It does not suffice to create ambitious international institutions for environmental protection – these also need to be implemented in practice. How can policy ensure, through appropriate institutional design, that the implementation of global agreements is monitored adequately and – if necessary – non-compliance sanctioned?

ing information on the status of implementation. • Appropriate procedures for assessing reports and

other findings and for engaging in initial debate on international responses to implementational deficits.
