In an effort to address growing traffic congestion and air quality concerns, UPS and Seattle Mayor Jenny Durkan announced the deployment of an innovative downtown delivery pilot project using pedal-assist cargo eBikes and customized, modular trailers.
A new report by the Union of Concerned Scientists (UCS) finds that the rising use of ride-hailing services is increasing carbon emissions, with ride-hailing trips producing nearly 70% greater emissions compared to the trips they are replacing. —Jeremy Martin, senior scientist and director of fuel policy at UCS.
Built by Seattle-based Foss Maritime, it began working the ports of Los Angeles and Long Beach in January 2009. criteria pollutants—nitrogen oxide, carbon monoxide, particulate matter—and the greenhouse gas carbon dioxide were measured based on the ISO 8178 protocols. Each array stores 170.1 Emissions of.
When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
The grants awarded today will help six ports improve air quality and reduce carbon emissions, by providing $4.2 million in Diesel Emissions Reduction Act (DERA) grants to retrofit, replace, or repower diesel engines resulting in immediate emissions reductions in harmful pollution.
Scientists from the US, Norway, Russia, Germany, Italy and China are participating in a study examining the potential role of black carbon, or soot, on the rapidly changing Arctic climate. Black carbon is contributing to this warming. Carbon is dark in color and absorbs solar radiation, much like wearing a black shirt on a sunny day.
Additionally, one of the urea SCR vehicles was operated over a total distance of ~4,000 km (~2,485 miles) between Los Angeles, CA and Seattle, WA to investigate emissions reduction characteristics over extended highway driving conditions. The researchers acquired two cars from a rental agency and one from a private owner.
For example, recent on-road emission measurements in California and other locations have shown that the 99 th percentile is responsible for more than a third of the carbon monoxide (CO) and hydrocarbon (HC) emissions and more than 15% of the nitric oxide (NO) emissions on a fuel-specific basis, and these imbalances continue to grow each year.
Topic Area 1: Computational Energy Sciences: Multiphase Flow Research Multiphase flow is prevalent in fossil-fuel processes, appearing in processes such as coal gasifiers, reactors used for sorbent-based carbon dioxide (CO 2) capture, and emerging technologies that help with efficient CO 2 separation. University of Washington, Seattle, Wash.
There are two public hearings scheduled for this proposed finding: 18 May at the EPA Potomac Yard Conference Center, Arlington, VA; and 21 May at the Bell Harbor International Conference Center in Seattle, WA. The scientific analysis also confirms that climate change impacts human health in several ways.
In the Lower GHG Scenario, further reductions in carbon emissions result from adoption of policies that apply an increasing price on carbon emissions, resulting in faster deployment of low-emission generation technologies. levels throughout the United States. Environmental Assessment of a Full Electric Transportation Portfolio.
H ere is a guest editorial from a plug in partner city that appeared in the Seattle Post Intelligencer. Plug-ins could make a big dent in global warming pollution. Plug-ins could be virtually carbon free if Washington develops its significant undeveloped renewable power and energy efficiency resources.
According to the findings, the six key greenhouse gases - carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydroflurocarbons (HFCs), perflurocarbons (PFCs) and sulphur hexafluoride (SF6) - threaten the welfare of both current and future generations.
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.
Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.
We also think that with more people realizing that global warming is our greatest challenge, and that evolving the transportation sector to zero-carbon via cellulosic ethanol plug-in hybrids plus electricity from renewable sources may be our best strategy, the discussions about payback are a narrow answer to big questions.
The objections they raised for years -- "no one is interested, no one would plug in, the technology is too complex, the benefits are minimal, its just shifting the pollution from the tailpipe to the smokestack, theres no demand for these cars" -- still show up occasionally, but are by and large history. We need to know, is it viable?
The GridWise smart-grid trial in the Seattle area in 2007 found that consumers lowered their energy use by 10 percent and utilities were able to shave their peak demand by 15 percent. In the telecom industry, people quickly adjusted to call at night to get cheaper rates. Subscribe via RSS Click this link to view as XML.
Earlier this year, the state introduced a new carbon-pricing program (part of the Climate Commitment Act, and Clean Fuel Standard) that fines businesses for any greenhouse gas they emit. According to The Seattle Times , the first two quarterly auctions of Washington’s emission allowances hauled in more than $850 million.
