Interesting, but not even half as mind blowing as the work of genius and inventor Donald Stedman, who was a chemist at the University of Denver. More than 30 years ago, Stedman came up with a machine that could instantly measure and analyse the emissions of cars driving past, used infrared light.
He earned a bachelors degree in electrical engineering from Purdue University , in West Lafayette, Ind. He earned two bachelors degrees, one in computer science in 1976 and the other in electrical engineering in 1978, both from the University of Sydney. He later returned to the University of Massachusetts and in 1996 received a Ph.D.
The global economic recession of 2008—which severely depressed light-duty vehicle sales—resulted in an increase in the age of the light-duty vehicle fleet in the US that likely slowed the rate of decrease of fleet average emissions, according to a study by Gary Bishop and Donald Stedman at the University of Denver.
A research team led by The University of Texas at Austin, and including engineering and environmental testing firms URS and Aerodyne Research, is conducting a major field study to measure methane emissions from natural gas production, about which little empirical data exist.
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.
To complement its work on real-world emissions in Europe, TRUE has compiled remote sensing data from the states of Colorado and Virginia and the University of Denver to investigate the emissions of US light-duty vehicles. By 2018, the percentage of the fleet responsible for 50% of total NO emissions had decreased to 11%.
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.
earlier post ) found that such biodiesel reduces greenhouse gases (GHG) emissions by 90% compared to petroleum diesel in the US. A life cycle assessment (LCA) of biodiesel produced from castor bean varieties being developed by Israel-based Evogene Ltd.
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.
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.
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.
Georgia has a tax credit worth up to $5,000 for zero-emissions vehicles. Louis, where the reasons for growth in this “New Wave” market include enthusiastic dealer engagement that results in increased community education and awareness, corporate and university outreach and midwestern pragmatism that appreciates the value equation of an EV.

A review of 20 years of technical literature on natural gas (NG) emissions in the United States and Canada comprising more than 200 papers has concluded that official inventories consistently underestimate actual CH 4 emissions due to leakage from the natural gas system. number of devices). number of devices).
PRIME Coalition, a 501(c)(3) public charity funding tech start-ups that fight climate change, closed three new investments: Opus 12 in Berkeley, CA; Mallinda in Denver, CO; and Lilac Solutions in Oakland, CA. Founder/CEO Dave Snydacker developed Lilac's technology at Northwestern University.
The grants, which are funded through the EPA’s Science to Achieve Results ( STAR ) program, are being awarded to the following: Carnegie Mellon University will research the accuracy of air pollution sensors and the usefulness of the sensor data. to design and conduct air quality monitoring studies.
A team at the University of Denver has measured the emissions from two in-use California heavy-duty truck fleets—at the Port of Los Angeles and the Cottonwood weigh station in Northern California—using the On-Road Heavy-Duty Measurement System in 2013, 2015 and 2017. Credit: ACS, Haugen and Bishop (2018).
Instead, the research team found that ammonia emissions from cities are much larger than recognized, occur at the very times when unhealthy particulate matter is at its worst, and when agricultural emissions are at daily or seasonal lows. Vehicle NH 3 emissions depend on road grade, driving mode, and vehicle age.
USGS scientists, with partners at the Universities of Arizona, Washington, Wyoming, and Western Ontario, led the study that evaluated the recent declines using snowpack reconstructions from 66 tree-ring chronologies, looking back 500 to more than 1,000 years.
These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality. If emissions of that molecule are reduced, then ozone formation will be reduced—critical information for air quality managers.
We are beginning to get a sense of regional variation in methane emissions from natural gas production. CIRES is a partnership of NOAA and the University of Colorado Boulder. In the new study, the researchers also reported their findings by region: Methane emissions in the Marcellus region of northeastern Pennsylvania were about 16.5
million in grant selections through the Low- or No-Emission (Low-No) Grant program, which funds the deployment of transit buses and infrastructure that use advanced propulsion technologies. Fiscal Year 2019 Low or No-Emission (Low-No) Bus Program Projects. Alabama A&M University. Project Sponsor. Project Description.
To explore how e-scooters are affecting road safety, IIHS researchers interviewed more than 100 e-scooter riders whose injuries brought them to the emergency room at George Washington University Hospital in Washington, DC, between March and November 2019. Shared e-scooters logged 86 million trips in the US in 2019.
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.
Fleets include transportation authorities, cities, school districts, the University of Michigan, FedEx, and Meijer. The fleets include two utility fleets, five cities and towns, three counties, ten private companies, two state fleets, ten school districts, and two universities. Total DOE award: $14,970,144. Total DOE award: $5,924,190.
Just what effect could widespread use of plug-in hybrid electric vehicles have on emission levels? Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory believe they have the answer.
Such a vehicle could reduce gasoline consumption for the average American by 50 percent to 70 percent and reduce automobile emissions well in excess of emissions that might result from the additional use of power plants. EV world NATIONAL COALITION LAUNCHES CAMPAIGN TO URGE AUTOMAKERS TO PRODUCE PLUG-IN HYBRID VEHICLES WASHINGTON, D.C.—January
A new study by a team from the University of Pennsylvania and MIT suggests it will be easier for cities to reduce CO 2 emissions coming from residential energy use rather than from local transportation. The CPP is intended to reduce greenhouse gas emissions from power plants.
