We publish our sustainability performance every year — the numbers, not just the intentions. Reports are prepared under Criterion A3.1 of the GSTC Tour Operator Standard and reviewed by our certification body.
← Back to sustainabilityOur first year of systematic environmental monitoring following GSTC certification in September 2025. This report sets the baseline against which every future year is measured — carbon, energy, water, waste, community contributions, supplier assessment and staff training.
Superseded reports stay available so our year-on-year record can be checked. They are kept clearly dated and are not presented as current performance.
2025 is our baseline year and the first report published under this programme, so the archive is currently empty. Each following year will be added here and kept accessible.
The prior year's data is compiled: energy, water, waste, carbon, community contributions, staff training, customer feedback and corrective actions.
The report is prepared by our COO and Sustainability Coordinator and approved by the Managing Director.
The approved report is published here and clearly marked as current. It is also available to any interested stakeholder on request at any time.
After any change to this website we re-check that the latest report is reachable, correctly dated and clearly marked as current.
Partners carrying out supply-chain due diligence, and anyone else who wants the underlying data, can write to us directly. We can provide our certification documentation and the supporting evidence behind the figures in these reports.
