There are many links between Air quality and Climate change. Although air contaminants and greenhouse gases have very different environmental and human health impacts, they do share a complex relationship when it comes to the sources of emissions and their balance in the atmosphere.

Air contaminants are a set of air pollutants that cause smog, acid rain and many other negative environmental and human health effects. Air contaminants often have localized environmental and human health impacts. The most common air contaminants are Particulate Matter (PM), Carbon monoxide CO), Sulphur Oxides (SOx) and Ammonia (NH3). Climate Change refers to the global warming of the earth, caused by human activities releasing an overabundance of greenhouse gases into the atmosphere.  The Greenhouse Gases (GHGs) that contribute to climate change are often thought of as having a larger global effect. The most abundant greenhouse gases are Carbon Dioxide (CO2), Nitrous Oxide (N2O) and Methane (CH4).

Many of the sources of Greenhouse Gases and Air contaminants are shared, so taking measures to reduce Greenhouse Gases may have the added benefit of reducing air contaminants, and vice versa. Climate change mitigation actions can help reduce air pollution, and clean air measures can help reduce GHG emissions. By taking steps to improve air quality and jointly achieve greenhouse gas reductions, we are able to reduce both the local and global impacts and possibly have a larger impact on both.
