Alliances for Climate Action
Together we will build a net zero carbon future.
What is ACA?
As the climate crisis deepens, we find ourselves in a race against time. We need to build inclusive societies that provide well being for all, powered by renewable energy and sustained by nature. And we need to do this at an unprecedented pace to avoid catastrophic climate impacts. The transition to a decarbonized economy has begun, but it is not happening at the speed and scale needed to keep global average temperatures from rising above 1.5°C—beyond which we will experience increasingly devastating impacts on our economies, livelihoods, health, ecosystems, and physical infrastructure.
To realize the transformation to a zero carbon future, we need everyone - across all walks of life and in every country around the world - to advance climate solutions together.
Alliances for Climate Action (ACA) is a network of national alliances dedicated to driving ambitious climate action, increasing public support for addressing the climate crisis, and engaging national governments to decarbonize faster. These national alliances are unique because they include a diversity of voices representing leaders from nearly every sector of society—state, local, and regional governments; companies and investors; academic and cultural institutions; tribal organizations and faith communities; healthcare institutions, and civil society.
There is no question that national governments are needed to steer the transition to decarbonized economies in their respective countries, but the groups that make up these alliances are equally critical. They provide jobs, drive innovation, and collaborate to develop creative and inclusive solutions to the climate crisis.
Everyone must act and, together, we are stronger.
