This report will consider the life cycle of a motor vehicle in regards to the emissions, while discussing the roles of engineers. This report finds that CO₂ emissions are continuing to rise and no step of the life cycle is exempt of pollution.
* 2. Introduction
Globally both professional and non professional engineers are involved throughout the life cycle of a motor vehicle, from the steel production, to disposal and decommissioning. With a growing global population which is increasing at a rate of 3% per annum (about.com geography, 2011). The current population is estimated to be 6,928,198,253; the use of motor vehicles is steady increasing and the reliance on fossil fuels, with 43.4% of the world’s energy consumption coming from fossil fuels (environmental literacy council, 2008).With the use of fossil fuels such as petroleum in cars, the emissions and subsequent pollution to the environment is increasing. Car exhaust is a large contributor to the emissions along with the mining or harvesting of the raw materials. Petroleum is involved in the construction of rubber, plastics and nylon. It involves the hydrocarbon burning of fossil fuels, significantly contributing to the problem. This report considers the roles of professional and non professional engineers in all steps of cycle, as well as the impacts of emissions.

3.1 Roles of Engineers
Both professional and non professional engineers are involved in a cars life cycle. Mining and harvesting raw materials, such as ore for steel and aluminium involves Civil engineers. They
