The 411 on Top Green Hotel Certifications
The race continues as hotels strive to one-up their competition. In January we had published an investigative article on green hotel certifications exploring various anglesof “why certify” and details of major certification programs. As the number of green certification programs continues to grow, we want to revisit some of the prominent certifications that continue to lead the hospitality lodging industry on the green trend.
Compared to the beginning of the year, hoteliers have more options than ever when it comes to selecting which green lodging certification program to participate and obtain. From established worldwide green certification programs to the recent state versions, analyzing the options could be overwhelming. The key factor in selecting the appropriate program is to ensure it provides absolute value through quantifiable results (ie. energy usage, cost reduction, guest satisfaction, etc). We recommend our clients to start with a hotel energy benchmarking and tracking system.
Are you in? Standing on the sidelines can cost you money in the long run. While obtaining a green certification is not mandatory, it could mean you are missing out on some great benefits, which include:

- Reduced operating costs
- Improve the bottom line
- Demonstrate leadership in sustainability
- Enhanced reputation, brand and market value
- Federal and state tax benefits
- Reduction of green house emissions
- Attract eco-conscious travelers
- Healthier environment for employees and guests
- Attraction and retraction of talent
There are a variety of green certifications that can denote that a hotel is implementing specific green practices, however each program has a different focus, different priorities and different standards — no two are alike. In a recent article published by Hotel & Leisure Advisors, four aspects have been identified to distinguish the focus of green certification programs: “These broad categories consist of certifications for overall building structures, the building fixtures themselves, building operations, and overall management practices.”
Keeping these categories in mind, the following are top green lodging certification programs (in alphabetical order):
- Audubon Green Leaf™ Eco-Rating Program: (www.greenleaf.auduboninternational.org) This program works with hotels to ensure that they are using green practices in their upkeep and everyday running of the establishment.A tiered certification program where environmental measures are evaluated according to: water quality, water conservation, waste minimization, resource conservation, and energy efficiency.
- EcoRooms® & EcoSuites™: (www.ecorooms.com) Certified properties must meet eight strict eco-criteria for membership and certification. The criteria includes: use of Green Seal certified cleaning and paper products, towel and linen reuse program, recyclable waste program, energy efficient lighting, high efficiency plumbing, and 100% smoke-free properties.
- EPA’s Energy Star label: (www.energystar.gov) The Environmental Protection Agency’s Energy Star program enables buildings to qualify through meeting strict energy performance standards. Energy Star labeled properties use less energy, have reduced operating expenses, and reduced greenhouse gas emissions. To be certified, the property mustattain a minimum score of 75, the top 25%, based on EPA’s National Energy Performance Rating System. As of November 2010, there are 426Energy Star labeled U.S. hotels.
- Green Globe Certification: (www.greenglobecertification.com) This is a certification label for sustainability in both management and operations. Certification criteria cover several areas, including sustainable management and social economic, cultural heritage, and environmental aspects of sustainability.The program’s criteria are also updated annually to ensure international compliance.
- Green Key®: (www.green-key.org) The is an international eco-label for leisure organizations including hotels, conference centers, youth hostels, and campsites. As a graduated rating system, hotels are given guidance on how to “unlock” opportunities to the next level. The program assesses the five main operational areas of a property and covers nine sustainable practices.
- Green Seal certification: (www.greenseal.org) This tiered certification is presented to those lodging properties that achieve various levels of compliance with GS-33, Green Seal Environmental Leadership Standard for Lodging Properties. Properties must demonstrate science-based evaluation of sustainable practices in following areas: waste minimization, energy efficiency, conservation and management, management of fresh water resources, wastewater management, hazardous substances, and environmentally conscious purchasing.
- USGBC LEED® certification: (www.usbgc.org/leed) The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. Promotes a whole-building approach to sustainability by recognizing performance in five key areas: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality.

Energy Usage & Benchmarking
The advancement in lighting technologies now means that there are a spectrum of energy-efficient light bulbs including LED bulbs available to purchase. LED retrofits can offer your green hotel two key benefits: (1) some fixtures can deliver up to 85 percent energy savings and (2) the life span of LEDs average about 50,000 to 100,000 hours, reports Retrofit Magazine. Before making a decision on a retrofit however,
