The UN climate summits, i.e. so called COP (Conference of the Parties) are global conferences, in the course of which action for climate policy is negotiated. The Climate Change Conference 2018 was held in Katowice, Poland. Previously, Poland hosted them twice – in 2008, in Poznań and in 2013, in Warsaw.
For the first time, the climate summit took place in Katowice. This year’s summit included: 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24), 14th Meeting of the Parties to the Kyoto Protocol (CMP 14) and the 1st Conference of Signatories to the Paris Agreement (CMA 1).
