Abstract: Based on the IPCC WGIII AR5, this paper analyzed the conclusions of CO2 and greenhouse gas (GHG) reduction pathway and counter-measures contributions in the fields of energy supply, industry, transportation, building, agriculture, forest and other land use (AFOLU). Except the AFOLU, the GHG emissions of all the sectors above have been increasing since 2000, and the energy supply, industry, transportation, and building contribute 47%, 30%, 11%, and 3% respectively. In the future, these four sectors will be the main emission sources and GHG reduction fields. By developing and updating technologies, improving energy and raw materials efficiency, refining energy structure, strengthening the management of waste, optimizing products and service demand, and applying the carbon capture and storage (CCS) and the carbon dioxide removal (CDR), the GHG emissions from these four sectors will reduce by 15%-80% compared with the BaU scenario. All of these emission reduction measures have reference significance for China’s CO2 emission reduction.

Key words: IPCC AR5, scenario, sectors, GHG reduction counter-measures
