据今日油价7月15日报道称，美国能源情报署（EIA）周一发布的一份新报告显示，随着煤炭衍生能源的减少，天然气衍生能源的发展，该机构预测，2019年美国的二氧化碳排放量将会下降。

前一年，美国与能源有关的二氧化碳排放量增加了2.7％。

EIA在其最新报告中解释说，通常情况下，每年第一季度的二氧化碳排放量是最高的，并决定了今年剩余时间内与能源相关的二氧化碳排放量的趋势。但是这在短短的几年内发生了变化。今年剩下的九个月与第一季度设定的趋势相反。

EIA预测，2019年将是罕见的年份之一。因此，虽然2019年第一季度的二氧化碳排放量与2018年相仿，但EIA预计，2019年的总排放量实际上将低于2018年。

EIA之所以对降低二氧化碳排放持乐观态度，是基于今年剩余时间对温和温度的预测，预计这将使能源需求低于2018年。

EIA预测，2019年煤炭的二氧化碳排放量将减少1.69亿吨，这是自2015年以来最大的降幅。

U.S. Sees Rare Fall In Energy-Related CO2 Emissions In 2019

The decrease in coal-derived energy in favor of natural gas-derived energy has the Energy Information Administration (EIA) forecasting that the CO2 emissions in the United States will fall in 2019, according to a new report by the agency on Monday.

In the year prior, energy-related CO2 emissions in the United States had increased by 2.7%.

Typically, the first quarter of the year is the highest, and sets the trend for energy-related CO2 emissions for the rest of the year, the EIA explained in its latest report. But in just a handful of years,the remaining nine months of the year bucked the trend set in the first quarter.

The EIA is forecasting that 2019 is one of those rare years. So while the first quarter 2019 CO2 emissions mimic 2018 first-quarter emissions, the EIA is expecting that the overall 2019 emissions will actually be lower than in 2018.

The EIA is basing this optimism for lower CO2 emissions on the mild temperature forecasts for the remainder of the year, which it expects will keep energy demand below that of 2018.

“EIA forecasts that CO2 emissions from coal will decrease by 169 MMmt in 2019, the largest decrease in CO2 emissions from coal since 2015,” the EIA said.
