The new prime minister announced the aim for a 25% reduction in Japan’s greenhouse-gas emissions from 1990 levels by 2020.
How to do it? From an article from Takamitsu Sawa in Japan Times, Monday October 12, 2009.
– Population -2% from 1990 level = -5 emission cut?
– use of eco-friendly products
Example of iMev electric car of Mitsubishi Motors: it covers 10 kilometers on 1 kilowatt-hour of electricity. Existing power stations in Japan discharge about 450 grams of CO2 to generate 1 kilowatt-hour of electricity. A typical car emits 2300 grams of CO2 for every 10 kilometers on 1 liter of Gasoline.
– Promote “feed-in-tariff”: Power companies are required to purchase surplus electricity generated by by privatehomes using solar and other renewable energy sources at above-market prices set by the government (as in Germany?)
– An emission trading system should be adopted soon. The concept of carbon pricing has already been accepted by major inductrialized nations. The EU adopted emissions trading in 2005. US to follow soon.
