California began regulating vehicle emissions within its boundaries before the Environmental Protection Agency was even a gleam in President Richard Nixon's eye. Since that agency was founded in 1971 with an executive order by Nixon, the state has retained the right to set its own—more stringent—emission rules. Now, under President... Will Trump EPA target CA electric-car, emissions rules? Not yet, maybe; here’s why
California began regulating vehicle emissions within its boundaries before the Environmental Protection Agency was even a gleam in President Richard Nixon's eye. Since that agency was founded in 1971 with an executive order by Nixon, the state has retained the right to set its own—more stringent—emission rules. Now, under President... 
Anniversaries often provide an opportunity to reflect on important past events, review what has happened since, and reflect upon the future. April 2 of this year marks the 10th anniversary of the Supreme Court ruling in Massachusetts vs EPA in which the EPA was forced to regulate carbon emissions. The passing of this anniversary was marked by an... ![Natural gas flaring from oil well [licensed under Creative Commons from Flickr user Sirdle]](http://images.hgmsites.net/tmb/natural-gas-being-flared-from-oil-well-licensed-under-creative-commons-from-flickr-user-sirdle_100443858_t.gif)
While much of the nation's capital is preoccupied with the unpredictable Trump administration and its possible ties to Russia, the fate of the Environmental Protection Agency generates less news coverage. That's not to say there hasn't been news. Administrator Scott Pruitt is proceeding swiftly with a radical plan to restructure—critics... 
Barbie never said "Math is hard!" The talking doll did, notoriously, say "Math class is tough!" in 1989, sparking a media firestorm over gender roles in childrens' toys and then a voluntary recall by Mattel for offended parents. Reworded, however, the point remains accurate: many people don't understand math. DON'T MISS: Costs to meet fuel-economy... 
It has become increasingly more evident that carmakers must take aggressive steps to ensure that diesel cars and light trucks meet current environmental regulations. Tests done by Emissions Analytics found that the majority of new diesel-powered cars sold in Europe do not meet the Euro 6 emission standards for nitrogen oxides (NOx) in real-world... 
Advocates have long suggested that electric vehicles will begin to take over daily driving duties, slowly but surely, from the internal-combustion engine. Now, even oil companies are starting to acknowledge that there may be reality in that dream of the future. France's Total SA, one of the world's largest oil producers, released its future... 
The current EPA administrator, Scott Pruitt, does not accept the scientific consensus on human contribution to climate change, though he has given some contradictory statements on that matter. His views correspond closely to those of his boss, President Donald Trump, who notoriously compared the science to bovine excrement in a tweet and called... ![Donald J.

As the Trump Administration nears its 100th day, it seems fair to say that it is still emitting mixed messages on multiple issues, from foreign policy to climate change. On that latter, it's important to reiterate that the president and many of his appointed agency and department heads deny the science of climate change. On the campaign trail, the... 
The challenges of building fueling infrastructure for passenger cars powered by hydrogen fuel cells are well known by now. Toyota, Honda, and Hyundai now lease low volumes of fuel-cell vehicles in selected areas of California where a few dozen hydrogen fueling stations are now up and running. The challenges for fueling may be less daunting for...
