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.
Pechman for the Western District of Washington has ruled that the Washington Department of Ecology, Northwest Clean Air Agency, and Puget Sound Clean Air Agency must regulate greenhouse gas emissions (GHGs) from the five oil refineries operating in Washington State. matter, sulfur dioxide, ozone, nitrogen dioxide, carbon monoxide, and lead.
The basic properties of thermoplastic polyurethanes include high scratch and abrasion resistance, high tensile strength, very good cushioning, high flexibility at cold temperatures, and excellent resistance to oil, grease, oxygen and ozone.
Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. A key piece of the SLCP Strategy is a new regulation aimed at reducing methane leaks from oil and gas operations. emissions by more than 20%. emissions by more than 20%.
When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study.

eutrophication; ET = ecological toxicity; FEC = fossil energy consumption; WU = water use; LO = land occupation; “The rest” includes acidification; smog formation; ozone layer depletion; and human health effects. For gasoline, the study reflects the US context in which crude oil is to a large extent imported and refined domestically.
More findings from the CalNex research on a variety of subjects, from the formation of ozone to the interactions of particles and clouds, are being presented at a four-day workshop May 16 through 19 in Sacramento, California.
It does not include emissions from petroleum refineries and oil production. The transportation sector represents tailpipe emissions from on-road vehicles and direct emissions from other off-road mobile sources. Source: ARB. MMTCO 2 e (6%) from 2013 to 2017.
Engine and drive system hoses require a particularly high level of oil and heat resistance. Since epichlorohydrin offers exceptional oil resistance, heat resistance, heat aging resistance, ozone resistance, and gas permeability, it is currently commonly used as a key compound in the production of rubber for components such as hoses.
The team, from the Desert Research Institute, University of Colorado Boulder and NOAA, and Stanford University, began by defining a consistent vocabulary, first by jettisoning the popular umbrella label of “fracking” applied to unconventional oil and natural gas development.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. The highest variations are observed for biodiesel from palm oil and soya. Rapeseed biodiesel as an example of the varied environmental impacts of a particular biofuel. Source: “Assessing Biofuels”.
The two vehicles, working together to gather upwind and downwind readings of sources, will monitor for methane, nitrous oxide, carbon dioxide, halocarbons, sulfur hexafluoride, carbon monoxide, ozone and particulate elemental carbon; as well as particulate matter size and distribution.
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).
The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone.
Testing is due to be complete next year, prompting the auto, oil and outdoor power equipment industries to urge the Environmental Protection Agency (EPA) to delay action on its proposal to allow higher levels of ethanol in gasoline until that testing is done. Earlier post.) Emissions inventory and air quality modeling. (A-67 A-67 / A-73).
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. of the estimated total.
The best cost estimates of cellulosic biofuel are not economical compared with fossil fuels when crude oil’s price is $111 per barrel. However, air-quality modeling suggests that production and use of ethanol to displace gasoline is likely to increase air pollutants such as particulate matter, ozone, and sulfur oxides.
The major sources of methane in California are livestock (~30% of the state’s methane emissions), followed by landfills and oil and gas production. This aligns with the federal government’s current goal of reducing methane emissions from oil and gas operations by 40–45% below 2012 levels by 2025.
