Practice Relating to Rule 147. Reprisals against Protected Objects
Section E. Natural environment
In 1992, prior to the adoption of a UN General Assembly resolution on the protection of the environment in times of armed conflict, Jordan and the United States submitted a memorandum entitled “International Law Providing Protection to the Environment in Times of Armed Conflict” which provided, inter alia:
For States parties the following principles of international law, as applicable, provide additional protection for the environment in times of armed conflict: Article 55(2) of Additional Protocol I prohibits States parties from attacking the natural environment by way of reprisals. 
Jordan and United States, International Law Providing Protection to the Environment in Times of Armed Conflict, annexed to Letter dated 28 September 1992 to the Chairman of the Sixth Committee of the UN General Assembly, UN Doc. A/C.6/47/3, 28 September 1992, § 2(d).
According to the Report on the Practice of Jordan: “The prohibition of belligerent reprisals against protected persons and property is viewed as customary law … In practice, Jordan never resorted to attacks by way of reprisal.”
