The International Organization for Standardization (ISO) has developed over 18 500 international standards on a variety of issues. The ISO 14000 standard is primarily concerned with “environmental management”. In effect, it codifies what practices and standards companies should follow to minimize harmful impacts on the environment caused by their activities and to achieve continual improvement of environmental performance. With annual growth rates of over 30% and 230 000 certificates granted in 2009, this development demonstrates a growing number of companies’ commitment to adopting environmental management systems.
