By Koichi Yamada and Kanako Tanaka


When setting construction of euphoric and satisfying zero-carbon society as a goal, we should consider the back-casting scenario of how to reach it. To that end, it is necessary to use a simple but clear indicator of GDP and CO2 emissions without separating, economic development and decarbonization. To achieve the target below 2 degrees, technology development and diffusion (TD&D) play key role. This paper clarifies the usefulness and importance of quantitative technical evaluation that can be used for investment judgment and expansion of TD&D which practically accelerate to low carbonization and innovation in world.
