During June 2022, ACCESS held its first Annual Assembly. The Assembly had several objectives, including bringing together a range of partners from different sectors, providing an opportunity for networking early in the project, and enabling discussions around the aims of ACCESS. The Assembly also provided an early opportunity for the Guiding Principles Team to 1) embed principles of Environmental Sustainability, Knowledge Co-Production, and EDI within the Assembly, and 2) use the event as a reflection and benchmarking moment early in the life of ACCESS to inform the ongoing development of the Guiding Principles Charter.
