Many business leaders have come to accept the validity of the message that environmental activists have been preaching for decades, namely, that industrial pollution of the environment is an inefficient use of resources that causes both environmental damage and economic losses. Despite this recognition, only a handful of companies are reaping the competitive benefits of integrating environmental, health, and safety (EHS) knowledge into their management decisions. A far greater number are finding the path toward environmental integration extremely difficult to follow. In fact, so widespread is this difficulty that it has entered into the business lexicon as the "green wall" phenomenon.
