Anyone that has ever climbed into a car on a sunny day is familiar with the greenhouse effect. The interior of the car is typically much hotter than the ambient temperatures outside, sometimes as much 20-30 degrees F more. As a result, drivers (unless they have the new 2010 Prius with solar roof option) often crank up the air conditioning to make the interior bearable, a habit that puts more load on the engine and increases fuel consumption. The California Air Resources Board wants to address this situation with a new regulation. Starting in 2012, new vehicles will have to incorporate glass that reflects 33 percent more infra-red radiation away from the car and keeps the interior cooler. It’s estimated that the changes will result in a 700,000 ton reduction in greenhouse gas emissions in California annually by 2020. The standard, which will be implemented in two steps in 2012 and 2016, is expected to add $70 and $250 respectively to the cost of the car.
