What environmental benefit does using CNG offer compared to traditional fuels?

Answer: B — Lower carbon dioxide emissions

Using compressed natural gas (CNG) offers a significant environmental advantage due to its lower carbon dioxide emissions when compared to traditional fossil fuels, such as gasoline and diesel. CNG is primarily composed of methane, which burns more cleanly than other fuels, resulting in reduced production of harmful pollutants. This cleaner combustion means that vehicles powered by CNG emit less carbon dioxide, a major greenhouse gas that contributes to climate change. By choosing CNG, drivers can help reduce their carbon footprint and promote a cleaner atmosphere, aligning with broader environmental goals aimed at mitigating global warming and improving air quality. The incorrect choices highlight aspects that do not reflect the cleaner nature of CNG. For example, higher emissions of sulfur oxides and higher greenhouse gas emissions contradict the established benefits of CNG, while suggesting there is no difference in emissions ignores the clear advantages CNG has over traditional fuels regarding emissions.
