Ethanol is known as an alternative fuel, and is even renewable. But that doesn't always make it clean. The Environmental Protection Agency, after releasing proposals to water down emissions and fuel economy standards for cars, attack states' plans to bolster EV sales, and reduce emissions standards for powerplants to charge EVs, has now released a... EPA proposes more smog-contributing ethanol in summer gasoline
Ethanol is known as an alternative fuel, and is even renewable. But that doesn't always make it clean. The Environmental Protection Agency, after releasing proposals to water down emissions and fuel economy standards for cars, attack states' plans to bolster EV sales, and reduce emissions standards for powerplants to charge EVs, has now released a... 
The EPA is planning to cancel the special waiver that California has relied on since 1970 to set its own emissions standards, according to a Bloomberg report. As part of its plan to reverse a program to steadily tighten fuel economy standards that it coordinates with California and the National Highway Traffic Safety Administration, the EPA has...

After a week's delay in issuing its ruling, a German court decided that individual cities in the country may ban vehicles with diesel engines to reduce air pollution. The decision could... 
Economists call them "externalities." They're the costs of people's actions on other people or communities—though the people taking those actions don't have to pay for those costs, even as they harm others. The emissions from combusting fossil fuels to propel vehicles are clearly a prime example. DON'T MISS: A Brief History Of Smog, Which... 
California is very different from the rest of the United States. All by itself, it's the sixth largest economy in the world. One eighth of all Americans live there. It's home to Silicon Valley, as well as much of the global entertainment industry, and it produces a large proportion of the nation's fruit and vegetables. DON'T MISS: A Brief History... 
For more than 13 years, London has collected a stiff charge from motor vehicles entering the congested core of the city during weekday business hours. Known as the congestion charge, the fee of £11.50 a day, or $14.50 (£10 with automatic payment, or $12.50) is levied from 6 am to 7 pm Monday through Friday except holidays. First...
