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.
On 6 March 2020, the California Air Resources Board (CARB) proposed to set an intermediate FTP NO x emissions limit of 50 mg/bhp-hr in model years 2024-2026 with a final FTP standard of 20 mg/bhp-hr in 2027, representing a 90% reduction below today’s standard of 200 mg/bhp-hr.

(Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications. removal; it showed about 95 % O 3.
The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. It is estimated that heavy-duty trucks will be responsible for one-third of NO x emissions from the transportation sector in 2025.
The California Air Resources Board announced $3.7 million to fund air quality improvement programs that will pay for cleaner equipment such as hybrid truck and buses, zero-emission and plug-in hybrid cars, and motorcycles. Cleaner vehicles reduce California smog and climate change emissions, and save consumers money.
million in additional California Air Resources Board (CARB) funding to replace heavy-duty trucks through the Valley Air District’s grant program. The District’s successful truck incentive programs have repowered, retrofitted, or replaced more than 7,300 heavy-duty trucks with cleaner alternatives. standards.
VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants. The reason is simple: cars are getting cleaner. —lead author Carsten Warneke, Ph.D., Warneke, C., de Gouw, J. Holloway, J.
The California Air Resources Board on Thursday adopted the final greenhouse gas (GHG) emissions cap-and-trade regulation. the destruction of existing stores of ozone-depleting substances in the U.S. Earlier post.) mostly in the form of refrigerants in older refrigeration and air-conditioning equipment). Final regulation order.
Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).
The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. Regulations and cleaner technologies have steadily improved air quality in the United States.
The California Air Resources Board approved changes to an existing $28 million financial assistance program this week that will significantly help more California independent truckers qualify for the purchase of a cleaner-running vehicle.
Alternative-fuel technology company ROUSH CleanTech has developed the first available propane autogas engine certified to California Air Resources Board’s (CARB’s) optional low oxides of nitrogen emissions standard for heavy-duty engines with 0.02 The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2
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%.
The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. As transportation gets cleaner, those other sources become more and more important. —Brian McDonald, corresponding author.
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). EPA said it is closely following the technical work initiated by the California Air Resources Board (CARB) to update the CARB heavy-duty vehicle and engine programs under a Heavy-Duty NO x Omnibus proposal.
The California Air Resources Board released GHG emissions data for 2018 showing that emissions remain below 1990 levels but are effectively flat compared to 2017, while the economy grew by 4.3%. Source: California Air Resources Board (ARB). Total statewide 2018 GHG emissions were 425.3 million metric tons, compared to 424.5
At its meeting in Sacramento yesterday, the California Air Resources Board (ARB) endorsed the state’s cap-and-trade regulation. The “cap”—which declines each year—limits GHG emissions, and uses allowances to control total emissions; one allowance equals one ton of GHGs. ARB Staff presentation on Cap-and-Trade Program.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. Finally, the State should provide incentives to accelerate market transitions to cleaner technologies that foster significant system-wide solutions to cut emissions of SLCPs.
Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
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.
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 They are available only for new natural gas and propane vehicles that meet all the emission requirements of the California Air Resources Board.
The California Air Resources Board (ARB) staff has published a discussion draft of a. ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right).
This finding is in stark contrast to previously released CE-CERT data and a recently released report by the California Air Resources Board that found heavy-duty diesel trucks emitted higher levels of NO x than their certification standards in the same duty cycles. g/bhp-hr emission target and averaged between 0.014 and 0.002 g/bhp-hr.
The California Air Resources Board directed its staff to take steps to provide further locomotive and rail yard emission reductions beyond those achieved by existing US Environmental Protection Agency and state regulations and agreements. NO x helps create ground-level ozone, or smog. Source: Staff presentation.
In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. The authors emphasized that their findings do not specifically address an individual’s health risk or the personal benefits of cleaner air, but rather assess population level health impacts. Cromar, Laura A.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Damages from electricity generation. Hidden Costs of Energy: Unpriced Consequences of Energy Production and Use.
The California Air Resources Board released its proposed greenhouse gas cap-and-trade regulation. Implementation of the program will, however, shift investment and growth within the overall economy toward those sectors driven by the production of cleaner and more efficient technologies. Offset Protocols. Transportation fuels.
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).
On their 100+ mile round trip, these trucks burn diesel fuel that damages the ozone, spews out noxious particulates that seek-out lungs and eyes along with oxides of nitrogen that help create smog, along with other nasty—and toxic—unpleasantness. How much cleaner could the air be if, instead of 50 trucks, it is 500, 1,000 or 10,000.
Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies. —Bob O’Keefe, Vice President of HEI and Chair of Clean Air Asia. Advanced Collaborative Emissions Study (ACES).
As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. Achakulwisut et al.
The researchers used tropospheric NO 2 columns retrieved from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, which measures NO 2 throughout the atmosphere in the afternoon around the world. Despite large populations, Indian cities seem cleaner in terms of NO 2 pollution than the study’s other regions. Resources.
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 Air Resources Board is required to update the Scoping Plan every five years. Transportation.
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, like i said in the first place, for me, this makes me think of one step in the right direction and makes me think of a greener cleaner future.
The US Environmental Protection Agency (EPA) is proposing to retain, without changes, the existing, more stringent 2015 National Ambient Air Quality Standards (NAAQS) for ozone. From 2017 to 2019, ozone concentrations fell 4%. During that same time, national average ozone concentrations have dropped 25%. Background.
