Euroregions with more integrated structures seem to have a more general objective of promoting common interests through transfrontier co-operation. Transfrontier activities extend not only to socio-economic development and cultural co-operation, but also to other areas which are of general interest to frontier populations, such as social affairs, health care, education and training, waste management, nature conservation and landscape management, tourism and leisure, co-operation in the case of natural disasters and transport.

Euroregions also differ in the practice of transfrontier activities. Some of them are limited to exchanges of information, consultation and undertaking studies, others seem to have the capacity to manage and implement concrete projects.

It was not possible to ascertain from the information provided whether having a private law basis added to the Euroregion's capacity to act.
