Content Description

This year's symposium is part of a series to discuss the important contributions of space applications and technologies in tackling the challenges of climate change.

The focus of the symposium is to showcase the most recent initiatives, experiences and best practices in mitigating and adapting to climate change and supporting sustainability on Earth.

Further to creating awareness of how Member States use space technologies, the symposium will highlight how the space sector is being adapted to reduce its own impact on the climate crisis. The symposium would collect ideas and contributions to define future activities.


The Program will focus on the following topics:

  • Case studies on using space applications for adaptation to the climate crisis at the country-level in Slovenia, Egypt and/or Brazil;
  • Specific recent innovative use of space applications to mitigate the impact of the climate crisis, in the areas of transport, energy production, or food production;
  • Changes in space engineering practices and innovations to reduce the contribution of space activities to the climate crisis, as well as regulatory incentives for their adoption.
