In a statement released this morning, President Barack Obama said he has requested that US Environmental Protection Agency (EPA) Administrator Lisa Jackson withdraw the agency’s draft Ozone National Ambient Air Quality Standards (NAAQS) rulemaking. Earlier post.) National Ambient Air Quality Standards (NAAQS).
The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.
The California Air Resources Board today approved a statewide plan for attaining the federal health-based standard for ozone, typically experienced as smog. The 2022 State Implementation Plan Strategy identifies the state’s control strategy for meeting the federal 70 parts per billion, 8-hour ozone standard over the next 15 years.
million of Fiscal Year 2013 funds ( FTA-2014-001-TRI ) for the deployment of low- or no-emission (LoNo) transit buses. This program successfully committed $90 million over seven years for research, demonstration, and deployment projects to reduce the cost of fuel cells for transit use. Of that amount, $21.6 7407(d)); or.
Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. VOC emissions would have been reduced by 57 tpd. For other areas, where PM2.5
The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. NO x is a precursor for both ground level ozone and secondary PM 2.5 Source of data: US EPA (2019). Chart: MECA.

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.
Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5) IPCC WG III.
The program will demonstrate that a suite of commercially available, EPA-rail-certified engines present a near-term, low-risk solution to create an affordable RNG hybrid line-haul locomotive with near zero emissions while simultaneously improving fuel cost by 50%. g/bhp-hr of NOx, a reduction of 400 times. g/bhp-hr of PM.
By authorizing real, permanent offsets from farms, forests, and businesses that are not covered by cap-and-trade, we can reduce the costs of compliance with the program and encourage investments in sustainable practices throughout the California economy. Destruction of Ozone Depleting Substances. Urban forestry. Dairy manure digesters.
Carried long distances across the country by wind and weather, power plant emissions of sulfur dioxide (SO 2 ) and nitrogen oxide (NO x ) continually travel across state lines. The rule will improve air quality by cutting SO 2 and NO x emissions that contribute to pollution problems in other states. NO x emissions will drop by 54%.
Illustration of light-duty vehicle sales share by emission certification level projected to be required to meet. The California Air Resources Board (ARB) is developing a proposal for more stringent emission requirements—i.e., Super Ultra Low-Emission Vehicle (SULEV). proposed NMOG+NO x standards in new LEV III.
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 proposed updates also add emissions reduction requirements for sources of methane and VOC pollution that were not covered in the 2012 rules.
The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. times the cost of implementing a cap-and-trade program.
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. While we are pleased to have already reduced diesel emissions at the rail yards, it’s not enough.
The traffic prohibitions are part of the creation of Israel’s first low-emission zone, an area restricted to polluting diesel vehicles. All of these measures will lead to the goal we set for ourselves this year, to turn the city of Haifa into a low-emissions zone that will be restricted to polluting vehicles.
Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.). Policymakers rarely see with perfect foresight what the appropriate emissions targets are to protect the public health and environment—the history is that these targets usually need to get stricter.
A study led by researchers at UC Berkeley has found that diesel exhaust forms about seven times more secondary organic aerosols (SOA) than gasoline exhaust for the same mass of unburned fuel emissions and, given emission factors, can be expected to form 15 times more SOA than gasoline per liter of fuel burned.
A key barrier to achieving RFS2 is the high cost of producing biofuels compared to petroleum-based fuels and the large capital investments required to put billions of gallons of production capacity in place. Greenhouse gas emissions.
Combined with the other 25 truck deployments through the Volvo LIGHTS project, Volvo Trucks is committed to delivering nearly 100 VNR Electric trucks to the region for zero-emission freight transport. The 70 Volvo VNR Electric trucks deployed through this grant are anticipated to provide lifetime emission reduction benefits in excess of 152.63
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 The county estimates the project will result in eventual fuel cost savings of $266,764 annually.
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 climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.
Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. In particular, TPS technology offers a groundbreaking approach to reducing emissions from combustion engines and improving the environment.
