Especially in the run-up to COP 21 in Paris and in conjunction with COP 22 in Marrakesh, the last decade has seen a strong increase in non-state actors' actions to move towards climate change mitigation and adaptation. Alongside other nonstate actors, they are increasingly recognized for their potential in raising global ambitions in the face of climate change. Most initiatives were launched in 2014 and 2015, since when the number of new initiatives has continuously increased, with eleven being launched in 2017. In addition, two high-level champions were appointed to encourage the engagement of interested Parties and non-Party stakeholders and to further the initiatives launched as part of the Lima-Paris Action Agenda, among others.
