Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. Reducing tropospheric ozone can improve public health as well as agricultural productivity. The US, Canada, and Mexico provided their support for this strategy through a separate, but similar North American proposal.

Study finds children’s exposure to urban air pollution results in early hallmarks of Alzheimer’s

Green Car Congress

A study by researchers from the US, Mexico and Canada has found that children’s urban air pollution exposures result in systemic and brain inflammation and the early hallmarks of Alzheimer’s disease (AD). In the US, 200 million people live in areas where pollutants such as ozone and fine particulate matter exceed the standards.
