Tokyo, Japan – Heavy-duty vehicle and engine manufacturers from Europe, North America and Japan are asking for global cooperation to promote regulatory harmonization.

Such standards would improve energy efficiency and reduce the fuel consumption associated with on-road freight transport, the manufacturers said at a meeting in Tokyo. Among the key issues discussed were fuel efficiency improvements, reductions in greenhouse gas emissions, diesel fuel specifications, and issues related to heavy-duty engine and vehicle regulation and certification.

“In addition to their successful efforts to overcome the economic crisis, heavy-duty engine and vehicle manufacturers are also making clear progress in exhaust emission reductions and fuel efficiency improvements,” said Satoru Takeuchi, president of UD Trucks Corporation and chair of the meeting. “We confirmed that accelerating efforts aimed at harmonization of test procedures and standards are needed to advance the global objective of greenhouse gas reductions. The best approach to reach this objective is for governments and industry to work together.”

Among the issues discussed were adoption of the worldwide heavy-duty emissions certification procedure; harmonization of diesel fuel specifications and regulations; development of a certification procedure for heavy-duty hybrids; and fuel efficiency improvements and reductions in greenhouse gas emissions.
