# 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.**
