Taking an expanded view of sustainability as both an ecological and societal imperative, Bella Knemeyer explores mechanisms for measuring impact and implementing change in the global arts ecology. Her project takes A4 as a case study, observing different strategies for exhibition-making, particularly the foundation's focus on how ideas and artworks can travel independently of objects. As part of this research, Bella produces an annual carbon report of A4 and compiles a series of reading lists and resources. Her findings inform A4's first Sustainability Roundtable in London, which brings together arts workers from the museum, foundation, gallery, art fair and philanthropic communities. Piggy-backing on the convening power that is the Frieze Art Fair, arts workers grappling with sustainability practices and their applications within the visual arts gathered for the exchange, which took shape as a sense-making process facilitated from the Global South to North and back. Guiding the discussion is a set of prompt cards that draw together impressions from Harvest Live engagements at A4, as well as quotes from diverse practitioners working in sustainability at large.

Reflecting on the notes from the Sustainability Roundtable, seven themes became apparent: 

Energy, movement and temporalities, 
Artful lobbying groups, 
The responsibilities of artists, institutions and collectors, 
The potential of co-ownership, 
Experimentation and institutional critique, 
Thinking globally and acting locally, and
Green fundraising.
