Background
The Technology Cooperation Agreement Pilot Project (TCAPP) was initiated by the U.S. Government in August of 1997. It recognized the need to establish a mechanism to promote cooperation in the transfer of technology in accordance with Articles 4.1(c) and 4.5 of the UN Framework Convention on Climate Change (UNFCCC). More information about UNFCCC Articles 4.1(c) and 4.5. 
TCAPP's primary goal was to create a means to implement Article 4.5 by assisting developing country teams to define and implement technology cooperation priorities. This was done through a two-phase process. In the first phase, technology cooperation frameworks were developed to define a country's technology priorities and map out actions to attract investment in such technologies. Such actions included ways to address market barriers and promote direct private investment. In the second phase, TCAPP assisted in implementing the action plans in order to attract in-country, donor, and private investment support to meet the host country's priority technology needs and reduce greenhouse gas emissions.
In addition to EPA, TCAPP was supported by the U.S. Agency for International Development (USAID) and the U.S. Department of Energy (DOE). The National Renewable Energy Laboratory (NREL) was a participant in the implementation of TCAPP for the U.S. Government.
In 2002, TCAPP became the Climate Technology Partnership (CTP). This move reflected a shift from the pilot-project nature of TCAPP to a stronger market-transformation focus. CTP promotes investment in market-viable, clean energy technologies that help meet development goals of participating countries. CTP works with interagency teams in China, South Korea, and Mexico to select technology priorities and develop strategic plans to increase investment in these technology areas. EPA, USAID, and DOE continue to sponsor CTP activities except in China where they are sponsored only by EPA and DOE.
China Wind Technology Partnership
CTP launched its activities in China under the Wind Technology Partnership (WTP) due to their exclusive focus on increasing the use of grid-connected wind power. WTP activities in China include support for regulatory issues (including advice on China’s recently passed National Renewable Energy Law) and provincial capacity building (including the development and rollout of a wind resource geospatial toolkit for Hebei province).
