Practice Relating to Rule 44. Due Regard for the Natural Environment in Military Operations
The Report on the Practice of Zimbabwe recalls Zimbabwe’s adoption of the 1992 Rio Principles as evidence that environmental protection during armed conflict forms an important component of Zimbabwe’s view of IHL. It also refers to “various pieces of legislation” dealing with environmental protection and setting up standards to be observed at all times, “whether or not there is armed conflict”, as evidence of Zimbabwe’s view that the environment should be protected even in times of armed conflict. 
Report on the Practice of Zimbabwe, 1998, Chapter 4.4.
