Global Commercial Vehicle meeting continues calls for global regulatory harmonization on fuel efficiency and emissions reduction
European, North American and Japanese heavy-duty vehicle and engine manufacturers continue to call for global cooperation and regulatory harmonization to improve fuel efficiency and reduce emissions from the road freight sector, according to a summary of the recent 10th Global Commercial Vehicle meeting posted by the European Association of Automobile Manufacturers (ACEA).
More specifically, the assembled chief executives of manufacturers of heavy-duty commercial trucks and engines agreed on the need to expand the application of the UN ECE’s world-wide harmonized heavy-duty certification (WHDC) procedure for engine exhaust emissions; the importance of global diesel fuel specifications; the development of globally harmonized fuel-efficiency test procedures; and the promotion of harmonization of heavy-duty hybrid certification procedures.
This was the chief executives’ tenth meeting to discuss global issues and to recommend solutions to the regulatory challenges facing commercial vehicle manufacturers. Key issues discussed included fuel-efficiency improvements; reductions in greenhouse gas (GHG) emissions; global diesel fuel specifications; and issues related to heavy-duty engine and vehicle regulation and certification.
Globally, commercial vehicle manufacturers are taking decisive steps to overcome both short and long-term challenges. The industry is motivated by the commercial imperative to increase fuel efficiency, as well as the related aim of reducing greenhouse gas (GHG) emissions. Global cooperation to harmonize fuel efficiency related test methods will be given priority as this can deliver important cost savings to the industry, which will benefit our customers as well as wider society.
The meeting has also focused on longer-term issues with the objective to increase flexibility in connection with vehicle design, which can contribute to important emission reductions from the road freight sector. In examining these important technical areas, this high-level meeting has reaffirmed the importance of international cooperation in the commercial vehicles industry.—Harrie Schippers, President of DAF Trucks and Chairman of the ACEA Commercial Vehicle Board, Chair of the meeting
Evaluating developments since previous meetings, the chief executives discussed:
Steps towards adopting the worldwide heavy-duty emissions certification procedure (WHDC);
Developments in harmonizing diesel fuel specifications and regulations; and
Global cooperation on regulatory demands for improved fuel efficiency and reduced GHG emissions.
The executives of the assembled companies will work with their respective governments to speed up the adoption of WHDC procedure and to support the United Nations in the establishment of a globally harmonised procedure for heavy-duty hybrid certification. The participants reconfirmed that they would continue discussions with the UN on the development of global diesel fuel specifications. They also re-emphasized the need for concerted global action to reduce GHG emissions and promote the establishment of global test procedures for evaluating CO2 emissions from HDVs.
The international partners intend to assemble joint expert groups to address the following GHG-related topics:
- Engine Fuel Mapping
- Aerodynamic Drag
- Duty Cycles/ Driver Models
For the longer term, the leaders were encouraged to consider the potential of a harmonized approach to the following topics:
- Higher-capacity vehicles (HCV)
- Performance-based standards for HCV
- International intermodal loading units
They also affirmed that trans-national/trans-regional cooperative efforts by industry and governments to foster global harmonisation can lead to improvements for customers, the environment and for the industry.
Also attending this meeting were representatives of ACEA, the Truck and Engine Manufacturers Association (EMA), and the Japan Automobile Manufacturers Association (JAMA).
