JOINT UNDP/WORLD BANK ENERGY SECTOR MANAGEMENT ASSISTANCE PROGRAMME (ESMAP) PURPOSE The Joint UNDP/World Bank Energy Sector Management Assistance Programme (ESMAP) is a special global technical assistance program run by the World Bank's Industry and Energy Department. ESMAP provides advice to governments on sustainable energy development. Established with the support of UNDP and 15 bilateral official donors in 1983, it focuses on policy and institutional reforms designed to promote increased private investment in energy and supply and end-use energy efficiency; natural gas development; and renewable, rural, and household energy. GOVERNANCE AND OPERATIONS ESMAP is governed by a Consultative Group (ESMAP CG), composed of representatives of the UNDP and World Bank, the governments and other institutions providing financial support, and the recipients of ESMAPs assistance. The ESMAP CG is chaired by the World Bank's Vice President, Finance and Private Sector Development, and advised by a Technical Advisory Group (TAG) of independent energy experts that reviews the Programme's strategic agenda, its work program, and other issues. ESMAP is staffed by a cadre of engineers, energy planners, and economists from the Industry and Energy Department of the World Bank. The Director of this Department is also the Manager of ESMAP, responsible for administering the Programme. FUNDING ESMAP is a cooperative effort supported by the World Bank, UNDP and other United Nations agencies, the European Community, Organization of American States (OAS), Latin American Energy Organization (OLADE), and public and private donors from countries including Australia, Belgium, Canada, Denmark, Germany, Finland, France, Iceland, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Sweden, Switzerland, the United Kingdom, and the United States. FURTHER INFORMATION An up-to-date listing of completed ESMAP projects is appended to this report.

Preface This report is the principal output of a technical assistance project in Vietnam executed by the World Bank's Energy Sector Management Assistance Program (ESMAP) and financed by the Swedish International Development Authority (SIDA). The activity pursued recommendations of a previous ESMAP household energy strategy study which are to determine: (i) how the exisiting coal briquette industry can be improved, and (ii) how the current government program for the dissemination of higher efficiency cookstoves can be commercialized. After examining these subjects in detail, the report recommends a five-year pilot program to effectively push tlle market in this direction. The technical assistance activity benefited immensely from the support of the Energy Institute of Vietnam, particularly Dr. Tan Quoc Cuong, Director, Dr. Pham Kanh Toan, Head of International Cooperation and Mr. Nguyen Duy Thong, household energy specialist. Support was also provided by other agencies including the Ministry of Mines, Hanoi Architectural Institute, Vietnam Coal Trading Company, Domestic Coal Company and others. The World Bank/ESMAP team consisted of Ernesto Terrado (task manager), Wolfgang Mostert (economist), Roland Siemons (coal briquette specialist), Keith Openshaw (household energy specialist) and Xiao Ming Song (stoves technologist). The final report was written by Ernesto Terrado from contributions of the team members. TABLE OF CONTENTS PREFACE I.
