Stay on top of the latest green business certifications administered by GBCI.

GBCI is the premier global organization for independently recognizing excellence in sustainability performance and practice. With regional offices in the U.S., Canada, Mexico, Europe, India and China, GBCI is accelerating the adoption of green business practices through an array of certification and professional credentialing programs.

With LEED at its core, GBCI offers a suite of complementary solutions for companies to implement sustainability practices across all levels of business. These programs foster global competitiveness and enhance the environmental and human health benefits of our built environment.

Here's a rundown of all the rating systems:

Sustainable SITES Initiative (SITES)

SITES is a comprehensive program for designing and maintaining sustainable landscapes. Land is a crucial part of the built environment, and SITES fills a need for best practices that

  • Reduce water demand and energy consumption.
  • Improve air quality.
  • Create resilient communities that can withstand and recover from catastrophic events.

Landscape professionals can also demonstrate their expertise and commitment to the profession by becoming a SITES AP—a credential that defines the profession of sustainable landscape design and development.

Total Resource Use and Efficiency (TRUE)

The TRUE Zero Waste certification helps businesses and facilities achieve zero waste goals by becoming more resource-efficient and environmentally responsible. Changing how materials flow through society, TRUE ensures that all products are eventually reused and diverted, instead of ending up in the landfill. By closing the loop on waste, facilities can cut greenhouse gas emissions, manage risk, reinvest resources, create jobs and add more value to the business.

GBCI also offers an opportunity to become a recognized zero waste professional through the TRUE Advisor program. TRUE Advisors are trained on the TRUE Zero Waste Rating System and help projects achieve TRUE certification.

  • Reduce operational costs up to 25 percent.
  • Reduce energy consumption.
  • Maximize performance.
  • Minimize waste and harmful emissions.
  • Encourage sustainable transportation, such as ride-sharing and bicycling.

Parksmart projects can also use Arc to benchmark and track building and portfolio performance.

Professionals who are well versed in strategies to reduce the energy and environmental footprint of parking facilities can be recognized through the Parksmart Advisor program.

Performance Excellence in Electricity Renewal (PEER)

PEER is the nation’s first rating system to measure and improve power system performance and electricity delivery. It is designed to improve grid resilience, create greater efficiencies in energy use, reduce carbon and minimize risks caused by poor energy reliability and poor power quality.

From hospitals to municipalities, PEER is transforming the complex power and energy sectors.

Investor Confidence Project (ICP)

ICP is a global underwriting standard for developing and measuring energy efficiency retrofits for commercial and multifamily residential buildings. Through its Investor Ready Energy Efficiency (IREE) certification, ICP aims to standardize energy efficiency upgrades through best practices that make projects more attractive to investors and building owners. These protocols lower transaction costs and increase confidence in savings.

The program was developed by the Environmental Defense Fund and is available in the U.S., Canada and Europe.

GRESB

GRESB is an investor-driven organization committed to assessing the environmental, social and governance (ESG) performance of real assets globally.
