Control

California got caught cooking the books in order to strengthen their air pollution bureaucracy.

The pollution estimate in question was too high - by 340 percent, according to the California Air Resources Board, the state agency charged with researching and adopting air quality standards. The estimate was a key part in the creation of a regulation adopted by the Air Resources Board in 2007, a rule that forces businesses to cut diesel emissions by replacing or making costly upgrades to heavy-duty, diesel-fueled off-road vehicles used in construction and other industries.

If the overstatement has any basis in fact, construction must be about 1/3.4 or 29% of what it was projected to be.

I suppose if you choke an economy sufficiently, fuel usage will go down, as no one will be going to work any more, and the air will magically get cleaner. Just like in Zimbabwe.
