Marseille 2021 Highlights
Sustainability focus

IUCN aims to make significant strides in event sustainability by introducing a range of initiatives focused on venue, travel, and procurement practices.
IUCN is dedicated to leading by example in sustainable events management. Building on the success of previous initiatives, including the ISO 20121 certification awarded to the IUCN World Conservation Congress 2016 in Hawaii and IUCN Congress 2021 in Marseille, IUCN is working to further enhance its sustainable event management practices.
Working collaboratively with the Global Destination Sustainability Movement (GDS-Movement), a pioneering international agency dedicated to driving positive socio-economic and environmental transformation, and Green Evénements, an expert in developing responsible event strategies, IUCN is working towards achieving ISO 20121 certification once again. Specific actions include:
- minimising the environmental impact of its events by reducing greenhouse gas emissions
- minimising resource demand, and
- promoting good sustainability practices to participants, suppliers, and local communities
