COP24 was held in Katowice, Poland, between 2 and 15 December 2018. The main objective was to set out a so-called “rulebook” to implement the 2015 Paris Agreement, which will enter into force in 2020.
This involved rules across the full spectrum of the agreement, such as on the structure and content of nationally determined contributions, on how to measure greenhouse gas emissions and actions to reduce these, as well as on reporting on climate finance contributions. Despite the daunting task, the COP24 was largely successful in that agreement was reached on all issues, except the so-called Article 6 voluntary market mechanisms.
This relates to internationally transferred mitigation outcomes between countries (Article 6.2) and private entities (Article 6.4) and further talks on this have been deferred to the next year’s COP25 in Chile.
