Indoor air quality (IAQ) is becoming increasing important as building envelope efficiency improves and we learn about the health impact on building occupants. Regulations
A positive, continuous trend due to macroeconomic factors (relocation, closure of old factories, automation), to stricter regulations but also to green choices made by the sector with a view to energy efficiency, environmental sustainability and, why not, savings. ...
February 14, 2024 – Stricter new federal regulations on deadly fine particulateair pollutionin the U.S. were announced on February 7—and Harvard T.H. Chan School of Public Health research played a key role in the decision. Many studies published in recent years by Harvard Chan researchers h...
(NO₂), which is often produced from the exhaust gases from vehicles. The concentration of nitrogen dioxide had slowly increased but has been gradually decreasing since 2007. The number of cars continued to increase, but the reduction in nitrogen dioxide means that emission regulations have ...
The chapter looks at how data-driven methods, emerging technology, and public involvement can help shape and implement air quality regulations to stay up-to-date with the always-changing environment. Case studies highlight creative approaches and effective technological implementations, highlighting the ...
The evidence is in strong agreement that air pollution—predominantly the result of human activities—is one of the leading causes of death in low- and middle-income countries9, where less stringent air quality regulations, the prevalence of older, more polluting machinery and vehicles, fossil ...
Authored by CARB Board Chair Mary Nichols, the letter highlighted LA and California's leadership in air quality regulations as a reason why the City of Angels is "better prepared than ever to offer the world's best athletes the ideal environment for peak performance in 2024." ...
