Reflecting the growing momentum for carbon pricing worldwide, the 2017 edition of the State and Trends of Carbon Pricing targets the wide audience of public and private stakeholders engaged in carbon pricing design and implementation. This report also provides critical input for negotiators involved in the implementation of the Paris Agreement, particularly for the meeting of the Conference of the Parties (COP} 23 to be held in Bonn in November 2017. As in the previous editions, the report provides an up-to-date overview of existing and emerging carbon pricing initiatives around the world, including national and subnational initiatives. Furthermore, it gives an overview of current corporate carbon pricing initiatives. Another key focus of the report is on the importance of an integrated approach to climate finance and climate markets, together with domestic policies. The analysis shows how such an integrated approach can be used to mobilize the scale of low-carbon investments needed to achieve the below 2°C temperature target and outlines a transition scenario and the possible role of results-based climate financing to catalyze climate markets.
