Facts and Figures

Climate change could cost the world at least 5% in GDP each year…and up to 20%

  • The Stern Review in 2006 concluded that by 2050 extreme weather could reduce global GDP by 1% and that, unabated, climate change could cost the world at least 5% in GDP each year. If even more dramatic predictions come to pass, the cost could rise to more than 20% of GDP.
  • An estimated 40% of development investments are currently at risk, according to analyses by the Organisation for Economic Co-operation and Development (OECD). These analyses indicate that while many development efforts contribute to reducing vulnerability to climate variability and change, climate risks are seldom explicitly factored into development projects and programmes.
