New fuel efficiency and greenhouse gas emissions standards for heavy-duty vehicles and engines, proposed this summer, have just run the gauntlet of public comment on their way to final adoption next year. As proposed, these Phase 2 standards would provide major gains in fuel efficiency for heavy-duty vehicles by 2027.
Recently, the Department of Energy (DOE) and the White House Office of Science and Technology released the second Quadrennial Technology Review, or QTR. The 489 page tome bears resemblance to many other government reports that are too often relegated to the TL;DR file—too long; didn’t read. That would be unfortunate for those of us who care about the future of energy efficiency technologies.
On September 18th, the Environmental Protection Agency issued a notice of violation of the Clean Air Act to Volkswagen for including software in their diesel vehicles that helps circumvent EPA emission standards for nitrogen oxides. As a result, greenercars.org has suspended Green Scores for the affected vehicles until further notice as these scores are no longer valid. Read more at greenercars.org.
Efforts to reduce energy consumption in the transport of goods often run up against the demand for speed, convenience, flexibility, and security. Send a shipment by energy-intensive air or truck if it is valuable or time-sensitive – rail or water will do if it’s not. The fundamental tension in moving goods today is between individualized treatment for each shipment and the efficiency of the system as a whole. But information and communications technologies (ICT) are increasingly offering ways to avoid that tradeoff.
In 2011, the EPA and NHTSA adopted the first-ever fuel efficiency and greenhouse gas emissions standards for medium- and heavy-duty vehicles and engines built for the 2014 to 2018 model years. Those standards, although not demanding enough to promote adoption of all available efficiency technologies, will benefit truckers and consumers and save over a half-million barrels of oil per day by 2030.
Last week a National Research Council (NRC) committee on heavy-duty vehicles released a report on technological, market, and regulatory factors relevant to the upcoming Phase 2 heavy-duty vehicle fuel efficiency and greenhouse emissions standards.
The president recently announced that a second phase of fuel efficiency and [no-glossary]greenhouse gas[/no-glossary] standards for heavy-duty vehicles will be proposed in March of 2015, with rule adoption a year later. Some aspects of the program are likely to change from the first phase of the standards.
Greenercars.org Releases 2014 Environmental Scores: Smart ForTwo Electric Drive Tops Greenest Vehicles List
Washington, D.C.—Looking forward to vehicle sales above 16 million in 2014 for the first time in seven years, automakers are capitalizing on the market upswing by offering customers a vast array of vehicle options. Today, at greenercars.org, ACEEE released its 17th annual comprehensive environmental ratings for vehicles.
[no-glossary]Heavy-duty vehicles consume 2.9 million barrels per day of petroleum fuels in the United States today. In 2011, the National Highway Traffic Safety Administration and the Environmental Protection Agency adopted standards to reduce the fuel consumption and greenhouse gas emissions of heavy-duty vehicles in model years 2014–2018.
New Mitsubishi i-MIEV Unseats Honda Civic Natural Gas after 8 Consecutive Years at the Top
Washington, D.C.—With the auto industry back on its feet and fuel economy standards shifting into high gear, automakers provided American consumers with a huge array of vehicles and technologies to choose from in 2012. Today at greenercars.org, the American Council for an Energy-Efficient Economy (ACEEE) released its 14th annual comprehensive environmental rankings showing how these offerings stack up.
