This is the first such crackdown in over 30 years

More than 80,000 chemicals are used or produced in the U.S., and the Environmental Protection Agency (EPA) has placed restrictions or bans on just five. But the agency signaled its intent at the end of last year to possibly add restrictions to four chemicals that are widely used in making products such as toys, household items and medical equipment, according to Scientific American.

EPA Proposes Tighter Restrictions On Smog-Causing Emissions

The changes could cost industry $90 billion, and substantially improve Americans' health

In a move to curb smog, the Environmental Protection Agency (EPA) has proposed the tightest regulations ever on ground-ozone-causing emissions. The new standards would replace 2008 ozone regulations implemented by the Bush administration that allowed so much smog emission that environmental advocates took the EPA to court, arguing that the weak emissions regulation didn't actually protect people's health.

GM Claims Chevy Volt Will Get 230 MPG--But How?

General Motors CEO Fritz Henderson says the EPA will certify the Chevrolet Volt with triple-digit mileage. How'd they come up with that?

[Update: The EPA issued a statement to the folks at Edmunds stepping back from GM's mileage claim: "The EPA has not tested a Chevy Volt and therefore cannot confirm the fuel economy values claimed by GM. EPA does applaud GM's commitment to designing and building the car of the future - an American-made car that will save families money, significantly reduce our dependence on foreign oil and create good-paying American jobs."]

General Motors calls the Chevrolet Volt an extended-range electric vehicle. That's because the only motive force comes from the electric motor; the gas engine only charges the batteries. In a press conference earlier today, GM's CEO Fritz Henderson said the Volt will have a city mileage figure of 230 miles per gallon--almost five times more efficient than a Prius.
