They are usually associated with high costs and harmful to the environment – we are talking about car repairs. This is especially the case when car parts have to be replaced. A study from Britain now shows that considerably more CO₂ emissions are made when installing new spare parts that are used instead of used spare parts.
With the help of the example of the door of a Volkswagen ID.3, the Allianz accident and traffic researchers calculated how environmentally harmful which variant of a repair is. The least CO₂ emissions arise when the broken door is not replaced, but is made again.
Exchange of car components is harmful to the environment
If the repair is no longer possible, the installation of a used car door causes almost a fifth higher CO₂ emissions compared to repairing the old door. If you install used spare parts in a car, most emissions arise when painting and harden afterwards.
If the workshop has to use a whole new door, the emissions of the climate – striky greenhouse gas increase by 157 percent – ie more than two and a half times compared to the part used. In the case of new parts, energy-intensive steel production deteriorates CO₂ balance.
Researchers analyze 33 repair steps
The study is based on complex calculations: the authors looked at 33 steps when repairing a car car and calculated the CO₂ load of each of these steps. In the beginning, the drive by dragging the towing car on the scene of the accident, at the end of the reserve section. The estimated CO₂ emissions of the package during transport were also included.
