On 12 November, ISEAL convened a cross-industry working session at the Zunfthaus zur Zimmerleuten in Zurich, Switzerland, bringing together companies and sustainability systems to strengthen their partnerships for greater impact. This invitation-only workshop, supported by the Swiss State Secretariat for Economic Affairs (SECO), employed an Appreciative Inquiry approach to foster open dialogue about what works well in business-sustainability system partnerships and to collectively identify and prioritise practical improvements for the future.
