A study by a team of researchers from China, the US and Germany suggests that futureclimate change may worsen air quality for more than 85% of China’s population, leading to an additional 20,000 deaths each year. Managing air quality in China in a changing climate will thus become more challenging. —Hong et al.
The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.
The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.
A new NOAA study covering four decades of tropical cyclones found that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere.

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
Air pollution in India resulted 1.67 million deaths in 2019—the largest pollution-related death toll in any country in the world—and also accounted for $36.8 The 2019 death toll attributed to air pollution in India accounted for 17.8% Pollution takes an enormous human toll in India. It is causing 1.67
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 climate change.
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.
A team of researchers, led by Professor Gavin Shaddick at the University of Exeter, has shown that, despite global efforts to improve air quality, half of the world’s population is exposed to increasing air pollution. An open-access paper on the research is published in the journal Climate and Atmospheric Science. (a)Map Shaddick, G.,
Aggregated damage costs by pollutant. Air pollution from the 10,000 largest polluting facilities in Europe cost citizens between €102–169 billion (US$135–224 billion) in 2009, according to a new report from the European Environment Agency (EEA) which analyzed the costs of harm to health and the environment caused by air pollution.
Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. Aviation emissions are an increasingly significant contributor to anthropogenic climate change. Aviation emissions are an increasingly significant contributor to anthropogenic climate change.
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.
Emissions from farms outweigh all other human sources of fine-particulate air pollution in much of the United States, Europe, Russia and China, according a new study published in Geophysical Research Letters , a journal of the American Geophysical Union. Pollutants other than ammonia should probably be targeted for abatement, Paulot said.
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.
Impact pathway approach for modeling policy interventions in (a) air quality and (b) climate impacts. However, CNG conversion was apparently detrimental from a climate change perspective, as CH 4 emissions increased. Motor vehicles were the major source of air pollution in Dhaka.

Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change. —Kalghatgi et al.
The President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climate change. Both approaches are essential parts of an integrated strategy for dealing with climate change.
Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.
The review is the latest product of WHO’s Health in the Green Economy initiative, which is considering available evidence on health impacts from climate mitigation strategies for key economic sectors, as reviewed by the UN’s Intergovernmental Panel on Climate Change. Carlos Dora of WHO’s Department of Public Health and Environment.
With ride-hailing services now providing more trips nationally than taxis, the growth of ride-hailing has directly contributed to increased local pollution and exacerbated traffic congestion in dense urban areas. Through electrification of vehicles and increased use of pooled rides, we can reduce the climate risks of ride-hailing services.
We do have a climate crisis that needs to be addressed. Heavier vehicles also generate more particulate pollution from tyre wear. Ultimately, to manage climate change, the world needs to stop emitting greenhouse gases from vehicles and power plants. That has a significant impact on safety for all road users. Shaffer et al.
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. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.
A climate-neutral alternative to petroleum-based fuels, they also offer the potential for significantly reduced overall emissions, allowing Tenneco’s Clean Air experts to better manage any remaining pollutants through the aftertreatment process. We are excited to be an active part in the development of this type of technology.
Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.
Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.
A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE).
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.
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.
The report is the culmination of MITEI’s three-year Mobility of the Future study, which is part of MIT’s Plan for Action on Climate Change. Understanding the future of personal mobility requires an integrated analysis of technology, infrastructure, consumer choice, and government policy.
The Transportation and Climate Initiative Program (TCI-P) expects to cut greenhouse gas emissions from motor vehicles in the region by an estimated 26% from 2022 to 2032, and generate a total of more than $3 billion dollars over ten years for the participating jurisdictions to invest.
But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. Not only can IPG’s technology deliver low-emission, pollutant-free energy on today’s cleaner fuels. This growth will require high megawatt capacities across England’s road networks.
California’s Climate Protection Strategies do not help meet NAAQS Standards. This presents a very important point: today’s very low-emitting natural gas HDVs are more than just “bridge technologies” to the future of California’s near-zero-emission heavy-duty transportation sector.

The preferred fuel path(s) will depend to a great extent on their climate and environmental performance, which is of national concern. It also assesses the strengths and weaknesses of EVs and CNGVs from a perspective of climate change and environmental impact. Fuel-cycle NO x and SO 2 emissions of EVs, CNGVs, gasoline ICEVs, and HEVs.
The people whose business model is to wreck the ecology and the climate and profit from it. These are the people who in the face of science that says we must transition from fossil fuels to renewable energy or destroy the futures of our children and all who come after them, still want to drill for oil that should never be burned.
Approximately 70 percent of Audi Hungaria’s heat requirements are already covered by climate-neutral, geothermal energy. Our goal is to have completely CO 2 -neutral plant operation in the future. We are also installing new technologies at all our plants to reduce our water consumption, avoid air pollution and improve recycling.
