Introduction UNIDO is preparing a GEF funded ‘full-size project’ entitled Upgrading of China Small Hydropower (SHP) Capacity. The proposed Project will focus on environmental upgrading of rural SHP stations in China, in line with the priorities of the Chinese Government, as outlined in its 12th FYP (five-year plan) 2011-2015. Since 2004, the central Chinese Government has listed rural hydro power development in its rural infrastructure construction tasks to further increase investments and loan input to support rural hydropower development. The UNIDO-GEF Project aims at supporting the SHP capacity expansion programme of the Ministry of Water Resources (MWR), by reducing the environmental impact of SHP plants to better meet the challenges imposed by climate change. The objective of this overall project is to reduce GHG emissions and dependence on fossil fuels through the promotion of upgrading, greening and improving the management of existing SHP stations, contributing to the competitiveness of China’s industries. Alongside important social and economic benefits, the project will improve local river ecology, hence contributing to adaptation of SHP plants to climate change. The project will transfer knowledge and technology in the field of green SHP within China, leading to positive environmental impacts. The overall Project is comprised of four components which are: • Component 1: Policy and institutional framework promoting green SHP plants. • Component 2: Greening and improving the management and safety standards of existing SHP plants. • Component 3: Knowledge base and capacities in the fields of green SHPs and improved and safe SHP management • Component 4: Monitoring and Evaluation This report is a summary
