Older vehicles often consume more fuel than newer ones. This means they release more pollutants per mile travelled. Older cars may have less efficient engines, poorer aerodynamics, or other factors that contribute to increased fuel consumption.
Older vehicles may have leaks or damaged components that release pollutants. As vehicles age, various parts and seals can deteriorate, leading to leaks or malfunctions that release harmful pollutants into the environment. These issues may include problems with the exhaust system, fuel system, or emission control devices.
Lack of proper maintenance can exacerbate environmental issues. Regular maintenance is crucial for ensuring that a vehicle's emissions systems function properly. Older cars that are not well-maintained may experience decreased efficiency and increased emissions due to worn-out or faulty components.
It's important to note that not all older cars are environmentally unfriendly. Some well-maintained older vehicles may have emission levels comparable to newer models. However, given the factors mentioned above, owners of older cars should take extra care to ensure that their vehicles are well-maintained and operated efficiently to minimise their environmental impact.
