Sustainability in Hospitality: How Green Choice Saves Resources and CO₂

3.3 kg CO₂, 23 liters of water, and 4.5 kWh of electricity per cleaning saved. Here's how Green Choice makes hotel sustainability measurable.
Why sustainability in hotels is no longer a nice-to-have
Sustainability in hospitality has long stopped being a marketing trend. Guests expect it, investors evaluate it, and regulations such as the EU Taxonomy make it mandatory. But where to start? Housekeeping is one of the areas where hotels can achieve measurable results with relatively little effort.
The ecological footprint of housekeeping
A single room cleaning uses on average 40 to 60 liters of water — for floor cleaning, bathrooms, laundry, and refilling dispenser systems. Add to that 0.5 to 1.5 kilowatt-hours of electricity for vacuum cleaners, laundry, and hot water. And chemical cleaning agents that end up in wastewater and the environment.
For a 100-room hotel with 75 percent occupancy and daily cleaning of every room, that adds up to roughly 1.3 million liters of water and over 25,000 kilowatt-hours of electricity per year — for housekeeping alone.
Green Choice as a measurable sustainability measure
This is where Green Choice comes in. When guests get the option to skip daily cleaning, resource consumption drops immediately and measurably. A&O Hostels proved this in a two-month trial: 10,000 opted-out cleanings led to savings of 75,000 liters of water, 708 kilowatt-hours of electricity, and 20,000 trash bags.
What's special: these figures are not projections but measured values. Green Choice thus delivers exactly the solid data hotels need for ESG reporting and sustainability communication.
Green Choice Forest: reforestation as a bonus
In addition to direct savings, Green Choice can support a hotel's sustainability communication, for example via the Green Choice Forest. The reforestation project on Mindanao offers a triple benefit: CO₂ sequestration through growing mangroves, natural storm protection for coastal communities, and full-time jobs for the local population.
From a single measure to a strategy
Green Choice is an ideal entry point, but sustainability in a hotel requires a holistic approach. Combine cleaning opt-outs with other measures: LED lighting, water-saving fixtures, local suppliers, waste reduction. The advantage of digital solutions like Green Choice: they provide data that makes progress visible.
Conclusion: sustainability that pays off
Sustainability in a hotel often starts with housekeeping. Green Choice offers a solution that delivers measurable ecological results, cuts costs, and improves the guest experience. No other single measure combines these three aspects as effectively.
Frequently asked questions
How much water does Green Choice save per cleaning?
Based on our current calculation model, a saved room cleaning saves on average around 23 liters of water. In addition, roughly 3.3 kg of CO₂ and 4.5 kWh of electricity are avoided.
Can Green Choice be used for ESG reporting?
Yes. Green Choice provides measured data on saved cleanings, water, energy, and CO₂, which can feed directly into sustainability reports.
What is the Green Choice Forest?
A reforestation project in the Philippines that is supported with 0.50 euros for every opted-out room cleaning. Mangrove forests are planted that sequester CO₂ and create local jobs.
