The Green Building Council is an organization that promotes sustainable building practices. It focuses on improving the environmental performance of buildings through guidelines and certifications. The council encourages the use of eco-friendly materials, energy efficiency, and water conservation in construction and renovation projects. One of the council's key initiatives is the LEED (Leadership in Energy and Environmental Design) certification program. This program provides a framework for assessing the sustainability of buildings and helps architects, builders, and developers create healthier and more efficient spaces. By promoting these practices, the council aims to reduce the overall impact of buildings on the environment.
