The G20 summit took place at Pittsburgh's David L. Lawrence Convention Center on September 24–25, 2009. Announced shortly after the April 2009 G-20 London summit, U.S. President Barack Obama volunteered to host this summit, initially planning to hold it in New York City and coordinating it with the opening of the United Nations General Assembly. However, due to coordination issues, on May 28, 2009, the Obama Administration announced a change of venue to Pittsburgh in order to highlight the city's economic recovery following the collapse of its manufacturing sector in the latter half of the 20th century. In response to the Global credit crisis, a G20 summit in one year was proposed shortly after the London summit in April 2009. The second G20 2009 summit will hopefully evaluate the measures taken in April 2009 in London and implement new policies which will stimulate the global economy.
Amongst the issues to be discussed is a proposal to radically reform the International Monetary Fund. French President Nicolas Sarkozy also suggested that there would be an evaluation of measures already taken.
The primary venue of the summit will be the David L. Lawrence Convention Center, which was at one point the largest LEED certified building in the world. A working dinner for world leaders will also be held at the Phipps Conservatory & Botanical Gardens, chosen to highlight its environmentally friendly features including an earth-sheltered welcome center and a Tropical Forest Conservatory described as the world’s most energy efficient. Other venues to be used around the city include The Andy Warhol Museum, the Pittsburgh High School for the Creative and Performing Arts and Rosemont, the working farm of Teresa Heinz Kerry.
Direct Energy Business, a retail energy supplier headquartered in Pittsburgh, will be greening the electricity usage of the city of Pittsburgh for both days of the G-20 Summit by securing Renewable Energy Certificates, or RECs
