US Carbon Emissions Rise in 2018 Because of Industry, Fuel Demand
After falling for three years, carbon emissions in the United States rose in 2018.
That information is based on early estimates from an independent research group.
The Rhodium Group studies U.S. emissions of carbon dioxide, a gas linked to rising temperatures in Earth's atmosphere. Its new report estimates that the country's carbon emissions increased 3.4 percent last year. This would be the largest yearly increase since 2010, when the nation was recovering from a financial crisis known as Great Recession.
The research also suggests that the American coal industry continues to struggle because of low-cost, plentiful natural gas.
Bad news for coal
The Rhodium Group reports that coal-fired power stations that produced a total of 11.2 gigawatts of power had closed by last October. Even more were expected to have closed over the following months. If confirmed, that would make 2018 the biggest coal plant closure year on record.
Natural gas is now by far the energy of choice in the United States. The report credited gas for an increase of 166 million kilowatts an hour through October.
American power consumption - and carbon emissions - increased in 2018. The transportation industry was largely responsible for the nation's record emissions.
Demand for gasoline -- the fuel used in most motor vehicles -- decreased. But increases in the demand for other fuel, such as diesel and jet fuel, made transportation the industry most responsible for U.S. carbon emissions.
The report said another big producer of carbon emissions is the construction industry. Emissions from buildings and homes also were up last year, partly because of very cold winter weather in parts of the country.
The Paris question
The Reuters news agency reported last week that the U.S. Environmental Protection Agency did not answer its questions about the report.
Trump administration officials have said that carbon emissions can change from year to year because of economic conditions. They said the country could both cut emissions and enjoy a strong economy at the same time.
Environmentalists say the Trump administration needs to speed up development of renewable energy, manufacturing power from wind and the sun's energy.
The country's carbon emissions had been decreasing year by year since 2015, as the nation worked to honor the Paris Agreement on climate change. But even with those reductions, the United States was unable to meet reductions agreed to by the administration of former President Barack Obama.
Officials from almost 200 countries gathered at United Nations' headquarters in 2016 to sign the climate agreement. Under the deal, the United States promised to cut its carbon emissions by at least 26 percent from 2005 levels by the year 2025.
But in June 2017, President Donald Trump announced his decision to withdraw from the deal. The U.S. will officially withdraw in 2020.

荣鼎咨询公司研究美国排放的二氧化碳，这种气体与地球大气温度上升有关 。该公司的新报告估计，美国去年的碳排放量增加了3.4%，这将是2010年以来最大的年度增幅，当时美国正从一场名为“大衰退”的金融危机中复苏 。
荣鼎咨询公司报告称，截至去年10月，总产能为11.2千兆瓦的煤电厂已经关闭 。在接下来的数月里，预计将有更多的煤电厂倒闭 。如果得到证实，这将使2018年成为有史以来煤电厂关闭最多的一年 。
目前，天然气是美国的首选能源 。该报告将10月份电力每小时增加1.66亿千瓦归功于天然气 。
2018年美国的电力消耗和碳排放均有所增长 。交通运输业是美国创纪录排放量的主要因素 。
大部分机动车辆使用的汽油燃料需求有所降低，但是对柴油和航空燃油等其他燃料的需求有所上升 。交通运输也因此成为美国碳排放量的主要来源 。
该报告称，另一个碳排放大户是建筑业 。去年建筑物和住房的碳排放量也有所上升，部分原因是该国部分地区的冬季天气非常寒冷 。
特朗普政府官员表示，每年的碳排放量会因经济状况发生变化 。他们表示，美国可以在减少排放的同时享受强劲的经济 。
美国的碳排放量自2015年后逐年下降，当时该国正致力于履行《巴黎气候协定》 。但是即使有所成效，美国也无法满足前奥巴马政府达成的减排目标 。
2016年，来自近200个国家的官员在联合国总部签署气候协议 。根据这项协议，美国承诺到2025年，将碳排放量从2005年的水平减少至少26% 。
但是，2017年6月，特朗普总统宣布决定退出该协定 。美国将在2020年正式退出 。
