Sustainability is not a technological issue. At its core it is a behavioural issue and as such it is dependent upon teamwork, co-operation and motivation. For sustainable practices to take root and produce results, every employee - whether he or she is a cleaner, a production line worker, or an administrator - must contribute to the process (even paying customers). No matter what level or experience a person has, everyone has the potential to discover a sustainable path that has been overlooked. Just as important, any employee has the ability to add that final jolt of effort that avoids failure and promotes success. Understanding the importance of people in all phases of the sustainability process is necessary to ensure that a thorough and combined effort on all fronts is made. Simply put, people are a business’s ultimate competitive advantage.
