Australia
In 1991, in briefing notes prepared for a debate on the Geneva Convention Amendment Bill in Australia’s House of Representatives, the Australian Department of Foreign Affairs and Trade expressed the view that:
The extension in [the 1977 Additional Protocol I of the prohibition of reprisals] is to civilian, cultural and other non-military objects. It was felt that an Australian reservation on this point, while leaving the way open for us to use such reprisals, would not only allow Australia to be portrayed as barbaric but also leave such Australian objects open to attack in enemy reprisals, in return for very little military advantage. This is now a settled Australian Defence Force view.

This prohibition of reprisal is absolute and applies to the use of all weapons. In consequence, the protected persons and objects can never become targets of any attack, including nuclear attacks. The provisions of the Conventions and the Protocols carrying this prohibition of reprisals against protected persons and objects are considered declaratory of customary law.

Solomon Islands
In 1994, in its written statement submitted to the ICJ in the Nuclear Weapons (WHO) case, the Solomon Islands, referring to Articles 20, 51(6), 52(1), 53, 54(4), 55(2) and 56(4) of the 1977 Additional Protocol I, stated:
During hostilities, it is forbidden to resort to reprisals against … various categories of civilian property which are subject to special protection … The prohibition applies in respect of all weapons, including nuclear weapons. This rule had previously been established in a general manner by Art. 60(5) of the 1969 Vienna Convention of the Law of Treaties … A similar provision is set forth in paragraph 7 of the UN General Assembly resolution 2675 (XXV) … The prohibition of reprisals in these situations appears also in Principle 1, paragraph 6 of UN General Assembly resolution 2625 (XXV) on friendly relations. Even if, in that case, it relates to Jus ad (or contra) bellum rather than jus in bello, it is nonetheless applicable to the second. It follows from the above that reprisals can, in no circumstances, be lawful against this category of targets. 
Solomon Islands, Written statement submitted to the ICJ, Nuclear Weapons (WHO) case, 9 June 1994, § 3.75.
Switzerland
Switzerland’s ABC of International Humanitarian Law (2009) states:
Means and methods of warfare
Even in war not everything is allowed. Various means and methods are prohibited, including … Reprisals against the civilian population or against non-military objectives[.]
Reprisals
International humanitarian law does not include any general prohibition of reprisals. There are however numerous provisions that prohibit specific types of reprisal … Also prohibited are reprisals against certain specific objects such as … the natural environment[.] 
Switzerland, Federal Department of Foreign Affairs, ABC of International Humanitarian Law, 2009, pp. 29 and 37.
Ukraine
At the CDDH, Ukraine stated that it “agreed with those who had mentioned the need to prohibit reprisals and damage to the natural environment”. 
Ukraine, Statement at the CDDH, Official Records, Vol. XIV, CDDH/III/SR.16, 10 February 1975, p. 140, § 59.
United Kingdom of Great Britain and Northern Ireland
In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, the United Kingdom stated:
To be lawful, a belligerent reprisal must meet two conditions. First, it must not be directed against persons or objects against which the taking of reprisals is specifically prohibited … Additional Protocol I prohibits the taking of reprisals against … the natural environment (Article 55(2)) … The application of these provisions would have a greater effect on the retaliatory use of nuclear weapons. Again, however, these provisions are correctly regarded as innovative and thus as inapplicable to the use of nuclear weapons. 
United Kingdom, Written statement submitted to the ICJ, Nuclear Weapons case, 16 June 1995, pp. 58–59.
United Kingdom of Great Britain and Northern Ireland
Upon ratification of the 1977 Additional Protocol I, the United Kingdom stated:
The obligations of Articles 51 and 55 are accepted on the basis that any adverse party against which the United Kingdom might be engaged will itself scrupulously observe those obligations. If an adverse party makes serious and deliberate attacks, in violation of Article 51 or Article 52 against the civilian population or civilians or against civilian objects, or, in violation of Articles 53, 54 and 55, on objects or items protected by those Articles, the United Kingdom will regard itself as entitled to take measures otherwise prohibited by the Articles in question to the extent that it considers such measures necessary for the sole purpose of compelling the adverse party to cease committing violations under those Articles, but only after formal warning to the adverse party requiring cessation of the violations has been disregarded and then only after a decision taken at the highest level of government. Any measures thus taken by the United Kingdom will not be disproportionate to the violations giving rise thereto and will not involve any action prohibited by the Geneva Conventions of 1949 nor will such measures be continued after the violations have ceased. The United Kingdom will notify the Protecting Powers of any such formal warning given to an adverse party, and if that warning has been disregarded, of any measures taken as a result.

United States of America
In 1987, in submitting the 1977 Additional Protocol II to the US Senate for advice and consent to ratification, the US President announced his decision not to ratify the 1977 Additional Protocol I, stating, inter alia, that the Additional Protocol I “fails to improve substantially the compliance and verification mechanisms of the 1949 Geneva Conventions and eliminates an important sanction against violations of those Conventions”.

UN Commission of Experts Established pursuant to Security Council Resolution 780 (1992)
In 1994, in its final report on grave breaches of the Geneva Conventions and other violations of IHL committed in the former Yugoslavia, the UN Commission of Experts Established pursuant to Security Council Resolution 780 (1992), referring to Article 55(2) of the 1977 Additional Protocol I, stated: “Reprisals against the following categories of persons and objects are specifically prohibited: … (i) The natural environment”. 
UN Commission of Experts Established pursuant to Security Council Resolution 780 (1992), Final report, UN Doc. S/1994/674, 27 May 1994, § 65.
The Commission further stated:
In international armed conflicts to which the four Geneva Conventions and Additional Protocol I apply, lawful reprisals … must be directed exclusively against combatants or other military objectives subject to the limitations contained in the Geneva Conventions, Protocol I and customary international law of armed conflicts. In international armed conflicts where Additional Protocol I does not apply, reprisals may be directed against a much wider category of persons and objects, but subject to the limitations of customary international law of armed conflicts.

International Court of Justice
In its advisory opinion in the Nuclear Weapons case in 1996, the ICJ observed that any right of recourse to reprisals would, like self-defence, be governed by the principle of proportionality. The Court noted:
Articles 35, paragraph 3, and 55 of Additional Protocol I provide additional protection for the environment. Taken together, these provisions embody a general obligation to protect the natural environment against widespread, long-term and severe environmental damage; the prohibition of methods and means of warfare which are intended, or may be expected, to cause such damage; and the prohibition of attacks against the natural environment by way of reprisals.
These are powerful constraints for all the States having subscribed to these provisions.

The ICRC Guidelines for Military Manuals and Instructions on the Protection of the Environment in Times of Armed Conflict provides: “Attacks against the natural environment by way of reprisals are prohibited.”
