Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.
Illustration of projected ozonechanges in the South Coast region due to climatechange in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. Our study reveals that climatechange and regional air pollution are intertwined problems. Click to enlarge.
The climatechange benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climatechange. Click to enlarge. Both near-term and long-term strategies are essential, the report concludes.
Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climatechanges, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.
Schematic diagram of the trade-offs between the implications for regional air quality and global climatechange of new policies for management of the atmosphere. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs. Source: NOAA. Click to enlarge.
the final version of the proposed First Update to the ClimateChange Scoping Plan (First Update). Achieving our long-term climate goal and 2032 ozone standards will require a much deeper penetration of ZEVs into the fleet. The California Air Resources Board (ARB) has released. The draft version was released in February.
The California Air Resources Board is accepting applications for the 2014 Haagen-Smit Clean Air Awards. The awards are annually bestowed upon scientists, policy makers, community leaders and educators who have made outstanding contributions to the advancement of clean air and climatechange science, technology and policy.
The study will appear next month in the peer-reviewed journal ClimaticChange Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climatechange have been difficult to calculate.
Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climatechange mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.
The issuance of an endangerment finding enables the regulation of greenhouse gases under the Clean Air Act. Combined with the endangerment finding, this enables the regulation of greenhouse gas emissions from motor vehicles under the Clean Air Act. In both magnitude and probability, climatechange is an enormous problem.
Selin and colleagues compared the health benefits to the economic costs of three climate policies: a clean-energy standard, a transportation policy, and a cap-and-trade program. In 2011, 231 counties in the US exceeded the EPA’s regulatory standards for ozone, the main component of smog. ClimateChange Emissions Health Policy'
Policies incentivizing the private sector to push to develop innovative “clean” technologies are likely to play a key role in achieving climate stabilization. Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.). and NO 2 regulation in the US in 1970. Taylor 2012.
For its part, EPA is withdrawing the Clean Air Act preemption waiver it granted to the State of California in January 2013 as it relates to California’s GHG and ZEV programs. California’s ability to enforce its Low Emission Vehicle program and other clean air standards to address harmful smog-forming vehicle emissions—i.e.,
The seven themes are: Taking Action on ClimateChange. EPA will finalize its mobile source GHG rules under the Clean Air Act, and “ provide a framework for continued improvements in that sector.” ( Earlier post. ). Cleaning Up Communities. Improving Air Quality. Other themes include: Assuring the Safety of Chemicals.
The cap-and-trade joins a suite of other major climate program measures including standards for ultra-clean cars (Advanced Clean Cars, earlier post ), low-carbon fuels (Low Carbon Fuel Standard, earlier post ) and renewable electricity. the destruction of existing stores of ozone-depleting substances in the U.S.
while the US GDP is projected to grow by 40%, according to the fifth National Communication on US climatechange actions submitted by the US Department of State to the United Nations Framework Convention on ClimateChange. The United States released previous Climate Action Reports in 1994, 1997, 2002, and 2006.
The US Environmental Protection Agency (EPA) has submitted its final Report to Congress on Black Carbon , in response to an October 2009 request from Congress to advance efforts to understand the role of black carbon (BC) in climatechange. Effects of BC on climate, as compared to GHGs. Earlier post.). Earlier post.).
Development of sustainable communities strategies can also provide an opportunity for associated criteria pollutant emission reductions that will be needed to attain air quality standards for ozone and particulate matter as well as reduce near-roadway exposures.
Funding priorities through the ARFVT Program support fuel and vehicle development to help attain the state’s climatechange policies. 5 million for light-duty plug-in electric vehicle rebates to meet high demand for the Clean Vehicle Rebate Program, administered by the California Air Resources Board. $5
On the first day of a two-day board meeting—the second day of which (Friday 24 March) will consider the Advanced Clean Cars Midterm Review—the California Air Resources Board (ARB) took a number of climate and air quality actions. emissions by more than 20%. emissions by more than 20%.
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.
