Climate change is already affecting everyone on the planet. Vulnerable communities are often hit hardest, though they did the least to cause the problem. We must adapt.

Climate adaptation can bring major benefits to people and the economy. The right investments can make communities safer, stronger, and more equitable. Yet, action has not matched the scale of the crisis. While the world has made progress on raising global ambition on adaptation, far more must be done. We need bold and urgent action to accelerate adaptation.

The Adaptation Action Coalition (AAC) aims to accelerate adaptation globally. This state-led initiative of 40 member countries (and counting) is driving adaptation action to achieve a climate resilient world by 2030. Together, AAC members will foster even greater political ambition on adaptation, turning high-level commitments into targeted, tangible and practical action.

By accelerating global action on adaptation, the AAC will help people, economies and the planet become more resilient and equitable.

Vision, Mission and Purpose

The Adaptation Action Coalition will deliver sector-specific, action-orientated workstreams, focused initially on health, water, locally led action, disaster risk reduction and infrastructure in 2021. The Adaptation Action Coalition will build upon the 2019 UN Climate Action Summit ‘Call for Action on Adaptation and Resilience.’ Where the Call for Action signaled intent and ambition, the Adaptation Action Coalition will drive action through targeted sectoral workstreams and events.

  • Vision: The AAC will build a vision for a climate resilient future that puts adaptation at the center of decision-making and takes immediate action now to protect people, economies and the environment.
  • Mission: The AAC’s primary aim is to accelerate global action on adaptation to achieve a climate resilient world by 2030.
  • Purpose: The AAC will bring together countries of the world to advance progress on the Call for Action on Adaptation and Resilience.

To deliver on this mandate, the AAC’s workstreams will:

  • Demonstrate real-world action being taken to respond to climate risks
  • Build the evidence base on good adaptation practices
  • Support the integration of climate risk into sectoral and national plans
  • Highlight equity, inclusion and the Principles for Locally Led Adaptation


The Coalition was founded by the UK in partnership with Egypt, Bangladesh, Malawi, the Netherlands, Saint Lucia and the United Nations Development Programme (UNDP). The founding members, plus Colombia, Fiji, Ghana, Japan, and the USA make up the Steering Committee.

The coalition is open to all UN member states, as well as the European Union, who have signed the Call to Action.

Partnerships and Workstreams

The Adaptation Action Coalition will deliver sector-specific, action-orientated workstreams. Each workstream is headed by at least one partner organization.

The initial workstreams for 2021 include:


Leads: World Health Organization

Countries: Fiji and Spain

The workstream will encourage and support countries to commit to building health resilience, initially through developing health vulnerability and adaptation assessments, and national health adaptation plans, and proposals for submission to the Green Climate Fund and other donors. This is one of at least four health initiatives that will be launched by the UK COP26 Presidency, which is making health a central pillar of the Climate Change COP, and its 5-year renewal of commitments to the 2015 Paris agreement.


Leads: Global Water Partnership (GWP) and the Alliance for Global Water Adaptation (AGWA).

Countries: Indonesia, Malawi, Egypt, Costa Rica, The Netherlands, Guinea, the UK

This workstream will address challenges and innovations around climate change and water management. One major initiative is the new Water Tracker, a tool to help countries strengthen water resilience in countries’ national climate planning.

The workstream lists the following three levers for change as means of advancing water resilience for effective climate adaptation:

  • Better information for decision-making
  • Stronger political will
  • Improved financial flows

Locally Led Adaptation

Leads: World Resources Institute (WRI), International Institute of Environmental Development (IIED)

This workstream is focused on changing how adaptation efforts are designed, financed, implemented, and measured, so that local actors are at the center of decision-making. The aim is to bring about a new paradigm where communities and local actors have greater power and resources to build climate resilience.

Join the AAC

World Resources Institute (WRI) is hosting the Secretariat of the AAC. Countries interested in joining the AAC should reach out to Rebecca Carter.

Prospective AAC members are welcome to join us to spotlight how their country:

  • Demonstrates on-the-ground action to respond to climate risks.
  • Can contribute to building the evidence base on good adaptation planning, governance and collaboration to scale-up action.
  • Supports the integration of climate risk into policymaking, planning, budgeting and investment decision making at all levels.
  • Ensures that their adaptation initiatives are driven by partnerships, particularly with local communities and the most vulnerable and marginalized stakeholders
  • Integrates inclusion and operationalizes the Principles for Locally Led Adaptation.

Race to Resilience

The Adaptation Action Coalition partners with and shares common goals with the Race to Resilience, which aims to catalyze action by non-state actors to build the climate resilience of 4 billion people from vulnerable groups and communities. The campaign, led by High-Level Champions for Climate Action Nigel Topping and Gonzalo Muñoz, focuses on helping frontline communities to build resilience and adapt to impacts of climate change, which include extreme heat, drought, flooding and sea-level rise.
