One environmental benefit of natural gas over coal is that it produces fewer carbon dioxide emissions.

When burned for energy, natural gas produces significantly less carbon dioxide (CO2) compared to coal. This makes it a cleaner option in terms of greenhouse gas emissions, which is a key factor in efforts to reduce climate change. Additionally, natural gas combustion emits lower levels of pollutants like sulfur dioxide and particulate matter, which helps improve air quality. As a result, natural gas is often seen as a "bridge fuel" in the transition from coal to renewable energy sources.
