Where environmental damage affects or is likely to affect several Member States, those Member States shall cooperate, including through the appropriate exchange of information, with a view to ensuring that preventive action and, where necessary, remedial action is taken in respect of any such environmental damage.

Where environmental damage has occurred, the Member State in whose territory the damage originates shall provide sufficient information to the potentially affected Member States.

Where a Member State identifies damage within its borders which has not been caused within them it may report the issue to the Commission and any other Member State concerned; it may make recommendations for the adoption of preventive or remedial measures and it may seek, in accordance with this Directive, to recover the costs it has incurred in relation to the adoption of preventive or remedial measures.
