<aside> 💡 High-Level Description:

The Hotel Carbon Measurement Initiative (HCMI) and the Cornell Hotel Sustainability Benchmarking Index (CHSB) are two prominent methodologies within the hotel industry, specifically tailored to measure carbon footprints and promote sustainable practices. The HCMI, a global standard introduced by leading hotel chains and organizations, focuses on providing a consistent method to calculate and communicate the carbon footprint of hotel stays and meetings. It considers variables like energy and water usage, waste production, and even outsourced services.

On the other hand, the CHSB, pioneered by Cornell University's School of Hotel Administration, serves as an index that allows hotels worldwide to benchmark their energy and water usage, greenhouse gas emissions, and other sustainability metrics against peer institutions. By collating data from diverse geographical regions and hotel sizes, CHSB equips hoteliers with vital insights to improve their environmental efficiency and sustainability credentials, ensuring they remain competitive in an increasingly eco-conscious global market.