The data showed a 50% jump in efficiency each time the panels were cleaned after being left alone for several weeks. The manmade particles are also small and sticky, making them much more difficult to clean off. If cleanings take place every two months, those numbers jump to 25 or 35%. —Michael Bergin.
The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., A transitioning title intended to protect US consumers and industry and promotes green jobs during the transition to a clean energy economy. Clean Fuels and Vehicles.
Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels. Vehicle Integration.
The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate. Unger et al. Click to enlarge. Unger et al. Resources.
Currently, the Clean Air Act limits the volatility of gasoline to 9.0 psi RVP in southern ozone non-attainment areas—but allows a 1 psi RVP waiver for E10. Thus, the evaporative emission increase caused by E30 would then be less than for E10. psi RVP and 7.8 This waiver applies only to E10 (E9-E10), not more, not less.).
The leaders of the world have just returned from the UN's latest climatechange summit, COP26 , in which the countries that have signed on to the Paris Agreement upped their commitments to fight climatechange. IEEE Spectrum : What role does Silver Lining play in climate research or advocacy? In 2015, the U.S.
Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climatechange could be avoided through 2050 by transitioning to low-GWP alternative MACs.
The allocation system is designed to reward those who have taken early action and have invested in energy efficiency and GHG emissions reductions and will encourage continued investment in efficiency and clean energy in the future.

SLCPs may account for an estimated 40% of global warming, increasing the impacts of climatechange. Research now shows that immediate action to cut super pollutants in California will reduce damage to forests and crops, lower background ozone and help clean the air in the state’s most polluted regions, including the Central Valley.
As we confront the enormous challenge of climatechange, we should take inspiration from even the most unlikely sources. 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.
It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climatechange. The analysis also looked at the impact of climatechange on human health and suggests that it may lead to higher levels of ground-level ozone, a harmful pollutant.
In 2004, the Centralina region (the Greater Charlotte metro area, which straddles the North CarolinaSouth Carolina border) was designated as a non-attainment area for ozone under the Clean Air Act. The area stood to lose billions of dollars of federal funding for a wide variety of projects if the areas air quality didnt improve.
Eliza Strickland: Man-made climatechange is already reshaping our planet, and carbon emissions aren’t coming down fast enough to stave off real disaster in the decades to come. It’s often called geoengineering in the popular press, but the preferred term is climate intervention. It’s one of the key questions in climate science.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climatechange problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
Global warming plays a role in thinning the ozone layer, thus permitting harmful rays’ penetration to the earth. This organisation is responsible for addressing climaticchanges and how to cope with them. Empower households to make better choices- the climate is mainly affected by our daily lives.
The climatechange benefit is estimated for a given year (2050) and human health and crop benefits are. 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
What I do know, is how fossil fuel vehicles have contributed heavily to poor air quality in our towns and cities, damage to the environment, soil and water quality and have contributed to the depletion of the ozone layer! Maybe, by contrast the Tesla shouts ‘look I’m doing it!’ Don’t you get range anxiety?…
Circle areas are proportional to values for (A and B) climatechange, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.
Global benefits from full implementation of measures for reduction of short-lived climate pollutants in 2030 compared to the reference scenario. The climatechange benefit is estimated for a given year (2050) and human health and crop benefits are. for 2030 and beyond. Source: UNEP. Click to enlarge. Earlier post.).
The studies use case studies to demonstrate the co-benefits of tackling climatechange in four sectors: electricity generation, household energy use, transportation, and food and agriculture. Climatechange threatens us all, but its impact will likely be greatest on the poorest communities in every country.
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. However, to achieve the needed transportation GHG reductions and the corresponding 2032 ozone standards, the market uptake of advanced technologies will need to be accelerated. Transportation.
In October 2007, Governor Arnold Schwarzenegger signed AB 118 which provides approximately $200 million annually through 2015 to the California Energy Commission, the Bureau of Automotive Repair and the ARB to fund air quality improvement projects that will accelerate clean engine technologies. ARB was appropriated approximately $42.3
