Sustainability Accelerator Microgrants 2024

Deadline Date: April 15, 2024

Donor Name: Chatham House Sustainability Accelerator

Grant Size: $1000 to $10,000

The Chatham House Sustainability Accelerator is looking for innovative and engaging ideas that accelerate innovative policy solutions for a fair and sustainable future – for the environment and for people.

They would like to empower and bring together the thought leaders and changemakers of tomorrow who will have a crucial role in shaping a sustainable future.

Everyone can submit their idea, whether you’re an activist, changemaker, policymaker, disruptor or member of the public, they want to hear from you.

Grants of £1,000 are available for innovative and creative people to transform their ideas for sustainability solutions into reality.

The microgrants will provide a springboard for novel ideas to solve sustainability challenges. Your idea should lead to a tangible output or process that could be implemented in different geographies and contexts. This could be a digital tool, a physical product, an event, or even work to shape or influence a policy idea. You need to demonstrate how it could help to:

  • Solve an existing sustainability issue, preferably in a way that could be implemented by policymakers worldwide.
  • Accelerate progress towards international sustainability targets.

Ideas should also demonstrate their resonance based on a combination of relevance (how important it is) and reach (how scalable it is across a range of geographic contexts).


  • This is a unique opportunity for individuals and groups to bring to life their idea for an innovative sustainability solution. Whether you use it to get a project off the ground, or scale-up an existing one, they hope the grant enables you to turn your thoughts into action.
  • You must meet the following eligibility requirements:
    • You do not need to be a Chatham House member to apply!
    • They welcome applications from all backgrounds and geographies.

    • If applying in a partnership, there must be one primary applicant who will receive the grant funding and will hold overall responsibility for the initiative.
