All about Global Warming
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate forever.
While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years.

Greenhouse Gas emission
In the U.S., our energy-related activities account for three-quarters of our human-generated greenhouse gas emissions, mostly in the form of carbon dioxide emissions from burning fossil fuels. More than half the energy-related emissions come from large stationary sources such as power plants, while about a third comes from transportation. Industrial processes (such as the production of cement, steel, and aluminum), agriculture, forestry, other land use, and waste management are also important sources of greenhouse gas emissions in the United States.
For a better understanding of where greenhouse gas emissions come from, governments at the federal, state and local levels prepare emissions inventories, which track emissions from various parts of the economy such as transportation, electricity production, industry, agriculture, forestry, and other sectors. EPA publishes the official national inventory of US greenhouse gas emissions, and the latest greenhouse gas inventory shows that in 2005 the U.S. emitted over 7.2 billon metric tons of greenhouse gases (a million metric tons of CO2 equivalents (MMTCO2e) is roughly equal to the annual GHG emissions of an average U.S. power plant.)

On the Road
The burning of fuels releases carbon dioxide (CO2) into the atmosphere and contributes to climate change, but these emissions can be reduced by improving your car’s fuel efficiency. You can take the following actions to reduce your greenhouse gas emissions, reduce the nation's dependence on oil and save money. For more information, there are also a number of transportation tools available to estimate emissions from transportation and the amount of greenhouse gas emissions that can be reduced through specific activities.

1.Buy smart
Before buying a new or used vehicle (or even before renting a vehicle), check out EPA's Green Vehicle Guide and the jointly-run EPA/DOE Fuel Economy Guide. These resources provide information about the emissions and fuel economy performance of different vehicles. The Green Vehicle Guide provides detailed information on emissions (including Air Pollution and Greenhouse Gas scores for each model) and the Fuel Economy Guide focuses on fuel efficiency (including side-by-side fuel economy comparisons and a customized fuel cost calculator). These Web sites are designed to help you choose the cleanest, most fuel-efficient vehicle that meets your needs. There are a wide range of cleaner, more fuel-efficient vehicles available on the market today that produce fewer greenhouse gas emissions.
2.Drive smart
Many factors affect the fuel economy of your car. To improve fuel economy and reduce greenhouse gas emissions, go easy on the brakes and gas pedal, avoid hard accelerations, reduce time spent idling and unload unnecessary items in your trunk to reduce weight. If you have a removable roof rack and you are not using it, take it off to improve your fuel economy by as much as 5 percent. Use overdrive and cruise control on your car if you have those features. For more tips to improve your gas mileage, visit the Fuel Economy Guide.
3.Tune your ride
A well-maintained car is more fuel-efficient, produces fewer greenhouse gas emissions, is more reliable, and is safer! Keep your car well tuned, follow the manufacturer’s maintenance schedule, and use the recommended grade of motor oil. Also check and replace your vehicle’s air filter regularly. For more details, including potential savings from these actions, visit the Fuel Economy Guide Web site.
4.Check your tires
Check your tire pressure regularly. Under-inflation increases tire wear, reduces your fuel economy by up to 3 percent and leads to higher greenhouse gas emissions and releases of air pollutants. If you don’t know the correct tire pressure for your vehicle, you can find it listed on the door to the glove compartment or on the driver's-side door pillar. More details on the Fuel Economy Guide Web site.
5.Give your car a break
Use public transportation , carpool or walk or bike whenever possible to avoid using your car. Leaving your car at home just two days a week will reduce greenhouse gas emissions by an average of 1,600 pounds per year. Whenever possible, combine activities and errands into one trip. For daily commuting, consider options like telecommuting (working from home via phone or over the Internet) that can reduce the stress of commuting, reduce greenhouse gas emissions, and save you money.
6.Use Renewable Fuels
Both E85 and biodiesel are renewable fuels that can reduce greenhouse gas emissions from your vehicle. E85 is a fuel blend containing 85% ethanol that can be used in certain vehicles called Flex Fuel Vehicles (FFVs). FFVs can be fueled with E85 or with traditional gasoline. There are approximately 6 million FFVs on the road today. To find out if you own one of them, check the inside of your car's fuel filler door for an identification sticker or consult your owner’s manual. If you own a diesel vehicle, consider filling up with a biodiesel blend such as B5, a fuel blend containing 5% biodiesel. Biodiesel is a renewable fuel made from agricultural resources such as vegetable oils. The Department of Energy’s Alternative Fueling Station Locator can help you locate both E85 and biodiesel fuel stations in your area.

Here you will find information on carbon dioxide (CO2) and other greenhouse gas (GHG) emissions from transportation sources, including information about transportation’s contribution to total GHG emissions, relevant EPA regulations, and what you can do to reduce your transportation emissions.
Transportation sources accounted for approximately 29 percent of total U.S. GHG emissions in 2006. Transportation is the fastest-growing source of U.S. GHGs, accounting for 47 percent of the net increase in total U.S. emissions since 1990. Transportation is also the largest end-use source of CO2, which is the most prevalent greenhouse gas. These estimates of transportation GHGs do not include emissions from additional lifecycle processes, such as the extraction and refining of fuel and the manufacture of vehicles, which are also a significant source of domestic and international GHG emissions.
