Cities emit 60 percent more carbon than expected, says study
Metro areas are outsourcing pollution. But a new analysis is already inspiring new progress in cutting emissions Cities may have been overlooking the true extend of urban pollution, according to a new research paper that shows metro areas are responsible for 60 percent more carbon emissions than previously expected.
But while that?s not great news for those working to limit the impact of climate change, the new information has already helped some local leaders reshape environmental policy to achieve better results.
In short, pollution is being outsourced. The study, Consumption-based GHG emissions of C40 cities, recalculated urban carbon emissions based on both production and consumption. Funded by C40, an international coalition of cities seeking to fight climate change and promote better environmental policy, the analysis found the carbon footprint of big cities was larger than previously estimated, when all the products and services a city uses are included. Current conventional wisdom estimates cities emit 70 percent of the world?s carbon dioxide, according to National Geographic. But that figure undercounts all the carbon emissions required to sustain the economic activity of cities. The report author Michael Doust included all services, agricultural production, and manufacturing emissions that create the goods used by city dwellers.
