What is an environmental concern associated with propane use?

The correct choice highlights greenhouse gas emissions as a significant environmental concern associated with propane use. While propane is often considered a cleaner-burning fossil fuel compared to others like coal or oil, it still releases carbon dioxide (CO2) when combusted. CO2 is a greenhouse gas that contributes to climate change by trapping heat in the atmosphere. The burning of propane can also produce other greenhouse gases like methane if not completely combusted, further exacerbating its environmental impact.

In addition to CO2, other concerns may arise with propane, such as the potential release of volatile organic compounds (VOCs) during extraction and transportation, but the primary concern remains its contribution to global warming through greenhouse gas emissions. Thus, understanding propane’s impact as a fossil fuel is crucial in evaluating its environmental footprint and making informed decisions on energy use and policy.
