The aim of this expert notification is to
- notify an incorrect data interface on battery density in a previous version leading to overestimate the GHG emissions of electric vehicle production (BEV and PHEV) and
- revisit the most common misunderstandings or misinterpretations, in order to rectify incorrect claims, made in (social) media.
The goal of the Life Cycle Assessment (LCA) was to estimate the greenhouse gas emissions and the primary energy demand of the 61 vehicles previously assessed and documented by Green NCAP, using their intensive laboratory and real-world test procedures (e.g. fuel/electricity consumption under different test and ambient conditions). The vehicles with an ICE (Internal Combustion Engine) are tested with petrol E10 and diesel B7. The Life Cycle Assessment was done for generic global supply chains of vehicle production and energy supply in Europe between 2021 and 2037. The lifetime millage of the vehicles was set to 240,000 km in 16 years.
The main focus is to estimate significant differences between the vehicles and its main influencing parameters of propulsion system, fuel, energy consumption, vehicle weight, battery capacity, CH4- and N2O- emissions from vehicles equipped with an ICE.
The methodology and data used for the LCA are documented by JOANNEUM RESEARCH and the documentation is available on the Green NCAP webpage. “Estimated Greenhouse Gas Emissions and Primary Energy Demand of Passenger Vehicles Tested in Green NCAP: Life Cycle Assessment: Methodology and Data”.
