Asian Low-Carbon Society Scenario Development and Policy Implementation
The development of mid-and long-term scenarios for the Asian region which show the ways to achieve a low carbon society (LCS) together with economic development, and with evaluation measures to realize these scenarios, is an issue of pressing concern. If we set the 2 degree target as the climate stabilization target, it is suggested that we need to cut greenhouse gas (GHG) emissions by half by 2050. We need to identify possible leapfrog pathways rather than conventional ones, using scientific findings. AIM (Asian Pacific Integrated Model) was developed in 1990 for assessing policy options for stabilizing the global climate, particularly in the Asian-Pacific region, with the objectives of reducing GHG emissions and mitigating the impacts of climate change (AIM, 2011). AIM is a large-scale computer simulation model developed by the National Institute for Environmental Studies in collaboration with Kyoto University and several research institutes in the Asian-Pacific region. We have also research collaboration with Asian researchers from countries such as China, India, Korea, Thailand, Malaysia, Indonesia, Vietnam, Cambodia, and Bangladesh (NIES, 2011). In this chapter, I would like to investigate the relationship between scientific findings – especially those based on simulation models – and policy implementation at the national level ( Japan) and local level (Shiga prefecture and Kyoto City in Japan, and Iskandar in Malaysia).