The researchers characterized nanowastes and nanoparticle emissions from the SiNW synthesis. In particular, silicon nanowires (SiNW) are widely studied as a promising anode material for high-capacity LIBs due to its low cost of fabrication and volume production potential.
These standards will result in significant GHG emissions reductions and fuel efficiency improvements across all of these vehicle types. For example, when the standards are fully phased in, tractors in a tractor-trailer will achieve up to 25% lower CO 2 emissions and fuel consumption than an equivalent tractor in 2018.
Numerous studies compiled by the Environmental Defense Fund show that in addition to harming the community, diesel school buses also “self-pollute” with emissions entering the bus cabin, to the point that “ the interior cabin of a diesel bus is five times higher ” than outside the bus.
This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The SL-MAC project is on schedule, as expected, with anticipated environmental and cost advantages to be determined in the next stages. — Dr. Stephen O.
The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? Cumulative GHG emissions reductions from 2010 to 2050 can range from 3.4 billion metric tons.
The Partnership aims to “ accelerate the introduction of advanced truck and bus technologies that use less fuel, have greater fuel diversity, operate more safely, are more reliable, meet future emissions standards, and are cost effective.” The 21CTP was formed in 2001 to reduce fuel usage and emissions in trucks of Classes 3 through 8.
Electric school buses have no tailpipe emissions, so students are not directly exposed to harmful vehicle fumes when on or near the bus. Between 2022 and 2026, the CSB will distribute $5 billion to replace existing school buses with zero- or low-emission models. The CSB has two methods of funding: Rebates and Grants.
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 climate change is already reshaping our planet, and carbon emissions aren’t coming down fast enough to stave off real disaster in the decades to come. Strickland: Why don’t you focus on just cutting carbon emissions? And so the cost of that right now is really, really high. Transcript.
Counties where measured ozone is above proposed range of standards, based on 2011-2013 monitoring data. Earlier this year, EPA staff had recommended the further reduction of this primary ozone standard from the current 75 ppb (parts per billion) to a revised level within the range of 70 ppb to 60 ppb—and preferably below 70 ppb.
Counties projected to violate proposed Primary 8-hour Ground-Level Ozone Standards in 2020. The United States Environmental Protection Agency has proposed the strictest standards to date for ground-level ozone. EPA is proposing an accelerated schedule for designating areas for the primary ozone standard. Source: EPA.
At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5%
issued its final rule revising the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb) from 75 ppb to protect public health. Ground-level ozone forms when nitrogen oxides (NO x ) and volatile organic compounds (VOCs) react in the air. The US Environmental Protection Agency (EPA).
Over the next 10 years this plan will put in place not only tools to clean up VW’s excess emissions, but also to help achieve further reductions of smog-forming pollution for decades to come. The mitigation plan approved by CARB will invest primarily in zero emission replacements for heavy-duty trucks, buses and equipment.
The US Environmental Protection Agency (EPA) is proposing regulations employing the “good neighbor” provision of the Clean Air Act to reduce interstate transport of upwind state emissions from power generation that contribute to air quality problems in downwind states. NO x emissions would drop by 52%.
However, since the cost of the hydrous ethanol is significantly lower, hydrous ethanol will provide a lower cost per mile travelled, assuming the processing cost savings is passed on to the consumer. The water contained in hydrous ethanol blends also reduces NO x emissions. 40 CFR § 80.27 Pursuant to 40 CFR § 80.27(a)(2):
Vehicle electrification in the United States could prevent hundreds to thousands of premature deaths annually while reducing carbon emissions by hundreds of millions of tons. In the new study, Horton, Peters and their team looked at vehicle fleet and emissions data from 2014. Peters, D.
Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S.
Sepion envisions that successes could catalyze a transformation in aviation, in which fuel-burning aircraft are replaced with hybrid-electric planes featuring 30–50% reductions in fuel costs and emissions. Harper International Corp.
For hospitals and medical centers with an ambulatory or EMS fleet, switching from internal combustion engine (ICE) vehicles to EVs could save as much as 75% in fleet maintenance costs.
