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... 
China is known for having some of the most polluted air in the world. But officials in one Chinese city found a way to at least make that air appear cleaner, for awhile. Like many Chinese cities, Xi'an, the provincial capital of Shaanxi, in the northern part of the country, has air-monitoring equipment. DON'T MISS: Coal in China: huge problem for... 
Over the past few years, China has made impressive strides in renewable-energy investment. The promotion of renewable energy will only become more important as China works to meet its commitments under the recently-ratified Paris climate agreement. But the country's reliance on coal for electricity generation still poses a huge problem for these... 
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... 
It's entirely obvious that internal-combustion cars pose a threat not only to the environment, but also to human health. Exhaust from gasoline and diesel cars contributes to air pollution that can lead to deleterious health effects after long exposure. Now a new study from the American Lung Association in California aims to quantify the health... 
Last December, representatives form 195 countries met in Paris to negotiate an agreement to address climate change on a global scale. Almost a year later, enough countries have now formally ratified that agreement in order that it can officially take effect. The tipping point was reached when India and the 28 members of the European Union ratified... 
While automakers work to meet stricter carbon-emissions standards, another sector of the U.S. economy has already made notable progress in reducing ts emissions. Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)... 
Cars and trucks aren't the only source of transportation-related carbon emissions. The massive ships that ply the world's oceans are major sources of pollution as well, but generally receive less attention from regulators. But one cruise line is now taking steps to reduce the environmental impact of its fleet. DON'T MISS: Cruise ships start to... 
All countries have to deal with emissions from diesel vehicles, but African nations have it worst than most. They often have few emissions regulations, something Swiss trading firms take advantage of by importing fuel that's too dirty for sale in other regions. These firms often serve as both producer and distributor for fuels in Africa, according...
