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
A study by a team of researchers from China, the US and Germany suggests that future climate 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. and ozone exposure, respectively.
Schematic diagram of the trade-offs between the implications for regional air quality and global climate change of new policies for management of the atmosphere. The project builds upon the idea that air quality and climate change issues are linked through “one atmosphere”, an approach that demands coordination and multi-tiered approaches.
Impact pathway approach for modeling policy interventions in (a) air quality and (b) climate impacts. Around 2,045 avoided premature deaths in greater Dhaka can be attributed to air quality improvements from the CNG conversion policy in 2010, resulting in a saving of around US$400 million, they found.

Climate change threatens us all, but its impact will likely be greatest on the poorest communities in every country.
The new standards would require new heavy-duty diesel vehicles sold after 1 January 2018 to meet emissions standards equivalent to those in the United States (EPA 2010) and European Union (Euro VI). And the climate benefits of the reductions in black carbon emissions are also a great step forward. emissions in urban areas.

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.
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. California’s Climate Protection Strategies do not help meet NAAQS Standards. Background.
California will meet its 2030 climate targets more than three decades late, in 2061, and could be more than 100 years late in meeting its 2050 target if the average rate of emissions reductions from the past year hold steady, according to a new study tracking more than a decade of environmental and economic indicators in the state.
The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”.

This second workshop will go into more detail in several areas related to criteria pollutant emissions and greenhouse gas emissions.
Effective January 2010, Brazilian diesel fuel vehicles will be required to run on a 5% biodiesel blend, up from 4% at present. billion liters (634 million gallons) in 2010. The announcement was made last Friday by president Luiz Inácio Lula da Silva and is expected to raise biodiesel production levels to 2.4 Emissions testing.

While the existence of higher CO 2 levels overs cities—CO 2 domes—has been known for more than a decade, their effects on local air pollution has up to now not been explored. As such, reducing locally emitted CO 2 may reduce local air pollution mortality even if CO 2 in adjacent regions is not controlled. Jacobson, 2010.
The two areas suffer from some of the worst air quality in the country due to a number of factors, such as meteorology, geography, climate and weather.
