Group Environmental KPI performance
With the KPI period extending to 2018 our Group environmental performance against a particularly robust and ambitious suite of KPIs has again delivered some strong results and we close out the KPI period by exceeding the target reduction of total carbon emissions (tCO2e) per million passenger km by over 19% and year-on-year 2017-18 by nearly 5%.
Water consumption reduction has also exceed the KPI period target by over 50% and reduced year-on-year by 4%. However, some challenges still remain with a year-on-year increase in site energy use and waste to landfill. As with last year, some of these changes are the result of improved reporting and accuracy of data but we will review this data at a site level and set improvement targets for the next period.
