Mayors, governors and subnational leaders call for greater action on fossil fuels from Heads of State at UN Summit

Read the letter from mayors, governors and subnational leaders.

Dear UN Heads of State,

As you meet for the General Assembly and Summit of the Future, we as leaders of States and Cities, urge you to transition your countries away from fossil fuels.

Make no mistake, the climate crisis is a fossil fuel crisis.

Fossil fuel use endangers the only planet we call home and our collective dependence on them contaminates the air we breathe, pollutes the water we drink, and threatens the health and livelihoods of communities from Lagos to Los Angeles.

It is gravely unjust that the architects of climate chaos continue to grow rich at the expense of the poor, who are the least responsible yet suffer the brunt of climate impacts.

The climate crisis is already here. Left unchecked, it will lock us into evermore extreme weather, crumbling economies, and human suffering on a scale never seen before.

The stakes could not be greater to protect the communities we serve and represent. The ray of hope we must cling to is that we already have the solutions at our fingertips. And the window to act, though ever-shrinking, is still open.

We cannot wait for under-developed and untested technologies that promise the world but are not yet viable. There is no time.

Right now, cities and states can and are making a decisive difference in this make-or-break decade by delivering effective and just climate action. Cities and states are responsible for the majority of global energy consumption and are using their powers to both cut demand for fossil fuels and supercharge clean and renewable energy production.

Mayors and governors are making huge strides in improving building energy efficiency - from homes to offices and schools - electrifying bus fleets, scaling up renewable energy, setting up clean energy utilities, and creating good green jobs to build cleaner, safer communities.

Through our actions we are sending clear signals to markets that fossil fuels are not welcome. We are reskilling workers for the green jobs of the future while protecting consumers from rising energy costs. And we are using the law to hold fossil fuel companies accountable for the damage they have caused.

We are working towards a vision of states, regions, and cities where a just transition away from fossil fuels has brought us lower energy bills, secure, sustainable, and fulfilling jobs, where human and environmental health is prioritised and no one is left behind.

This year, as elections around the globe threaten to scale back climate action, we stand together with the UN Secretary-General, António Guterres, in his call to rapidly reduce fossil fuel consumption.

To unlock this future we must banish fossil fuels to the past and curb their undue influence in the present. We cannot and will not be fooled by the smoke and mirror tricks played by those who want us to sleepwalk into our own extinction.

At a time when we need faster, fairer action, G20 nations continue to pour billions into fossil fuel subsidies. It's time to stop propping up these polluting industries and use these funds to scale up local and equitable climate action instead. This is the most effective way to cut emissions and will create a third more jobs than if we continue with business as usual.

No single actor can deliver this transition at the scale and pace needed. It's time to work with us to harness the power of cities and states to propel economic development, create healthier communities and safeguard our common future.

Urgent climate action is both possible and desired: 80% of people around the world support it. It's time to listen to them. It's time to up the pace. It's time to leave fossil fuels behind.

Yours in unity,
