Widespread implementation is achievable with existing technology but would require significant strategic investment and institutional arrangements, the study found. Widespread implementation is achievable with existing technology but would require significant strategic investment and institutional arrangements, the study found.
Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and Waste management. Pellet stoves and boilers, using fuel made from recycled wood waste or.
A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C Source: Shindell et al.

million in new grants to study the use and impacts of escaped nitrogen from agricultural production. Wastes from cattle, chickens and other livestock include nitrogen. The new studies should improve data-collection methods, said Agricultural Sustainability Institute researcher Johan Six, a professor in the Department of Plant Sciences.
A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) The study, lead by Professor Barbara Finlayson-Pitts shows, however, that the uptake of oxides of nitrogen and HCl on surfaces rather can be an intermediate step on the way to generating more reactive gases. Raff et al.
On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. A paper on the study appears in the ACS journal Environmental Science & Technology.
A study by researchers at Lund University in Sweden found that Swedish biofuels produce between 65 and 148% less greenhouse gas emissions than gasoline and diesel, even when direct and indirect land use changes are taken into account. Direct and indirect land use changes were also studied. (A A hat-tip to John!).
The study is published in the ACS journal Environmental Science & Technology. In particular, silicon nanowires (SiNW) are widely studied as a promising anode material for high-capacity LIBs due to its low cost of fabrication and volume production potential. The LCA was based on the average US driving and electricity supply conditions.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. An important analytical issue that needs to be addressed, the report notes, is the lack of lifecycle assessment studies focusing on a wider set of environmental impact indicators than greenhouse gas emissions.
The first is the Vehicle Technologies Office (VTO), which aims to advance combustion engine technology and simultaneously reduce criteria emissions, such as carbon monoxide, nitrogen oxides and ozone. —Doug Longman, section manager of engine combustion research within Argonne’s Energy Systems division.
Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.
HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
These technologies include, but are not limited to, advanced aftertreatment and waste heat recovery; lean-burn plus lean-NO x emissions traps; integration of zero-emission miles technologies; further refinements in reducing friction and parasitic energy losses; and widespread utilization of renewable and natural gas and hydrogen blends.
That the reduction has not materialized—and that global emissions have instead risen—is a puzzle, and may have implications for the Montreal Protocol, the international treaty that was designed to protect the stratospheric ozone layer. However, it looks like there is still work to do. —Dr Stanley. Resources. Stanley, D.
As a BYD investor, I'm upset to see them waste so much money on dead technologies like PHEVs/EREVs. Swapping out CO2 for other toxins like ozone and nitrogen oxides is not a solution. As the economies of scale disappear for ICE, so too will they disappear for hybrids that depend on the existence of ICE.

Dow Chemical Company will partner with SNL to reduce the thermal conductivity of insulating foam polyurethane products while using less polymer in its products in a project titled “Predictive Modeling of Polyurethane Foam Processes to Optimize Thermal Performance and Reduce Waste”.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. cents to 10 cents per kilowatt-hour, based on previous modeling studies. cents per kwh.
Methyl halides are naturally produced by a number of organisms; the enzyme responsible for this production—methyl halide transferase (MHT)—has been studied in the context of the environmental production of methyl halides, which contribute to ozone depletion. cerevisiae for metabolism of toxic waste products.
The study was published 8 June in the open access IOP journal Environmental Research Letters. Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data).
Accordingly, there have been a number of recent studies working to assess the impact of non-exhaust emissions from EVs and suggesting a regulatory or policy response (e.g., A 2014 study by Weinbruch et al. Compared to earlier studies, Weinbruch et al. A new Rotterdam-specific study by a pan-European team (Tobollik et al.
In general, biofuels made from organic waste are environmentally more benign than those from energy crops. Other observations included: Most studies only include energy consumption (sometimes only non-renewable energy, sometimes total energy) and CO 2 emissions. However very few studies include water use impacts.
Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. These small studies would still yield significant information on the impacts of brightening.
California’s and, potentially, EPA’s move toward further heavy-duty NO x reductions to meet National Ambient Air Quality Standards for ozone will be critical. Studies, some of which are under way that contribute to this objective, should strive to answer questions such as what fuel properties (e.g.,
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, Nuclear waste is a problem much harder to solve than CO2, and dams have quite an impact in the environment.
