Principle 10
Environmental issues are best handled with participation of all
concerned citizens, at the relevant level. At the national level, each
individual shall have appropriate access to information concerning the
environment that is held by public authorities, including information on
hazardous materials and activities in their communities, and the
opportunity to participate in decision-making processes. States shall
facilitate and encourage public awareness and participation by making
information widely available. Effective access to judicial and
administrative proceedings, including redress and remedy, shall be
provided.
