Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change.
US EPA Region 9 8-hour ozone trends, 1979-2000. These State Implementation Plans (SIPs) are the roadmaps to meeting the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) of 0.08 In 1997, EPA first established the 8-hour ozone standard, which replaced the older 1-hour ozone standard (0.12 Source: EPA.
Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences, the authors write.
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. California’s Climate Protection Strategies do not help meet NAAQS Standards. Click to enlarge.
Contribution of gasoline and diesel exhaust to SOA over 0% to 50% diesel fuel use. SOA contributions from the two sources are equivalent at 6% diesel fuel use. Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climate change. Gentner et al. Earlier post.).
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%.
GWP100 weighted specific climate impact (g CO 2 -eq per pkm) as a function of vehicle occupancy. A team from Austria and Norway has found that the climate impact from a long-distance trip (500–1,000 km, or 310–621 miles) can easily vary by a factor of 10 per passenger depending on mode choice, vehicle efficiency, and occupancy.
Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. The next round of UN climate negotiations begins in Cancun today. ” The authors go on to say that reducing the non-CO 2 pollutants can delay additional climate warming by several decades.
The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. The top sample above shows climate change impact; the subsequent chart shows human toxicity. Terrestrial toxicity [kg 1,4-DC.-eq.].

The traffic prohibitions are part of the creation of Israel’s first low-emission zone, an area restricted to polluting diesel vehicles. Diesel vehicles, while responsible for only 20% of the kilometers traveled, contribute 75% of the fine particles emitted by transportation. emissions in the region.
Funding priorities through the ARFVT Program support fuel and vehicle development to help attain the state’s climate change policies. This will support the district’s plan to replace its aging fleet of 50 diesel school buses with natural gas buses. million ZEVs on the state’s roads. The agreement includes $175,000 in match funding.
Biofuels such as ethanol, biodiesel, and renewable diesel can displace fossil fuels and reduce the amount of fossil-based CO 2 emissions released into the atmosphere. The percent of biodiesel and renewable diesel in the total diesel blend have shown a significant growth in recent years, going from 1% in 2012 to 18% in 2017.
Sustainable Communities : The Sustainable Communities and Climate Protection Act of 2008 (SB 375) directs California’s metropolitan planning organizations to develop sustainable communities strategies that meet regional greenhouse gas reduction targets through integrated land use, housing and transportation planning.
So far, ammonia has been considered as a fuel when blended with gasoline, diesel, hydrogen and methane fuels to reduce the proportion of carbon-based fuels and their emissions that contribute to climate change. Production plants already exist because ammonia is widely used in fertilizers.
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.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. From 2007 to 2008, the share of ethanol in global gasoline type fuel use was estimated to increase from 3.78% to 5.46%, and the share of biodiesel in global diesel type fuel use from 0.93% to 1.5%.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. —“Revised Proposed Short-Lived Climate Pollutant Reduction Strategy”.
Medium- and heavy-duty on-road trucks and buses are a significant source of emissions of greenhouse gases (GHG); diesel particulate matter 2.5 microns or less (PM 2.5 ); and NO x emissions that lead to ozone and secondary PM. Statewide, they are responsible for 35% of the NO x emissions, 26% of the PM 2.5
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 precursor emissions; GHG emissions; petroleum usage; and diesel toxics emissions as various technologies become widespread in vehicle and equipment fleets. Vision 2.0
The design of the California cap-and-trade program allows linkage with programs established by partner jurisdictions in the Western Climate Initiative (WCI) to create a regional market system. Tags: Climate Change Emissions Fuels Policy. The program is expected to reduce GHG emissions between 18 and 27 MMTCO 2 e in 2020.
While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon. The emissions report focuses on the low- and mid-range diversion scenarios—i.e.,
Key Steps to Cleaning Southern California’s Air Diesel Class 8 trucks run seemingly tail-to-nose from the Ports of Long Beach and Los Angeles to the Inland Empire in Southern California. Last mile trucks like Amazon’s are moving to EVs Almost all of those trucks run on diesel, but change is coming. Even the U.S.
The proposal retains the proven regulatory design of previous EPA standards for light-duty vehicles, but leverages advances in clean car technology to further reduce both climate pollution and smog- and soot-forming emissions.
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. What was the initial inspiration to have a train that runs on hydrogen instead of diesel? Thats the way diesel became widely available.
Further, the Department for Transport in the UK has declared that it will have banned all conventional petrol and diesel cars by 2030. Global warming plays a role in thinning the ozone layer, thus permitting harmful rays’ penetration to the earth. Address climate emergency- the climate is changing rapidly.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change 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.
The climate change 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
A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Black carbon Climate Change Emissions'
Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.
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!’
Climate response to non-CO 2 vehicle emissions. Bars on the right show uncertainty ranges for 2070, including contributions from both forcing and climate sensitivity (67%; CI). Bars on the right show uncertainty ranges for 2070, including contributions from both forcing and climate sensitivity (67%; CI). Shindell et al.
Circle areas are proportional to values for (A and B) climate change, (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. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health.
However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. The most immediate, effective and low-cost way to reduce soot emissions is to put particle traps on vehicles, diesel trucks, buses, and construction equipment.
A new international study has found that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50%. For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions.

TDI (diesel), both in the basic versions with standard equipment. ozone depletion potential (ODP). photochemical ozone creation potential. Click to enlarge. TSI, at 31.3
Furthermore, this would also deliver a net annual reduction of at least 200 MtCO 2 e from short-lived climate pollutants in 2030 (using GWP-100 values). Climate benefits in the near-term (estimated using a GWP-20) are more than three times as large given the rapid benefits that the control of black carbon provides. Chambliss et al.
Benefits include meeting the state’s freight infrastructure, public health, air quality and climate goals. The Executive Order directs the state agencies to pursue a shared vision to “ improve freight efficiency, transition to zero-emission technologies and increase the competitiveness of California’s freight system.
