using a car that travels farther on each gallon of gas

The correct answer is using a car powered by fuel cells.

Explanation:

A fuel cell utilizes the chemical energy of hydrogen or another fuel to effectively and cleanly generate electricity. If hydrogen is used as fuel, then water, heat, and electricity are the only products formed. Thus, using a car powered by fuel cells would be the most efficient action for the individuals to take in order to minimize emissions of greenhouse gases.  

The fuel cells are specific in terms of the array of their potential uses, as they can offer power for the systems as big as a utility power station, and as small as a computer. The fuel cells have an application in various things, which comprises material handling, transportation, emergency back-up power applications, and others.
