Currently available resources
The following described resources created by WSHA empower and support hotels to embrace responsible operations and pursue sustainable growth.
The Hotel Carbon Measurement Initiative (HCMI)
The HCMI is one of the publicly accessible calculation tools offered by WSHA. It is currently utilized by more than 30,000 hotels worldwide. The HCMI tool aims to assist businesses in the hospitality industry in understanding the carbon footprint and energy consumption associated with meetings and hotel stays on their premises.
Since 1990, global CO2 emissions have risen by nearly 50%, and the hotel sector is responsible for 1% of these global carbon emissions. The hospitality industry, like other sectors and people around the world, faces the consequences of extreme weather events occurring worldwide.
The HCMI tool proves valuable for hotel companies in comprehending and managing their environmental impact.

The Hotel Water Measurement Initiative (HWMI)
The HWMI is another publicly accessible tool provided by SHA. It is currently employed by over 18,000 hotels globally. This tool aids businesses in understanding and calculating their water usage.
Water scarcity affects more than 40% of the global population. On average, hotels consume 1,500 liters (approximately 396.26 gallons) of water/room/day, often exceeding the water consumption of local populations in regions with water scarcity. Consequently, hotels bear a significant responsibility in managing their water usage and minimizing their negative impact.

The Hotel Waste Measurement Methodology (HWMM)
The Hotel Waste Measurement Methodology is also available to businesses and primarily targets hotel portfolio managers, although individual properties can also benefit from it. This methodology assists in defining inventory boundaries, measuring and reporting generated waste, and addressing waste-related challenges in the hospitality industry. Establishing a common approach to measuring impact and tracking progress is crucial in addressing waste as a significant issue.

The Net Zero Methodology for Hotels
The Net Zero Methodology for Hotels aims to provide support to the hotel industry in committing to and working towards achieving net-zero emissions. It helps with baseline setting, creating emissions boundaries, planning a pathway and milestones to achieve net zero, and providing an understanding of the effect of the hotel’s emissions on real estate and tourism value chains.
