This book presents a method to develop financing strategies for investment-heavy environmental infrastructure, such as urban water supply, wastewater collection and treatment, and municipal solid waste. The strategies, supported by the FEASIBLE computer model, were developed in several countries of Eastern Europe, Caucasus and Central Asia (EECCA), in EU accession countries and China. This approach focuses on the importance of realism, affordability and the cost-effective use of resources in achieving infrastructure development and environmental goals.
