Green Key Global is a leader in environmental certification with more than 3,000 members, offering a set of programs and resources designed specifically for the hospitality industry. For more than 15 years after its flagship program, the Green Key Eco-Rating Program, has been evaluating and certifying hotel properties within their sustainable initiatives. In support of this, Green Key Global simultaneously educates members about the value of these initiatives to environmental, social and economic level through a variety of resources and associations. The Eco-Rating and green programs allow participants to benefit in several ways: cost savings , increased bookings from potential guests who are environmentally conscious , tour operators and event planners, as well as all local businesses which are environmentally responsible . This program was designed specifically for the hospitality industry by the Hotel Association of Canada (HAC) and comes under the banner of Green Key Global.

Based on the results of a comprehensive environmental self-assessment, hoteliers are awarded a 1-5 Green Key rating and provided with guidance on how to "unlock" opportunities to become a cutting edge, green lodging property, and reduce environmental impacts and operating costs through reduced utility consumption, employee training, and supply chain management. The program assesses the 5 main operational areas of a property and covers nine areas of sustainable practices:
