8. Implement alternative energy sources
Several hotels have switched some of their energy usage to alternative sources, with great results. The Willard Intercontinental in Washington D.C. is now running on 100% wind energy power, resulting in a 12% decline in energy consumption, according to the Green Hotels and Responsible Tourism Initiative.
Other hotels, particularly those in warmer climates, are making use of solar energy for signage and water heating. And as the market for alternative energy increases, more solutions will arise.
9. Upgrade your transportation offerings and services with sustainability in mind
Add electric vehicle charging stations for guests with electric or hybrid cars. Consider eBike and eScooter rental options to promote sustainable transportation (be sure to provide helmets for guests). Provide group shuttles (using hybrid or electric vehicles) to public transit hubs to cut down on the number of low-occupancy car trips to and from your hotel.
