The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.
Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. VOC emissions would have been reduced by 57 tpd.
AB 1346 would require new sales of SORE to be zero-emission by 2024 or whenever the California Air Resources Board (CARB) determines is feasible, whichever is later. Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver.
By including upstream emissions from fuels, GHG emissions from cities exceed those attributed to direct end-use by up to 24% (for Toronto). By including upstream emissions from fuels, the researchers found that GHG emissions attributable to cities exceed those from direct end use by up to 24%. Tonnes CO 2 e/capita.
The US Environmental Protection Agency (EPA) proposed standards to reduce harmful air pollution from oil and gas drilling operations. These proposed updated standards—which are being issued in response to a court order—would rely on cost-effective existing technologies to reduce emissions.
Results of new analysis conducted by German and Swiss researchers suggests that air pollution directly affects cognition and is not mediated by lung function; put another way, the two are independent risk factors for cognitive decline. 2015) “ The Roles of Lung Function and Air Pollution on Cognitive Decline: Predictor and Mediator? ”
The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.
A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. —Bishop et al. In their study, Bishop et al.
From Denver smog to jammed mountain highways, Colorado is focusing on transportation to solve congestion, pollution, and climate problems. From innovative transportation solutions to slashing emissions in the electricity […]. See more at State Climate Scorecards.
million to six research organizations to develop and to use low-cost air pollution sensor technology, while engaging communities to learn about their local air quality. While recent advances in technology have led to the development of low-cost air pollution sensors, they have not been widely tested, especially under field conditions.
Bye Aerospace’s electric Sun Flyer 2 successfully completed the first official flight test with a Siemens electric propulsion motor 8 February at Centennial Airport, south of Denver, Colo. Sun Flyer brings the full promise of electric propulsion to the market with safe, practical and reliable electric aircraft.
As a pilot, in August 2014, Aclima instrumented three Google Street View vehicles to perform a month-long system test in the Denver metro area during the DISCOVER-AQ study conducted by NASA and the US Environmental Protection Agency (EPA). Sample output from the Denver pilot. Click to enlarge.
Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality.
Vehicle tailpipes are a more important source of ammonia’s contribution to urban air pollution than is agriculture, according to a study by researchers from the US and China. Except for the Euro VI standard on heavy duty diesel vehicles, there are no vehicle emission standards to regulate NH 3 worldwide.
By taking the ICE-powered buseswhich had consumed about 240,000 gallons of diesel fuel each yearout of service at JFK, the agency said it decreased its greenhouse gas emissions by approximately 40,000 tons per annum.
Such a comprehensive approach is exemplified by California, where the Zero Emission Vehicle regulation helps to catalyze automaker marketing and model availability, complementary policy incentives, and sustained investment in charging infrastructure. Expansion of electric vehicle options is a prerequisite to market growth.
The US Environmental Protection Agency (EPA) has published the plan for the first tranche of Volkswagen’s National Zero Emission Vehicle (ZEV) Investment spending, directed at 11 cities nationwide—New York, Washington, D.C., As required by Appendix C to the 2.0-Liter Liter Partial Consent Decree entered by the US.
Conference of Mayors today unanimously endorsed a resolution encouraging the use of plug-in hybrid vehicles as an important step in reducing this country’s reliance on foreign oil and decreasing greenhouse gas emissions from vehicles. Robert Cluck of Arlington, VA, Mayor Patrick H. Become a Partner today.
US data centers are projected to consume an estimated 140 billion kilowatt-hours of electricity per year by 2020, equivalent to the annual output of about 50 power plants, emitting nearly 100 million metric tons of carbon pollution per year, according to a study by the Natural Resources Defense Council (NRDC).
The project will result in the development of approximately 184 liquid propane Autogas refueling stations in the following major metropolitan areas: Atlanta, Chicago, Houston, Denver, Sacramento, Los Angeles, Dallas, Phoenix, Indianapolis, Seattle, Orlando, San Diego, St. Total DOE award: $5,924,190.
The climate crisis is also having a severe effect on the planet, which is being battered by pollution, deforestation, and soil degradation. Ninety-nine percent of the global population breathes in air that exceeds WHO-guideline limits on pollutants, with low- and middle-income countries suffering from the highest exposures.
billion over the next 10 years in zero emission vehicle (ZEV) infrastructure, education, and access outside California to support the increased adoption of ZEV technology in the United States, representing the largest commitment of its kind to date. As required by Appendix C to the 2.0-Liter 10-year vision.
The main obstacles will be regulatory and, especially, environmental: Supersonic airliners could be hugely more polluting than their subsonic counterparts. The best-funded of this group is Denver-based Boom Technology (which also goes by the trade name Boom Supersonic). Will people soon be jetting across the Pacific in three hours?
At the time, Fiats CEO, Sergio Marchionne, was one of the loudest advocates against EVs but part of his advocacy was because he also ran one of the highest-emitting car companies, which meant it had to spend billions of dollars to make up the penalties for its noncompliance with pollution laws. Including taxes, youll have to pay a $1,297.68
By Carter Rubin, Advocate for transportation options that reduce carbon emissions and support equitable access for all. San Diego has quickly emerged as a leader when it comes to sensible updates to zoning rules that shape city neighborhoods.
EPA announces new grant program to fund zero-emission heavy-duty vehicles, infrastructure, and workforce development to tackle climate change, reduce air pollution, and advance environmental justice DENVER — Yesterday, April 24, the U.S.
The US Environmental Protection Agency (EPA) released the already widely-discussed (albeit without much detail) “Clean Power Plan” proposal, which mandates a national average 30% cut in greenhouse gas emissions from existing power plants from 2005 levels by 2030. EPA is only proposing goals for states with fossil fuel-fired power plants.
