Bicycles provide environmental benefits over motor vehicles by not burning fossil fuels or producing harmful emissions, reducing air pollution. Commuting by bicycle can prevent between 0.7 and 1.9 tons of carbon dioxide emissions per year depending on the type of vehicle otherwise used. Motor vehicles are major sources of air pollution that increases health risks like respiratory illness and premature death. Using bicycles for transportation instead of driving can help address traffic, pollution, and public health issues while also providing individual health benefits and cost savings over automobile ownership and operation.
