We emphasize our strong support for a successful outcome to the Third Conference of the Parties in furthering the objectives of the UN Framework Convention on Climate Change (UN-FCCC). We note that all APEC members can make important contributions to this effort. We also agree that the enhancement of energy efficiency plays an important role in addressing climate change. We affirm the importance of flexible and cost-effective cooperative approaches to reducing greenhouse gas emissions, including by promoting the development and diffusion of beneficial technologies. We recognize the legitimate needs of developing economies to promote their sustainable development in furthering the objectives of the UN-FCCC and, in this respect, the importance of enhancing the availability of beneficial technologies
