In December 2015, the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, replacing the 1997 Kyoto Protocol and putting international climate policy on a new footing from 2021 onward.
As a party to the agreement, Switzerland has committed to cutting its emissions by half by 2030 compared to their 1990 levels, achieving at least 60% of reductions within its borders. As for the remaining part of required reductions, it plans to make use of the cooperative approaches defined in article 6 of the Paris Agreement, which allow Switzerland to count reductions achieved in another country toward its own emission target.
Relevant rules and modalities have largely been agreed by contracting states in December 2018 in Katowice (Poland). Negotiations will continue in 2019 and should be finalised at the next conference at the end of 2019 in Chile. Full operationalisation will most likely require further rounds of negotiation.
