The second session of the IPU Committee on UN Affairs focused on Nuclear Weapons - The Road to Zero. The speakers on this panel were Mr G Evans (former Foreign Minister, Australia), Mr T Toth (Executive Secretary of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organisation), Dr R Johnson (Executive Director, Acronym Institute for Disarmament Diplomacy), Dr R Chengeni, MP (Tanzania) and Mr M Robson (former Minister for Disarmament and Arms Control, New Zealand). This session created an opportunity to follow-up on the IPU resolution on Advancing nuclear non-proliferation and disarmament and securing the early entry into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), Ethiopia, 2009). The Committee took stock of progress and examined the new visions, policies and proposals that have been put forward to eliminate nuclear weapons. All the presenters lobbied for the banning of all nuclear weapons as the only solution to ensuring the elimination of all nuclear weapons. They also stressed that it is important to bring this item back to the centre of the global policy agenda. The catastrophic human consequences of the use of nuclear weapons i.e. radiation, human contamination and sickness, environmental contamination was highlighted. It is necessary to raise awareness of the humanitarian consequences, reinforce international humanitarian laws and create the framework for the enforcement of conventions. The international community must mobilize and act against the use of nuclear weapons; it should be declared an act against humanity.
