A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. A TWP >1 means that the cumulative radiative forcing from choosing natural gas today is higher than a current fuel option after t yr. Click to enlarge.
To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.
The Alternative and Renewable Fuels and Vehicle Technology Program’s Investment Plan allocates $176 million over the next two years to stimulate green transportation projects and encourage innovation to help meet the state’s aggressive climate change policies.

The technology pathways are intended to show the different cost impacts of achieving different levels of stringency, if the industry were to place more or less emphasis on hybrids, plug-in hybrids, and electric vehicles as compared to advanced gasoline technologies and vehicle mass reduction. hybrids, and electric vehicles.
On average, a 25% reduction in carbon dioxide equivalent (CO2-eq) emissions can be expected on a well-to-wheel (WTW) basis when replacing gasoline by light-duty vehicles (LDVs) running on compressed natural gas (CNG). Tags: Climate Change Emissions Heavy-duty Natural Gas.
EPA’s analysis shows manufacturers can comply with the final standards with modest increases in the numbers of electric vehicles entering the fleet. As the GHG standards get stronger over four years, sales of EVs and plug-in hybrid vehicles will grow from about 7% market share in MY 2023 to about 17% in MY 2026, the agency projects.
The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. The implication for biofuels is important, to the extent they are aimed at meeting climate and petroleum use reduction goals. —Meier et al.
However, widespread commercial use of electric drive on long-haul and heavy-duty routes is not yet feasible. This is where sustainable fuels play a crucial role as they could be pivotal in reducing the climate impact of transport emissions. Liquefied natural gas (LNG) and compressed natural gas (CNG) are considered alternative fuels.
Funny that this article cites “a shortage of public charging stations&# as the sole reason for auto makers scrapping electric vehicles in the 1990s. Read more about it in the San Jose Mercury News Article: Reservations for the all-electric Nissan Leaf start Tuesday. Reservations for the all-electric Nissan Leaf start Tuesday.
According to a report by Smart Energy Decisions , there were more than one million electric vehicles (EVs) in commercial and government fleets in the United States as of 2021, up from just over 300,000 in 2019. Many companies have made commitments to transition portions of their delivery fleets to electric over the next five to 10 years.
The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.
