Earth hour 2015 (Saturday) on March 28, was held at 8:30. In response to a global response to climate change, the theme of this year, earth hour in China will continue to focus on the current the most urgent environmental issues, the most closely watched - fog haze, "can you see the blue" initiative.

　　"Can see blue, represents our Suggestions and expectations for the future. 'to', means that renewable energy can bring about change," blue "on behalf of each of us to say goodbye to the fog haze, looking forward to recover the blue sky." WWF China 'director-general, said the deepening earth hour 2014 "blue sky from" theme, on the basis of this year, earth hour will focus on energy issues, is committed to promoting the mainstream application of renewable energy.

　　The overuse of fossil fuels, is the main culprit of local air pollution at present in China, is also the most main reason lead to global climate change. China is now consumes about half us to say goodbye to the fog haze, looking forward to recover the blue sky." WWF China 'director-general, said the deepening earth hour 2014 "blue sky from" theme, on the basis of this year, earth hour will focus on energy issues, is committed to promoting the mainstream application of renewable energy.

　　The overuse of fossil fuels, is the main culprit of local air pollution at present in China, is also the most main reason lead to global climate change. China is now consumes about half of the coal. In 2012, because of a PM2.5 coal consumption, so2 and nox emissions of China respectively 62%, 93% and 70% of the total pollutant emission. At the same time, the intergovernmental panel on climate change (IPCC) released at the end of 2014 the fifth comprehensive climate change assessment report, further confirmed the greenhouse gas emissions and other human activities since the middle of the 20th century is the main reason for the observed warming, co2 concentration has risen to unprecedented levels since the past 800000 years, and the use of fossil fuels is a major source of carbon dioxide.

　　"WWF believes, energetically develop renewable energy is solve the serious problem of air pollution and global climate change, the ultimate solution." 'we pointed out that "only controlling the total coal consumption and to energy structure dominated by renewable energy, we can say goodbye to haze, finally embrace the blue sky."

　　2015年地球一小时将于3月28日(星期六)晚8:30举行。为响应全球应对气候变化的主题，今年地球一小时在中国将继续聚焦当前最急迫、最受关注的环境议题——雾霾，发出“能见蔚蓝”的倡议。

　　“能见蔚蓝，代表了我们的建议和对未来的期待。’能’，意味着可再生能源能够带来改变，‘蔚蓝’代表我们每个人对告别雾霾、寻回蓝天的期待。”WWF中国总干事卢思骋表示，在深化2014地球一小时“蓝天自造”主题的基础上，今年的地球一小时将聚焦于能源议题，致力于推动可再生能源的主流化应用。

　　化石能源的过度使用，是目前中国局地空气污染的罪魁祸首，也是导致全球气候变化最主要原因。中国正消耗着全球约一半的煤炭。2012年，因煤炭消费的一次PM2.5、二氧化硫和氮氧化物排放量分别占中国污染物排放总量
