Cars typically emit carbon dioxide (CO2) as part of their exhaust gases. When a combustion engine burns fuel, it releases various byproducts, including carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons, and particulate matter. While carbon dioxide is the dominant greenhouse gas produced from vehicle emissions, it is significant in contributing to climate change. Modern vehicles aim to minimize these harmful emissions, and advancements in technology, such as catalytic converters and electric vehicles, are designed to reduce environmental impacts.
