According to Standard and Poor's the value of global infrastructure deals in 2006 was $145 billion, a 180% increase from 2000.
As I have blogged previously, in a 2007 report, Booz Allen Hamilton estimated the global investment in infrastructure needed for water and wastewater, power, roads/highways and rail, and ports and airports between 2005 and 2030 at about US$ 41 trillion. It broke the infrastructure spending down by sector
- Water and wastewater $22.6 trillion
- Power $9.0 trillion
- Road and rail $7.8 trillion
- Airports/seaports $1.6 trillion
- Middle East $0.9 trillion
- Africa $1.1 trillion
- US/Canada $6.5 trillion
- South America/Latin America $7.4 trillion
- Europe $9.1 trillion
- Asia/Oceania $15.8 trillion
In a 2009 report CIBC World Markets quotes estimates of up to $35 trillion in public works spending over 2010-2030. Geographically, the spending is broken down as
- North America $180 billion/year
- Europe $205 billion/year
- Asia $400 billion/year
- Africa $10 billion/year
Since then, a report by Credit Suisse Group AG referenced predictions by the Organization for Economic Co-operation and Development (OECD) that total new spending over the next 20 years could be as high as to $71 trillion.
But according to CG/LA Infrastructure, unless the world’s leading economies change the way they currently fund infrastructure development, they are more likely to invest about $24 trillion over the next 20 years.
In 2010 the World Economic Forum initiated the Positive Infrastructure Report (PIR) with the objective of facilitating a dialogue between businesses, policy-makers and civil society to ensure that the massive fiscal spending on infrastructure generates employment to restart the global economy and creates infrastructure that fosters long-term economic competitiveness and are environmentally and
socially sustainable. The PIR report assumed that the world is facing a global infrastructure deficit of US$2 trillion per year over the next 20 years based on the projections for future infrastructural development from the study by Booz Allen Hamilton.
