Chapter 39. International Legal Instruments and Mechanisms
Basis for action
39.1. The recognition that the following vital aspects of the universal, multilateral
and bilateral treaty-making process should be taken into account:
(a) The further development of international law on sustainable development, giving
special attention to the delicate balance between environmental and developmental
concerns;
(b) The need to clarify and strengthen the relationship between existing international
instruments or agreements in the field of environment and relevant social and economic
agreements or instruments, taking into account the special needs of developing countries;
(c) At the global level, the essential importance of the participation in and the
contribution of all countries, including the developing countries, to treaty making in the
field of international law on sustainable development. Many of the existing international
legal instruments and agreements in the field of environment have been developed without
adequate participation and contribution of developing countries, and thus may require
review in order to reflect the concerns and interests of developing countries and to
ensure a balanced governance of such instruments and agreements;
(d) Developing countries should also be provided with technical assistance in their
attempts to enhance their national legislative capabilities in the field of environmental
law;
(e) Future projects for the progressive development and codification of international
law on sustainable development should take into account the ongoing work of the
International Law Commission;
(f) Any negotiations for the progressive development and codification of international
law concerning sustainable development should, in general, be conducted on a universal
basis, taking into account special circumstances in the various regions.
Objectives
39.2. The overall objective of the review and development of international
environmental law should be to evaluate and to promote the efficacy of that law and to
promote the integration of environment and development policies through effective
international agreements or instruments taking into account both universal principles and
the particular and differentiated needs and concerns of all countries.
39.3. Specific objectives are:
(a) To identify and address difficulties which prevent some States, in particular
developing countries, from participating in or duly implementing international agreements
or instruments and, where appropriate, to review and revise them with the purposes of
integrating environmental and developmental concerns and laying down a sound basis for the
implementation of these agreements or instruments;
(b) To set priorities for future law-making on sustainable development at the global,
regional or subregional level, with a view to enhancing the efficacy of international law
in this field through, in particular, the integration of environmental and developmental
concerns;
(c) To promote and support the effective participation of all countries concerned, in
particular developing countries, in the negotiation, implementation, review and governance
of international agreements or instruments, including appropriate provision of technical
and financial assistance and other available mechanisms for this purpose, as well as the
use of differential obligations where appropriate;
(d) To promote, through the gradual development of universally and multilaterally
negotiated agreements or instruments, international standards for the protection of the
environment that take into account the different situations and capabilities of countries.
States recognize that environmental policies should deal with the root causes of
environmental degradation, thus preventing environmental measures from resulting in
unnecessary restrictions to trade. Trade policy measures for environmental purposes should
not constitute a means of arbitrary or unjustifiable discrimination or a disguised
restriction on international trade. Unilateral actions to deal with environmental
challenges outside the jurisdiction of the importing country should be avoided.
Environmental measures addressing international environmental problems should, as far as
possible, be based on an international consensus. Domestic measures targeted to achieve
certain environmental objectives may need trade measures to render them effective. Should
trade policy measures be found necessary for the enforcement of environmental policies,
certain principles and rules should apply. These could include, inter alia, the principle
of non-discrimination; the principle that the trade measure chosen should be the least
trade-restrictive necessary to achieve the objectives; an obligation to ensure
transparency in the use of trade measures related to the environment and to provide
adequate notification of national regulations; and the need to give consideration to the
special conditions and development requirements of developing countries as they move
towards internationally agreed environmental objectives;
(e) To ensure the effective, full and prompt implementation of legally binding
instruments and to facilitate timely review and adjustment of agreements or instruments by
the parties concerned, taking into account the special needs and concerns of all
countries, in particular developing countries;
(f) To improve the effectiveness of institutions, mechanisms and procedures for the
administration of agreements and instruments;
(g) To identify and prevent actual or potential conflicts, particularly between
environmental and social/economic agreements or instruments, with a view to ensuring that
such agreements or instruments are consistent. Where conflicts arise they should be
appropriately resolved;
(h) To study and consider the broadening and strengthening of the capacity of
mechanisms, inter alia, in the United Nations system, to facilitate, where appropriate and
agreed to by the parties concerned, the identification, avoidance and settlement of
international disputes in the field of sustainable development, duly taking into account
existing bilateral and multilateral agreements for the settlement of such disputes.
Activities
39.4. Activities and means of implementation should be considered in the light of the
above basis for action and objectives, without prejudice to the right of every State to
put forward suggestions in this regard in the General Assembly. These suggestions could be
reproduced in a separate compilation on sustainable development.
A. Review, assessment and fields of action in international law for sustainable
development
39.5. While ensuring the effective participation of all countries concerned, Parties
should at periodic intervals review and assess both the past performance and effectiveness
of existing international agreements or instruments as well as the priorities for future
law making on sustainable development. This may include an examination of the feasibility
of elaborating general rights and obligations of States, as appropriate, in the field of
sustainable development, as provided by General Assembly resolution 44/228. In certain
cases, attention should be given to the possibility of taking into account varying
circumstances through differential obligations or gradual application. As an option for
carrying out this task, earlier UNEP practice may be followed whereby legal experts
designated by Governments could meet at suitable intervals, to be decided later, with a
broader environmental and developmental perspective.
39.6. Measures in accordance with international law should be considered to address, in
times of armed conflict, large-scale destruction of the environment that cannot be
justified under international law. The General Assembly and its Sixth Committee are the
appropriate forums to deal with this subject. The specific competence and role of the
International Committee of the Red Cross should be taken into account.
39.7. In view of the vital necessity of ensuring safe and environmentally sound nuclear
power, and in order to strengthen international cooperation in this field, efforts should
be made to conclude the ongoing negotiations for a nuclear safety convention in the
framework of the International Atomic Energy Agency.
B. Implementation mechanisms
39.8. The parties to international agreements should consider procedures and mechanisms
to promote and review their effective, full and prompt implementation. To that effect,
States could, inter alia:
(a) Establish efficient and practical reporting systems on the effective, full and
prompt implementation of international legal instruments;
(b) Consider appropriate ways in which relevant international bodies, such as UNEP,
might contribute towards the further development of such mechanisms.
C. Effective participation in international law making
39.9. In all these activities and others that may be pursued in the future, based on
the above basis for action and objectives, the effective participation of all countries,
in particular developing countries, should be ensured through appropriate provision of
technical assistance and/or financial assistance. Developing countries should be given
"headstart" support not only in their national efforts to implement
international agreements or instruments, but also to participate effectively in the
negotiation of new or revised agreements or instruments and in the actual international
operation of such agreements or instruments. Support should include assistance in building
up expertise in international law particularly in relation to sustainable development, and
in assuring access to the necessary reference information and scientific/technical
expertise.
D. Disputes in the field of sustainable development
39.10. In the area of avoidance and settlement of disputes, States should further study
and consider methods to broaden and make more effective the range of techniques available
at present, taking into account, among others, relevant experience under existing
international agreements, instruments or institutions and, where appropriate, their
implementing mechanisms such as modalities for dispute avoidance and settlement. This may
include mechanisms and procedures for the exchange of data and information, notification
and consultation regarding situations that might lead to disputes with other States in the
field of sustainable development and for effective peaceful means of dispute settlement in
accordance with the Charter of the United Nations, including, where appropriate, recourse
to the International Court of Justice, and their inclusion in treaties relating to
sustainable development.
