You might want to think twice before placing an order on a charbroiled burger. According to a study by UC Riverside (UCR), commercial charbroilers can emit twice the amount of pollution as diesel trucks. One researcher describes the devastating "Fast-food carbon footprint" as such:
“..an 18-wheeler diesel-engine truck would have to drive
143 miles on the freeway to put out the same mass of particles as a
single charbroiled hamburger patty,"
The reason for the concern is there are simply not enough regulations on restaurant emissions, despite the fact that commercial cooking equipment generates grease, smoke, heat, water, vapor, and combustion products.
