Low-emission vehicles (LEVs) are designed to produce fewer harmful pollutants and greenhouse gases compared to traditional gasoline or diesel vehicles. These vehicles often include electric cars, hybrid vehicles, and those powered by alternative fuels like hydrogen or biofuels. By reducing emissions, LEVs contribute to cleaner air and help combat climate change. Governments around the world encourage the use of low-emission vehicles through incentives such as tax credits, rebates, and access to carpool lanes. Many cities are also implementing stricter emissions standards to promote the adoption of LEVs, aiming to improve public health and environmental sustainability.
