What is the main reason for regulating vehicle emissions?

Regulating vehicle emissions is primarily aimed at protecting public health and the environment. Vehicle emissions include harmful pollutants such as carbon monoxide, nitrogen oxides, particulate matter, and volatile organic compounds. These substances can lead to serious health issues, including respiratory problems, cardiovascular diseases, and other adverse effects, particularly for vulnerable populations like children and the elderly. Additionally, emissions from vehicles contribute to environmental problems such as air pollution and climate change. By regulating these emissions, governments aim to reduce the overall health risks posed by air pollution and to protect natural ecosystems that can be disrupted by harmful emissions. This regulatory framework is essential for ensuring cleaner air quality and promoting a sustainable environment for current and future generations.
