Obama's new pollution measure 奧巴馬宣布美國(guó)減排新規(guī)

媒體英語(yǔ)會(huì)帶大家一起學(xué)習(xí) BBC 撰稿人在報(bào)道世界大事時(shí)常用到的單詞和短語(yǔ)。

美國(guó)政府將公布一項(xiàng)減碳計(jì)劃來限制其火力發(fā)電廠的碳排放。這將是美國(guó)有史以來為緩解全球氣溫變暖而采取的最重要的行動(dòng)之一。以下是 BBC記者 Beth Mcleod 發(fā)回的報(bào)道：

The United States produces more greenhouse gases than any country in the world, apart from China. The plan to curb emissions from fossil-fuelled power plants is the most ambitious measure proposed by President Obama in his efforts to tackle climate change.

The details of the plan will be laid out by the Environmental Protection Agency. It will give broad flexibility to states to decide how to meet carbon reduction targets, whether by closing coal-fired power stations and switching to cleaner sources of energy, or by creating cap-and-trade schemes.

Some US media are reporting that by 2030 the government wants a 30% reduction in carbon dioxide emissions. Business groups and Republicans fiercely oppose the new regulations, and say they're likely to drive up electricity prices. But for the president the measure is important for his environmental legacy and in order to show global leadership on climate change.
