Environmental protection is now an integral part of everyday company life. Environmental management forms the basis for company environmental protection: its success depends on continuous planning, guidance and control. This is achieved with environmental controlling. Over more than 700 pages, the “Manual on Environmental Controlling” contains all the information needed to establish a successful environmental controlling system. It contains useful knowledge about the basics of environmental controlling, strategic environmental controlling, analysis and evaluation, environmentally oriented products, environmental protection in the production phase, environmental cost and investment accounting as well as information systems. Small and medium-sized enterprises in particular can find practical tips and intersectoral information here – and in a clearly laid-out and compact form. The first edition of the manual was named “Reference book of 1995 on environmental management” by the Federation of German Management Consultants (BDU)
