BASF has launched UpCore, a new service providing a cost-effective and sustainable technology upgrade from a standard ozone converter to an ozone-VOC (volatile organic compounds) converter for cleaner and healthier aircraft cabin air. The air at high altitude contains significant levels of ozone.
Widespread use of electric vehicles (EVs)—including lawn and garden equipment and heavy industrial equipment such as forklifts—could improve air quality, particularly in densely populated urban areas. This research points to the importance of two fundamental and parallel trends in energy and the environment.
For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. 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. emissions by more than 20%.
Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
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.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. HEI receives balanced funding from government and industry.
in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. These programs cover transportation fuels, industrial emissions, vehicle emissions and emissions from electricity generation.
The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants. Click to enlarge.
ABuilding on the proposed stronger ambient air quality standards for ozone ( earlier post ), EPA will develop a strategy for a cleaner and more efficient power sector, with strong emission reduction goals for SO 2 , NO x , mercury and other air toxics. Improving Air Quality. Other themes include: Assuring the Safety of Chemicals.
for China, reflecting regional differences in industrial development and per capita emissions. The variation is a reflection of regional differences such as industrial development, per capita emissions and geography. Despite large populations, Indian cities seem cleaner in terms of NO 2 pollution than the study’s other regions.
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.
The regulation sets a statewide limit on sources responsible for 85% of California’s greenhouse gas emissions and establishes a price signal needed to drive long-term investment in cleaner fuels and more efficient use of energy. the destruction of existing stores of ozone-depleting substances in the U.S. —ARB Chairman Mary D.
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. national ambient air quality standards (NAAQS).

The Green Aviation Summit is highlighting the depth and breadth of NASA’s work to develop aviation technologies that are designed to make air transportation cleaner and quieter for the environment, with fewer delays for travelers.
The program will cover the major sources of GHG emissions in the State, including refineries and power plants, industrial facilities, and transportation fuels. Starting in 2012, the program will cover electricity generation, including imports, and large industrial sources and processes with annual GHG emissions at or above 25,000 MTCO 2 e.
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. The production of heat for buildings or industrial processes accounts for about 30% of American energy demand.
With the reduction in on-road black carbon, regulators are turning to focus on off-road mobile, fuel combustion in the industrial and power sectors, and woodstoves and fireplaces. More than three-quarters of HFC emissions in California come from the use of refrigerants in the commercial, industrial, residential, and transportation sectors.
HEI is an independent, non-profit research institute funded jointly by the US Environmental Protection Agency (EPA) and the worldwide motor vehicle industry. Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies. Earlier post.)
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.
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.
A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Researchers from the University of California, Berkeley , found that between 2018 and 2022, CO2 emission from all sources (industries, homes, traffic) across the San Francisco Bay Area dropped around 1.8%
Well, taking carbon dioxide out of the atmosphere and potentially other gases like methane is a really sensible concept in principle because that would accelerate the process of moving back to the sort of pre-industrial sustainable climate that we have. So that’s one class. It’s very low concentration. That’s called stratospheric warming.
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.
