It requires states-parties that currently have nuclear weapons to destroy them and those that have nuclear weapons on their territory to remove them. States-parties must also provide victim assistance to those impacted by nuclear weapon use and testing and environmental remediation assistance to areas impacted by nuclear weapon use and testing.
