As reported in Associated Press (AP) on April 27, 2022, Tokyu Railways’ network of seven train lines and one tram service was switched to renewable energy sources starting April 1, 2022.[1] Green energy is being used at all of its stations, including for vending machines, camera screens, and lighting. Tokyu employs 3,855 people and connects Tokyo with Yokohama. The company operates more than 64 miles of railway tracks serving 2.2 million people per day. It is the first railroad operator in Japan to have reached 100% clean energy. The company says the carbon dioxide reduction is equal to the annual average emissions of 56,000 households. According to AP, the train operator paid an undisclosed amount to Tokyo Electric Power Co. (TEPCO) for certification of its use of renewables. The renewable sources used for Tokyu’s operations include hydropower, geothermal, wind, and solar according to TEPCO. Tokyu Assistant Manager Yoshimasa Kitano said, “We don't see this as reaching our goal but just a start.”
