Collision risk from space debris. Policy options

Improving risk assessment and conducting thorough cost-benefit analyses of the different proposed management options are of paramount importance to making informed decisions. However, getting a comprehensive picture of a complex, ambiguous and uncertain risk is likely unachievable, and the lack thereof should not be a reason to postpone action. The numerous risk analyses conducted so far have produced actionable information and steps can be taken to reduce risk, as shown with the policy options presented in this document. As technologies mature, more information regarding their costs and benefits will be available to decision-makers. This policy brief provides a range of policy options to improve the assessment, evaluation and management of collision risk, as well as its communication.
