Action Plan Overview for Chongqing, PRC
Action plan on strengthening vehicle inspection and maintenance in Chongqing, People's Republic of China
This document outlines elements of an Action Plan to reduce vehicle emissions using IM and other means.

Scope and objectives

This Action Plan will focus on strengthening vehicle inspection and maintenance (IM) in Chongqing. Located in southwest China, Chongqing is the fourth municipality directly under the supervision of the Central Government.


Chongqing is one of four municipalities directly administered by the Central Government of the People’s Republic of China.

For many years, Chongqing’s main air pollution problem was caused by sulfur dioxide (SO2), primarily from coal burning. However, air quality monitoring data revealed that average nitrogen oxide (NOx) concentrations have doubled in the past five years, an indication that vehicle emissions have increased rapidly during this period.

To improve Chongqing’s inspection and maintenance capability, a multi-sectoral action plan group (MAPG) was established at the start of this Regional Technical Assistance project. Members consisted of local and national government agencies, academic institutions, and representatives from inspection stations, the auto service industry, and public transport companies. The MAPG met regularly to discuss the proposed action plan; members who came from outside Chongqing were also able to share their experiences and gain from the process.

The Multi-sector Action Plan Group (MAPG) will assist in the formulation and implementation of this action plan. MAPG was set-up at the beginning of this project.

MAPG members:

  • Government agencies on both national and local levels

    1. National: State Environmental Protection Administration (SEPA)
      Local:Chongqing Environmental Protection Bureau (CEPB)
      • Responsible for setting up IM regulations and emission standards
      • Exercises unified supervision and administration
    2. National: Ministry of Public Security of China
