We are so close to seeing a new United Nations treaty enter into force, one which will make nuclear weapons illegal in the countries that sign it. The countdown is really on!

The Treaty on the Prohibition of Nuclear Weapons (TPNW) needs 50 countries to ratify it before it becomes international law. And as of today, 47 countries have done so, with a further 84 signing it. Who will be next?

Shamefully the UK government refused to even participate in the treaty talks and now says it will never sign. But that will not stop us from making progress. From its founding meeting, CND has championed the global abolition of nuclear weapons. This treaty is a victory for grassroots campaigning and our anti-nuclear movement. The 2017 Nobel Peace Prize was even awarded to ICAN – of which CND is a partner – for its tireless work in campaigning for this momentous achievement.

What will it mean when the TPNW enters into force?

The terms of the TPNW only apply to the countries that have signed and ratified the agreement. And although the nine nuclear-armed states currently state they will not support it, the treaty is a significant pointer towards changing international attitudes to nuclear weapons. Previous treaties prohibiting chemical and biological weapons helped to stigmatise them in the minds of the public. This is now taking place with nuclear weapons.

This historic agreement will no doubt generate international momentum towards global nuclear abolition. The treaty is a breakthrough in international disarmament efforts and will be of enormous support in achieving the goal that most of the world shares: that there is no place for these weapons of mass destruction.

Alongside raising awareness of the TPNW, CND will continue to work with all our partners in Parliament and across civil society to oppose the replacement of Trident.

What can I do to support the campaign?

Nuclear Ban Communities

Join CND

  • Since 1958 CND has been the voice for the millions of people in this country who want to prevent nuclear Armageddon. It’s more important than ever to join CND, to stand with us as we prepare to mark this momentous achievement and renew our determination to achieve a world without nuclear weapons.

Get ready for the 50th ratification

  • The 50th ratification could happen very soon and when it does, we’re asking all CND supporters to prepare for an action that day. Due to Covid-19 restrictions, we very likely won’t be able to gather together in one place and so we’re asking you to create a CND symbol in your garden or home. Be as creative as you can! You could use ribbons, material or everyday items. Tealights outside could also look good. Take a photo and post on social media or send to information@cnduk.org. Let’s make sure we mark this momentous moment in our campaign!
