A Research of the trades of multi-country-section carbon emissions and energy uses under the drive of the process-technology progress

the process-technology progress which is caused by the improvement of the productive technologies can reduce the demands of the intermediate inputs in the productive process, and then reduce the energy demands and the carbon emissions. Thus, to improve the level of process technologies is an important way for the global carbon emission abatement. In this paper, based on Jin (2012)’s model, a general equilibrium model of multi-country-section economy was built. Coupled with the climate system of RICE model, a climate-economy integrated assessment model was built with the interactions between the economic system and the climate system.Coupled with the climate system of RICE model, a climate-economy integrated assessment model was built with the interactions between the economic system and the climate system.Based on this model, the carbon emissions and the energy demands of different countries and sections were studied. The simulated outcomes show that the process-technology progress can bring on early peaks of energy demands and carbon emissions. Under the three different scenarios, China will reach its carbon emission peak at year 2034, 2030, and 2022 respectively. In the more bold scenario 3, the accumulated carbon emission of China can reduce to 93GtC, accomplishing the abatement target of 100GtC. Besides, along with the progress of the process technologies, the developing countries like China and India have larger abatement potentials, which in the sections, the energy section and the service sections have larger abatement potentials.
