European Motorway Concessions Operators Cluster

The Standard Ethics European Motorway Concessions Operators Cluster was launched on 24th of April 2026.  It will be published at end 2026.

Purpose

The purpose of the Standard Ethics European Motorway Concessions Operators Cluster is to provide an overview of Sustainability within a sample of leading European motorway operators and monitor their progress in aligning with the international guidelines established by the UN, OECD and EU. The selection of the Cluster constituents is based on two specific sectoral indicators: i) the length (in kilometres) of the managed network in Europe, and ii) the average annual level of saturation of the managed network, as defined by the AADT indicator.

Each Standard Ethics’ Cluster is public and operates on a full disclosure basis: the methodology and selection criteria are publicly available and may therefore be freely used as benchmarks by decision-makers and stakeholders. Standard Ethics’ Clusters (formerly known as Indexes or Benchmarks) have been applying the same methodology since 2004 and are self-financed. Standard Ethics’ work focuses on sustainability ratings, and its clusters are not subject to commercial activity or used as financial products.

Constituents

The Cluster’s constituents are 30 of Europe’s largest Motorway Concessions Operators.

The weights of the individual constituents are derived from the solicited or unsolicited Corporate Standard Ethics Rating (SER) assigned to each company.

Rebalancing and Review

If the Agency intends to track the Cluster’s performance, as it has done in the past, it will determine the weighting of each component based on the Standard Ethics Rating and rebalance the Cluster on a monthly basis.

The Cluster is reviewed every six months, at the end of the first and third quarter.

Rating actions will be recorded only on the dates when the review is scheduled to take place.
