Hong-dian Jiang, a Ph.D. candidate from the Center for Energy & Environment Policy Research of the Beijing Institute of Technology, went to the International Institute for Applied Systems Analysis (IIASA) as a one-year joint Ph.D. scholar in Austria in September 2019. Dr. Purohit Pallav, his cooperation tutor, is a research scholar at the Air Quality and Greenhouse Gases (AIR) Program and is also a visiting faculty member to the Institute of Political Science at the University of Zurich, Switzerland. Dr. Pallav worked for the development of the GAINS Asia model with a particular focus on China and India. He focused on Non-CO2 Greenhouse Gas Emissions (F-gases), Energy Policy & Planning, Climate Change Mitigation, and Integrated Assessment Modeling.

　　Hong-dian Jiang’s main research interests are energy complex system modeling (i.e., CGE model), energy and environmental policy analysis, and carbon marginal abatement cost curves. During the second half of the academic visiting period, he mainly focused on the topic of “The cost-benefit comparisons of China’s and India’s NDCs based on carbon marginal abatement cost curves” with domestic and foreign tutors. As China and India are the two largest developing countries in the world, these two countries are the world’s largest and third-largest carbon emitters. Therefore, China and India play a pivotal role in the mitigation of global climate change. The co-benefits of carbon emission reduction provide an opportunity for the two countries to carry out deep emission reductions. To this end, based on the C3IAM/GEEPA model and a global multi-regional computable general equilibrium (CGE) model, in his study, he incorporated the co-benefits of carbon emission reduction into the carbon marginal emission reduction cost curve (MACCs), and then evaluated and compared the total abatement costs and cost-saving effects of achieving Nationally Determined Contributions (NDCs) target before and after considering the co-benefits for both of the countries. 

　　As the Coronavirus disease-2019 (COVID-19) broke out in Europe during the second half of the academic visit, the research team switched to the home-based work mode. While taking good care of himself, Hong-dian Jiang actively communicated with domestic and foreign tutors through video, email, WeChat, and other internet tools at any time, and discussed academic issues to effectively ensure the progress of scientific research.

　　During the doctoral period, not only Hong-dian Jiang published 3 papers as the first author in SSCI/SCI journals such as the Journal of Cleaner Production, Energy Economics, and Resources Policy, he also attended three academic conferences at home and abroad and made oral presentations.
