While I support the idea of reducing emissions, I think there are better ways to do it than to make mandates like this. Rather, I would prefer to see incentives for the automakers to address all aspects of emissions (not just glass). How about simply tightening overall emission requirements and let the auto makers figure out how to accomplish it. Glass may be one approach but there are certainly others. Sad thing is that most automakers, especially U.S. automakers, have been reactive, not proactive. Companies like Toyota have eaten their lunch. And companies like Tesla have gained real traction. Innovate or die!

Carmakers, cell phone firms complained about sun-reflecting glass

California air regulators voted unanimously Thursday for a mandate requiring auto manufacturers to include sun-reflecting glass on all vehicles sold within the state by 2014.
The move by the California Air Resources Board was intended to keep cars, pickup trucks and sport utility vehicles cooler during hot weather, reducing the use of air conditioning.
That was expected to improve fuel efficiency and reduce greenhouse gas emissions.
"The end result of it is the customer gets a car that's more comfortable to ride in, air conditioners don't have to work as hard, and the atmosphere will be happier because we won't be emitting as much carbon dioxide," said board chairwoman Mary Nichols.
The auto industry complained about the expense but won an extra year to comply with the first phase of the regulation. Automakers also will be allowed to find other ways to cool down cars to avoid a tougher window standard to be phased in after 2014.

Beginning with the 2012 model year, a quarter of passenger vehicles sold in California must have specially coated windshields that block 50 percent of the sun's heat from a parked car. All vehicles must have those windshields within two more years.
In 2016, windshields must block 60 percent of the sun's heat unless car makers can demonstrate other ways to keep cars cool.
The regulation is projected to prevent 700,000 metric tons of carbon dioxide from entering the atmosphere in 2020, the equivalent of taking 140,000 vehicles off the road for a year. There were nearly 22 million passenger vehicles registered last year in California.
The new windows would cool a sedan's interior by an estimated 14 degrees Fahrenheit or 12 degrees for a pickup or SUV.



Cars cause so much damage for our nature. producers generally regret to use tools which can decrease this damage because of its expenses. someone has to tell them harming our nature will result extremely more expenses in the future.
