Why is the aid amount based on the extra environmental investment costs and not the full investment costs?
The aid amount is based on the extra investment costs necessary to achieve the level of environmental protection compared to, for example, an installation fulfilling the mandatory standard or a method of production that is less environmentally friendly in the absence of standards. If this were not the case, any investment that increases the level of environmental protection would be eligible for environmental aid, even if the investment is not more costly than the alternative.
