U.S. Energy-Linked CO2 Emissions Rose in 2018 for First Time in 2014

Total U.S. energy-associated carbon dioxide (CO2) emissions last year hiked to 5.27 B metric tons, 2.7% more than its previous year level. The primary reasons for the increase were higher natural gas-associated emissions ensuing from more extreme summer and winter weather and development in transportation-related petroleum emissions, linked to a robust economy. U.S. vitality-related CO2 emissions dipped in 6 of the past ten years. They had been 12% lower in 2018 than in 2005, based on a data series revealed in the U.S. Energy Information Administration’s Month-on-Month Energy Review

Coal-linkedCO2 emissions plunged by 4% last year, making coal the only fossil fuel with lower CO2 emissions in 2018 compared with a year prior. Total U.S. emissions from natural gas first exceeded emissions from coal in 2015. Natural gas consumption has increasingly displaced coal consumption in the electrical energy sector in recent years.

Natural gas consumption and emissions increased in 2018, mainly because of colder winter and hotter summer weather. Natural gas is the most prevalent home heating gas, as well as the most pervasive fuel used to generate electricity. Because heating and cooling demand were higher last year, total natural gas emissions rose by 10%.

U.S. petroleum consumption further increased last year, contributing to a 1.9% increase in energy-linked CO2 emissions from petroleum. Comparatively, strong financial growth spurred growth in diesel consumption, which led to a 6% rise in related CO2 emissions.

Total U.S. electricity generation hiked by 3.6% in 2018; however, the electric energy sector CO2 emissions merely increased by 1.1%. In recent times, the U.S. electricity generation mix has moved away from coal and toward natural fuel and renewables.


Peter Leonhard

The group employed Peter Leonhard last year as a column lead. Previously he was leading the Natural Gas column, later took the wheel of Power and Energy column. Peter alongside an associate, looks after the functioning of the column. Right from sourcing information to writing news, they both do it all. Peter is also an environmentalist working on the climate crisis.
