To make sustainability a success there are three elements to bring together: the environment (carbon), society (people), and business economics (cost savings).
Offering a flexible working policy is one example of improving workplace sustainability. One study in the United States found that switching from working onsite to working from home reduced up to 58% of work's carbon footprint.
For the environment, cutting commuter emissions lowers the carbon footprint. For employees, it improves work life balance and productivity. And for cost savings in the business, it reduces overhead office costs such as heating buildings and desk space.
