What makes CNG a more environmentally friendly option compared to gasoline?

• A. Higher carbon content
• B. Lower sulfur compounds
• C. Lower greenhouse gas emissions
• D. Increased combustible materials

Answer: (C)

Choosing compressed natural gas (CNG) as a fuel option is considered more environmentally friendly primarily because it results in lower greenhouse gas emissions compared to gasoline. When combusted, CNG produces significantly fewer carbon dioxide (CO2) emissions per unit of energy generated. This reduction in CO2 output is crucial in combating climate change, as greenhouse gases trap heat in the atmosphere. In addition to lower CO2 emissions, CNG generally produces fewer pollutants such as nitrogen oxides (NOx) and particulate matter, which contribute to air quality issues. The overall cleaner combustion process associated with CNG helps in reducing the environmental impacts typically associated with traditional gasoline engines. While other options may touch upon aspects of fuel properties, they do not directly contribute to the primary advantage of CNG in terms of its impact on greenhouse gas emissions. So, the choice reflecting CNG's advantage in producing lower greenhouse gas emissions aligns well with its classification as a more sustainable fuel alternative.
