Hotel Green Policy & Sustainability Practices

In August 2025 the hotel was recognised for its efforts in energy management and carbon reduction with ISO 50001 certification. This is internationally recognised standard that provides a comprehensive framework for organisations to establish, implement, maintain, and continually improve energy performance. It focuses on enhancing energy efficiency, optimising usage, reducing consumption, and ultimately lowering environmental impact. This milestone on our sustainability journey underscores our commitment to reducing our carbon footprint and maximising the environmental impact of our operations as we continue to drive more meaningful progress towards a more sustainable future

Waste performance
Waste performance shows a particularly strong improvement in 2025, especially in relation to waste sent to landfill or incineration. Compared with the 2018 baseline, landfill/incineration waste reduced from 459,147 litres to 168,300 litres, a reduction of approximately 63.3%.
Compared with 2024, landfill/incineration waste reduced from 453,478 litres to 168,300 litres (-62.9%). Organic waste also reduced from 73,640 litres in 2024 to 69,300 litres in 2025 (-5.9%). Recyclable waste increased from 376,573 litres to 407,171 litres (+8.1%), which is positive where it reflects improved segregation and diversion away from disposal.
Overall, the 2025 data indicates a major improvement in waste management, with substantially less waste being sent to landfill or incineration.

LPG & Oil
Between 2023 and 2025, LPG consumption reduced from 1,236,607 kWh to 1,050,284 kWh, a decrease of 186,323 kWh, or approximately 15.1%.
LPG is the hotel’s main heating source and replaced oil in 2019, which was a more carbon-intensive fuel source. The hotel plans to reduce its reliance on fossil fuels by investing in heat pumps over the coming years and by reducing heating energy demand through investment in more energy-efficient equipment.
