據彭博社8月11日消息：美國能源行業的溫室氣體排放量有望達到30多年來的最高水平，因為公用事業越來越多地轉向煤炭，以推動新冠肺炎疫情后的經濟復蘇。

　　政府周二公布的數據顯示，今年的碳排放量將增加7%，至48.9億噸，至少是1990年以來的最大增幅。煤炭在美國電力結構中的份額將從去年的20%增加到23%，因為天然氣價格高企促使公用事業單位燃燒更多這種污染最嚴重的化石燃料。

　　在這份報告發布之前，聯合國周一發表了一份具有里程碑意義的文件，警告稱，如果不采取嚴厲措施遏制碳排放，未來20年地球氣溫將上升1.5攝氏度(2.7華氏度)，從而引發全球氣候模式的災難性變化。

　　U.S. Energy Emissions Set to Surge Most in More Than 30 Years

　　Greenhouse gas emissions from the U.S. energy industry are on track to surge the most in more than three decades as utilities increasingly turn to coal to power the economic recovery from the Covid-19 pandemic.

　　Carbon emissions will swell 7% this year to 4.89 billion metric tons, according to government data released Tuesday, the biggest increase since at least 1990. Coal’s share of the U.S. power mix will increase to 23%, up from 20% last year, as high natural gas prices prompt utilities to burn more of the dirtiest fossil fuel.

　　The report follows a landmark United Nations paper Monday warning that without drastic efforts to curb carbon emissions, the planet is on track to warm by 1.5 degrees Celsius (2.7 degrees Fahrenheit) over the next two decades, triggering catastrophic shifts in global weather patterns.
