A fundamental shortcoming in air pollution models

Researchers from the University of Copenhagen have discovered a surprising phenomenon in a process by which certain gas molecules produce harmful particles. The impact of this phenomenon is likely to increase in urban areas ...

Fracking likely to result in high emissions

Natural gas releases fewer harmful air pollutants and greenhouse gases than other fossil fuels. That's why it is often seen as a bridge technology to a low-carbon future. A new study by the Institute for Advanced Sustainability ...
