The car whose production of carbon dioxide is least will have the most percentage reduction in the amount of hydrocarbon emission.
<h3>What is a hydrocarbon?</h3>
A hydrocarbon is a compound which is composed of hydrogen and carbon only.
Hydrocarbons are important as they are commonly used as fuels for many vehicles.
The products of the combustion of hydrocarbons are carbondiodioxide, water and heat.
Because of the effect of carbon dioxide as a greenhouse gas, many vehicles are switching to fuels with less hydrocarbon emissions.
Therefore, a car whose production of carbon dioxide is least will have the most percentage reduction in the amount of hydrocarbon emission.
