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. The temperature data are from the Copernicus Climate Change Service (2017). Shi and Brasseur.
“There is evidence that fossil fuel subsidies are socially inequitable, that they encourage smuggling and waste, and distort economies in ways that undermine economic efficiency while harming the environment and the climate,” wrote Jim Krane, the Wallace S.
In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.
In California, reductions in emissions of black carbon since the late 1980s—mostly from diesel engines as a result of air quality programs—have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a study examining the impact of black carbon on California’s climate.
HFCs are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas. California is required to reduce HFC emissions 40% below 2013 levels by 2030 under Senate Bill 1383.
Although large emissions cuts are urgently needed to achieve globalclimate goals, it may take decades before we can measure the effect of the reductions on global temperature evolution, according to a new study by researchers at Norway’s CICERO Center for International Climate Research. Samset, Jan S.
Diesel generators release greenhouse gases, particulate matter (PM), volatile organic compounds (VOCs), nitrous oxides (NO x ) and sulfur dioxide (SO 2 ), harmful pollutants that create smog and exacerbate respiratory conditions. Emissions from these backup generators can harm local residents, regional air quality and the globalclimate.
the distribution of black carbon in the atmosphere and determine its role in the climate system. Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’sclimate impact.
However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. Global and regional-mean temperature responses to identical aerosol emissions in different regions.

Global electric vehicle market growth is projected to rise from 1.7 New Energy Nexus is an international non-profit that supports clean energy entrepreneurs with funds, accelerators, and networks.
A “well-to-wheel” life cycle assessment (LCA) by a team from synthetic fuels producer Greyrock ( earlier post ), and the National Renewable Energy Laboratory (NREL) has determined the potential reduction of greenhouse gases and criteria pollutant emissions from the use of synthetic fuels directly converted from flare gas. billion liters (18.8
The finding could further complicate attempts to model climate change. The team showed that the effect of aerosols on the climate since industrialisation depends strongly on what the atmosphere was like before pollution, when aerosols were produced only from natural emissions. —Carslaw et al. —Professor Carslaw.
” greatly understates the value that electric vehicles bring to us in terms of reducing pollution causing both global warming and severe health problems. We absolutely need to reduce the number of vehicles on our roads and overall VMT to meet our climate goals, and public transit is a key way of doing that. (Not
Policies incentivizing the private sector to push to develop innovative “clean” technologies are likely to play a key role in achieving climate stabilization. Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.). c personnel and organizational innovative capacity. —Taylor 2012.
The researchers also sampled the grime to analyze its composition, revealing that 92% was dust while the remaining fraction was composed of carbon and ion pollutants from human activity. Having previously analyzed pollutants discoloring India’s Taj Mahal, Bergin already had a good idea of how these different particles react to sunlight.
Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. —Cappa et al. Earlier post.).
Many countries regulate ozone because of the damage the pollutant does to plants and people. Since the 1990s, tighter controls on emissions of those ingredients have lessened ozone pollution in many European and US cities. The researchers think the harmful effects of surface ozone pollution are much less recognized. 8b00366.
A new study by led by Nadine Unger at NASA’s Goddard Institute for Space Studies (GISS) that analyzes the net climate impacts of emissions from economic sectors rather than by individual chemical species has found that on-road transportatation is and will be the greatest net contributor to atmospheric warming now and in the near term.
Today, here in the South Bay of Los Angeles where I live, we have all the dots you’d ever need to connect the crisis level of global warming to the urgent action needed locally. If we continue our head-in-the-sand, business as usual path, we are headed straight for runaway, uncontrollable destruction of our livable climate.
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. This plan will also help reduce nitrous oxide, a potent greenhouse gas, and fine particle pollution.
Global sales of passenger vehicles increased from 75.4 The auto industry’s production capacities are far from fully used; PricewaterhouseCoopers (PWC) estimates current global vehicle assembly capacity at almost 95 million, the report notes. Rising sales translate into an ever-expanding global vehicle parc. million to 78.6
signed SB 1383 , establishing the nation’s toughest restrictions on super pollutants including black carbon, fluorinated gases and methane. The law is in addition to California’s existing raft of climate legislation. Black carbon, for example, has a global warming potential 3200 times that of CO 2 on a 20-year time scale.
They monitored indoor and outdoor ozone levels, along with other pollutants. In contrast, only 31 million Americans live in counties where other pollutants exceed EPA standards. The production of ozone globally will be exacerbated by a warmer climate, so it will be an increasing trend with climate change, said Zhang.
Together, the US and China account for more than one third of global greenhouse gas emissions. The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015.
This method avoids using additional chemicals, offering a high efficiency, pollution?free The global demand for lithium has dramatically increased during the past decade, mostly due to the rapid growth of lithium-ion battery markets from portable electronics to large scale electric vehicles and electric energy storage applications.
After growing by more than 2% in 2019, global gas use is set to fall by around 4% in 2020, as the COVID-19 pandemic reduces energy consumption across the global economies. The report shows that medium-term growth will come from increasing cost-competitiveness and increased global access to gas.
