A project to close one of the world’s largest landfills, the 927-acre Bordo Poniente Landfill in Mexico City will stem the city’s largest source of greenhouse gas (GHG) emissions, while creating renewable energy and local jobs.
Developed in close collaboration with the Clinton Climate Initiative (CCI) Cities program and its partner the C40 Cities Climate Leadership Group (C40), the project represents a model for reducing GHG emissions through sustainable solid waste management than can be replicated around the world.
“I applaud the decision of the Mexican authorities to close the Bordo Poniente Landfill and reduce the city’s greenhouse gas emissions. I am glad the Clinton Climate Initiative was able to support the work necessary to make the closure possible,” said President Clinton. “Through the Clinton Climate Initiative, we are helping Mexico City convert millions of tons of garbage to new energy, and reduce greenhouse gas emissions by 2 million tons annually. This project will help the local economy and fight climate change.”
Solid waste in landfills is the third largest source of anthropogenic methane emissions – 23 times more potent as a greenhouse gas agent than CO2. Capturing methane from the Bordo Poniente landfill could reduce GHG emissions from Mexico City by 25 million tons of CO2 equivalent over the next 25 years – more than one quarter of the city’s total emissions. Globally, it represents one of the largest reductions of GHGs associated with solid waste management.
It is estimated that capturing methane from the Bordo Poniente Landfill could generate over 250 GWh or enough power for an estimated 35,000 homes in Mexico City during the first years of operation. Further economic benefits will come from the creation of both short and long-term local jobs for contractors, service providers and qualified labor in the construction, operation and maintenance of the landfill gas capture system.
The Bordo Poniente Landfill ceased receiving solid waste on December 19th, 2011. The same day, Mexico City Mayor Ebrard announced the international public tender for a developer to close the landfill in an environmentally-sound manner that optimizes the capture and utilization of methane gas to produce energy.
