概要	This study examines Japan’s carbon-neutral policy in the automotive sector. To tackle carbon neutrality, the Japanese government and industry have introduced two manufacturing-related strategies. The first is Multi-Pathway Strategy, which promotes not only battery electric vehicles but also a variety of powertrain vehicles by using a technology-neutral approach (namely, innovation policy). The second is the establishment of green supply chain networks. These strategies align with the life-cycle assessment (LCA) concept that calculates the total CO2 emissions of the whole automotive supply chain network but are based on the not commonly used Tank-to-Wheel method that calculates CO2 emissions during the driving process only. This study asserts that a technology-neutral approach based on LCA can be a more practical policy for greenhouse gas reduction under the uncertainty of the automotive technology and energy policy.
