Before a gathering at a distribution warehouse in Maryland, United States President Barack Obama announced that his administration has set March 2016 as the deadline for the next round of fuel efficiency and emissions standards for medium and heavy trucks to meet compliance.

Bloomberg reports President Obama’s latest initiative — part of his overall strategy regarding energy security and climate change — will bring “thousands of dollars of savings every year” for truck operators while also benefiting the economy via lower costs for consumer goods and new technology development. Both the Environmental Protection Agency and the National Highway Traffic Safety Administration will issue a Notice of Proposed Rulemaking regarding the new standards by March 2015.

Industry groups in general were supportive of the announcement, which will also see manufacturers working with the federal government on bringing new trucks up to the new standards, though American Trucking Association president Bill Graves urged the Obama administration to proceed with caution by setting forth a path “that is both based on the best science and research available and economically achievable.”

Moving forward from 2016, the next set of standards to come into force by 2018 and beyond will see the industry aggressively use technology — especially in the use of aerodynamics — to meet the fuel economy standards set at that time,.

Forbes Lists “America’s Dirtiest Cars” http://www.thetruthaboutcars.com/2009/11/forbes-lists-americas-dirtiest-cars/ http://www.thetruthaboutcars.com/2009/11/forbes-lists-americas-dirtiest-cars/#comments Thu, 12 Nov 2009 17:25:44 +0000 http://www.thetruthaboutcars.com/?p=335119 Take that, Mother Nature!

There’s all kinds of controversy over what makes a car “green” and what doesn’t. Some point to size and efficiency, crucifying Hummers and full-size trucks as criminals against the planet. Others point to lifecycle greenhouse gas emissions, battery-component mining pollution and other less-obvious measures to excoriate hybrids. In any case, TTAC’s scientific department isn’t well-funded enough to issue a comprehensive report on the subject. Forbes may not have tested cars itself, or dug into true “dust-to-dust” footprints, but it’s gone ahead and published a list of “America’s Dirtiest Vehicles” anyway. Let’s take a look, shall we?

The article claims that to search out  “America’s Dirtiest Vehicle” by using air pollution and greenhouse gas emissions data from the EPA. The EPA air pollution data is ranked on a scale of 1 to 10, 10 being the cleanest, 1 being dirty. “Air pollution” criteria are compounds like unburnt hydrocarbons, NOx fumes, particulate matter, carbon monoxide and formaldehyde. And you thought smoking was a dirty habit! Greenhouse gases are done on the same 1 to 10 scale and are evaluated by measuring, carbon dioxide, nitrous oxide and methane emissions, which means the car’s fuel economy comes into play here. Less miles, more fuel burnt. More fuel burnt, more greenhouse gases emitted. In the event of a tie, they used combined fuel consumption figures to break the deadlock.

The article then goes on to its small print, namely, the vehicles which were excluded. Vehicles which were classed as “heavy duty” were exempt from this report because these vehicles aren’t subject to federal fuel economy requirements. Also missing were “super cars”; the reason being that they sell in such small volumes, it’s not worth counting them in. Saabs sell in small numbers, but I bet you they got put in this report.

So after setting out the parameters and established who’s being evaluated and who isn’t, what’s the result?

Well, according to Forbes, America’s dirtiest is . . . the Jeep Grand Cherokee. Yes, for once, Chrysler comes top in a survey. It scored 3 out of 10 for air pollution ratings and 2 out of 10 for greenhouse gas emissions. But the report decided to stick the boot in further buy saying “Even had we included those supercars, though, the Jeep Grand Cherokee still would have topped the chart.” Ouch! Not content with giving the Cherokee a battering, the report then deals its killer blow. “The flex-fuel engine—prized because it uses a renewable resource that reduces dependency on traditional gasoline—on the Cherokee was even worse: three out of 10 and one out of 10 for the air pollution and gas emissions, respectively.” That’s gotta hurt!

It then gets even worse for Chrysler, because not only did they secure top spot by a mile (insert your own MPG joke here), they also got a further four places in top ten. The Dodge Durango came in 10th, the Dodge Ram 1500 came in 9th, the Dodge Dakota came in 8th and the Chrysler Aspen came in 7th.

“We continue to drive our fleet average even lower,” Chrysler spokesman Nick Cappa, who was given the unenviable job of putting a positive spin on this report, said. “Chrysler Group products are 99% cleaner than vehicles of 30 years ago and meet or exceed United States federal emission standards, the most stringent in the world.” Reports of whether Mr. Cappa went into another room and burst into tears are unfounded.

The report then goes on to mention the rest of the top ten. “60% of the entries on our list are from domestic automakers. The remainder are German”. The other “dirty domestic” was the Chevrolet Trailblazer, which came in 4th. The list in full can be seen here.

Chrysler can take some heart in the knowledge that at least their electric and hybrid car plans will give them some much needed green credent—oh. Never mind then.
