Why are short journeys performed with a cold engine especially damaging to the environment?

Short journeys with a cold engine are particularly harmful for two main reasons. Firstly, more fuel is consumed because a cold engine operates less efficiently, leading to higher emissions and more pollutants being released into the atmosphere. Secondly, the level of material wear is higher since the engine and its components, such as oil and other fluids, do not reach optimal operating temperatures. This inefficiency not only contributes to environmental damage but also results in more frequent maintenance and repairs, reinforcing the need for proper vehicle usage as outlined in German traffic regulations. Understanding these impacts is essential for promoting environmentally friendly driving practices.
