The transparency of INDCs—that is, the completeness and clarity with which the intended meaning of INDC content is presented—is critical to assessing both national and global ambition on reducing GHG emissions. In addition, transparency in the INDCs can promote trust and accountability among Parties, both of which are essential for successful implementation of inter- national agreements.

This paper evaluates the transparency of the GHG emissions targets presented in the INDCs of eight top-emitting Parties—Brazil, China, the European Union, India, Indonesia, Japan, Mexico, and the United States— which, together, contribute nearly two thirds of annual global GHG emissions. Using the Open Book framework developed by World Resources Institute, we present information in each Party’s INDC related to its emissions target(s) and identify any transparency gaps— that is, information that is unclear or not made explicit.
