Sustainability: Both an Ethical Imperative and a Competitive Advantage

In 2026, sustainability is no longer just a "marketing slogan" — it's a genuine guest expectation. Research shows that 78% of travelers prefer eco-friendly hotels, and 65% are willing to pay more for sustainable accommodations.

At the same time, sustainability practices lead to significant cost savings. Improvements in energy, water, and waste management can save a mid-sized hotel TL 200,000-500,000 annually. Thus, sustainability means both doing the right thing and boosting profitability.

Marketing Strategy

Create a sustainability page (website)
Display your certifications on OTA profiles
