Alliances for Climate Action

Connect, Collaborate and Change Our Future

What is this?

Local solutions to the global climate change challenge bring unusual coalitions together.

Alliances for Climate Action (ACA) is a global network of domestic multi-sector coalitions committed to supporting the delivery and enhancement of their countries’ climate goals. ACA connects cities, states, the private sector, investors, universities and civil society at the domestic level so that they can work with each other and with their national governments to drive climate action.

Why do we need this?

The Paris Agreement gave the world hope that humanity can effectively address the global climate change challenge. However, current commitments by national governments aren’t enough. There’s still a major gap between current pledges and what is needed to ensure a safer, more prosperous future for everyone.

Limiting the increase in global average temperature to 1.5°C is within reach – but only if we take strong action now across all levels of government and all segments of society. Leaders from business, academic institutions, regional and local governments and civil society have a vital role to play in delivering the Paris Agreement and ensuring a climate-safe future for all.

It’s all hands on deck now! These actors will lead the way by setting ambitious climate goals, by collaborating to deliver action on the ground and by working together to strengthen climate action at a national level.

What do the members do?

Take action individually

Collaborate with others at domestic level on joint climate actions

Encourage new actors to join

Champion higher ambition by engaging national goverments

Build public support for climate action domestically and internationally

Vietnam Coalition for Climate Action

Over twenty member organizations across Vietnam have come together to support climate resilience and a clean energy economy. Leaders from the private sector, universities, communities and civil society established the Vietnam Coalition for Climate Action to accelerate low-carbon development powered by renewable energy. Locally driven climate action is imperative in a country that is leading the world in carbon emissions growth. Whether it is sea level rise in the Mekong Delta, flooding on the central coast, or storms and droughts that are longer and more frequent, Vietnam is one of the most vulnerable countries to climate change. At the same time, renewable energy offers much potential to meet Vietnam's growing energy demands. Vietnam Coalition for Climate Action is dedicated to delivering on Vietnam’s national climate targets (or Nationally Determined Contributions (NDCs)), laying the groundwork for a strengthened NDC and a livable future for Vietnam and for the world.

Data and transparency are vital to this transition, with disclosure of environmental risk and impacts being the crucial first step for action. CDP holds the richest global dataset of self-reported environmental data from companies and cities around the world, and we are seeing unprecedented action. The transformation of the global economy is already underway. Now is the time to urgently accelerate this shift to meet the goals of the historic Paris Agreement.”
- Paul Simpson, CEO, CDP
