Smog, acid rain and air pollution

Smog forms as a chemical reaction of carbon monoxide, nitrous oxides, volatile organic compounds and sunlight. The chemicals that make up smog are toxic to human beings, animals and even vegetation. They are also highly reactive and oxidising which means they can degrade many other materials.

Many pollutants contributeto the formation of smog, including vehicle emissions, noxious gases, solvents and paints.

Natural gas produces lower nitrous oxide emissions and no particulates or VOCs, and therefore makes a valuable contribution to preventing smog and ensuring cleaner air. In particular the wider use of natural gas in power generation, vehicle fuel and industry can help reduce the formation of smog.

Acid rain is another environmental phenomenon and one of the main sources of damage to trees and vegetation. Acid rain is caused by the reaction of sulphur dioxide, nitrous oxide, water vapour and other chemicals in the presence of sunlight. It manifests itself in the form of acidic rainfall and fallout of particles and gas.

Natural gas produces virtually no sulphur oxides and nitrous oxide emissions 0% lower than coal, and therefore helps to reduce the presence of air pollutants that cause acid rain.
