Portugal

Nuclear-weapon endorser

Did not participate in TPNW negotiations

Has not yet joined TPNW

Portugal supports the retention and potential use of nuclear weapons on its behalf, as indicated by its endorsement of various alliance statements of the North Atlantic Treaty Organisation (NATO), of which it is a member.

Portugal has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. Portugal did not participate in the negotiation of the treaty at the United Nations in New York in 2017 and thus did not vote on its adoption.

Portugal voted against a UN General Assembly resolution in 2019 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.

In 2016, Portugal voted against the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

In a “non-paper” sent to NATO members ahead of the vote, the United States “strongly encourage[d]” members, including Portugal, to vote against the resolution, “not to merely abstain”. In addition, it said that, if the treaty negotiations do commence, allies and partners should "refrain from joining them”.
