Miami Beach – The US Conference of Mayors approved a resolution on Monday calling for 100 per cent renewable energy in US cities by 2035. The resolution was approved by leaders from more than 250 cities.

The resolution was introduced by the co-chairs of Mayors for 100% Clean Energy, an initiative led by the co-chairs of the Sierra Club’s renewable energy campaign and a small, bipartisan group of mayors, reported CityLab. The resolution supports a transition to wind, solar, geothermal and hydroelectric power by 2035. Not only does it reject energy derived from fossil fuels, it also specifically excludes nuclear, waste-to-energy and large-scale hydroelectric dams as qualifying as renewable energy.

“What better way to kick off Donald Trump’s energy week than with a message from our nation’s mayors that cities are ready for 100 per cent clean and renewable energy,” Sierra Club’s executive director Michael Brune said in a statement. “Cities don't need to wait for Washington, D.C. to act in order to move the ball forward on clean energy.”

According to Sierra Club, if cities belonging to the US Conference of Mayors were to transition to 100 per cent clean and renewable energy, this would reduce electric carbon emissions by more than that of the five worst carbon polluting US states combined. If the 100 per cent energy targets were achieved 10 years earlier by 2025, the total electric sector carbon pollution reductions would fill anywhere from 87 per cent to 110 per cent of the remaining reductions the US would need to achieve in order to meet the goals of the Paris Agreement.

To date, 36 cities across the US have pledged to transition to 100 per cent renewable energy.
