As the Peninsula Principles note in the Preamble, while climate displacement can involve both internal and cross-border displacement, most climate displacement will likely occur within state borders. This chapter analyses Peninsula Principle 17 and its essential underpinnings in more detail, as well as some of the practical steps that must be taken to implement them. In so doing, it draws on relevant provisions of the Guiding Principles on Internal Displacement. At the core of Peninsula Principle 17 is the right to voluntary return in safety and dignity, one of the three so-called 'durable solutions' to displacement. Voluntary return also involves access to objective information (including on physical, material and legal safety issues). A critical component in many contexts for the sustainability of return is the restitution of property that displaced persons left behind. The Pinheiro Principles details specific measures that should be taken to ensure equal access for women also.
