In many countries, an important obstacle to achieving environmental goals has been the failure to adequately address the associated financial issues: the costs of achieving environmental goals, how those costs could be minimised, and the challenge of matching costs with available resources. This volume 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. In all these countries, they supported a process of dialogue and consensus building among the key stakeholders involved in financing environmentally-related infrastructure. The main ideas underlying this approach are the importance of realism, affordability and the cost-effective use of resources in achieving infrastructure development and environmental goals. By focussing on these issues, the application of FEASIBLE builds bridges between policy development and implementation.This report is part of the OECD's ongoing co-operation with non-member economies around the world.
