For some dimensions, countries could agree to transparency requirements if it is not possible to agree bounded flexibility. Some of this information depends on the commitment type, e.g. carbon neutrality commitments should be accompanied by a definition of carbon neutrality. However, much of the information would be needed regardless of commitment types, e.g. time frame, coverage of gases and sectors, GWP values or other GHG-equivalence metrics, treatment of LULUCF, estimated emissions reductions, any conditions attached, and any use of units from market mechanisms.
