Vehicle emissions can affect the environment in several ways. Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. (See Reference 2, page 13) Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals. (See Reference 5) Nitrogen oxides and sulfur oxides are major contributors to acid rain, which changes the pH of waterways and soils and can harm the organisms that rely on these resources.

The primary greenhouse gas responsible for global warming is carbon dioxide. The U.S. is responsible for 19.91% of the carbon dioxide emissions worldwide.

To arrest man-made global warming, the world needs to stop the atmospheric stock of greenhouse gases from increasing. This requires emissions to be reduced until they balance with the rate of natural removal from the atmosphere.

THE WORLD is changing; opinions are changing, economies are changing, values are changing and the environment is changing.The environment is arguably the most important thing that is drastically transforming. This global warming, as we know it, is being caused by the burning of fossil fuels — emitting CO2 and other greenhouse gasses into the atmosphere. These fuels are burned in cars, in our homes and first and foremost in power generating stations. One of the primary fuels burned in power stations is coal and lets get one thing straight from the start: burning coal is not clean.
