Climate change will further increase not only the frequency but also the intensity of extreme weather events. As a result, weather conditions favouring pneumonia occurrence - suddenly warmer weather during cold seasons - can increase due to higher meteorological variability which is also linked...

This paper empirically studies how emission pricing affects capital replacement and adoption of embodied environmental technology. A pricing policy encourages firms to accelerate retirement of old capital assets and replace them with newer more efficient assets, but this may crowd out...

The long-term trend of background O3 in surface air over the United States from 1980 to 1998 is examined using monthly probability distributions of daily maximum 8-hour average O3 concentrations at a large ensemble of rural sites. Ozone concentrations have decreased at the high end of the...

Linear Air is an air taxi start-up established to take advantage of the emergence of Very Light Jets, which incorporate new technology that cuts jet operating costs by about 40%. Air taxis could make use of the 5400 smaller regional airports throughout the US, potentially revolutionizing air...

Despite negative public perception and misleading portrayals, American air quality has improved dramatically. The United States has made dramatic progress in reducing air pollution over the last few decades, and most American cities now enjoy relatively good air quality. But polls show that most...

This work examines the techno-economic viability for replacing, in remote Northern Canadian villages not connected to the grid, local diesel generation systems with a wind turbine potentially combined with compressed air energy storage and/or CO2 direct-air capture systems. The compressed air...

This database includes annual information on CO₂ emissions related to commercial passenger and freight flights, on both a territory and a residence basis, for 186 countries. These CO₂ emissions are estimated by the OECD, based on a consistent methodology across countries.

Greenhouse gases refer to the sum of seven gases that have direct effects on climate change : carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). The...

Emissions of pollutants and gases from human activities have many negative effects on the local, regional and global environment. Greenhouse gas (GHG) emissions exacerbate the natural greenhouse effect, leading to temperature changes and other consequences for the earth's climate. Air pollutants...
