Net Zero


Our plenary talks in the morning session all address the topic of Net Zero emissions: the balance of greenhouse gas sources and sinks required to stabilise global temperature. The afternoon parallel sessions include themes that range from fundamental scientific insights and break-throughs to highly applied, user-facing applications. We aim to create dialogue across the spectrum of activity which helps to strengthen the science,  improve communication between our research activities and assist with the translation into applications. The collective aim is to provide us all with an opportunity to discuss and update each other on the latest developments from right across our discipline and share our science and its application.
