However, only 17 furnaces have been closed so far. UNEP Executive Director, Mr. Achim Steiner commented that the 2012 Yearbook draws attention to two emerging issues, emphasizing challenges but also offering options for countries to consider having a 21st century. sustainable - urgently improving land management and the closure of nuclear power reactors.
