Communications Assistant

Hot or Cool Institute is a non-profit, public-interest organisation using science to support policy and advocate action commensurate with the magnitude scale and urgency of the unsustainability crises. Our mission is to equip organisations, policymakers, and communities with the evidence to inform bold action and tools to take radical and responsible actions towards fair and environmentally safe societies.  We are guided by three core values:

  • A society operating within ecological limits
  • Fairness and justice, and
  • Progress that is guided by Well-being for all.

Hot or Cool’s theory of change in tackling the poly-crisis combines three key aspects: a science-based approach that provides the evidence and clarifies the complex nature of the issues, making them accessible to decision-makers and practitioners; building alliances to increase momentum and effectiveness of identified approaches; and understanding and addressing power dynamics in society that undermine change.
