The Aarhus Convention (UNECE, 1998) arose out of Principle 10 (UNEP) of the Rio Declaration 1992 (UN,
1992), which embodies a key principle of international environmental law, that environmental decisions
are best handled with the participation of those concerned. The three pillars of the Convention are Access
to Information about the Environment, Public Participation in Environmental Decision Making and Access
to Justice when these rights are denied. Implementation measures have been undertaken by the EU in the
areas of Information and Participation rights and this is the main way these obligations make their way
into Irish Law (e.g. the EIA Directive (Environmental Impact Assessment) and Access to Environmental
Information (AIE) Regulations). The Convention has been declared an integral part of the EU legal order.
