Nowadays, corporate business leaders have become more serious and responsive to protecting the natural environment, in part due to rising public attention toward environmental issues (Qiet al., 2011). Presently, company executives are working alongside environmentalists to find ways to reduce pollution, creating a ‘winewin’ situation (Clarke and Fuller, 2011). Pollution prevention protects the environment, consumers and workers; in addition,
the improvement of industrial efficiency, profitability and competitiveness can be achieved (Ngwakwe, 2011).
