“…Currently the consequence-based approach has been adopted in Finland, Luxembourg, Spain and Austria [2,3,37,38] and proposed in Greece [38]. As far as the generic-distances approach, this has been established in Germany and Sweden [2,3,37,38], while the risk-based approach has been adopted in the UK [2,3,[37][38][39][40][41][42] and the Netherlands [2,3,37,38,43] and proposed in Belgium [44][45][46]. In France [47][48][49] and Italy [50], after the accident in Toulouse [51], the consequence-approach has been replaced by hybrid approaches combining the advantages of the risk and consequence-based approaches.…”
