The distribution and marketing sectors urgently need to implement green logistics in trucking to achieve carbon neutrality. This is because the transportation sector accounts for about 20% of Japan’s total CO2 emissions, with trucks contributing around 40% of these emissions. The rise of e-commerce platforms such as Amazon and Rakuten has significantly increased truck usage, which has the potential to elevate CO2 emissions in Japanese logistics. Regarding CO2 emissions, the logistics industry in Japan is currently facing a trade-off between extreme weather conditions and global warming and the increase in truck transportation. An effective way to address this problem is through green logistics. The author proposes a four-phase action plan based on the current level of penetration and difficulty of execution: Phase 1 (energy use reform), Phase 2 (logistics digital transformation, also known as logistics DX), Phase 3 (logistics structural reform), and Phase 4 (robotization). Each phase of the action plan involves crucial social innovations and, if implemented as envisioned, will enable a considerable reduction in CO2 emissions and contribute toward a carbon-neutral society.
