In July 2017, the UN adopted the Treaty on the Prohibition of Nuclear Weapons, which forbids all activities related to nuclear weapons: testing, building, funding and even threatening to use them.

This process is different in each city, so get in touch with your local authorities to ask which steps you'll need to take.
