The party in charge is the Environmental Monitor. 
The environmental, territorial, and social monitoring activities for the pre-construction (ante operam), construction, and operational (post operam) phases of the Bridge and its road and rail links are carried out by the Environmental Monitor, selected by international tender. The Environmental Monitor is the Temporary Grouping of Companies led by Edison Next Environment Srl. The monitoring activities serve as a critical oversight tool for assessing territorial, environmental, and socioeconomic impacts. They will enable Stretto di Messina to supervise the General Contractor and continuously evaluate the effectiveness of planned and implemented mitigation measures in real time.
