The Westin Yokohama Achieves International Eco-Label 'Green Key' for Second Consecutive Year

The Westin Yokohama, a lifestyle hotel embodying the new era of 'well-being,' is proud to announce that it has once again received the international eco-certification program 'Green Key,' following its initial certification in 2025. This prestigious recognition is awarded to hotels and tourism facilities that demonstrate exceptional environmental responsibility.

'Green Key' is a globally recognized certification granted to facilities that meet strict international standards for environmental conservation and sustainable operations. This renewal reflects the continued recognition of The Westin Yokohama’s comprehensive sustainability initiatives, including reducing environmental impact, contributing to the local community, and providing sustainability education for employees.

At The Westin Yokohama, we are committed to the brand’s core well-being principles of 'Eat Well,' 'Sleep Well,' and 'Move Well,' while aligning with Marriott International’s ESG strategy, 'Serve 360.' Since opening, we have actively implemented initiatives aimed at reducing environmental impact and contributing to the local community. We strive to provide guests with a restorative stay while operating in a manner that respects both the environment and society. As the only Green Key certified hotel in Kanagawa Prefecture, we will continue our efforts toward a sustainable future.

Key Initiatives for Sustainable Hotel Operations

The Westin Yokohama is advancing various initiatives in line with the Green Key certification criteria to reduce environmental impact and contribute to the local community. Below are some of our representative efforts:

Local and Sustainable Sourcing

We actively source local ingredients, including those from Kanagawa Prefecture, as well as seasonal produce. We also promote the procurement of environmentally and socially responsible products, such as those with organic, eco-label, and Fair Trade certifications.

Elimination of Plastic Bottles

We have installed an on-site bottling facility equipped with a state-of-the-art water purification system, offering drinking water in recyclable glass bottles. By minimizing the use of single-use plastic bottles, we are working to reduce plastic waste and promote resource circulation.

Reducing Environmental Impact

We continuously monitor energy and water usage throughout the hotel, actively promoting energy efficiency and water conservation to minimize the environmental footprint of our operations.

Waste and Food Loss Reduction

We are committed to minimizing waste generation and actively promoting reuse and recycling. Additionally, through proper inventory management and thoughtful service methods, we are reducing food waste.

Promotion of Environmental Conservation Activities

We contribute to building a sustainable local community by participating in regional community and environmental conservation activities, providing sustainability education for employees, and raising environmental awareness among our guests.
