A Greener Future at Four Seasons Hotels Istanbul

Four Seasons Hotels Istanbul is redefining what it means to experience luxury. With sustainability at its core, the brand is blending world-class hospitality with environmentally conscious practices, ensuring that indulgence today helps protect tomorrow.

With two iconic properties, one overlooking the shimmering waters of the Bosphoraus and the other nestled in the historic heart of the Old City, Four Seasons Hotels Istanbul continues to set new standards by weaving sustainability into every detail of the guest journey.

Sustainable Practices with Impact

At the heart of this vision is a commitment to reduce environmental impact while enhancing the guest experience. Both Four Seasons Hotel Sultanahmet and Four Seasons Hotel Bosphorus have eliminated single-use plastics, replacing them with refillable amenities and glass bottles. On-site water filtration and bottling facilities not only provide guests with premium drinking water but also significantly cut the hotels’ carbon footprint.

The kitchens employ artificial intelligence to measure and minimize food waste, while 70 percent of all ingredients are sourced from local producers, strengthening the regional economy and bringing seasonal authenticity to the table. Across both properties, energy efficiency measures, from LED lighting to water pressure optimization, have reduced water consumption by 42 percent. Even the smallest details are considered: straws at Four Seasons Hotel Bosphorus are made from recycled coffee grounds, offering a refined yet innovative alternative to plastic.

A Team-Driven Commitment

Sustainability at Four Seasons Hotels Istanbul is as much about people as it is about operations. Spa therapists work with natural massage oils created by women entrepreneurs. Bars transform fruit peels into cocktail garnishes and extracts, proving that creativity can drive waste reduction.

The culinary team brings the philosophy to life in every dish. At Bosphorus, Executive Chef Görkem Özkan and Executive Sous Chef Alper Kızılbayır champion responsible fishing by sourcing MSC and ASC certified seafood. At Sultanahmet, Chef Özgür Üstün emphasizes seasonal produce and enhances his menus with herbs grown in the hotel’s own garden. Collectively, the team ensures that sustainability is woven into the guest experience in a way that feels effortless and authentic.

Leading at a Global Level

These efforts have positioned Four Seasons Hotels Istanbul at the forefront of international sustainability benchmarks. The hotels have earned the prestigious GSTC Stage 3 Certification, meeting the highest standards in sustainable tourism. The year 2025 also brought the Forbes Verified Responsible Hospitality Certification, a recognition that underlines the hotels’ commitment to ethical and eco-conscious luxury.

Alongside sustainability, health and safety remain non-negotiable priorities. Through the Lead With Care (LWC) program, Four Seasons Hotels Istanbul continues to deliver the highest levels of well-being for guests and employees alike.

Looking Ahead

By pairing unforgettable guest experiences with a forward-looking sustainability vision, Four Seasons Hotels Istanbul is showing that true luxury is not only about excellence in service but also about caring for the world we share. The result is hospitality that feels indulgent, responsible, and above all, future-ready.
