CO2 reduction in practice
Transport
The example of Japan Railways East shows that efficiency improvements
are also possible in the public transport sector. JR East mainly operates
electric trains. Compared to railway cars they introduced 10 years
ago, the latest series of rolling stock has 30% lower power consumption,
primarily as a result of weight savings. The company is achieving similar
improvements in its diesel trains. Overall, JR East is aiming to
reduce both its energy use per unit transport and CO2 emissions from its
power plants by 10% by 2001. Furthermore, the company utilises a solar
water heating system, has installed solar electric cells on the roof of
Tokyo railway station, is testing a fuel cell power system and
investigating the introduction of wind power.
