Global investment in water supply infrastructure needs to increase from around $580 billion a year to more than $1,000 billion by 2025, according to the OECD. These figures dwarf those needed for roads and electricity, said Anthony Cox, head of the environment and economy integration division in the organisation’s environment directorate.
Addressing the World Water-Tech Investment Summit in London today, he said the private sector would be increasingly important in mobilising this finance. There is no shortage of private capital, he noted, with pension funds currently holding around $29 trillion. But less than 1% of this is invested in infrastructure and, of that, only a small percentage goes into green infrastructure, he said.
