The 21st Conference of Parties (COP) was held at Le Bourget, Paris between the 30th November and 12th December 2015. It was convened with the aim of producing a new, legally-binding agreement that commits every country, from all stages of development, to reducing emissions in order to mitigate against the impending climatic catastrophe. At the 2009 COP 15 in Copenhagen, generally regarded as a failure, governments also convened with the aim to create a similarly legally-binding deal. However, it culminated with the USA and BASIC countries drafting a non-legally binding agreement, the Copenhagen Accord. This agreement incorporated countries responsible for 80% of the world’s pollution  and its failure to be legally-binding and applicable to all countries greatly increased the importance of the climate talks in Paris (COP 21). The four previous COPs and in particular the ‘Lima Call for climate action”, devised at COP 20 (Lima 2014) , laid the foundations for the Paris talks. There was a renewed sense of optimism that the talks would prove successful. At 18:26 on 12th December 2015 (the day after the Conference’s original finish date) this optimism was rewarded when Laurent Fabius, the French Foreign Minister brought his gavel down on COP 21, announcing that the Paris Agreement, a new climate deal, had been adopted.
