Feds Issue GHG Emissions, CAFE Standards Diesel engine manufacturers for school
buses were among the first to comment on the release of regulatory guidance last month from the EPA and NHTSA on first-ever standards that aim to reduce both greenhouse gas emissions and set fuel economy levels for medium- and heavy-duty commercial fleet vehicles. School buses fall under the category
“vocational vehicles,” for which EPA and NHTSA proposed a standard of met- rics of grams per ton-mile to account for heavier loads carried by these vehicles that burn more fuel. Te rules are proposed to regulate chassis manufacturers to meet 10- percent additional reductions in emissions levels. EPA and NHTSA noted that these vocation vehicles undergo complex build processes, with an incomplete chassis of- ten built with an engine and transmission purchased from other manufacturers, then sold to a body manufacturer. Cummins Inc. supported the new stan-
dards and announced plans to certify its engines early to meet these standards. Cummins said it has worked proactively on the regulation with a wide range of stake- holders over the past several years and is already developing the clean and efficient technology that will be needed to comply. “Environmental regulations can often
be difficult for industry, adding cost and complexity. So early on, Cummins set out with the goal of helping the government establish a clear, consistent, challenging and enforceable regulation that recog- nizes the needs of business and provides incentives to companies that create in- novative technologies as well as jobs in this country,” said Rich Freeland, Cum- mins vice president and president of the company’s engine business. “Tis regulation will add real value for our cus- tomers as better fuel economy lowers their operating costs while significantly benefitting the environment.” Meanwhile, Navistar released its own
statement that the manufacturer of the MaxxForce diesel engine is in the midst of meeting the standards. “With this rule, EPA and NHTSA have
now set an example for what could be a worldwide GHG and fuel efficiency regu- lation for heavy-duty trucks and engines,” said Daniel Ustian, chairman, president and CEO of Navistar. “As a fuel-efficiency leader, Navistar is always focused on de- livering value to our customers, and we currently have plans in place to continue to support this competitive position by delivering integrated truck and engine technology solutions that achieve maxi- mum fuel economy for our customers. “ Te proposed rules cover not only en- gines but also hybrid powertrains and
tires, the latter accounting for the second largest contribution of energy losses for vocational vehicles, according to EPA and NHTSA. EPA is also proposing standards to cap current NO2 and CH4 emissions
from engines to keep manufacturers from allowing significant emissions increases in the future. Te Union of Concerned Scientists said the new standards could create nearly 80,000 new jobs.
Science Group Warns of ‘Attack’ on EPA Speaking of the Union of Concerned Scientists (UCS), the organization said new legislation in the U.S.
House of Representatives promises to take a “hatchet” to the Clean Air Act. House members were sched- uled to return from recess this month to continue debate on H.R. 2584, a spending bill that outlines the budget for the Department of the Interior and the EPA. UCS called the bill an “all-out attack on our air, water, lands, and wildlife.” According to UCS, the bill includes nearly 40 anti-health, anti-environment amendments—including an amendment that would prevent the EPA from reducing global warming emissions under the Clean Air Act.” Te Clean Air Act was passed 40 years ago to reduce the nation’s pollution levels. UCS added that, as of Aug. 2, the legislation as provided nets health benefits upwards of $50 trillion.

For reliable air conditioning, turn to the people with advanced degrees. Mobile Climate Control offers the most extensive line of split and rooftop AC units to optimize system performance on any school bus, small to large. And they’re all backed by expert support. Maybe that’s why more school buses in North America cool with MCC. Call MCC, 1.800.673.2431. Or visit our Web site. For AC that’s an A+.
