A team of researchers in China suggest that, in the context of promoting the use of clean fuel vehicles and increasing vehicle fuel efficiency, CO 2 emissions of China’s urban passenger transport sector could reach a peak of 225 MtCO 2 in 2030. A paper on their study appears in the journal Energy Policy.

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses. However, residential uses and exports of natural gas were not considered in those comparisons.

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. The transportation sector remains the largest source of GHG emissions in the state, and saw a 1% increase in emissions in 2017. Overview of GHG Emissions from the Transportation Sector.

Among the findings of the EIA analysis: CO 2 emissions form natural gas surpassed those from coal in 2016. Natural gas CO 2 emissions have increased every year since 2009. The natural gas share of electricity generation has grown as the coal share declined, partially offsetting the decline in energy-related CO 2 emissions from coal.

US greenhouse gas emissions by gas. The US Environmental Protection Agency (EPA) released its 19 th annual report of overall US greenhouse gas (GHG) emissions, showing a 3.4% decrease in 2012 from 2011. Total emissions of the six main greenhouse gases in 2012 were equivalent to 6,526 million metric tons of carbon dioxide.

Of the four end-use sectors, only transportation emissions increased in 2015 (+2.1%). Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation.
