(CNN) -- They are the world's cultural capitals, the nerve
centers of innovation and the engine rooms of economic growth, but could
cities also hold the key to cutting carbon emissions long-term?
A 2010 study from the World Bank found that the 50 largest cities and urban areas on the planet are now home to roughly 500 million people and spew out some 2.6 billion tons of greenhouse gasses every year.
As urban migration continues apace, these figures are only expected to rise in the short term. While this may initially lead to more pollutants being pumped into the earth's atmosphere, some experts believe it could work out better in the long term. They say that the ecological efficiencies cities can offer, aligned with their financial and political influence, could lead to the development of more effective ways to curb carbon emissions.
