New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.
Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease. —Guy Brasseur.
The US Environmental Protection Agency (EPA) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposal also includes incentives to spur the oil and gas industry to minimize leaks.
The market for water treatment for hydraulic fracturing (“fracking”) to produce previously inaccessible shale gas will grow nine-fold to $9 billion in 2020, according to a new report from Lux Research. EcoSphere combines ozone, cavitation, and electrochemistry, and the $9 million company leads in the “Dominant” quadrant.
California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.
From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. from 2005 to 2020. to 7,416 Tg CO 2 Eq., to 1,853 Tg CO 2 Eq. 5,813 Tg CO 2 Eq. 605 Tg CO 2 Eq. 6 Tg CO 2 Eq.
Deterioration of the ozone layer [kg CFC-11-eq.]. The program guides the interested layperson through a selection of parameters: which type of engine should be used, gasoline-burning or diesel, for example, or one powered by natural gas, a fuel cell, or a battery. 2020) Submitted to Renewable and Sustainable Energy Reviews.
In addition, the program funds projects that assist in fulfilling Governor Brown’s Zero Emission Vehicles (ZEV) Action Plan, with a target of installing enough infrastructure to support 1 million ZEVs by 2020, and a 2025 target of having 1.5 12 million for natural gas vehicle incentives. million ZEVs on the state’s roads.
The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. 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.
Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. This gas has very few industrial applications. —Dr Stanley. Resources. Stanley, D. Krummel, D.
Chlorofluorocarbons (CFCs)—commonly used in refrigerators and air conditioners—play a role in creating a hole in the ozone layer over Antarctica. 2 in 2020, before declining by approximately 26% by 2050, despite continued growth of fully fluorinated greenhouse gas emissions. —Ronald Prinn. Rigby, M.,
The California Air Resources Board on Thursday adopted the final greenhouse gas (GHG) emissions cap-and-trade regulation. Compliance obligations for greenhouse gas emissions begins 1 January 2013. the second, starting in 2015, brings in distributors of transportation fuels, natural gas and other fuels. Earlier post.)
B) Temperature dependence of total gas-phase emissions from asphalt, ranging from in-use (40 °C to 60 °C) and storage (80 °C to 140 °C) to paving and overheating (120 °C to 200c°C) temperature conditions (filled circles). Asphalt’s life cycle and temperature-dependent emissions. (A) Presto, Drew R.
The regulation will cover 360 businesses representing 600 facilities and is divided into two broad phases: an initial phase beginning in 2012 that will include all major industrial sources along with utilities; and, a second phase that starts in 2015 and brings in distributors of transportation fuels, natural gas and other fuels.
The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. ARB will also consider projects outside of these areas, to the extent that they provide clear and direct support to its mission.
That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development. more stringent requirements applicable to ships in Emission Control Areas (ECA).
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. While California’s population is less than 0.5%
The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. These reductions have occurred while California’s economy has continued to grow.
The California Air Resources Board released its proposed greenhouse gas cap-and-trade regulation. A key part of ARB’s AB 32 Scoping Plan ( earlier post ), the cap-and-trade program provides an overall limit on the emissions from sources responsible for 85% of California’s greenhouse gas emissions. Allowance Distribution and Trading.
California has already cut anthropogenic black carbon emissions by more than 90% since the 1960s, and existing measures are projected to cut mobile source emissions by 75% and total anthropogenic emissions by nearly 60% between 2000 and 2020. CO 2 remains in the atmosphere for up to a century.
They focused their comparison on techniques used in a three-dimensional model commonly used by environmental agencies to simulate ozone, particulate matter, and atmospheric acid concentrations, and develop effective emission reduction strategies. Stockwell, Emily Saunders, Wendy S. Goliff & Rosa M.
Given the beneficial emissions and cost analysis, combined with China’s previous experience transitioning away from CFC-12, there are no vehicle-production barriers preventing a complete phase-out of HFC-134a in the China light-duty vehicle fleet during the five-year period between 2020 and 2024.
Alliance for Pulp & Paper Technology Innovation (APPTI) (formerly Agenda 2020 Technology Alliance) will partner with NREL and ORNL to improve pulp yield during kraft pulping process in a project titled “Molecular Modeling to Increase Kraft Pulp Yield”. The project will be fully funded by the Vehicle Technologies Office.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
Implementing these approaches, the report finds, would reduce greenhouse gas and other harmful emissions from diesel-powered ships, trucks and other port equipment. Many ports and related freight corridors and facilities are located in nonattainment or maintenance areas for EPA’s ozone and PM 2.5 Click to enlarge.
The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., Within three years of enactment, the EPA would need to determine the lifecycle greenhouse gas emissions of all transportation fuels and determine the fuel emission baseline.
The achievement of this goal should be extended from 2015 to 2020 in order to have sufficient time to carry out R&D on this stretch goal. 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.
The Environmental Protection Agency (EPA) announced a new review of the Ozone National Ambient Air Quality Standards (NAAQS). EPA established the current standards at a level of 70 parts per billion in 2015 and retained them in 2020, after concluding that there was little new information to suggest the need for revision.
Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.
The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The 2013 Scoping Plan update lays out the remaining steps to the 2020 limits set by AB 32. Background.
In addition to the direct benefits of storing carbon, wood products have also been shown to have fewer associated greenhouse gas emissions compared with concrete or steel. ozone depletion potential (ODP). photochemical ozone creation potential. The sale of carbon offsets supports the gas collection and flaring project.
This highlights the potential of co-beneficial solutions to climate change that not only curb greenhouse gas emissions but also reduce the health burden of harmful air pollution. —Daniel Peters, a climate scientist with the EDF, formerly of Northwestern and lead author of the new study. Peters, D. Schnell, J. Kinney, P.
Carefully choosing how we reduce greenhouse gas emissions will have the added benefit of reducing global health inequities. Climate change due to emission of greenhouse gases from fossil fuel energy sources causes air pollution by increasing ground-level ozone and concentrations of fine particulate matter. —Kirk R.
Air pollution monitoring by the Houston Health Department in 2019 and 2020 recorded levels of formaldehyde, a known carcinogen, along the Houston Ship Channel that pose potential health risks to surrounding neighborhoods. parts per billion. Long-term exposure to formaldehyde can cause certain types of cancers.
ORNL will partner with Agenda 2020 Technology Alliance, a consortium focused on the paper industry to design better catalysts for lignin breakdown in a project titled “Catalytic Pulping of Wood.”.
Deploy more than 100,000 zero-emission vehicles/equipment and maximize near-zero by 2020. Key components of the Action Plan include: A long-term 2050 vision and guiding principles for California’s future freight transport system. Improve freight system efficiency 25% by 2030.
