Hotel: GreenView

💡 High-Level Description

The GreenView Hotel Footprinting Tool (HFT) is a robust, industry-recognized dataset that provides carbon footprint coefficients for hotel stays and meeting spaces worldwide. It is based on the Cornell Hotel Sustainability Benchmarking Index (CHSB) data, offering more granularity and updated figures.

The GreenView HFT dataset:

• Covers ~200 countries, 100 sub-national regions, and 450 market areas.

• Includes coefficients segmented by hotel star rating (2–5 stars) and hotel average.

• Is updated annually and adapted from the latest CHSB dataset.

• Is intended for integration into hotel emissions calculations and sustainability reporting.

GreenView HFT enables Online Booking Tools (OBTs), Travel Management Companies (TMCs), Online Travel Agencies (OTAs), and other stakeholders to calculate and communicate hotel emissions with improved accuracy and transparency.

Default Logic

📍 Location hierarchy

1. If city data is unavailable → fallback to state.

2. If state data is unavailable → fallback to country.

3. If country data is unavailable → fallback to continent.

⭐ Stars fallback

1. If data for specified stars is unavailable → fallback to hotel_average.

2. If no stars are passed → use hotel_average.

3. If no location is known → default to 32.69 kgCO₂e per night.
