When it comes to regulations governing the auto industry, the Obama administration does not plan to go gentle into that good night. The outgoing administration has pushed through a number of new regulations, some related to fuel efficiency, before President-elect Donald Trump takes office next month. The move is likely a hedge against the incoming... 
It's well known by now that the European Union testing protocol for fuel economy is much less rigorous than the U.S. Environmental Protection Agency (EPA) standards. Both protocols are based around laboratory testing rather than real-world evaluation, but EU figures have gained a reputation for being much more optimistic than what drivers can... 
Over the past few years, the cost of electricity generation from renewable-energy sources has decreased dramatically. So much so, that renewable energy may have just hit an important milestone, according to one study. In the U.S., wind and solar power are now cheaper sources of electricity than natural gas—even without subsidies. DON'T MISS... 
Ambitious emissions-reduction goals are important, because they allow policymakers to coordinate and focus efforts on a defined target. But the problem with setting lofty goals is that, eventually, they must be met. The German government is now finding out how difficult that can be.

Exhaust emissions from gasoline and diesel cars get a lot of attention from policymakers attempting to combat climate change. But another very large source of carbon emissions has nothing to do with transportation. Emissions of methane have increased dramatically over the past few years, with livestock raised for human food as the largest source... 
Global efforts to reduce greenhouse-gas emissions may be starting to pay off, suggests a recent study. Last month, scientists released an assessment that suggests global carbon emissions did not increase significantly in 2016. That makes this the third year in a row that carbon emissions have remained flat. DON'T MISS: Renewable energy growth... 
When it comes to green cars, California leads the nation—and has done so for decades. California residents buy more hybrids and electric cars than those of any other state, and it is also the only state with fueling infrastructure to support the sale of hydrogen fuel-cell vehicles. Consumer enthusiasm is underpinned by strict regulations... 
It's been 15 months since news broke that VW Group had used "defeat device" software in its diesel cars and SUVs that let them emit far more than permitted levels of nitrogen oxides in real-world use. Even now, however, the Volkswagen diesel scandal continues to grow new tentacles as investigators uncover additional apparent instances of... 
The Volkswagen diesel scandal has led to numerous lawsuits against the German automaker in multiple countries. But now regulatory agencies in European countries have become caught up in the legal fallout from VW's emissions cheating. The European Union began legal action Thursday against Germany, the U.K., and five other nations. DON'T MISS: Every... 
African nations have a very specific problem when it comes to dealing with emissions from diesel vehicles. Because of lax emissions standards, traders import fuel to these countries that is too dirty for sale elsewhere. But now a handful of African nations are taking a stand against this.
