As part of the Bali Action Plan, adopted in 2007, all developed country Parties have agreed to “quantified emission limitation and reduction objectives, while ensuring the comparability of efforts among them, taking into account differences in their national circumstances.”
Developing country Parties agreed to “[nationally] appropriate mitigation actions [NAMAs] context of sustainable development, supported and enabled by technology, financing and capacity-building, in a measurable, reportable and verifiable manner.”
42 developed countries have submitted mitigation targets to the UNFCCC secretariat, as have 57 developing countries and the African Group (a group of countries within the UN).
