China: Phase III LDV fuel-consumption standard and HDV test procedure

Staff reports

China’s Phase III LDV standards will constitute its first corporate average fuel consumption standards, and an effective implementation plan is critical to success. At the same time as it finalizes the Phase III standards, the Chinese government is also developing a test procedure for estimating fuel consumption of medium- and heavy-duty vehicles, which will be the basis of a new fuel-consumption standard in that rapidly growing transportation sector.

In late June, ICCT’s Hui He met with CATARC’s JIN Yuefu for discussions on the implementation plan for Phase III, to identify areas where the ICCT could provide support. The meeting focused on three major issues: point of regulation, transmission and verification of data, and the structure of non-compliance penalties. CATARC is working with officials from the Ministry of Industry and Information Technology (MIIT) and the Ministry of Finance (MOF), the key central agencies involved in implementing Phase III to develop a formal initial proposal.

Also in June, the MIIT released a proposed M&HDV fuel-consumption test procedure for public comment. The proposal is the result of several years of research work by CATARC staff and the technical committee. It recommends evaluating fuel consumption of a base model through whole-vehicle testing and estimating fuel use of variant models through simulation modeling. ***CHECK REWORDING*** In early July, ICCT staffers Fanta Kamakate and Freda Fung, along with Michael Walsh, chair of ICCT’s Board of Directors, met with CATARC’s team in Beijing to offer ICCT’s initial comments. Discussions focused on measures to minimize the possibility of gaming and ensure that results reflect real-world fuel consumption as closely as possible. Incorporating the discussions during the meeting, the ICCT submitted final written comments on the proposed test procedure to CATARC on July 15.

Attribute-based efficiency standards

This paper summarizes differences between size-based and mass-based standards and discusses their relative advantages and disadvantages. The authors argue for a reconsideration of the mass-based regulatory framework where it is in use and against its extension into as-yet-unregulated light-duty vehicle

CNG Bus Emissions Roadmap

The availability and low cost of natural gas, less stringent new engine emissions standards, and fuel sulfur levels that inhibit the use of the most advanced diesel engines all contribute to a continued high level of interest in CNG vehicles

Feebate best practices

Summarizes one of the most promising fiscal policy tools available to complement vehicle emissions standards: so-called feebate programs, in which more efficient vehicles receive rebates and less efficient vehicles are assessed fees.

Lightweight future

A new study by Lotus Engineering finds that, using existing or soon-to-be-available mainstream engineering techniques, automakers can reduce passenger-vehicle mass by one third in exchange for a 3% increase in component costs.
