Despite a decline in emissions of the main air pollutants in Europe in the period 2002–2011, around 90% of city dwellers in the European Union (EU) are exposed to PM 2.5 These EU limits or targets are in certain cases less strict than WHO guidelines. Emissions of primary PM 10 and PM 2.5 Emissions of primary PM 10 and PM 2.5
Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. —Susan Anenberg.
The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The proposal targets the production and use of HFCs, a group of “super” greenhouse gases. Source: IGSD.
The US Environmental Protection Agency (EPA) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposed updates also add emissions reduction requirements for sources of methane and VOC pollution that were not covered in the 2012 rules.
From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. The report projects that transportation-related CO 2 emissions will drop 1.5% to 7,416 Tg CO 2 Eq., 5,813 Tg CO 2 Eq.
Comparison of the potential reduction in emissions with the application of lower sulfur 0.5% While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon.
New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Recommended 2021 AQG levels compared to 2005 air quality guidelines. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), Source: WHO.
Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.
In 2013, 87% of the world’s population lived in areas exceeding the World Health Organization (WHO) Air Quality Guideline of 10 μg/m 3 PM 2.5 Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% An additional 217,000 deaths were attributable to long-term ozone exposure.
This incorporated satellite data, ground-level monitoring measurements and data on pollution emissions from key sources, as well as modeling of how pollution drifts in the air. The 2005 “WHO Air quality guidelines” offer global guidance on thresholds and limits for key air pollutants that pose health risks. WHO PM Guideline Values.
The European Environment Agency’s (EEA’s) “ Air quality in Europe — 2019 report ” shows that almost all Europeans living in cities are still exposed to air pollution levels that exceed the health-based air quality guidelines (AQGs) set by the World Health Organization (WHO). About 8% of the urban population in the EU-28 was exposed to PM 2.5
and tropospheric ozone. Ozone accounted for about 472,000 early deaths in 2017. More than 90% of people worldwide live in areas exceeding the WHO Guideline for healthy air. Numbers of deaths attributable to air pollution in countries around the world in 2017. Ambient PM 2.5 accounted for 2.9 million deaths.
As a result of these findings, the researchers say that national governments and international agencies must take urgent action to reduce air pollution, including re-evaluating legislation on air quality and lowering the EU’s current limits on the annual average levels of air pollution to match the WHO guidelines. in the EU is 25 ?g/m
Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). However very few studies include water use impacts.
Seven billion people, more than 95% of the world’s population, lived in areas exceeding the WHO Guideline for healthy air in 2016, according to a new global study. concentrations to the WHO Air Quality Guideline. Population-weighted seasonal average ozone concentrations in 2016. Fifty-eight percent lived in areas with PM 2.5
of all global deaths) caused by outdoor fine particulate air pollution and an additional 215,000 deaths from exposure to ozone. Our study highlights the urgent need for even more aggressive strategies to reduce emissions from coal and from other sectors. They found that in 2013 there were 2.9 million deaths (5.3%
