中美減排計劃令人期待全球協議
The US and three big emerging market countries have bolstered hopes for a global climate change deal this year by unveiling fresh plans to curb greenhouse gas emissions.
美國和三大新興市場國家公佈了限制溫室氣體排放的最新計劃，從而增強了在今年達成一項全球氣候變化協議的希望。In a day of cascading announcements in capitals around the world, the presidents of the US and Brazil jointly announced plans to each generate 20 per cent of their electricity from non-hydropower renewable sources, such as wind and solar power, by 2030.
世界各國在同一天接連作出宣佈，美國和巴西總統共同宣佈，將各自在2030年前讓非水力可再生資源（例如風能和太陽能）發電量佔到總髮電量的20%。
Separately, China, the world’s biggest carbon polluter, and South Korea formally submitted climate change plans to the UN for a December meeting in Paris where countries are due to finalise an international global warming agreement.
另外，全球最大碳排放國家中國以及韓國正式向聯合國12月巴黎大會遞交氣候變化計劃，各國將在此次會議上敲定一項國際全球變暖協議。
China said it would cut its carbon emissions per unit of gross domestic product by 60-65 per cent from 2005 levels by 2030. This followed earlier commitments that its carbon emissions would peak no later than 2030 and the amount of non-fossil fuels in its energy mix would rise to about 20 per cent by 2030.
中國表示，到2030年，將把單位國內生產總值(GDP)的碳排放從2005年水平降低60%至65%。這延續了早先的承諾，即中國的碳排放將不遲於2030年見頂，同時到2030年，非化石燃料在其能源結構中所佔比重將升至20%左右。The pledges would mean the US tripled the amount of renewable power on its grid, while Brazil would more than double its share. Brazil also said it would restore 12m hectares of forest by 2030, an area nearly the size of England.
這些承諾將意味着美國的可再生能源發電量將增加兩倍，巴西將增加一倍多。巴西還表示，將在2030年前恢復1200萬公頃的森林，幾乎相當於英格蘭的面積。The combined pledges mean countries accounting for more than 70 per cent of global greenhouse gas emissions have now set out their plans for the Paris meeting. Large economies including India, Japan and Australia have yet formally to table their plans.
這些國家的承諾意味着，佔全球溫室氣體排放70%以上的國家已向巴黎氣候大會提交計劃。大型經濟體中還有印度、日本和澳大利亞等國尚未正式提交計劃。
