Auto Emissions and Clean Air:Motor Vehicles and Global Warming
Policies AddressingCar Emissions and Air Pollution
1) adopt fuel-saving mechanisms in new vehicles
2) make cars lighter to save fuel
3) adjust pricing to make smaller cars cheaper, gas guzzlers more expensive

Hydrogen Fuel Cell Technology (HFC Technology)
What is it?A cell that puts hydrogen through an electrochemical process that ultimately creates energy and electricity for the car to use.
The process used in this technology is similar to that in a battery, however would not need replaced and would never run out like batteries.
The Positives to HFC Technology
Emissions from hydrogen fuel cells, unlike engines we have today, is simply water. Which is not harmful to the environment and could even be reused.
Can be extracted from other energy sources such as coal. The coal is abundant and therefore extracting hydrogen from it could meet the demands that are needed to replace gasoline used for current cars.
It is important to note, the conversion efficiency, or how well it converts fuel into energy, is roughly 50% which is substantially higher than what one expects out of current cars and engines today
The Negatives of HFC Technology
Two main problems, very similar but not the same.
First: If somewhere along the lines fossil fuels are used in the energy conversion process for HFCs or even in the whole process to produce the hydrogen or something to carry it in, ultimately the emissions from cars won’t be completely eliminated only reduced, and maybe not reduced by much.
Secondly: If fuels we have today are used to produce the hydrogen or the technology for it then the molecules that contribute to environmental problems like Carbon Dioxide, will still be created by molecules used to produce hydrogen still escaping into the atmosphere.
