The European Union’s environmental agency says air pollution is slowly improving across the continent but still exceeds the bloc’s limits and guidelines from the U.N. health agency.

The European Environment Agency on Monday issued its 2018 report on air quality and said emissions from road traffic, agriculture, energy production, industry and households are churning out pollutants like particulate matter, nitrogen dioxide and ground-level ozone.
