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 ventilation air from coal mines. of oil and natural gas. for 2030 and beyond. Source: UNEP.
Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.
Researchers at Japan’s Central Research Institute of Electric Power Industry (CRIEPI), in a project funded by the New Energy and Industrial Technology Development Organization (NEDO), have successfully developed a method to extract oil from algae using liquefied dimethyl ether (DME) at room temperature in high yield.
Poor women and children pay a heavy price from indoor air pollution since they spend more time at home breathing in smoke and soot from leaky coal and wood cook stoves. million deaths in 2012 in households cooking over coal, wood and biomass stoves. Ozone is a major factor in asthma morbidity and mortality. g/m 3 8-hour mean.
1,000 to 21,000) deaths due to changes in ozone concentrations. 900 to 11,000) ozone-related early deaths per year. 300 to 4,000) ozone-related premature mortalities per year. 2000 (90% CI: 0–4,000) early deaths from ozone, according to the study. 53,000 (90% CI: 24,000–95,000) PM 2.5 related premature deaths and ?5,000
Photochemical Ozone Creation Potential (kg Ethene equivalent). Quantifies the production of pollutant ozone (? to ozone layer), the results of the reaction of sunlight on NO x and volatile organic compounds. water, and non-renewable energies (crude oil, coal.) Quantifies the quantity of energy (crude oil, coal.)
coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Summer fine particulate matter (PM 2.5 ) increases on average and largest in areas with increased coal-fired power generation demands. Schnell et al.
Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Hydroprocessing of renewable oils to create a hydroprocessed renewable jet (HRJ) fuel.
It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. The AGGI includes methane and nitrous oxide, for example, greenhouse gases that are emitted by human activities and also have natural sources and sinks.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. not reformulated) gasoline; and (4) crude oil production is 100% conventional crude (most oil sands production occurs outside of our spatial modeling domain—i.e., the contiguous US).
Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.
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). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
One key issue that the Waxman-Markey discussion draft does not address is how to allocate the tradable emission allowances that restrict the amount of greenhouse gas emissions from electric utilities, oil companies, and other sources. The Chairmen say this issue will be addressed through discussions among Committee members.
