Tokyu Railways' Environmental Data and Environmental Accounting
Electricity Consumption
Tokyu Railways's power consumption can be divided into operating power, which is used to operate rolling stock, and incidental power, which is used to operate station facilities, signals, and security equipment.
Changes in electricity consumption and total electricity intensity
Changes in vehicle mileage (business mileage including return trips, etc.)
VVVF-controlled vehicles to reduce power loss in motors
VVVF-controlled trains use inverters to convert the DC current flowing through the overhead wires into an AC current of optimum voltage and frequency to drive the AC motor. This reduces the loss of power. AC motors also have the advantage of being smaller, lighter, and less prone to failure.
Our company was the first in the industry to introduce VVVF-controlled vehicles in 1986. As of April 1, 2023, 99.5% of all vehicles will be VVVF-controlled, and we will continue to introduce VVVF-controlled vehicles in the future in line with vehicle renewals, etc.

Estimated reduction in CO2 (comparison between railroads and private passenger cars)
railway are a form of mass transportation and are said to be environmentally friendly. The amount of CO2 emitted per passenger kilometer traveled by railway is about one-fifth of that emitted by a private passenger car.
Tokyu Lines will transport approximately 9.7 billion passenger kilometers in FY2023, carrying approximately 1.05 billion passengers per year, covering approximately 9.3 km per trip (for reference, 9.4 km between Shibuya Station and Futako Tamagawa Station on Den-en-toshi Line). From April 1, 2022, all Tokyu Lines will be operated on 100% renewable energy with virtually zero CO2 emissions. This is the first initiative in Japan to operate an entire railway line on 100% renewable energy. The amount of CO2 emitted when traveling 9.3 km in a private car is 1,228 g of CO2.
Carbon dioxide emissions per unit of transport volume (passengers FY2022)
Environmental Accounting
We conduct environmental accounting as a means of understanding the "cost of environmental conservation," the resulting "environmental conservation benefits," and the "economic benefits associated with environmental conservation," and evaluating the effects of environmental conservation through mutual comparison. Environmental accounting for FY2023 complies with the "Environmental Accounting Guidelines 2005 Edition" (Ministry of the Environment) and the "Private Railway Business Environmental Accounting Guidelines 2008 Edition" (The Association of Japanese Private railway).
Collection period: April 1, 2023 to March 31, 2024
