On the morning of May 17, 2017, Dr Dai HanCheng of Peking University was invited to visit and give a report entitled "SSP3: AIM implementation of Shared Socioeconomic Pathways". A number of teachers and students attended the lecture. The lecture was hosted by associate professor Yu Biying.

　　Dr Dai has been working on multidisciplinary research on climate policy and energy economics. He used five years to develop and build a general equilibrium model (CGE) and database for China's national, provincial, 30 provincial and global policy analysis. The model has been one of the important decision-making support tools for the formulation of climate policies of national and provincial-level agencies. So ar, Dr. Dai has published 19 papers on important academic journals of environment and Energy economics, such as Energy economics. His research contents are extensive, whether INDC can be achieved, carbon tax, renewable Energy cost analysis, Energy consumption and health related research.　　

　　In this report, Dr Dehancheng first introduced the development of climate change scenarios from sres-rcp-ssp and the advantages and differences of SSP compared to SRES and RCP. He then presented the AIM/CGE model developed by the Japan National Institute of Environmental Research from the perspective of model and data. SSP3 reflects higher mitigation and adaptation challenges and future expectations of severe air pollution. For a detailed description of such a social and economic development path, this AIM/CGE model has been given a series of parameter adjustment and assumptions by reference literatures, showing a development path to quantified SSP3 scenario qualitative description.
