What does the term “CNG” stand for in the context of school buses?

Answer: A — Compressed Natural Gas

In the context of school buses, "CNG" stands for Compressed Natural Gas. This is a type of fossil fuel that is used as a cleaner alternative to traditional gasoline or diesel. CNG is stored under pressure, allowing for more efficient storage and transport, and it is often chosen for school buses due to its environmental benefits. Using CNG can significantly reduce emissions compared to conventional fuels, contributing to improved air quality—an important consideration for school buses that operate in residential areas and near schools. Additionally, CNG is generally more cost-effective than gasoline or diesel, making it a viable option for school districts looking to reduce operating costs while promoting sustainability. The other terms—such as Clean Natural Gas, Concentrated Natural Gas, and Converted Natural Gas—do not accurately define the commonly accepted terminology in the context of fuel types for vehicles like school buses, which focuses specifically on the compressed form of natural gas used for powering engines.
