Above all, unsustainable transportation is especially problematic because it utilizes the most liquid hydrocarbons, such as petroleum than any other industry. The incomplete gasoline combustion creates emissions and other pollutants that include carbon monoxide, hydrocarbons, nitrogen oxides, lead, and particulate matter. In addition, transport also creates noise pollution and contaminates urban areas with carbon dioxide which can be toxic to people.
Nonetheless, this is not to say that we must abandon transportation and travel altogether, adversely we must continue to push sustainable solutions in this sector so that our demands are met without harmful effects on the environment.
Alternative fuel sources
The most obvious development must happen in the fuel source. We can start eliminating the emissions produced by combustion engines now with alternative fuels. Some examples of these fuels include biodiesel, electricity, bioethanol, hydrogen, propane or nitrogen.
More efficient engines
If petroleum needs to remain in use for the transition period to alternative methods, it should be done while seeking the highest efficiency of the combustion engine.
Alternative ways of transportation
We should also strive to make a shift from cars and other petroleum-using vehicles but instead opt for public transport or bicycles. Pooling of passengers per vehicle considerably lowers the demands on fuels.
