Since 2009, the Nordic countries have increased their efforts to support developing economies in the mobilization of private finance. It is now time to take stock of the success stories. Regardless of the progress, several barriers limit the Nordic ability to scale up private climate finance even more. This brief presents ideas for addressing some of these the barriers and increasing the ambition in mobilizing private finance, including considerations on de-risking solutions and the applicability of Article 6 under the Paris Agreement. The brief was produced as part of the Nordic Public-Private Platform on Mobilization of Climate Finance Mobilization, and ahead of the global climate conference in Katowice, December 2018. It builds on previous studies funded by the Nordic Council of Ministers, such as “Mobilizing climate finance flows – Nordic approaches and opportunities”.
