International agreements and cooperation are important means of supporting implementation. Through the Economic Commission for Europe Convention on Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters (Aarhus Convention),b which was adopted on 25 June 1998 and entered into force on 30 October 2001, countries have been engaged in ensuring that access rights become effective. In Latin America and the Caribbean, a regional instrument whose aim is to ensure the full implementation of access rights and to promote international cooperation in that regard, is currently under negotiation, with the support of the Economic Commission for Latin America and the Caribbean. Further, at the eleventh special session of the United Nations Environment Programme (UNEP) Governing Council/Global Ministerial Environment Forum, held in Bali, Indonesia, from 24 to 26 February 2010, the Governing Council of UNEP adopted the Guidelines for the Development of National Legislation on Access to Information, Public Participation and Access to Justice in Environmental Matters (Bali Guidelines).'
