Bridging global infrastructure gaps
McKinsey Global Institute
The world today invests some $2.5 trillion a year on transportation, power, water, and telecommunications systems. Yet it’s not enough—and needs are only growing steeper. In a follow-up to its comprehensive 2013 report Infrastructure productivity: How to save $1 trillion a year, the McKinsey Global Institute finds that the world needs to invest an average of $3.3 trillion annually just to support currently expected rates of growth (exhibit). Emerging economies will account for some 60 percent of that need.
