It can be argued that the current presidential administration appears to lack interest in the traditional mission of the Environmental Protection Agency. As a candidate, Donald Trump advocated wholesale repeal of environmental regulations and increased production of fossil fuels. He has also called climate science a "hoax" created by China to hurt... 
As a presidential candidate, Donald Trump vowed to "bring back coal" as part of a larger program to encourage greater production of fossil fuels. But the coal industry believes it needs more than an ostensibly friendly administration in Washington to survive. With coal production down and electric utilities continuing to switch to lower-cost... 
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... 
During negotiations for the Paris Climate Treaty signed last fall, a major concern among critics was whether the carbon emissions of China's sprawling and inefficient energy sector could be reined in. With China, the U.S., and dozens of other countries signing the agreement, the world's most populous country committed itself to decarbonizing its... 
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... 
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. DON'T MISS: Why Africa gets filthiest diesel fuel: little... 
Even before the Volkswagen diesel scandal, diesel passenger cars were never popular in the U.S. But in other parts of the world—especially Europe—diesels have been the de facto choice of many buyers for decades. Increasing concern over air pollution and the VW scandal are beginning to change that, though. DON'T MISS: Paris weekday ban... 
The Volkswagen diesel scandal convinced European regulators to switch from laboratory emissions testing to tests that involve actual, on-road driving. This could prevent automakers from deploying "defeat device" software like the kind used by VW on laboratory tests, as well as produce results that more closely align with what consumers can expect...
