Post-Paris COP21 - by IIGCC

Work to secure the Paris agreement started years ahead of COP21.
In particular, through the process by which countries chose by how much to cut their own emissions – intended nationally determined contributions (INDCs) – national climate plans were developed way ahead of the Paris conference, and nearly 180 nations had submitted one by the time COP21 began.
As a consequence, significant political capital had been invested into the Paris process well before the start of the conference.
