75Modern diesels pollute over 20% less than those from 10 years ago

Today, if you're a car company and you offer a diesel engine in this market, you have to go to great lengths to show consumers that it's less harmful to the environment than a gas-powered engine. That's why marketing types have come up with TDI Clean Diesel and EcoDiesel and BlueTec and so on, rather than just plain old "diesel." How much cleaner are today's oil burners, though?

22Traffic pollution exposure linked to autism in young children

Living close to highways has built-in health hazards. According to the Centers for Disease Control and Prevention, asthma and carbon monoxide poisoning are two major public health problems caused by air pollution. Now, autism could be added to the list.

80Greenhouse gas levels still climbing, CO2 now up to 389 ppm, says UN

It's got to be difficult to accurately measure and predict the amount of greenhouse gases in the atmosphere, but if tests by the World Meteorological Organization (WMO) are correct, then things are getting worse than people originally thought.

AddIs carbon fiber really a "green" solution to reduce vehicle weight?

BMW and Mercedes are leading the way in using carbon fiber to reduce weight in future passenger vehicles. Losing pounds can also be key to meet upcoming CAFE regulations and can also help increase the range electric vehicles can travel. The shift towards carbon fiber will probably become more widespread throughout the automotive industry as companies realize the weight-saving benefits of this product versus steel. Though carbon fiber is touted for its low weight, a new report by Toyota and repor

AddTexas files petition to review EPA's CO2 'endangerment finding'

Last spring, the EPA ruled that it could regulate CO2 and five other greenhouse gases under the Clean Air Act because they are could be harmful to the health of humans. Automakers quickly responded by saying they hoped the finding wouldn't stop efforts to find a nationwide regulatory environment for emissions. In December, the EPA announced that, indeed:

AddCattle industry has a beef with EPA over greenhouse gases

To the surprise of many, the vast majority of the automakers that sell their wares here in the United States welcomed the EPA's decision earlier in the year that carbon dioxide and other greenhouse gases are damaging to the environment and should therefore be regulated. That has plenty to do with the desire for a single national fuel mileage standard. But transportation certainly isn't the only way we generate greenhouse gases as a society.

AddLet's Make a Deal: Automakers reportedly reach agreement with lawmakers on carbon cap legislation

Now that the U.S. has officially concluded that greenhouse gasses are harmful to human health, it's time to do something about them. One major hurdle standing in the way of the U.S. implementing carbon cap and trade legislation appears to have been cleared as both the domestic automakers and Michigan's legislature have lifted their opposition and now support for the bill. Why? The Detroit News reports that an agreement has been reached that could see up to $15 billion paid out to the Detroit-bas

AddEU calls for new eco-friendly air conditioners by 2011

Following a directive first created back in 2006, the European Union has passed down a ruling that would force European automakers to find a new refrigerant to use in their vehicle's air conditioners. There's some debate as to the timing of this mandate, as it's no secret that most automakers are in a fight to just remain in business.

AddAuto Alliance responds to EPA's CO2 warning

Today's EPA's decision to put CO2 on the list of greenhouse gases that endanger human health sets up a totally predictable confrontation with the Auto Alliance. The reason is that if CO2 can be regulated, then there is the potential for individual states (i.e., California) to enact their own greenhouse gas regulations. This, of course, could result in the Alliance's dreaded "patchwork" situation. So, it's no surprise that the Alliance would want to chime in on the decision, and we just got a sta

AddEPA Administrator declares that CO2 CAN'T be considered for power plants!

With just weeks to go before the Bush administration cedes power, executive orders and regulatory decisions gutting all sorts of federal rules are flying out from Washington. One of the most recent has come from the office of EPA administrator Stephen Johnson. Johnson has decreed that the agency CANNOT consider greenhouse gas emissions in determining whether to grant permits for new power plants. This goes well beyond the Agency's previous neglect of the issue and actively prevents considering t

AddItaly not on board with French/German CO2 agreement

My, how the tables have turned. First, it was Germany that was in opposition to stringent emissions standards in the European Union which would have regulated the amount of carbon dioxide a vehicle can emit, beginning in 2012. German automakers tend to make large, luxurious vehicles with big, powerful engines. France, though, did not want to see changes made to the regulations, as its automakers already were close to meeting the proposals and thought it would be unfair to make concessions just f

AddAutomakers work on sustainable air conditioning

It wasn't all that long ago that the auto industry was under fire for its use of ozone-depleting chemicals in its air conditioning systems. To curb those fears, the older R-12 refrigerant was replaced with R-134a refrigerant. Interestingly enough, CO2, long associated with harmful automobile emissions, is being touted as a desirable natural replacement for the chemical substances used today. In fact, the German Automotive Association has already chosen to use CO2 as the next source for automotiv

AddFiat declared lowest CO2 automaker in Europe

Automotive research and analysis firm JATO does an annual assessment of vehicle carbon dioxide emissions in the European Market. For several years, Fiat and Peugeot/Citroen have been going back and forth as the leader. For 2007, JATO's analysis based on sales put Fiat at the top of the heap among the ten biggest manufacturers that do business in Europe. Fiat's 2007 fleet averaged CO2 emissions of only 137.3g/km while second place was a draw between Peugeot and Toyota at 141.9g/km. Peugeot and Fi

43Speed bumps are bad for the planet

Britain's Automobile Association has found another bump in the road to environmental kindness: speed bumps and really low speed limits. They took a car that got 58-mpg running a constant 30-MPH, and ran it over speedbumps at the Millbrook Proving Ground, slowing down and speeding up for each bump. What they discovered was that mileage dropped to 31-mpg and carbon dioxide emissions went up. The findings correlate with those of the country's Transport Research Laboratory, which reported that "carb

46California set to sue EPA next week

EPA standards govern vehicle emissions such as NOx and hydrocarbons. They are byproducts of combustion that can be balanced with engine tuning, such as ignition timing and fuel delivery. They can also be reduced through devices such as catalytic converters. Catalytic converters cause a chemical reaction that converts carbon monoxide into carbon dioxide and hydrocarbons into carbon dioxide and water. However, earlier this year the EPA won a Supreme Court ruling adding carbon dioxide to the list o

1Porsche Cayenne, Panamera getting hybrid power

Automakers and legislators in Europe are tightening the screws on CO2 emissions, and Porsche may turn to hybrid powertrains for the Cayenne and Panamera to meet a proposed 130 gram per kilometer limit. Bosch and Audi are reported partners in the effort to bring a gasoline/electric system to the Cayenne before 2010, with the Panamera falling in line, as well. While hybrid technology is typically used to boost fuel economy, the V8 and large vehicle size of the Porsche models are anathema to the st

20Supreme court says EPA can regulate greenhouse gases

Admittedly, we're a little late to the party on this one, but thankfully, our greener sibling site was on top of things when the Supreme Court made an important ruling yesterday regarding the Environmental Protection Agency's enforcement of the Clean Air Act.
