Clean Fuels and Vehicles Program

Vehicles number in Asia will exceed one billion in 2035. Fuel consumption and resulting CO2 emissions will grow by 400% compared to 2005. Achievements to curb particulate emission reduction will be offset by vehicle growth. World Health Organization confirmed that diesel emissions cause cancer. Asia needs tighter vehicle emission and fuel quality standards that go beyond light-duty vehicles, and supplemented with fuel economy standards, policies and programs for in-use vehicles and vehicle fleets. These efforts should especially focus on reducing diesel emissions.

Projects and Activities:

Our Clean Fuels and Vehicles Program consist of three components:

  1. Facilitate adoption of tighter standards for cleaner fuels and vehicles by Asian countries. Clean Air Asia works with national governments, industry and other stakeholders to agree on the introduction of tighter vehicle emission standards and fuels with 50 ppm Sulfur or less with a clear timeline. Similar policy dialogues will be held on fuel economy standards and on alternative fuels and vehicles. We bring together governments, partners and experts from different countries to share experiences with the aim to fast track and harmonize standards across Asia.
  2. Strengthen policy frameworks for effective management of in-use vehicles. Starting with a database on in-use vehicles in Asia, we will work with governments to improve vehicle inspection and maintenance systems, restrict the import and sales of polluting second-hand vehicles and engines, and phase out polluting vehicles. Specifically, policies and financing mechanisms will be established to phase-out of 2-stroke 3-wheelers by replacement with 4-stroke or electric 3-wheelers or conversion to LPG.
  3. Introduce clean fleet management programs for public and private fleet operators. Building on the Clean Fleet Management Toolkit of UNEP and TNT, Clean Air Asia developed tailored toolkits for bus fleets and truck fleets. Depending on what is most suitable for each country, a Clean Fleet Management program will be established nationally for bus, truck, corporate, government and/or other fleets. We will support the design and establishment of such programs and build partner networks to roll these out.

Goals 2016 for Asia

  • Asian countries have Euro 4 or equivalent emission standards for light and heavy duty vehicles or have approved their introduction within four years.
  • Asian countries have fuel economy standards for light and heavy duty vehicles or have approved their introduction within four years.
  • Asian countries have effective programs for in-use vehicles including inspection and maintenance, phase out of polluting vehicles and Clean Fleet Management
