We would expect ESG matters to be reviewed in most, if not all, maintenance projects. However, this is the type of data that we expect to be collated and managed by the operational managers of the asset. It is good management practice to undertake preventative maintenance and maintenance will frequently include aspects that will have an ESG focus. Certified management systems such as ISOO 14001 encourage such inclusion of CSR maters in maintenance programmes.  Finally, good management practice, which we expect from our infrastructure assets, dictates that preventative maintenance is better for managing risks (including ESG risks) than reactive maintenance.
