AU4DM is a community of researchers and professionals from policy, industry, and academia, seeking to improve decision-making under uncertainty. The core of our work is decision science. At the same time, we have discovered the value of sparkling interdisciplinary collaboration across the social sciences and arts and humanities. On 1 October 2021, AU4DM teamed up with Climate Action Unit to host a special workshop on Communicating Climate Risk, supported by Cambridge Zero and the COP26 Universities network.
