The European Council and the Council of the EU are two very closely linked institutions. They have similar names and share the same buildings and staff - the General Secretariat of the Council (GSC). However, they have very different roles and membership.
On 30 June 2016 the Council and the European Parliament reached a provisional agreement on a directive to reduce emissions of air pollutants.
This new directive sets stricter national limits for the emissions of five pollutants including NOx or ammonia. New, stricter emission limits for each pollutant are set for the period from 2020 to 2029 and from 2030 onwards.
With these new commitments, the health impact of air pollution is estimated to be reduced by about 50% in 2030 compared to 2005.
"We are determined to remain united and work in the framework of the EU to deal with the challenges of the 21st century and find solutions in the interest of our nations and peoples," said the 27 leaders in their joint statement after the informal meeting on 29 June. They also called on the UK government to notify the European Council of its intention to withdraw from the EU as quickly as possible.
The 27 leaders will meet again in September to continue talks on the future of the EU.
A day earlier, on 28 June, the European Council also focused on the outcome of the UK referendum. Prime Minister David Cameron presented the situation in the country after the vote.
The EU leaders also addressed other pressing issues: migration, external relations and the economic situation.
