Work on the Paris climate framework, to be agreed in December 2015, occurs at an interesting juncture: nearly 40 Parties have either implemented or are developing carbon-pricing policies at national or sub-national levels. Given this progress, the agreement should provide support for those Parties (and others) to build and expand these systems. A fundamental assurance could support Parties in efforts to cooperate in achieving ambitious, cost-effective mitigation contributions through use of market-based pricing systems. IETA, its member companies and coalition partners will be writing about the importance of carbon pricing in the 2015 agreement throughout the year.
