Lough Eske Castle undertakes sustainability overhaul with eco-conscious initiatives

Lough Eske Castle, Donegal’s only five-star hotel, has taken a significant step forward in sustainable hospitality through a comprehensive suite of eco-conscious initiatives.

Leading the way is the castle’s full transition to renewable energy, achieved through a long-term partnership with a leading green electricity provider. The historic estate is now powered entirely by clean, renewable energy, marking a key milestone in its ongoing commitment to reducing its carbon footprint and aligning with Ireland’s national sustainability goals.

This move to renewable power is just one part of the castle’s broader mission to embed sustainability into every aspect of its operations. With a deep-rooted focus on environmental responsibility, Lough Eske Castle has implemented a variety of impactful changes to enhance its energy efficiency and reduce its carbon footprint.

Among the key upgrades is a complete transformation of the property’s lighting systems, with all fixtures now using low-energy alternatives that have dramatically lowered overall energy consumption. To further improve energy management, Lough Eske Castle is in the process of upgrading its building management system, incorporating both software and hardware enhancements to maximise efficiency throughout the estate.

In the kitchens, the hotel has eliminated its reliance on fossil fuels by replacing gas-fueled cookers with electric alternatives. Water conservation has also been a central focus, with the installation of flow-restriction devices across the property helping to reduce usage. In addition, new rainwater harvesting facilities now collect and repurpose rainwater for the maintenance of the hotel’s extensive gardens.

Preserving the natural environment is a core part of the Castle’s ethos. The hotel has launched an on-site tree planting program and has joined Crann, Ireland’s national tree planting organisation, to support the restoration and protection of native woodlands. Complementing these efforts, wildflower meadows are being cultivated across the grounds to encourage biodiversity and provide a haven for local insects and wildlife.

Further enhancing its environmental contribution, Lough Eske Castle has installed beehives across the estate to protect and support local pollinator populations, species vital to the health of the broader ecosystem. Alongside these efforts, the hotel has introduced a comprehensive recycling program, designed to minimise waste and reduce its contribution to landfills, aligning with its long-term vision for a greener future.

Dónal Cox, General Manager at Lough Eske Castle, says: “We are proud to be rolling out comprehensive sustainability initiatives throughout Lough Eske Castle. Our energy provider partnership is just one example of our ongoing commitment to reducing our environmental impact. We believe it is essential – and expected by our guests – that we deliver an exceptional experience that is both eco-conscious and forward-thinking.”

By investing in renewable energy, protecting local habitats, and embracing innovative waste and water management practices, Lough Eske Castle is setting a new standard in eco-luxury. This historic estate is proving that heritage and sustainability can go hand-in-hand, offering guests the best of both worlds, unparalleled luxury with a conscience. Lough Eske Castle is also proud to take part in Fáilte Ireland’s Climate Action Programme, further strengthening its commitment to sustainable tourism and environmental stewardship.

The five-star Lough Eske Castle is located just outside Donegal Town, nestled within 43-acres of forest woodland hugging the shores of Lough Eske. Boasting 124 spacious guestrooms, including the newly opened Donegal Suites, the Lake Lodge - a private two-bedroom residence and the award-winning CARA Organic Spa.

The award-winning Cedars Restaurant, the Gallery Bar and the Father Browne Bar, Lough Eske Castle are redefining the meaning of luxury and Irish hospitality in the North-West of Ireland.
