Earth friendly railway use? If 10 percent (the airplane and the passenger car) is changed into the railway, carbon dioxide of 12.32 million tons is reduced.

It increases by as much as 8% in the latest data though it is obligated to the amount of the exhaust of carbon dioxide in Japan to decrease 6% from a common will of decreasing carbon dioxide internationally more than the standard in the decided Kyoto Protocol. Especially, 43% and great increases are shown in the traveler section. As for the passenger car and the airplane that accounts for 90% of the traveler section, the number of users has increased, and as much as 53% of the amount of the exhaust of carbon dioxide (passenger car 52.6% and airplane 53.2%) will increase in the past 12 years.

In the trial calculation of "Climate network", it was clarified to lead to the reduction of the carbon dioxide of 12.32 million tons a year that hit 7.7% in the traveler section and 1% of the amount of a total exhaust in Japan when 10 percent of the user of the passenger car and the airplane used the train service instead in the entire Japan. In addition, passenger cars are 9.5 times the railway to the carbon dioxide exhausted when one user is carried by one kilometer, and it has been understood that the airplane reaches 5.8 times.

Oxygen reduction amount trial calculation of two oxidations when use of airplane and passenger car is shifted to railway by 10 percent

It is called in the climate network, "As for going out during summer vacation etc. , it wants you to use an environment friendly railway as much as possible and to cooperate in the global warming prevention".

When release is seen, it proposes "Social cost to an environment-friendly railway is reexamined and the state 'The railway is cheaper' is made" and "Make of the plan and the report of conservation of energy and the CO2 reduction concerning the movement and the transportation of the person of the business trip to the enterprise more than an introduction of the carbon-emissions tax, a taxation strengthening to the jet fuel oil, and a constant scale etc. restrict", etc. as a concrete strategy.

The way of introducing the tax, making up the state "XXXXXX Using it is more profitable", and prompting the spread from the viewpoint of the cost performance looks like well for the current state that the oil substitution fuels such as solar batteries and the biomass fuels relatively become cheap the crude oil amount now and the research came to be done actively.

Rail system to which disused line is especially successive from deterioration of cost-effectiveness in local local line. The management of doing legal restrictions and the change like the above-mentioned or such routes might come to be reviewed.
