Writeup reflecting on the themes from our panel at CHI 2023 on sustainability in HCI (at last!). The panel were myself, Ann Light, Jason Tarl Jacques, Matthew Louis Mauriello, Kathrin Gerling, Robert Soden, Gözel Shakeri, and we were enabled by the SIGCHI sustainability committee and chair Nicola J. Bidwell, Vishal Sharma, and Neha Kumar.  We talk about the need to exercise all our agency (in our research and our academic practice), to recognise the embedding of drivers of unsustainability, and the need to embed and encourage sustainability focused work.
