At the Seventh Environment for Europe Ministerial Conference, held in Nur-Sultan in 2011,Ministers decided to develop the Shared Environmental Information System (SEIS) across the region of the United Nations Economic Commission for Europe (ECE). At the Eighth Conference, in Batumi, Georgia, in 2016, Ministers welcomed progress in developing SEIS to support a regular process of environmental assessment and invited countries to continue their efforts and to further develop their national information systems to have SEIS in place in the countries of Europe and Central Asia by 2021.The result has been, overall, the successful establishment of SEIS in Europe and Central Asia. Nonetheless, countries need to address remaining gaps in the implementation of SEIS, covering relevant pillars, thematic categories and data flows. Consequently, SEIS has supported the preparation of the Seventh Pan-European Environmental Assessment, prepared by ECE and the United Nations Environment Programme. The assessment reports that progress has been achieved in environmental protection in certain areas, but significant shortcomings remain and pose a threat to the health of both people and the environment in the pan-European region. This brochure presents for policymakers, particularly those attending the Ninth Environment
for Europe Ministerial Conference, the key messages and recommendations of the pan- European assessment and to address remaining gaps in the implementation of SEIS.
