Take action: urge your country to join the treaty

December 6, 2017

On 7 July 2017, 122 nations voted to adopt a historic global agreement to ban nuclear weapons, known as the Treaty on the Prohibition of Nuclear Weapons. It opened for signature on 20 September. We are calling on all countries to join it without delay.

Please help us put pressure on your government to join by writing to your political leaders or raising public debate about the treaty. Our new booklet explains why the treaty was negotiated and how it will make a difference. We encourage you to share it widely.

Joining the treaty is typically a two-step process. The first step is to sign it – which is a largely symbolic act. The second is to ratify it – which provides formal consent to be legally bound. Ratification often involves the legislative branch of government.

Need more information about joining the treaty? Read this UN kit.

If your government is opposed to the treaty, one of the best things that you can do is enlist the support of individual members of parliament. This can help create pressure and momentum for change. Have you discussed the treaty with your local parliamentarian?

Hundreds of parliamentarians from a wide range of political parties have already formally pledged to work for signature and ratification of the treaty. Most are from countries that currently support nuclear weapons and oppose the treaty.

Does your local parliamentarian support the treaty? Check here.

We encourage you to think creatively about ways to bring your country on board. What kinds of events and activities could raise the profile of the treaty? Are there influential people in your country who might speak out in favour of it?
