With Earth Day approaching on April 22, some of the world’s most eco-friendly hotels invite guests to celebrate sustainable choices and initiatives with a stay at their properties.

Hôtel Barrière Le Carl Gustaf St. Barth

Located on the island of St. Barth, the 21-room hotel features a system of machines throughout the property that recovers humidity in the ambient air to transform into water. The systems not only create this water but also create water free of any chlorine, chemicals and pollutants. Using carbon filters and UV lamps, the water is then bottled in the resort’s organic and completely recyclable glass.

In turn, the resort offers guests L’Eau du Carl, or water “made” in Le Carl in a bid to be more sustainable and eco-conscious. The water can be found throughout the resort and minibar.

Hyatt Regency Maui Resort & Spa

A longtime leader in sustainable efforts, Hyatt Regency Maui Resort & Spa was the first property in Hawai’i and first large-scale beach resort in the world awarded the U.S. Green Building Council TRUE Waste Precertification.

After completing its multimillion-dollar renovation in 2014, the resort reported, during the renovation, it diverted more than 5 million pounds of waste from the Maui landfill by donating more than 1,716 tons of furniture, mattresses, artwork, mirrors and other items to local businesses and charities. Additionally, the resort recycled more than 750 tons of metals.

As the property continues to set a high standard in sustainability in the hospitality world, Hyatt Regency Maui Resort & Spa aims to implement more initiatives in various categories. The resort has already set its sights on food and food waste, renewable energy, green cleaning, indoor air quality and staff training.
