Tokyo Metro Co., Ltd. and SMFL Mirai Partners Inc., a strategic subsidiary of Sumitomo Mitsui Finance and Leasing Co., Ltd. (SMFL), have announced the conclusion of a virtual Power Purchase Agreement (vPPA) utilizing solar power plants. Under this agreement, Tokyo Metro will receive the environmental value (approximately 60 million kWh annually) generated by existing solar power plants operated by an SMFL Mirai Partners' special purpose company, in the form of non-FIT, non-fossil fuel certificates. This is equivalent to an annual CO2 reduction of about 25,000 tons, representing approximately 7.5% of Tokyo Metro's total CO2 emissions. This initiative is a key part of Tokyo Metro's "Metro CO₂ Zero Challenge 2050" to achieve net-zero emissions.
