ENVIRONMENT PROTECTION COUNCIL URBAN ENVIRONMENT MANAGEMENT COMMITTEE Foreword Many Asian cities are on the threshold of a major environmental crisis in the form of air pollution. The deteriorating air quality in cities is a result of rapid economic expansion, rise in population, increased industrial output and unprecedented growth in numbers of passenger vehicles. The impacts of air pollution are well known: adverse health effects, rising health costs, damage to ecological and cultural properties, deterioration of built environment. In Kathmandu Valley cities, the main contributor of air pollution comes from the transport sector, followed by power plants, industrial units and burning of garbage. Fuel quality and engine conditions significantly influence the' level of air pollution. To arrest this growing problem, a concerted effort with public involvement is essential. Awareness of the issue, proactive policies, economically affordable standards and technologies and effective enforcement are key elements in an air quality management strategy. A long- run perspective shows that early adoption of policies for environmentally safer technologies can allow developing countries to resolve some of the most difficult problems of industrialization and growth at lower human and economic cost. Kathmandu Valley cities joined the World Bank-executed Metropolitan Environmental Improvement Program (MEIP) in 1993. At the inter-country workshop held in Hawaii in 1990, the cities facing serious air pollution problems sought MEIP intervention to assist in finding solutions. In response to this, l.TRBAIR was conceived and launched in Kathmandu Valley, Nepal in 1993. URBAIR has assisted His Majesty's Government/Nepal, Environment Protection Council, Urban Environment Management Committee to develop a strategy and time- bound action plan for air quality management in Kathmandu Valley. For the first time, it brought together the different stakeholders - sectoral agencies, private sector, NGOs, academics, research bodies and media -- to formulate a strategy. From this group was formed the Technical Committee that deliberated for several months with technical support provided by a team of national and international experts. The outcome is the action plan included in this document. The result is truly impressive and His Majesty's Govemment/Nepal, Environment Protection Council, Urban Environment Management Committee is fuBy committed to the implementation of the plan. We will need the support of the international community in realizing the goals ofthe plan. I wish to acknowledge with gratitude all those who contributed to the development ofthe strategy and plan, especially to MEIP for facilitating the process.

URBAIR core funds were provided by United Nations Development Programme, the Australian International Development Agency, the Royal Norwegian Ministry of Foreign Mfairs, the Norwegian Consultant Trust Funds, and the Netherlands Consultant Trust Funds. Host governments and city administrations provided substantial input City studies were conducted by the Norwegian Institute for Air Research (NILU) and the Institute of Environmental Studies (IES) at the Free University in Amsterdam, with assistance from the selected local consultants: Mr. Anil S. Giri and Mr. Rishi Shah, Royal Nepal Academy of Science and Technology; Dr. Madan L. Shrestha, Department of Hydrology and Meteorology, and Dr. Bimala Shrestha, Tribhuvan University. The city-level technical working groups provided operational support, while the steering committee members gave policy direction to the study team. The National Program Coordinator ofl\.1EIP-Kathmandu, Mr. Guru Bar Singh Thapa, contributed greatly to the successful outcomes. At the World Bank, URBAIR was managed by litendra Shah and Katsunori Suzuki, and under the advice and guidance ofMaritta Koch-Weser and David Williams. Colleagues from the World Bank Country Departments and Resident Mission helped with the program. Tanvi Nagpal was responsible for technical accuracy and editing. Management support was provided by Erika Yanick, Sonia Kapoor and Ronald Waas. Nicole Schofer and Sheldon Lippman provided editorial support. Many international institutions (World Health Organization, United States Environmental Protection Agency, United States Asia Environment Partnership) provided valuable contribution through their participation at the workshops.
