Vehicle emissions refer to the pollutants released into the atmosphere from vehicles, primarily from the combustion of fossil fuels. These emissions include harmful substances such as carbon monoxide, nitrogen oxides, and particulate matter, which contribute to air quality degradation and pose health risks to humans and wildlife. Reducing vehicle emissions is crucial for combating climate change and improving public health. Efforts to mitigate vehicle emissions include the development of cleaner technologies, such as electric vehicles and hybrid systems, as well as stricter regulations on fuel standards. Governments and organizations worldwide are promoting initiatives to encourage the use of public transportation and alternative fuels, aiming to create a more sustainable future.
