The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. These regulations have led to considerable improvements in air quality throughout California.
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution.
The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climatechange.
All the participating jurisdictions are members of the Transportation and Climate Initiative (TCI), a regional collaboration of Northeast and Mid-Atlantic states and the District of Columbia that seeks to improve transportation, develop the clean energy economy, and reduce carbon emissions from the transportation sector.

The RNG product with very low carbon intensity could be used for carbon emission reductions in the transportation, industrial, commercial, and residential energy sectors. The Gasification-powered RNG Process.
Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Maybe this unintended experiment could be used to understand better the emission regulations.

California Assemblymembers Marc Berman (D-Menlo Park) and Lorena Gonzalez (D-San Diego) introduced legislation to phase out the sale of new gas-powered small off-road engines (SORE), which are primarily used in lawn and garden equipment, including leaf blowers, lawn mowers, and other outdoor power equipment. —Assemblymember Marc Berman.
Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime. This unexpected phenomenon suggests sulfur dioxide emission reductions are less efficient than expected for cutting sulfate aerosols. These trends are expected to continue.
The report—“Combining Multiple Climate Policy Instruments: How not to do it”, points out that a Europe-wide cap on emissions under the EU Emissions Trading Scheme means that the rest of Europe will continue to emit up to this capped level whatever policy instruments are introduced at a national level.
The New Mexico Environmental Improvement Board (EIB) adopted by a vote of four to three greenhouse gas reduction regulations—called the most stringent in the US—that will reduce global warming pollutants through a regional cap on greenhouse gasemissions. New Mexico Greenhouse Gas Cap-and-Trade Regulation.
US GHG emissions allocated to systems, and by materials and land management. The Land Sink, represented by the outer ring, offset the equivalent of 13% of total US anthropogenic emissions in 2006. The entire pie chart represents total US emissions in 2006; the inner portion of the pie chart represents net emissions.

The California Air Resources Board (CARB) announced that greenhouse gasemissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
However, the fuel-cycle PM 10 , PM 2.5 , SO 2 , and NO x emissions of EVs could be up to five times higher than those of ICEVs (internal combustion engine vehicles) and CNGVs. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5 Credit: ACS, Huo et al.

The entire life cycle of the passenger cars is taken into account, including the manufacture of the vehicles and the environmentally relevant emissions from driving. The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climatechange [kg CO 2 -eq.]. in review).
The US and China jointly announced greenhouse gas (GHG) reduction targets. US President Barack Obama said the US will cut net greenhouse gasemissions in the US by 26-28% below 2005 levels by 2025. Together, the US and China account for more than one third of global greenhouse gasemissions.
The shift to electric mobility is in line with ongoing efforts to reduce the world’s dependence on fossil fuels, and reduce harmful greenhouse gasemissions responsible for climatechange. It has also contributed to environment degradation, landscape damage and soil contamination, groundwater depletion and pollution.
of the world’s total greenhouse gasemissions, there is an increased pressure for the maritime industry to transition to more sustainable power sources. Among alternative emission-free technologies, ABB is already well advanced in collaborative development of fuel cell systems for ships. With shipping responsible for about 2.5%
In addition to keeping anthropogenic CO 2 out of the atmosphere, this technology will lead to benefits and trade-offs for air pollution, according to a new report from the European Environment Agency (EEA). The report shows that while CCS may have an overall positive effect on air pollution, emissions of some pollutants may increase.
billion investment plan to support the transition to zero-emission transportation. This year’s investment dollars focus largely on underserved communities, including low-income communities and those disproportionately burdened by environmental pollution, as well as small truck fleets.

New research by a team at the NASA Goddard Institute for Space Studies (GISS) in New York suggests that gas-aerosol interactions can amplify the global warming impact of some greenhouse gases. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.
However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The aim is to better understand and predict the extent and impact of urban air pollution on Earth’s atmosphere. HALO in-hangar in Taiwan.
When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
