Representatives of the United Nations Framework Convention on Climate Change signatory countries will on Monday gather in Mexico`s Cancun for a summit to draw out a plan to curb global warming. At the summit that will run until December 10, the leaders of the world`s twenty major economies will attempt to reach a binding agreement on curbing greenhouse gasses after 2012, when current emission reduction targets laid out in the Kyoto Protocol expire. The G20 leaders failed to reach an agreement at the last UN climate summit in December 2009, largely as a result of China`s reluctance to agree to binding commitments. China has consistently showed reluctance to commit to slashing greenhouse emissions, despite being the world`s largest emitter. In light of the disagreements, this year`s summit aims to reach less ambitious goals than last year`s. Deals on deforestation and technology transfers are expected to be met.
