Simplify the office common areas and workspaces by reducing clutter and eliminating unnecessary waste. Encourage your coworkers to invest in reusable coffee cups and ditch the one-time use coffee pods and filters. Provide reusable containers and cutlery in the lounge. And, research any eco-friendly alternatives to office purchases and evaluate the necessity of the purchase itself.
Keeping things simple will make your green office initiatives sustainable over the long-haul.
