A/HRC/27/54 supervisory bodies, and the work undertaken by other special procedures, including his predecessors on this mandate. 26. For his next thematic report, the Special Rapporteur is considering carrying out a study on the right to information in the context of the environmentally sound management and disposal of hazardous substances and wastes. The Universal Declaration of Human Rights (art. 19) and the International Covenant on Civil and Political Rights (art. 19), among other human rights instruments, stipulate that the right to freedom of expression includes the freedom “to seek, receive and impart information”. The right to information is also ensured through a number of international and regional environmental instruments.2 As noted by the then Special Rapporteur on the adverse effects of the illicit movement and dumping of toxic and dangerous products and wastes on the enjoyment of human rights, access to, and the communication of, information about hazardous substances and wastes and their effects on the environment “are essential to guarantee certain other rights, such as the rights to life, to health and to adequate food” (A/HRC/7/21, para. 5). In order to avoid duplicating earlier work, the report will focus on aspects of particular relevance to the tasks mandated under Council resolutions 18/11 and 21/17. 27. The Special Rapporteur looks forward to comments and suggestions from the Council on his plans as outlined in the present document, and particularly to any feedback on methodological issues and the organization of country visits. Furthermore, he looks forward to receiving invitations for country visits from as wide as possible a range of countries, in all regions of the world, and to receiving suggestions in that regard from all stakeholders. The Special Rapporteur welcomes opportunities for collaboration with other relevant mandate holders within their respective mandates. 28. The Special Rapporteur concludes the present report by launching a first appeal to States, relevant United Nations entities, non-governmental organizations, sectoral actors and any other stakeholders to provide him with information and evidence relevant to his mandate, including on situations of particular human rights concern, at their earliest convenience and on an ongoing basis. In addition, he will solicit more specific information on relevant trends and issues as he prepares specific thematic reports and country visits. 2 6 For example, treaties such as the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade (art. 15), the Stockholm Convention on Persistent Organic Pollutants (art. 10), the United Nations Framework Convention on Climate Change (art. 6 (a)) and the Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters (Aarhus Convention), as well as other instruments, such as Principle 10 of the Rio Declaration on Environment and Development.
