Another Berkeley 'First': Banning Natural Gas Lines in New Buildings
On Tuesday night, the City Council of Berkeley, Calif., unanimously voted to ban natural gas infrastructure from new buildings starting next year, the first city in the U.S. to pass such an ordinance. Fifty cities in the state could be next.
Summertime Ethanol Restriction Lifted to Help Corn Farmers—But at What Cost?
President Trump made good on his promise last October to lift the E15 ban in time for the summer driving season. Not mentioned by the Des Moines Register are the downsides to allowing the higher ethanol blend to be sold during the summer, e.g., smog.
When Academic Research Goes Bad
A 'misconduct investigation' decided that an industry-funded study, used by the EPA as the basis to roll back a regulation limiting the number of old engines that could be used in new truck chassis (i.e., "glider trucks"), was inaccurate.
More Diesel Driving Bans Coming to German Cities
Germany's automotive industry and Chancellor Angela Merkel are increasingly worried about the economic effects of court-sanctioned diesel driving bans to improve air quality, as enacted in Hamburg last May. Four more cities are likely to enact bans.
Making Older Coal Power Plants More Efficient Without Making Them Cleaner
At the center of the EPA's newly proposed Affordable Clean Energy rule is doing away with a permitting process known as New Source Review that requires coal power plants to add scrubbers and other expensive pollution control equipment when upgraded.
A Departing Blow to Clean Air on Pruitt's Final Day
Friday may have been disgraced EPA Administrator Scott Pruitt's last day in office of the agency in charge of protecting the nation's environment, but he still managed to roll back a regulation to create lasting air pollution far greater than VW did.
Another EPA Rollback, Tailor-Made for Gov. Walker and Southeast Wisconsin
Politics and economics win over public health in Racine County as the EPA exempted the area around the Foxconn's massive facility from meeting stricter ozone pollution standards, saving the company from investing in smog-reducing equipment.
German Cities to Breathe Easier After Court Ruling on Diesel Car Bans
Unlike banning sales of new internal combustion vehicles at a future date, the German court ruling applies to the operation of older, diesel-powered cars in the country's most polluted cities. It's up to the cities, though, to enact the bans.
Southern California Air Quality Paradox: Air Quality Worsens While Emissions Drop
Ozone pollution is worsening in five counties in Southern California, and the Air Quality Management District doesn't know why.
Electrifying California: Volkswagen Settlement Approved
The biggest obstacle to the adoption of electric vehicles in California, a shortage of charging infrastructure, just became a lot more manageable thanks to $200 million from Volkswagen stemming the from the dieselgate settlement.
Inadequate Diesel Vehicle Testing Results in 38,000 Global Fatalities Annually
While the study stems from research that found Volkswagen diesel cars had used 'defeat devices' to pass emissions tests, the new study points to inadequacies in the tests themselves, resulting in 50 percent higher pollution than testing permits.
The Environmental Trade-Off for Raising California's Fuel Taxes
Come November 1, gasoline and diesel taxes will increase by 12 and 20 cents per gallon, respectively, in California, providing badly needed revenue to repair roads, bridges, and improve transit, but truck pollution loophole will still foul the air.
Air Quality and Environmental Justice Lead to Push for Zero-Emission Locomotives
The California Air Resources Board has petitioned the U.S. EPA to adopt more stringent emissions standards for locomotives in order to improve air quality at rail yards, many of which are located adjacent to disadvantaged communities.
Cleanest Diesel Locomotives to Join Southern California Commuter Rail Fleet
Forty so-called Tier 4 locomotives, a U.S. Environmental Protection Agency designation requiring a dramatic reduction in particulate and nitrogen oxide emissions, will be joining Metrolink's fleet covering 512 track miles in six counties.
EPA Rejects Southern California Plan to Reduce Fine Particulate Pollution
The South Coast Air Quality Management District is in the news again, this time for going too easy on the region's big polluters—just what staff had warned would happen before the board fired its well-respected executive director.
Volkswagen Submits Another Recall Plan for Diesel Cars
Volkswagen has already submitted its recall plan for its 2-liter diesel engines—it was rejected by both the EPA and California Air Resources Board. It also needed to submit a recall plan for 3-liter diesel engines to CARB by Feb. 2, which it did.
New Delhi Restricts Diesel Cars; Beijing Issues Second Red Alert
It took an act of the Supreme Court for India to address the incredibly unhealthy levels of particulate matter in New Delhi. New rules are aimed at diesel cars, SUVs, and taxis. In Beijing, pollution triggered a red alert for only the second time.
