Water consumption across our global occupied estate increased by 1.6%, driven predominately by improvements in data quality driven by more invoiced data. (Reported consumption increased in Asia and the US with increases of 19.5% and 6.3% respectively. There was a decrease of 16.8% in UK/EU/Africa. Water audits were completed in six of our larger serviced offices in Asia during 2018, although opportunities to reduce consumption at these sites were considered low. Opportunities to reduce consumption in our larger UK and US offices offer more potential where we exercise greater control on facility-related investments.
Water consumption from our investment portfolio, managed by M&G Real Estate, increased 2%. This is driven by a mix of portfolio changes (acquisition and divestment), changes to operational control of the assets and enhanced reporting.
