In early 2021, the United Nations Office for Outer Space Affairs (UNOOSA) convened a multi-stakeholder event series to raise awareness on the topic of space sustainability and to provide a platform for the sharing of related operational experience.
The events facilitated peer-to-peer dialogue and an exchange of existing sustainable space practices, as mapped to the Guidelines for the Long-term Sustainability of Outer Space Activities (LTS Guidelines). Each event engaged contributors from across the international space sector. Through case studies and lessons learned, the events facilitated capacity-building for other operators and stakeholders looking to enhance the sustainability of their own space activities.
The events highlighted experts representing:
Commercial space sector
Space agency operators
Regulators and policymakers

Focus: Practical measures from the viewpoint of commercial operators to implement the LTS Guidelines in mission design, on-orbit operations and post-mission disposal.
Commercial space sector event summary report
Focus: How space agencies coordinate operations, share data and manage risk to operationalize the LTS Guidelines.
Space agency operators event summary report
