What environmental benefit is gained by effective vapor recovery?

• A. Increased energy consumption
• B. Reduction in greenhouse gas emissions
• C. Higher costs for consumers
• D. More complex fuel processing

Answer: (B)

Capturing vapors that would otherwise escape during fueling and storage prevents volatile hydrocarbons from entering the atmosphere. Those vapors contribute to greenhouse gas effects and air pollution, so routing them back into the fuel system or burning them reduces the total emissions released. In short, effective vapor recovery lowers greenhouse gas emissions, which is why that choice is the true environmental benefit. The other options describe costs or complexities that aren’t environmental benefits.
