摘要：In order to achieve global climate stabilization targets, it is an urgent task to develop low-carbon socie- ties in Asia, as Asian countries will account for almost half of both the global population and GHG emissions by 2050 in the business-as-usual scenario. It is necessary to identify leapfrog development pathways to realize a shift to low-carbon emissions and low resource consumption while simultaneously improving people’s daily lives through economic growth. This paper presents the GHG reductions in Asia required for achieving climate stabilization based on three different GHG emission allocation schemes to reduce global emissions by half by 2050 compared with the 1990 levels. Next, it describes the current climate change mitigation targets and actions proposed by individual countries in Asia, as well as the GHG emission reductions required in order to achieve these national targets. The gaps between the emission reduction requirements and the current targets proposed by each country are then identified. In order to bridge the gaps between the situation of the present national tar- gets and the global GHG reduction targets for 2050, it will be necessary to make significant changes to society itself. Finally, the paper outlines the approach taken by the authors’ team to design pathways towards low-carbon societies in Asia.
