In 2011, in a response to UN General Assembly Resolution 63/51 on the observance of environmental norms in the drafting and implementation of agreements on disarmament and arms control, the representative of Cuba stated:
The Republic of Cuba has accumulated vast experience in the adoption and application of laws and policies that allow it to observe environmental norms … including their application in various International Instruments in the field of disarmament and arms control to which it is a State Party: [including] the [1972] Biological Weapons Convention (BWC), … among others.
Cuba affirms that the only truly effective solution to avoid the dire consequences of the use of weapons of mass destruction continues to be the total elimination of this type of weapons, and considers the universalisation of international treaties that prohibit them of great importance. The existence and continuous refinement of weapons of mass destruction constitute the most serious threat to international peace and security, the fragile environmental balance of our planet and the sustainable development of all peoples without distinction.
Strengthening the Convention on Biological Weapons is essential to protecting the environment and preserving the biodiversity of our planet. The draft protocol for strengthening the Convention, which was the subject of negotiations some years ago, included proposals … [for measures for protecting the environment in the implementation of the Convention]. Negotiations for the adoption of this protocol must be resumed, and Cuba hopes that this will be decided at the upcoming Seventh Review Conference of States Parties to the Biological Weapons Convention in December 2011.
