The Asia-Pacific Partnership on Clean Development and Climate, also known as APP, was an international, voluntary, public-private partnership among Australia, Canada, India, Japan, the People's Republic of China, South Korea, and the United States announced July 28, 2005 at an Association of South East Asian Nations (ASEAN) Regional Forum meeting and launched on January 12, 2006 at the Partnership's inaugural Ministerial meeting in Sydney. As of 5 April 2011, the Partnership formally concluded although a number of individual projects continue. The conclusion of the APP and cancellation of many of its projects attracted almost no media comment. Foreign, Environment and Energy Ministers from partner countries agreed to co-operate on the development and transfer of technology which enables reduction of greenhouse gas emissions that is consistent with and complementary to the UN Framework Convention on Climate Change and other relevant international instruments, and is intended to complement but not replace the Kyoto Protocol., Ministers agreed to a Charter, Communique and Work Plan that "outline a ground-breaking new model of private-public task forces to address climate change, energy security and air pollution." Member countries account for over 50% of the world's greenhouse gas emissions, energy consumption, GDP and population. Unlike the Kyoto Protocol (currently unratified by the United States), which imposes mandatory limits on greenhouse gas emissions, the Partnership engages member countries to accelerate the development and deployment of clean energy technologies, with no mandatory enforcement mechanism. This has led to criticism that the Partnership is worthless, by other governments, climate scientists and environmental groups. Proponents, on the other hand, argue that unrestricted economic growth and emission reductions can only be brought about through active engagement by all major polluters, which includes India and China, within the Kyoto Protocol framework neither India nor China are yet required to reduce emissions. Canada became the 7th member of the APP at the Second Ministerial Meeting in New Delhi on October 15, 2007. Canada's Prime Minister Stephen Harper earlier expressed his intention to join the Partnership in August 2007, despite some domestic opposition. Aims U.S. former President George W. Bush called it a "new results-oriented partnership" that he said "will allow our nations to develop and accelerate deployment of cleaner, more efficient energy technologies to meet national pollution reduction, energy security and climate change concerns in ways that reduce poverty and promote economic development." John Howard, the former Australian Prime Minister, described the pact as
