|Alternate technology||Biodiesel fuel||Biodiesel is renewable fuel made by combining organic oils with an alcohol. It produces lower emissions and can be used in diesel engines alone or blended with petrodiesel fuel.
|Vehicle emissions standards||Emission standards set limits on the amount of particulate and gaseous pollutants that vehicles can release into the environment. Different standards apply in different parts of the world.|
|Fuel & battery technology||Alternative fuels
||Alternative fuel sources are used as a way of reducing the operating cost of vehicles, reducing pollution from vehicle emissions, or both.
||A fuel cell is an electro chemical device that combines hydrogen and oxygen to produce water and in the process it produces electricity and heat. Fuel cells operate without combustion so they are virtually pollution free.
||Vehicles that include electric drive motors have many advantages over the traditional vehicle. Lower noise and gas emissions are among the major benefits. As well as: fewer moving parts, less maintenance requirements and increased reliability.
||A biodegradable and non-toxic diesel-equivalent, processed fuel derived from biological sources, it has significantly fewer emissions than petroleum-based diesel when burned.
