To honour Earth Day, all Chatrium properties proudly reaffirmed their commitment to environmental sustainability through a range of meaningful initiatives under the shared theme "Green Leaf People – Planting a Greener Heart for a Sustainable World.

Organised by the respective Sustainability Committees, each property marked the occasion with unique activities that reflected their dedication to responsible hospitality. These included tree planting, candlelight displays in hotel lobbies to shine a light on sustainability, and turning off non-essential lights for one hour. Each activity served as a simple yet powerful gesture to raise awareness and encourage long-term care for the planet.

These Earth Day efforts are part of Chatrium’s ongoing “Think First, Think Earth” program, which reflects the brand’s vision to embed sustainability into every aspect of hospitality. By turning intention into action, Chatrium creates a culture of environmental responsibility that touches both guests and team members.

We are committed to reducing our environmental footprint by investing in renewable energy. Solar cell panels installed across selected areas of our properties help convert sunlight into clean electricity, lowering dependence on non renewable sources.

This shift to solar energy supports a significant reduction in greenhouse gas emissions, decreases long term energy costs and aligns with global efforts to combat climate change. It is a visible and powerful step in our Think First Think Earth philosophy.

Every ray captured is a move toward a more sustainable and self sufficient future.

Smart Building Management for a Sustainable Future

Aligned with the “Think First, Think Earth” commitment, Chatrium Hospitality is introducing intelligent Building Management Systems (BMS) across select properties. These systems allow for real-time monitoring and control of utilities, helping to optimise energy consumption, reduce greenhouse gas emissions and support preventive maintenance.By analysing data across lighting, air-conditioning and water systems, BMS technology ensures that energy is used only when necessary—maximising operational efficiency while minimising environmental impact. This innovation is a key part of Chatrium’s long-term strategy to embed sustainability into every layer of hotel operations, delivering responsible luxury without compromise.

Our saltwater pools offer a cleaner, more natural swimming experience while reducing the need for harsh chemicals. By using salt instead of traditional chlorine, we create a gentler environment for both skin and the planet.Saltwater systems require less chemical maintenance and produce fewer byproducts, supporting healthier air and water quality around the pool. This thoughtful choice reflects our Think First Think Earth philosophy, where guest wellbeing and environmental care go hand in hand. Swim in comfort. Swim with purpose.

At Chatrium Hospitality, we believe that sustainability thrives when simple habits become second nature. That is why we provide clearly marked recycle bins in guest areas and back-of-house spaces to support proper waste separation of recyclable materials and paper.From water bottles to takeaway packaging and office paper, each item sorted correctly helps reduce landfill volume, conserve resources and lower our environmental footprint. Aligned with our Think First Think Earth philosophy, these bins are more than containers.

They are part of a thoughtful system designed to inspire mindfulness and action among guests and team members alike.Because when we sort with care, we shape a future that is cleaner, smarter and more sustainable for all.

Cleanliness is essential, but how we achieve it matters just as much. Across our kitchens, housekeeping and laundry operations, we use Ecolab chemical solutions that prioritise safety, efficiency and environmental care.

Formulated for high performance, these products help reduce water and energy use while maintaining hygiene excellence. Ecolab’s smart packaging design further supports sustainability goals through concentrated formulas, reduced plastic use and improved recyclability. This commitment to cleaner operations reflects our Think First Think Earth philosophy, where every product, process and package is chosen with purpose.

From welcome notes to in-room guides, the printed materials guests see and touch are created with intention. Using recycled paper for all guest-facing collaterals helps reduce environmental impact while maintaining the elegance and clarity our guests expect.This simple choice supports sustainable resource use, reduces waste and reflects our commitment to thoughtful hospitality. Each piece is carefully crafted to align with our Think First Think Earth philosophy, where even printed communication becomes a part of our environmental journey.Sustainability is not just in what we say. It is in how we choose to say it.

We believe that waste is not the end of the story. Through our partnership with Corsair, a sustainability innovator in advanced recycling, we ensure that separated plastic waste is given a second life.Corsair collects non recyclable plastic materials and converts them into bio oil, a cleaner energy source that supports the reduction of fossil fuel use. This process diverts waste from landfills and contributes to a more circular economy.
As part of our Think First Think Earth philosophy, this partnership reflects our ongoing commitment to smarter waste management, resource recovery and meaningful environmental progress.Sustainability is not just about reducing impact. It is about reimagining what waste can become. Learn more at corsairgroup.com

Digital tools play an important role in our journey toward more sustainable operations. By shifting to online storage for documents, notes and files, we reduce the need for printed materials and lower our overall environmental impact.Cloud based systems help streamline collaboration, improve accessibility and eliminate unnecessary paper waste. Information can be shared, updated and retrieved in real time without relying on physical copies or storage space.This simple yet effective change reflects our Think First Think Earth philosophy, where technology supports both operational excellence and environmental care.

At Chatrium Grand Bangkok, every property features an intelligent Guest Room Management System that blends comfort, efficiency and automation. This system integrates advanced HVAC and lighting control with real-time sensor technology to ensure a consistently pleasant environment for our guests while promoting energy conservation.

Each guest room includes

PIR Motion Sensors
These detect human presence by comparing temperature differences between moving guests and the ambient space. When motion is detected, the lighting and air-conditioning systems are activated or maintained to deliver a welcoming atmosphere.

Magnetic Door Sensors
These monitor whether the guest room door is open or closed. When the door is opened and then closed, the system responds by activating Welcome Mode. Lighting turns on and the air-conditioning is restored to guest-friendly settings.

System Functionality
Unoccupied Mode
When no motion is detected for more than ten minutes, the system enters an energy-saving state. Lights are turned off and the air-conditioning is adjusted to a higher temperature with reduced fan speed to conserve energy.

Occupied Mode
When a guest enters and closes the door, the system activates lighting and sets the air-conditioning to a comfortable temperature. Any motion or interaction with in-room switches or the thermostat resets the internal timer to ensure continuous comfort. If the room remains inactive for ten minutes, the system returns to energy-saving settings but will immediately resume full function when movement is detected again.

This intelligent automation is part of our commitment to gracious living and mindful hospitality, providing a refined experience that is both comfortable and sustainable.

At Chatrium Grand Bangkok, innovation meets responsibility. With the introduction of Aiello, our in-room voice AI assistant, we are reimagining luxury to be not only seamless and personalised, but also environmentally conscious.Aiello allows guests to control room settings, request services and access hotel information — all hands-free and paperless. By reducing the need for printed materials and minimising unnecessary energy use, this smart assistant helps us lower our carbon footprint while enhancing guest comfort.From turning off lights with a simple voice command to requesting amenities without a phone call, Aiello supports more efficient operations and a quieter, greener stay.
