As the TOSSD framework is to be agreed by mid-2017, inputs from the international community can contribute to ensuring that TOSSD is defined in a way that, if desired, is helpful to tracking progress on climate finance commitments. The main changes relating to reporting of climate finance are that: this reporting is to cover support “mobilised” as well as provided, it is now mandatory for all “developed” countries (not just Annex II countries) to report on support, and that “other” countries providing support are also encouraged to report on this information. The Paris Agreement also indicates that developed countries are to biennially communicate indicative information, as available, on climate finance “to be provided” (Box 2). The estimation of projected financial support for a specific area can be challenging, particularly for countries with annual budget cycles.
