The U.S. Energy Information Administration is estimating that natural gas will be the second-largest source of new U.N. carbon emission in 2020, a significant jump from 2015, when natural gas accounted for less than 1 percent of global emissions.
The EIA projects that by 2040, the U.F.O. carbon intensity of natural gas is expected to surpass that of coal and that it will outpace other fuels such as oil, natural gas and natural gas liquids by nearly 50 percent, according to a study released Wednesday by the Energy Policy Institute and the Center for American Progress.
Natural gas will generate more than a third of the global greenhouse gas emissions in 2020.
A key metric of natural-gas emissions is the CO2 emitted by each ton of CO2 produced, which is calculated by adding up the energy intensity of each barrel of natural oil and natural coal.
In 2020, the EIA expects natural gas to make up nearly half of the total emissions of the UF.
Oceans are the largest carbon sinks, accounting for nearly 18 percent of total global carbon dioxide emissions in 2016, according a 2016 study by the U-M Center for Global Ocean Systems.
While natural gas emits more CO2 per barrel than any other fuel, its emissions are far lower than that of oil and coal, the study said.
To help power the economy, the new study says it would be good for the U,F.
and OCOEs to boost energy efficiency, curb energy use, and support renewable energy.
