World Bank/Ecofys/Vivid Economics:State and Trends of Carbon Pricing

2015 witnessed an historic global step forward in taking action on climate change. In Paris, world leaders reached an agreement at the 21st Conference of the Parties (COP 21) to the United Nations Framework Convention on Climate Change (UNFCCC) to keep the global average temperature increase to well below 2°C and pursue efforts to hold the increase to 1.5°C. The Paris Agreement encouraged all countries, for the first time, to make individual, voluntary commitments to contribute to this global goal, marking the beginning of a new era in the cooperative effort to limit climate change.
