics, transport and distribution of goods.

CO2 Calculation Methodology
CarbonCare analysed, evaluated and compared all global standards on which the various calculators are based. It was found that most of the standards focus on regional areas or specific transport modes and that the methodology of the EU EN16258 standard is the most appropriate.Methodology >
