Combustion reactions typically involve the burning of fuels in the presence of oxygen, resulting in the production of various combustion products. One of the primary byproducts of combustion is carbon dioxide, which contributes to the greenhouse effect and global warming. Additionally, combustion can release other harmful gases such as carbon monoxide, nitrogen oxides, sulfur dioxide, and particulate matter into the atmosphere. These substances can lead to air pollution, have adverse health effects on living organisms, and contribute to environmental issues like acid rain and smog formation.

Recognizing these environmental impacts is crucial, as they highlight the need for cleaner alternative energy sources and reinforces the importance of implementing regulations to manage emissions from combustion processes.
