COP 25 took place in the Spanish city of Madrid, thousands of miles from Chile where it was originally scheduled to take place. This change of location did not change the central business of this very important meeting, which was meant to complete the unfinished business of the COP24. Notably, COP25 was expected to finish the work on the rules to operationalize the Paris agreement, and allow Parties and stakeholders to enhance their emission reduction ambition for 2020.
