Atmospheric emissions from car exhausts contribute to poor air quality around the world. The emissions from motor vehicles have a significant impact on the global environment. Automobile exhaust is a major source of nitrogen oxide (NOx), a central component of emissions. These emissions cause low-level ozone, resulting in unhealthy air quality. Worldwide, carbon dioxide (CO2) levels are increasing each year due to the combustion of petroleum. While high oil prices and renewed concerns about energy conservation are rising, the call for new methods of transportation that enhances the balance between social, economic and environmental concerns has emerged. About 1.6 billion people depend on traditional petroleum only based vehicles, a very inefficient form of transportation that is detrimental to the global environment. Hybrid Electric Vehicles have the potential to combat these global trends and lessen the impact on the environment and the economy while reducing the U.S. dependence on foreign oil. This project evaluates the Hybrid Honda Accord with it is conventional counter part, Honda Accord in terms of fuel efficiency, production, and final disposal impacts on the environment. A detailed life cycle analysis performed reveals that increased total energy consumption, higher disposal costs, and increased production costs are necessary hurdles to producing a hybrid vehicle while offering greater emission reductions and superior fuel efficiencies. The analyses indicate that substantial green gas emission reductions are achievable. This work clearly pointed out that the combination between gasoline and electric technologies used in the Honda Accord reduce CO2 emissions by approximately 25 percent. Some of the Hybrid Honda Accord benefits identified include: „Ï Reduce the Greenhouse emissions by 30% under real-life driving conditions „Ï Reduce the potential removal of Carbon monoxide by reducing the amount of Greenhouse emissions tons from 86 tons for the Conventional vehicle to 64.5 tons for the Hybrid under real-life driving conditions „Ï Provide an opportunity to drive pure electric, zero emission mode (e.g. in residential or inner city areas) Some of the disadvantages of HEVs are: „Ï Weight: HEVs often contain more components than conventional cars and have a tendency to increase the weight of the vehicle. More weight means more energy required to propel the vehicle, reducing the potential energy benefits of HEVs. One of the factors that contribute to excess weight is the battery. „Ï Complexity: These vehicles are generally more complex in design compared to conventional drive train vehicles. „Ï Maintenance: This new technology not only needs a more specialized infrastructure and also an expensive maintenance system. „Ï Price: The HEVs' high-tech components are more expensive to produce especially at the introduction phase, where production volumes are small, and hence the market price of hybrids will be higher. Based on this life cycle analysis study, the following suggestions are made to reduce the impact of vehicular emissions: „« Manufacturers should influence the amount of ASR generated per vehicle through the materials they select to build their vehicles and the extent to which their vehicles can be dismantled. „« By specifying recycled stock in new automotive parts, manufacturers will improve market demand for some recycled materials, thereby supporting the recycling infrastructure.
