The path towards a post-2012 climate regime had to be launched at COP 13/CMP 3 taking place in December 2007, in Bali, Indonesia, if an agreement was to be reached in 2009. This timeline was necessary to allow for the new agreement to enter into force prior to 2012. As part of his strategy, the Secretary-General quickly integrated climate change into his regular meetings with world leaders. Of particular consequence, on 16 January 2007, only two weeks after the start of his term, he held his first meeting with United States President George W. Bush.
