Hamilton Princess & Beach Club: the First Green Key Site In Bermuda

The Hamilton Princess & Beach Club, a 380-room luxury resort nestled in Bermuda, has made history as the island’s first Green Key-certified property. This prestigious certification, awarded by Green Key International, recognizes the hotel’s commitment to sustainability and its strides in reducing environmental impact through innovative practices.

Tim Morrison, General Manager, Hamilton Princess & Beach Club, said:  

“We are pleased to be recognized by Green Key International as the first in Bermuda. The hotel team have worked hard on this initiative, and the hotel’s Sustainability team, lead by our Champion & Assistant Director of Engineering D’Esta Ascento, were major players in the accomplishment of our goals.” 

 

The resort began its journey toward a more sustainable tourism back in 2016. Tasks began with no single-use plastic in any of the ‘front of house’ areas such as the hotel restaurants and bars. Plastic water bottles were replaced by paper bottles and aluminium reusable water bottles.  Hot and cold drink tumblers were also sold to encourage refilling, and last summer refillable water stations were installed throughout the hotel and Beach Club.

Take-out coffee cups were replaced with a double-insulated version to eliminate the wasteful coffee cup sleeve and the plastic lids were replaced with those made out of composed paper. The stirrers and straws are made from bamboo or hay. Where drinking cups, utensils or containers were needed, the hotel uses products supplied by the Sustainable Agave Company, which have been upcycled and are compostable.  

The hotel also collaborated with ecoSPIRITS, a company which has developed the world’s first low carbon, low waste packaging technology for premium spirits and wine. This international company provides a spirits and wine distribution service, which aims to end the use of single-use glass bottles. Furthermore, for every ecoTOTE container they sell, 1kg of ocean waste is collected and to date our efforts have contributed to 748 kg’s collected and 3,114 single-use glass bottled avoided. 

In guest rooms, single-use 90ml shampoo, conditioner and hand lotion amenities were replaced with larger  480 ml multiple use bottles and all single use plastics were removed from the rooms.  In room coffee stations include paper cups, paper lids, bamboo stirrers and the espresso machines use recyclable aluminium pods.  

Hotel Sustainability Champion & Assistant Director of Engineering D’Esta Ascento and her team were very focused on energy efficiency and waste management reduction. LED lighting, heat recovery systems, energy management systems, promoting recycling, an in-house reverse osmosis machine, and the ORBISK food waste management systems all came online in 2024. 

Last fall, Hamilton Princess partnered with BE Solar, a Bermudian solar company, to implement a partial solar energy system to offset a portion of the hotel’s energy consumption. At present, the hotel has stopped the use of more than 6,000 barrels of oil from being consumed and prevented over 3,100 metric tonnes of carbon emissions from entering its atmosphere. Also, they are generating enough energy to power 30 guest rooms daily. A total of 245 solar panels were mounted in its first phase, providing clean, renewable energy for at least 30 years, and redefining what sustainable hospitality looks like.

Ms. Ascento said, “General Manager Tim Morrison’s leadership has been a constant source of support, and Director of Operations Roydell Neverson has been key in driving our sustainability initiatives. Sustainability has truly become part of our culture, thanks to the collective effort of our Brand, Hotel ownership and all of the Operational Team. 

“Having this kind of support is essential because change can be challenging,” she continued. “We’re focused on shifting perspectives, creating a more sustainable mind-set for both our guests and our team. When sustainability becomes second nature, new initiatives are embraced with open arms.” 

The feedback to the hotel’s sustainability efforts has been overwhelmingly positive. “It means so much to the ongoing success of our hotel and in our care for our community,” Ms. Ascento reflected, noting the lasting impact of these initiatives.  

The hotel aims to reach net zero by 2050.

Six Marriott International hotels receive Green Key certification in Mexico

On 29 January, Zadún, a Ritz-Carlton Reserve, and Solaz, a Luxury Collection Resort in Los Cabos, received Green Key certification. Additionally, on 6 February, four more hotels—Marriott Puerto Vallarta Resort & Spa, The Westin Resort & Spa Puerto Vallarta, The St. Regis Punta Mita Resort, and Sheraton Buganvilias Resort & Convention Center in Puerto Vallarta—were awarded the certification, bringing the total to six Marriott International hotels in the programme. With these additions, Mexico now has 248 certified hotels.

The hotels have implemented measures focused on the sustainable use of water and energy, as well as proper waste management. Thanks to these actions, they comply with the Green Key International criteria and demonstrate their commitment to the Sustainable Development Goals of the UN 2030 Agenda.

Among the numerous good practices promoted, the following stand out:

  • Solaz, a Luxury Collection Resort in Los Cabos, has a composting project that has produced 351 kg of compost, which is used as organic fertiliser for the soil and green areas.

  • Marriott Puerto Vallarta Resort & Spa has maintained an orchard for five years, using the harvested fruit in its restaurant to ensure zero-kilometre sourcing.

  • The Westin Resort & Spa Puerto Vallarta, Marriott Puerto Vallarta Resort & Spa, and Sheraton Buganvilias Resort & Convention Center simultaneously implement the Blue Flag programme to keep their beaches clean and ensure proper environmental management for their preservation.

These hotels follow in the footsteps of Sheraton Buganvilias Resort & Convention Center, the first Green Key-certified hotel in Mexico. For more than 10 years, this site has continuously worked to meet the certification scheme’s requirements and was also a pioneer in obtaining both Green Key and Blue Flag certifications in the country.

A sincere thank you to Green Key Mexico for its leadership in overseeing the programme at a national level and for its dedicated coordination with Green Key-certified establishments, culminating in the successful achievement of 248 certified establishments as of February 2025.
