Across the world we are marking 5 years since the Treaty on the Prohibition of Nuclear Weapons became international law.

There are so many ways the Treaty on the Prohibition of Nuclear Weapons is making a difference:

Making nuclear weapons illegal and illegitimate

The treaty has closed the legal gap! Nuclear weapons are now banned under international law. It has also reinforced the nuclear taboo by creating a new international norm that nuclear weapons can never be used because of the catastrophic humanitarian and environmental harm they cause. TPNW states have condemned nuclear threats unequivocally and have encouraged other states to do the same – for example, through the G20. The TPNW is the first multilateral treaty to prohibit nuclear threats. It has solidified the international consensus that nuclear threats are inadmissible.

Demanding nuclear justice

Prior to the TPNW’s entry into force, there were few opportunities for states to discuss victim assistance and environmental remediation in a multilateral setting and in a focused way. The Treaty has brought the fight for nuclear justice to the fore and provided an important forum for communities affected by the use and testing of nuclear weapons to discuss their ongoing needs.

Cutting financial support for nuclear weapons manufacture, development and production

Hundreds of banks, pension funds and other financial institutions have pledged never to finance nuclear-weapon-producing companies on the basis that such weapons are now prohibited under international law.

Providing a rallying place for those who demand an end to nuclear weapons forever

Representatives of hundreds of non-government organisations, along with parliamentarians, mayors, religious leaders and academics, have attended each of the TPNW meetings of states parties. New actors have become involved.

Action Ideas: What can I do?

Nuclear weapons affect all of us, so it’s up to all of us to push back against the threats and absurd concept that they provide any security whatsoever. This anniversary is an opportunity to celebrate that the global majority of countries have signed onto the Treaty.
