¹ All results are estimates and may vary depending on all assumed parameters (in particular, without limitation, Length, Width, Courses, Bitumen content in asphalt, Burner Fuel type, distances and used machines). Our estimates are based on a model-based scenario analysis performed internally at the WIRTGEN GROUP that has not been independently verified. For our estimates we compared performance data of WIRTGEN GROUP equipment, computed from the results of our studies, in the various scenarios indicated above. CO₂e emissions values were based on data originating from various industry sources and may vary according to the source, year, and region:

Aggregate extraction emission value: Based on the emission value of final aggregates from Probas (German Environment Agency (UBA)) and internal calculations of the manufacturing process based on Kleemann crusher consumption values.
Bitumen emission value: Probas Database (German Environment Agency (UBA))
Lignite Dust emission value: CO₂ emission factors for fossil fuels Update 2022 (German Environment Agency (UBA))
Green Hydrogen emission value: JEC Well-To-Wheels Report v5 (European Commission’s science and knowledge service)
Cement Emission Factor: International Energy Agency (IEA) 2022
Truck Diesel consumption: ICCT Fuel efficiency Technology in European heavy-duty vehicles (state: +moderate engine technology)
Diesel (7% Biodiesel, common in Germany) emission value: DIN EN 16258 (WTW)
