The Japanese government has launched(发起)a campaign encouraging people to go to bed and get up extra early in order to reduce household carbon dioxide emissions(二氧化碳排放). The Morning Challenge campaign，put forward by the Environment Ministry, is based on the idea that swapping late night electricity for an extra hour of morning sunlight could greatly cut the nation’s carbon footprint． A typical family can reduce its carbon dioxide footprint by 85 kg a year if everyone goes to bed and gets up one hour earlier，according to the campaign．The amount of carbon dioxide emissions potentially saved from going to bed an hour early was equal to 20 percent of annual emissions from household lights，“Many Japanese people waste electric power at night time，for example by watching TV until very late,”a ministry spokesman told The Daily Telegraph.“But going to bed early and getting up e  arly can avoid wasting electrical power which causes carbon dioxide emissions.” The campaign also proposes that people take advantage of an extra hour of morning sunlight by improving their lifestyles in general by running, doing yoga and eating a nutritious breakfast.It is the latest action dealing with climate change by the Japanese environment ministry，which is faced with the challenge of reducing carbon dioxide emissions by 25 percent from 1990 levels within the next decade． It was the same government department that launched the Cool Business cam  paign five years ago, which encouraged workers to wear short—sleeved shirts and offices not to turn air conditioning lower than 28 degrees during the summer.小题1:.
