A green vehicle is a Vehicle that is considered to be "environmentally friendly". This is accomplished by having a low There was an error working with the wiki: Code[5]. Part of the total energy cost can be cut by choosing smaller, lighter vehicles that use less energy to produce (Production phase).

During the life of the car (operational phase), large reductions in energy costs can be made through several measures:

The most significant is by using There was an error working with the wiki: Code[6]:

An efficient engine that reduces the vehicle's consumption of Petroleum (i.e. There was an error working with the wiki: Code[7]), or, preferably, that uses Renewable energy sources throughout its working life (i.e. Battery electric vehicle).

Using Biofuels instead of petroleum fuels.

Proper maintenance of a vehicle such as engine tune-ups, oil changes, and maintaining proper tire pressure can also help. Removing unnecessary items from a vehicle reduces weight and improves fuel economy as well.


Examples of vehicles with reduced petroleum consumption include Electric cars, Hybrid cars and There was an error working with the wiki: Code[8]s. There was an error working with the wiki: Code[9] races are held on a regular basis in order to promote green vehicles and other "There was an error working with the wiki: Code[10]". These sleek driver-only vehicles can travel long distances at highway speeds using only the electricity generated instantaneously from the sun.

A conventional vehicle can become a greener vehicle of a sort by mixing in renewable fuels. Typical There was an error working with the wiki: Code[1]. There are some places that have built cars that run strictly on ethanol, but another option is a There was an error working with the wiki: Code[11], which allows a varying mixture (often up to 85%, sometimes up to 100%{{cite web

There was an error working with the wiki: Code[2]-powered vehicles can often transition completely to There was an error working with the wiki: Code[12], though the fuel is a very strong solvent, which can occasionally damage rubber seals in vehicles built before 1994. More commonly, however, biodiesel causes problems simply because it removes all of the built-up residue in an engine, clogging filters, unless care is taken when switching from dirty fossil-fuel derived diesel to bio-diesel.

European Union

The European Union is promoting the marketing of greener cars via a combination of binding and non-binding measures.

Environmental Protection Agency

The US Environmental Protection Agency is promoting the marketing of greener cars via the There was an error working with the wiki: Code[13] program. The SmartWay and SmartWay Elite designation mean that a vehicle is a better environmental performer relative to other vehicles. This US EPA designation is arrived at by taking into account a vehicle's Air Pollution Score and Greenhouse Gas Score. Higher Air Pollution Scores indicate vehicles that emit lower amounts of pollutants that cause smog relative to other vehicles. Higher Greenhouse Gas Scores indicate vehicles that emit lower amounts of carbon dioxide and have improved fuel economy relative to other vehicles.

To earn the SmartWay designation, a vehicle must earn at least a 6 on the Air Pollution Score and at least a 6 on the Greenhouse Gas Score, but have a combined score of at least 13. SmartWay Elite is given to those vehicles that score 9 or better on both the Greenhouse Gas and Air Pollution Scores.

Green Vehicle Benefits


Vehicle emissions contribute to the increasing concentration of gases that are leading to climate change. In order of significance, the principal greenhouse gases associated with road transport are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Road transport is the third largest source of UK greenhouse gases and accounts for over 20% of total emissions. Of the total greenhouse gas emissions from transport, over 85% are due to CO2 emissions from road vehicles. The transport sector is the fastest growing source of greenhouse gases.

Road transport also remains the main source of many local emissions including benzene, 1,3-butadiene, carbon monoxide (CO), nitrogen oxides (NOx) and particulates (PMs). Within urban areas, the percentage of contributions due to road transport is particularly high - in London road transport contributes almost 80% of particulate emissions.


Vehicle pollutants have been linked to human ill health including the incidence of respiratory and cardiopulmonary disease and lung cancer. In 1998, a report entitled "The Medical Effects of Air Pollutants" estimated that up to 24,000 people die prematurely each year in the UK as a direct result of air pollution. According to the There was an error working with the wiki: Code[14], up to 13,000 deaths per year among children (aged 0-4 years) across Europe are directly attributable to outdoor pollution. The organisation estimates that if pollution levels were returned to within EU limits, more than 5,000 of these lives could be saved each year.

Currently there is no EU law which limits the amount of carbon dioxide produced by cars. However the European Commission reached a voluntary agreement with the There was an error working with the wiki: Code[15] to reduce the average CO2 emissions to 140g/km by 2008 for all new cars sold in the EU with a possible second target of 120g/km by 2012.


Many fleet operators of hybrid vehicles have reduced brake maintenance costs, through less use of brake parts due to regenerative braking. The labour costs saved from this maintenance is also significant. As much as 65% of brake related costs have been saved, according to a report by the There was an error working with the wiki: Code[16].

Hybrid taxi fleet operators in New York have also reported that reduced fuel consumption saves them thousands of dollars per year, as well as reduced maintenance costs.

}} suggests that the extra energy cost of manufacture, shipping, disposal, and the short lives of some of these types of vehicle (particularly gas-electric hybrids) outweighs any energy savings made by their using less petroleum during their useful lifespan. These claims are under dispute. The latest version of the report incorporates more data through 2006 and revises much of the conclusions.
