Only a sustained and dramatic shift to infrastructure and industrial practices using low-carbon technology can save the world and its economy from devastating global warming, according to a Davos-commissioned alliance led by the former Mexican President, Felipe Calderon, in the most dramatic call so far to fight climate change on business grounds.

This includes everything from power generation, transport, and buildings to industry, forestry, water and agriculture, according to the Green Growth Action Alliance, created at last year’s Davos meeting in Mexico.

The extra spending amounts to roughly $700bn a year until 2030 and would provide a much-needed economic stimulus as well as reduce the costs associated with global warming further down the line, said Mr Calderon, who leads the alliance.
