The Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) is headed by Dr. Barbara Hendricks, Federal Environment Minister. Next in line are the two Ministers of State, Rita Schwarzelühr-Sutter and Jochen Flasbarth, as well as the State Secretaries Gunther Adler and Florian Pronold. The Ministry has offices in Berlin and Bonn and employs about 1,200 members of staff. For more than 25 years the Ministry has worked to protect the public from environmental toxins and radiation and establish an intelligent and efficient use of raw materials; it has advanced climate action and promoted a use of natural resources that conserves biodiversity and secures habitats. In 2013 the Chancellor issued a decree transferring responsibility for urban development, housing, rural infrastructure, public building law, building, the construction industry and federal buildings to the BMUB.
