Recycling Bin.
These steps include: reducing toxic emissions from industrial sources; reducing emissions from vehicles and engines through new stringent emission standards and cleaner burning gasoline; and addressing indoor air pollution though voluntary programs.
By reducing our consumption of energy, we decrease the amount of industrial activity which causes air pollution in the first place. Other measures such as taking public transportation reduces the amount of fossil fuels and, by extension, reduces the amount of NOx, SOx, and hydrocarbon pollution.
