The Environmental Performance Index (IDA) is an instrument for monitoring and controlling environmental management in port facilities. The IDA allows for quantifying and simplifying information to facilitate a better understanding of port environmental issues for the public and decision-makers. Given the diversity of indicators and the complexity of environmental issues in the port sector, the IDA is built using a multicriteria analysis methodology, considered the most appropriate to address and assess problems of environmental performance. The methodology applied is the Hierarchical Analysis Process (AHP).

The indicators that make up the IDA are chosen based on specialised technical literature, applicable environmental legislation and good practices observed in the global port sector. The IDA reviews projects across 38 indicators, which are then classified and weighted according to the degree of importance of each one. The following link provides the classification and distribution of indicator weights.
