Donald Trump's White House appears to be readying another of its next big climate change overhauls, and like many of the administration's plans, it will weaken or eliminate regulations on industry.

Coming this week: Trump EPA’s plan to neuter Clean Power Plan
Donald Trump's White House appears to be readying another of its next big climate change overhauls, and like many of the administration's plans, it will weaken or eliminate regulations on industry. Specifically, President Trump touted the undoing of the Clean Power Plan at a rally in Huntsville, Alabama, which foreshadowed a formal announcement... 
Continuing political turmoil and news coverage of the Trump Administration haven't stopped the president's agency heads from drastically reshaping policies on energy, the environment, and emissions. Comments are now being taken on the reopened EPA limits on vehicular carbon emissions for 2022 through 2025, although reporters had to dig to find out... 
On August 10, the U.S. Environmental Protection Agency announced it would reopen the Comment Period for the vehicle-emission standards for model years 2022 through 2025 it had finalized in January. The auto industry and its lobbyists had complained that the agency had moved too quickly, despite its issuance last summer of a voluminous Technical... 
Sometimes, when science and technology issues have economic or political consequences, incorrect or misleading information and analyses can be propagated through the media, leading both decision makers and the public astray. A piece published in April by Forbes, covering the effects of the 2022 through 2025 corporate average fuel economy... ![International Paper Company mill, 1973 [From EPA Documerica series]](http://images.hgmsites.net/tmb/international-paper-company-mill-1973-from-epa-documerica-series_100594066_t.gif)
It is abundantly clear that the Trump Administration does not believe in science. In its six months to date, it chose a climate-science denier to lead the Environmental Protection agency; rolled back two dozen regulations limiting air, water, and land pollution; and announced a U.S. withdrawal from the Paris Climate Agreement to limit carbon... 
Automakers have united behind a somewhat surprising position: reviews of corporate average fuel economy rules should not involve scrapping the current standards. The Alliance of Automobile Manufacturers, a lobbying group that represents automakers building cars in the U.S., has asked the Trump administration to solidify a deal that keeps higher... 
VW Group of North America now owns hundreds of thousands of Volkswagen and Audi TDI diesel vehicles it has bought back from owners under the terms of various diesel emission scandal settlements. Yesterday, it got some very good news: the EPA has approved a modification that will it allow it to resell the oldest and dirtiest of those vehicles... 
As rules to boost fuel economy and lower carbon emissions in vehicles around the world continue to stiffen, acronyms like EREV, CNG, and MPGe are becoming more and more common. Ever wonder what they all mean? This glossary is your chance to enter a veritable Twilight Zone of terminology--and find out, say, whether a PZEV is related to a PHEV... 
Almost one-third of the heavy trucks on U.S. roads now use the most stringent emission-control systems, which radically reduce their emissions of nitrogen oxides, soot, and other pollutants. Commercial trucks log much higher annual mileage than passenger cars, especially the semi tractors that haul long-distance freight across the country. That... 
The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their views deserve to be aired. Late last week, it... 
Sometime between March 1 and 7, a specific page vanished from the website of the U.S. Environmental Protection Agency. Amidst coverage of the removal of the word "science" from the mission statement of the EPA's Science and Technology Office, it went largely unnoticed. First posted in December 2008, and modified several times over the next eight... 
Fuel economy and emission standards have been a contentious issue in recent months as the auto industry and government officials clash over regulations and their potential benefits. Earlier this year, one of the largest pieces of evidence against more stringent fuel economy regulations came from former Ford CEO Mark Fields. Fields told President... 
During President Donald J. Trump's half-hour meeting with Pope Francis at the Vatican yesterday, the pope gave the president a copy of his 2015 encyclical calling for urgent, drastic cuts in fossil-fuel emissions. It is unclear whether the U.S. president will peruse the document. Back at home, however, his administration is continuing unabated in... 
The U.S. Justice Department may be planning to file a lawsuit against Fiat Chrysler over allegations that the engines in its light-duty diesel trucks included equipment to defeat Environmental Protection Agency emissions tests. A report from Bloomberg last week cites unnamed sources who were briefed on the forthcoming suit. The equipment in... 
Another small portion of Volkswagen's diesel scandal has been put to rest: the EPA announced its approval of modifications for 2012 through 2014 Passat TDI sedans. In total, 84,391 Volkswagen Passat TDI diesel vehicles are eligible to be modified and deemed compliant, should the existing owner choose to keep the car rather than sell it back to VW... ![Smog obscures George Washington Bridge, 1973 [From EPA Documerica series]](http://images.hgmsites.net/tmb/smog-obscures-george-washington-bridge-1973-from-epa-documerica-series_100594067_t.gif)
Much of the news out of Washington, D.C., these days has to do with the possibility of political scandal. But the wheels of government keep turning, and significant changes are happening at numerous agencies charged with missions as diverse as collecting intelligence, supporting education, and protecting the environment. Few groups are seeing... 
When a major lobbying group issues a statement replying to an academic study before that study even hits the media, you know it's major. On Monday, the Diesel Technology Forum responded to an article in Nature with a statement that supported "improved real-world testing" of diesel emissions. Those more stringent tests, the group's executive... 
Today's political climate has made for fluid motion in regulations, and corporate average fuel economy targets haven't been left out. Suppliers and automakers have already begun investing heavily into vehicles to be sold in 2022 through 2025, which will include various fuel-saving and emission-reducing technologies. However, that unsettled...
