Since the adoption of the Rio marker system, the information on support to the environment, including climate, desertification and biodiversity has incrementally improved. A revised definition of the climate markers and a guidance table to improve scoring, have been included in the revised Converged Statistical Reporting Directives of the OECD (OECD, 2016c). Overall, the new transparency framework for climate finance and the commitment to greater transparency of financing for sustainable development (UN, 2015a, UN, 2015b) will play an important role in enabling countries to hold each other to account, and in enabling citizens and communities around the world to hold their governments to account.
