Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them. Natural gas 87.9

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Carbon dioxide emissions, including emissions from developing, processing, and transporting the fuels, are shown in orange.

IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. In 2021 alone, China’s CO 2 emissions rose above 11.9 billion tonnes.

Rhodium Group estimates US GHG emissions rose 1.3% in 2022

Green Car Congress

Despite efforts to continue stimulating the US economy in the wake of the pandemic, high inflation put a damper on economic growth, which was exacerbated by a spike in oil prices as a result of Russia’s invasion of Ukraine. Outside of the power sector, emissions increased slightly. Consequently, the US economy grew 1.9%
