特别策划低碳经济

1、 特别策划低碳经济 a low-carbon economy (lce) or low-fossil-fuel economy (lffe) is a concept that refersto an economy which has a minimal output of greenhouse gas (ghg) emissions into thebiosphere, but specifically refers to the greenhouse gas carbon dioxide. recently. most ofscientific and public opinion ha

2、s come to the conc!usion there is such an accumulation of ghgs(especially c02) in the atmosphere due to anthropogenic causes,that the climate is changing.the over-concentrations of these gases are producing global warming that affects long-termclimate, with negative impacts on humanity in the forese

3、eable future. globally implementedlce´s therefore, are proposed as a means to avoid catastrophic climate change, and as aprecursor to the more advanced, zero-carbon society and renewable-energy economy.the aim of a lce is to integrate all aspects of itself from its manufacturing. agriculture,t

4、ransportation and power-generation etc, around technologies that produce energy and materials with little ghg emission; and thus, around populations, buildings, machinesand devices which use those energies and materials efficiently, and, dispose of orrecycle its wastes so as to have a minimal output

5、 of ghgs. furthermore, it has beenproposed that to make the transition to an lce economically viable we would have toattribute a cost (per unit output) to ghgs through means such as emissions tradingand/or a carbon tax.低碳经济，这个全新的概念，是以低能耗、低污染、低排放为基础的经济模式，是人类社会继农业文明、工业文明之后的又一次重大进步。低碳经济实质是能源高效利用、清洁能源开发

6、、追求绿色gdp的问题，核心是能源技术和减排技术创新、产业结构和制度创新以及人类生存发展观念的根本性转变。随着哥本哈根的全球气候峰会的召开，低碳经济为越来越多的人所认识、了解。这种经济模式必将随着人们对环境的重视程度的加深，慢慢被人们所接受，继而去打造低碳城市。让我们来了解一下这个概念，也为我们的地球出力所能及的一份力吧！让我们来看看，各地的媒体都是怎么说的吧！low carbon economy is the only real choice nicholas stern said that if we continued along the business as usual path t
