WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

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. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. nitrogen dioxide (NO?)

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

This new study is based on a thorough review of a decade of research on aviation emissions. It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Preliminary global mean CO 2 concentrations in February 2014 were 398.06 Ozone formation. Scenario A2 and RCP 8.5.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climate change have been difficult to calculate.
