BACKGROUND: Regulatory analyses of air pollution policies require the use of concentration–response functions and underlying health data to estimate the mortality and morbidity effects, as well as the resulting benefits, associated with policy-related changes in fine particulate matter ≤2:5 lm (PM 2:5 )].Common practice by U.S. federal agencies involves using underlying health data and concentration–...

BackgroundTraffic related air pollution (TRAP) is associated with a complex and diverse array of health effects. It is unknown whether these effects may be reflected by higher health care costs.ObjectivesEvaluate the association between TRAP exposure and direct health care costs in an elderly population.MethodsThis multi-ethnic population-based cohort of 25,684 elderly subjects, served by Kaiser P...

Authors evaluated the sensitivity of estimated PM2.5 and NO2 health impacts to varying key input parameters and assumptions including: 1) the spatial scale at which impacts are estimated, 2) using either a single concentration–response function (CRF) or using racial/ethnic group specific CRFs from the same epidemiologic study, 3) assigning exposure to residents based on home, instead of home and w...

The report finds that at least one in six Illinois residents now lives within half a mile of a large warehouse of at least 100,000 square feet. Other key findings include:More than 2 million Illinois residents – at least one in six – live within half a mile of a leased warehouse of at least 100,000 square feet.Of those, 127,000 are under age five and 251,100 are over age 64.At least 525,000 freigh...

Air Tracker makes visual connections between the air you are breathing and the location of air pollution sources in your city. Users can view source areas, which show where air pollution comes at any time....

MethaneSAT is the world’s most advanced methane tracking satellite. It can detect methane – a powerful greenhouse gas – at multiple scales and from multiple sectors with unmatched accuracy and precision. It will give us the most comprehensive accounting of total global methane emissions and identify where emissions are coming from, how much is being emitted and how those emissions change over time...

Recognising the important role sustainable urban logistics plays in tackling the biggest climate and sustainability challenges, Environmental Defense Fund Europe is taking action — action that starts with building consensus amongst the key players. This report and accompanying templates serve as an important tool for creating a stakeholder engagement group and using this group to develop succ...

Organizing air quality monitoring and initiating enforcement activities with the city and local level environmental authorities play a key role in improving China’s air quality. However, existing air quality monitoring networks and enforcement systems are still far from being effective and efficient.The Cangzhou pilot project, organized by Environmental Defense Fund China, Cangzhou City government...

For two years, the Breathe London pilot project mapped and measured air quality across the city, demonstrating that lower-cost sensor systems and mobile monitoring are valid ways to better understand pollution.Many cities around the world have been watching the project with interest in replicating our best practices.That’s why the Environmental Defense Fund created the Breathe London Blueprint – w...

This report is the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4). The EANET data of 2015-2019 is utilized for evaluating the current status and impact of the acid deposition and air pollution in the EANET region. This report also includes the long-term analysis of the temporal trend and variation, spatial distribution, and possible impact on the eco system of acid de...
