GreenView Hotel Methodology LIVE & SQUAKE Retirement

Overview

The GreenView Hotel Footprinting Tool (HFT) is now fully integrated and available as the preferred methodology for calculating hotel carbon emissions. This transition aligns with industry standards and brings improved accuracy and transparency, leveraging the globally recognized Hotel Carbon Measurement Initiative (HCMI) and Cornell Hotel Sustainability Benchmarking Index (CHSB) datasets.

At the same time, the legacy SQUAKE methodology for hotel carbon calculations will be retired on September 30, 2025. All clients are strongly encouraged to transition their systems to use GreenView or HCMI before this date to ensure continued service and alignment with best practices.

⚠️ After September 30, 2025, the SQUAKE methodology will no longer be available for hotel carbon calculations.
