Energy-efficient railcars ■Introduction of Energy-efficient railcars account for 68% of our fleet energy-efficient railcars Conventional railcars JR East continues to introduce energy-efficient railcars such as the E231 and E205. The number of energy-efficient railcars is steadily increasing, '05 Target value : 80％ reaching 68% by the end of FY 2002. p.28 68％ What is environmentally friendly transportation?

To accomplish this, we 100％ developed various technologies, redesigned railcar structure, and used stainless steel instead of iron 205 series when possible to reduce weight. Furthermore, by 66％ harnessing the energy generated during braking, we have greatly reduced overall energy consumption. 209 series These steps achieved significant reduction of CO2 E231 series 47％ emissions. p.28 5 6 JR EAST GROUP JR EAST GROUP.
