It looks like lobbying pays off, at least in the case of EPA emission rules. According to numerous recent reports, the EPA is expected to reopen the commenting period for vehicle-emission rules it finalized in January, more than a year ahead of schedule.

It looks like lobbying pays off, at least in the case of EPA emission rules.

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... 
The average fuel economy of the new cars and light trucks sold in the U.S. is appreciably higher than it was 10 years ago. The University of Michigan Transportation Research Institute has demonstrated that in its regular reports calculating new-car average fuel economy since October 2007. But researchers Michael Sivak and Brandon Schoettle found... 
Even with aggressive promotion of battery-electric or hydrogen fuel-cell cars, hundreds of millions of internal-combustion vehicles will remain on the world's roads for decades to come. But estimates of exactly how many internal-combustion cars will be displaced by alternatives in a given period vary wildly. One alternative-fuels lobbying group... 
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... 
Because they cover significantly more mileage than the average passenger car, with much worse fuel economy, large commercial trucks are a major source of emissions. Last year, Volvo Trucks aimed to address this issue with a concept truck that demonstrated ways to improve fuel efficiency through aerodynamics and weight reduction. Volvo Trucks sells... 
The confirmation of Scott Pruitt as Environmental Protection Agency administrator was expected to rankle environmental groups. Pruitt is a climate-science denier who, in his previous position as Oklahoma attorney general, sued the agency he is now charged with many multiple times over its efforts to enforce environmental regulations. But what may... 
If you want to find a major source of transportation-related emissions, just look up. Aviation currently accounts for around 2 percent of global carbon emissions, and many analysts believe its share could triple by the middle of the century if projected growth in air travel occurs. But finding alternatives to fossil fuels has proven much more... 
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... 
Lobbyists for the world's automakers continue to ask the new presidential administration to revisit an EPA decision to finalize emissions standards through 2025. Just days after the November election, the Alliance of Automobile Manufacturers wrote President-Elect Trump to ask that he reverse the decision on emissions standards made by the... 
Estimates of electric-car market share over the coming decades vary wildly, but certain trends seem to be working in their favor. Battery prices should continue to fall, and tougher global emissions standards may put increasing pressure on automakers to build larger numbers of electric cars. But can automakers handle a sudden increase in... 
Substantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded significantly over the last decade, household... ![The White House, Washington, D.C.

Just days after the presidential election, automaker lobbyists urged Donald Trump to loosen pending emissions and fuel-economy standards. Shortly after the election, a lobbying group wrote Trump asking him to change or delay an EPA decision that kept planned emissions standards for 2022 to 2025 in place. Last week, executives of 18 automakers sent... 
In the U.S., the Volkswagen diesel scandal was a case of an automaker betraying the trust of more than half a million owners. But in the Europe, the issue of diesel emissions looms far larger yet. Diesels have represented roughly half of European car sales for decades, their good fuel economy being an asset in a region with very high fuel prices... 
Shock waves from Volkswagen's admission that it had installed "defeat device" software on its so-called clean diesels to cheat on emission tests continue to reverberate around the auto industry. The diesel-emission scandal that emerged in September 2015 has already cost VW Group more than $20 billion, and dozens of investigations around the world... 
Measuring the energy efficiency of a new vehicle is one thing, but ascertaining its overall environmental impact can be more complex. A debate still rages over the overall carbon footprint of electric cars compared to those powered by fossil fuels. But for the past 20 years, the the American Council for an Energy-Efficient Economy has tried to... 
Just days after the presidential election, an automaker lobbying group wrote Donald Trump asking him to change, delay, or dispense with an EPA decision that kept planned exhaust-emission standards through 2025. Now executives of 18 automakers have sent a second letter, asking the same thing—and echoing a statement by Ford CEO Mark Fields... 
A prominent lobbying group believes environmental remediation funds from Volkswagen diesel settlements should be spent on new "clean" diesel vehicles. The settlement for 2.0-liter TDI cars approved last year requires VW to pay $2.7 billion into a trust, managed by a third party. Volkswagen agreed to put an additional $225 million into the trust... 
What if gasoline and diesel cars and light trucks were simply eliminated altogether from the new vehicles sold in a state? Residents of one state in the U.S. may, eventually, find out. California already leads the nation in promoting zero-emission vehicles, but the Golden State may soon take that policy a step further. DON'T MISS: Will California...
