Try walking, cycling or taking public transport where possible
The petroleum industry is the largest industrial source of emissions of volatile organic compounds (VOCs), a group of chemicals that contribute to the formation of ground-level ozone (smog). The combustion of fossil fuels produces greenhouse gases and other air pollutants as by-products. Some petroleum industry operations have been responsible for water pollution through by-products of refining and oil spills.
Where possible, walk, ride, carpool or catch public transport rather than drive.
