But what about costs? Yes, there is an upfront investment in money and time, but the payoff is clear. Even during this recession, as you focus on the bottom line and try to save wherever possible, you can actually reduce operating expenses through green initiatives. In fact, relatively small investments can yield big potential returns. Plus, consider the additional benefits that sustainability can lead to: more effective recruiting, improved worker productivity, lower absenteeism, better employee retention, and enhanced corporate branding.
