There are various ways in which this could be achieved, e.g. the commitments could be included in the core agreement, in an annex to the agreement, in separate INF documents, or in a separate COP decision. Listing the commitments in an annex to the 2015 agreement or a set of COP decisions, rather than as part of the core agreement itself, could make them easier to subsequently modify. The commitments included in the 2015 agreement could only be the first round of a longer-term process of setting mitigation commitments, with a view to achieving the long-term 2 °C global goal.
