This document contains information on measures contributing to addressing climate change with a focus on ways to abate greenhouse gas (GHG) emissions and enhance removals by sinks. The sectors covered are energy (supply and demand), agriculture, land-use change and forestry, and waste management. This document also highlights the needs and constraints of Parties not included in Annex I to the Convention relating to the assessment and implementation of activities meant to abate and sequester GHGs. There are many such initiatives and activities. The majority of those reported by Parties were in the energy, agriculture, land-use change and forestry, and waste management sectors. Many of the measures that are being considered or have already been implemented deliver multiple benefits for development, the environment and the global climate system.
