The EU is a Party to the Aarhus Convention (the Convention on Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters), which establishes a set of environmental law standards in those areas. While implementing the Convention, the EU sometimes went beyond but other times has fallen short of the standards established. Any member of the public can bring a communication before the Aarhus Compliance Committee concerning the EU’s compliance with the Convention. After a communication regarding the «individual concern» standing criteria for individuals and NGOs to challenge decisions of EU institutions, the Committee found that the EU failed to comply with its obligations with regard to access to justice by members of the public, a decision that is still under appreciation by the MoP. The paper will focus on the EU’s compliance with the environmental standards established and the role of the Committee (an external body) in controlling it.
