David Cameron is at the G20 Summit in Mexico promoting British companies, some of which manufacture low carbon technology, and saw the launch of a Green Growth Action Alliance.

Yesterday, the prime minister was at the G20 Business Summit (B20),which serves as a business advisory to G20 officials, where a Task Force on Green Growth attended by Mexican President Felipe Calderón urged heads of state to adopt policies that will simultaneously help to green and grow the economy in environmentally, economically and socially sustainable ways.

The Green Growth Task Force is asking G20 governments to initiate negotiations to achieve a sustainable energy trade agreement, create a robust price on carbon through coordinated international policies, end fossil fuel subsidies and to direct a portion of carbon price revenues to support innovation in sustainable technologies.

The call to end subsidies for fossil fuels was the subject of a 24-hour “Twitter storm” begun by Stephen Fry and aimed at the G20, on behalf of 350.org, which attracted over 100,000 tweets.

The Task Force also launched the Green Growth Action Alliance, whose honorary chairman is President Felipe Calderón. This new public-private partnership initiative of comprises 48 of the world’s largest energy companies, international financial and development institutions that aims to address the massive shortfall in financing the low carbon revolution globally.

Wind turbine manufacturer Vestas’ CEO Ditlev Engel explained that it will “boost public and private investment into green infrastructure. Each year, $1 trillion is needed to deliver the necessary infrastructure and to shift us onto a low carbon path.”
