A low-carbon economy (LCE), low-fossil-fuel economy (LFFE),〔(Nanomech in Photovoltaics: Dye Sensitized Solar Cells )〕 or decarbonised economy〔(【引用サイトリンク】title=Decarbonised Economy )〕 is an economy based on low carbon power sources that therefore has a minimal output of greenhouse gas (GHG) emissions into the environment biosphere, but specifically refers to the greenhouse gas carbon dioxide. GHG emissions due to anthropogenic (human) activity are increasingly either causing climate change (global warming) or making climate change worse. Scientists are concerned about the negative impacts of climate change on humanity in the near future. Globally implemented LCEs are therefore proposed by those having drawn this conclusion, as a means to avoid catastrophic climate change, and as a precursor to the more advanced, zero-carbon economy. In terms of large industrialized nations, mainland France, due primarily to 75% of its electricity being produced by nuclear power, has the lowest carbon dioxide production per unit of GDP in the world and it is the largest exporter of electricity in the world, earning it approximately €3 billion annually in sales.〔(【引用サイトリンク】title=Privacy policy )〕 ==Rationale and aims== Nations may seek to become low-carbon or decarbonised economies as a part of a national climate change mitigation strategy. A comprehensive strategy to mitigate, if that is possible, climate change is carbon neutrality and geoengineering. The aim of a LCE is to integrate all aspects of itself from its manufacturing, agriculture, transportation, and power-generation, etc. around technologies that produce energy and materials with little GHG emission, and, thus, around populations, buildings, machines, and devices that use those energies and materials efficiently, and, dispose of or recycle its wastes so as to have a minimal output of GHGs. Furthermore, it has been proposed that to make the transition to an LCE economically viable we would have to attribute a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax. Some nations are presently low carbon: societies that are not heavily industrialised or populated. In order to avoid climate change on a global level, all nations considered carbon intensive societies, and societies that are heavily populated might have to become zero-carbon societies and economies. Several of these countries have pledged to cut their emissions by 100% via offsetting emissions rather than ceasing all emissions (carbon neutrality); in other words, emitting will not cease but will continue and will be ''offset'' to a different geographical area. EU emission trading system allows companies to buy international carbon credits, thus the companies can channel clean technologies to promote other countries to adopt low-carbon developments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Low-carbon economy」の詳細全文を読む スポンサード リンク
