Cities (or "sub-nationals," in international climate negotiations-speak) are at the vanguard of where real climate solutions are being implemented around the world. That will remain true in the years ahead, no matter how ambitious an agreement emerges from the COP21 climate talks in Paris this month--local and state governments will be shouldering much of the load of creative carbon emissions reduction, of energy efficiency improvements, and of access to renewable energy.

Billionaires unite to boost clean energy R&D, deal in the works to extend federal credits for solar and wind, US public opinion backs climate pact, and more news of the week in clean energy solutions.

The Urban Clean Energy Revolution report details the state of play of low-carbon cities and describes a rich array of best practices and examples of urban clean energy innovation and carbon reduction.

Darkness of the most desperate and terrifying kind descended on Paris in the November 13 attacks.  The world convenes now in the City of Light, with an ever more urgent and sober sense of the pressing need for global cooperation for peace and justice.

The international climate talks are a moment in time for forward-looking urban leaders to demonstrate the collective political will they have amassed for bold climate action, and to show how far they have already come in reducing carbon emissions.

The power of our NO fueled our run to the top of the hill... the power of our YES will lead us on over it and beyond.

Urban leaders are increasingly aligning their carbon reduction and clean energy agendas with other important community priorities—such as air quality, transportation, social equity, economic development, and climate change resilience. In doing so, they forge stronger and more diverse coalitions for climate action.  

Dedicated funding is a critical ingredient for urban clean energy action, but securing it is one of the most persistent challenges that local governments face today. Some leading communities are marching ahead on their own.
