Wissmann: CO2 emissions from heavy trucks will continue to fall

Berlin, 12 May 2017

From 2019 VECTO will be used to determine and report commercial vehicle CO2 values

The EU Member States have cleared the way for the determination of CO2 emissions from heavy-duty commercial vehicles. As a result, from 2019 onward CO2 values that can be compared will be determined and reported for newly produced and approved heavy-duty commercial vehicles in Europe for the first time. Matthias Wissmann, President of the German Association of the Automotive Industry (VDA), said: “The commercial vehicle industry welcomes the decision, which creates the basis for even greater transparency and competition on the commercial vehicle market. This will benefit customers in the transport and logistics sector as fuel consumption and CO2 emissions continue to fall. The approach that has now been approved will give the EU a leading role in practical determination of CO2 emissions from heavy trucks.” The draft Regulation was approved by the Technical Committee on Motor Vehicles (TCMV).

From the beginning of 2019, heavy-duty commercial vehicles – initially those in long-distance transport and regional distribution – will be given an individual and practically relevant CO2 value. More vehicle categories will gradually be added, e.g. vehicles used in urban distribution. Preparations have also already begun for including buses.

Certified and comparable values for the fuel consumption and CO2 emissions from heavy commercial vehicles have not been available before now. The immense diversity of heavy-duty commercial vehicles, and their broad range of uses, necessitated the development of a completely new, high-performance simulation-supported procedure. VECTO (Vehicle Energy Consumption Calculation Tool), which was developed by the European Commission and the Graz University of Technology, is one such instrument. Now for the first time it will be possible to determine the CO2 emissions from entire vehicles, i.e. from tractors with a semitrailer or trailer and tires, including all the relevant vehicle components. Using measured and certified input data and realistic driving cycles, the system can determine fuel consumption and CO2 emissions individually for all vehicle configurations and for specific use profiles. Studies by the European Commission prove that VECTO delivers highly accurate results close to those in real-world conditions.

Wissmann emphasized, “The crucial advantage of VECTO is that it is the first system to reflect the whole vehicle and thus the enormous complexity of the commercial vehicle market. Virtually no two commercial vehicles are alike. With VECTO, all the individual contributions that truck manufacturers, tire manufacturers, suppliers and trailer manufacturers make to reducing consumption are taken into consideration. This will enable the customers to adapt their new vehicles to make them even more fuel efficient, which will again greatly boost the competition for the most economical vehicles.”

Even without being required by law, the commercial vehicle industry has continually made considerable improvements in the efficiency and consumption of its new vehicles. “In the last twenty years alone, fuel consumption has been continually brought down by an average of more than 1 percent every year. At the same time, we have also reduced pollutant emissions in real driving conditions by around 95 percent,” Wissmann added.

The VDA president closed by emphasizing, “The commercial vehicle industry has backed and supported the development of VECTO. The dates set for introducing the new regulation do, however, represent a challenge. Vehicles produced from January 1, 2019, onward must fully certified using VECTO. But vehicles that were already built although not registered until after mid-2019 are also included in the new regulation. That is challenging in view of the extensive upstream and downstream services in the entire supply chain. Furthermore, development of VECTO must continue rapidly. This is because important fuel-saving technologies such as GPS cruise control and hybrid drives can make a major contribution to reducing consumption but are not included in VECTO at present. We are therefore working on their swift integration into VECTO.”
