Several studies have reported pathways for the chemical industry to achieve net zero GHG emissions. Some are qualitative roadmaps developed by the Japanese government (Ministry of , whereas others are quantitative European or global studies . However, these studies failed to present a holistic perspective on the transition to net zero, omitting elements such as financial impacts, end-of-life emissions, demand-side measures, and environmental impacts other than GHG emissions. Our group has recently reported quantitative pathways for the global chemical industry to achieve scope 1, 2, and 3 net zero, while taking these previously omitted perspectives into consideration . By applying this methodology to Japan, this study presents, for the first time to the best of our knowledge, quantitative pathways to scope 1, 2, and 3 net zero from today until 2050 for the chemical industry operating in Japan. In addition, it provides strategic insights into the necessary actions based on the quantitative analysis. The scope 3 emissions in this study are limited to categories 1 and 12 only (see the Method section below for more detail).
