At COMO The Treasury, we are mindful of our impact on the cultures and environments in which we operate. As such, we are committed to reducing our environmental footprint wherever possible, from prioritising seasonal produce across our restaurants and bars, to utilising the latest in-room energy and water saving innovations.
In January 2026, COMO The Treasury received its second consecutive Silver certification from EarthCheck, the world’s leading environmental management and benchmarking system for the travel and tourism industry.
Your sustainable journey with COMO The Treasury begins even before you arrive, as we have thoughtfully designed every touchpoint to minimise environmental impact. This commitment to sustainability continues throughout your stay, from your room and surrounding, to our eco-conscious dining offerings.
Australians are embracing the shift to electric cars. We offer six 11kW charging destination stations as part of our valet parking service to support the change to electric vehicles.
Inspired by the seasonal shift, our flower installations feature over 1,000 individual stems, meticulously composed into a textural mountain of compact floral elements. Most stems are endemic to the region and all have been locally sourced. We partner with local florist Fox and Rabbit, who specialise in native arrangements.
Good food starts with knowing where it comes from. Across COMO The Treasury, more than 90 per cent of what arrives at the table is sourced from Western Australia or Australia.
Our destination dining experience, Wildflower, offers a 93 per cent Western Australian locally sourced menu – the only course not fully from Western Australia is the cheese course, however all cheeses are still Australian.
Wildflower partners with Tucker Bush to incorporate tangy, crunchy and sweet herbs and plants from the West Australian bush into their seasonal menu. From lemon myrtle to saltbush, these native plants have been used by local Aboriginal people for many thousands of years. The Tucker Bush range aims to introduce a truly local flavour into suburban cooking, working with communities who have unique stories to share. All of the plants in the Tucker Bush range play a vital role in our ecosystem, with some species under threat.
At Post Osteria and Bar, all proteins and vegetables are sourced locally, only a small selection of specialty ingredients is imported from Italy, including prosciutto, pasta flour and cheeses, to preserve the authenticity of the Italian dining experience. 83 per cent of the Post menu features local produce from Western Australia or within Australia.
For scallops, we partner with Endeavour Foods, the leading Rottnest Scallops supplier, who deliver fresh scallops on the day of catch from just 19 kilometres off the coast of Perth. Rottnest Island scallops are only harvested during their peak season, traditionally from September to November. Sustainability of fishing is Endeavour Foods’ paramount concern, as so they work in partnership with the Department of Fisheries to survey the scallop population several times per season, and have fitted their nets with escape panels that allow non-target species to swim out.
For mushrooms, our sustainable partners are the Mushroom Guys, who aim to grow produce in conditions as close to the natural environment as possible. Gourmet mushrooms grow naturally on hardwoods, and so the Mushroom Guys blend sustainably-sourced West Australian hardwood sawdust into every one of their mushroom blocks. This hardwood sawdust is a waste stream of the West Australian timber industry; by using locally sourced waste materials, the Mushroom Guys divert almost 30 tonnes of sawdust waste annually. As the farm is located within the Perth metro area, there is also very little energy expenditure associated with transport and deliveries.
99 per cent of our arrival amenities and minibar selections are sourced from Australia – and where possible from Western Australia – with Nespresso being the only exception.
Our coffee roaster, Good Seeds Coffee Roastery, is based in Perth and sources in-season coffee from farms and producers that share our dedication to authenticity, transparency and quality. For tea, we partner with local retailer Teassential, located within the historic State Buildings.
Our guests are part of our sustainability journey, whether that is through reusing towels and linens to conserve water, or making use of our all-natural COMO Shambhala products.
All COMO The Treasury guest rooms are fitted with motion sensors that control the lighting and air conditioning systems, ensuring optimum conservation of our precious resources. We have installed acoustic panels on all room windows which keep the room cool in summer and warm in winter, reducing the need for the air conditioning.
Rooms are also serviced twice a day and bed linens changed every other day. We invite guests to hang any towels to reuse, and appreciate your collaboration in minimising our environmental footprint.
The hotel is also equipped with high-efficiency water heaters, kitchen equipment, refrigeration systems and air conditioners, as well as low-flow energy-efficient toilets, faucets and showerheads.
To reduce our plastic waste, COMO The Treasury has an onsite filtration and bottling system, which produces high-quality, low-impact still water. We do not utilise plastic straws in the hotel, whilst all takeaway packaging is biodegradable, with only wooden utensils offered. We provide locally grown and in-season fruits in each room, with in-room beverages decanted and served in reusable glass jars and bottles.
The COMO Shambhala products and amenities used across our hotel rooms are crafted from high-grade essential oils and all-natural products. They are free from parabens, sodium laurel sulphate, petrochemicals and synthetics, making them environmentally-friendly and sustainable.
From eco-conscious products to innovative waste management, our team work hard behind the scenes to ensure that our cleaning and recycling efforts meet the highest of sustainable standards.
We use cleaning products that are biodegradable and gentle on the environment, and have replaced single-use chemical cleaning products with reusable Fibre technology textiles wherever possible.
We practise single-stream recycling, with materials sorted by our team before being sent for recycling. Across our waste streams, we divert an estimated 54 per cent of waste from landfill each month.
Our cardboard baler was installed in January 2024 and compacts large amounts of cardboard into manageable bales, saving valuable storage space. Reducing the volume of cardboard waste means fewer collections, cutting down on transportation and disposal expenses: we have cut cardboard collection to twice a week instead of daily.
Our bin compactor was also introduced in January 2024. This allows us to compact non-recyclable waste, reducing the number of waste collections and cutting our on-site bins from 20 to 12. Compacting waste keeps it contained, reducing overflow, odours and potential hazards in waste storage areas.
Green waste bins were implemented in 2026 for food scraps, including coffee grounds, to support improved waste segregation and increase the diversion of organic waste from landfill. This initiative helps reduce general waste volumes while encouraging more sustainable waste management practices.
We have partnered with Containers for Change to divert containers through the Western Australia recycling scheme, with proceeds donated to Lifeline in 2025 and Zero2Hero in 2026. Our current goal is to divert 1,500 containers per week. From July 1st 2026, this target will increase as wine bottles are included in the recycling programme.
We work with partners to sponsor local charity events, enabling local organisations to grow and to raise vital funds. We also organise yearly volunteering activities for our employees, supporting Western Australia’s conservation.
We partner with local charities such as MSWA, Lifeline, Breast Cancer Care and Telethon, offering in-kind donations and support of their community efforts.
We donate 100 per cent of our worn linen to the Rotary Club of Hillarys. Sheets, towels, bathmats and pillowcases are distributed to communities in need, helping improve hygiene standards in low-income regions and under-resourced hospitals. Through this initiative, approximately 46 per cent of textile waste is diverted from landfill each year.
COMO The Treasury has always been a place where culture converges. We are proud to extend that spirit through our support of the arts, including partnerships with the Australian Chamber Orchestra and Perth Festival, nurturing the creative life of Perth alongside our culinary and hospitality offering.
We have partnered with local planting groups to support senior volunteers in planting over 400 sedges along the Swan River. This annual team initiative contributes to ongoing conservation efforts across Western Australia, helping to improve local biodiversity.
We are also proud to support the HBF Run for a Reason in 2026. In addition, we continue to work closely with MSWA, supporting the delivery of services, facilities and funding for people living with neurological conditions across Western Australia.
We proudly volunteer in Keep Australia Beautiful’s annual clean-ups, helping ensure a cleaner, greener environment for all.
