How can alternative fuels affect transportation emissions?

The choice indicating that alternative fuels can help reduce overall transportation emissions is correct because alternative fuels, such as electricity, hydrogen, biofuels, and compressed natural gas, typically produce fewer greenhouse gases and pollutants compared to conventional fossil fuels. By utilizing these cleaner energy sources, vehicles can contribute to a significant decrease in carbon dioxide emissions and other harmful byproducts associated with traditional petrol or diesel engines.

Moreover, alternative fuels can also be produced through renewable processes, further minimizing their carbon footprint. For instance, electric vehicles charged with renewable energy sources such as wind or solar power can dramatically decrease the emissions commonly associated with fossil fuel-based transportation. This transition not only reduces the number of pollutants entering the atmosphere but also promotes sustainable practices within the transportation sector, aligning with global efforts to mitigate climate change.

Considering the other options, the statement regarding the increase in emissions is inaccurate, as alternative fuels are designed to be more environmentally friendly than their conventional counterparts. The claim that they have no impact on emissions overlooks the substantial benefits these fuels provide. Lastly, suggesting that alternative fuels are only viable for public transportation fails to acknowledge their applicability across various transportation modes, including personal vehicles, freight transport, and aviation, expanding their potential benefits beyond just public systems.
