CND has been contacting embassies in London of countries that have signed but not ratified the global ban. In response to our inquiries, the embassy of Brazil responded stating:
I would like to thank you for your letter, which was brought to the Ambassador’s attention.
The Treaty on the Prohibition of Nuclear Weapons is currently under consideration by the Brazilian Congress, where it must be approved before ratification.
