ISO 14064-1 is an international standard developed by the International Organization for Standardization (ISO) that provides a framework for measuring, reporting, and verifying greenhouse gas (GHG) emissions. It is part of the broader ISO 14000 family of environmental management standards and is designed to support sustainability efforts across various industries.
The Green Squared certificate is a sustainability certification for tiles and tile installation materials, developed by the Tile Council of North America (TCNA). It ensures products meet the rigorous sustainability criteria of the ANSI A138.1 standard, covering aspects like product characteristics, manufacturing, and end-of-life management.
The Greenguard Gold Certification ensures that products intended for indoor use are characterized by practically non-existent emissions of volatile substances, contributing to the creation of healthier environments. Greenguard Gold Certification considers safety factors essential to guarantee the best quality for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and health care facilities. This certification is widely recognized and accepted by sustainable building projects and housing regulations worldwide. In the United States, it is referenced by The Collaborative for High Performance Schools (CHPS) and the Leadership in Energy and Environmental Design (LEED) building rating systems.
Leed Certification (Leadership in Energy and Environmental Design) is one of the most popular green building certification programs used worldwide, being recognized and active in more than 40 countries. It includes the evaluation and certification of the environmental, social and economic sustainability using a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods.
According to LEED classification criteria, building materials with high Eco-sustainability contribute to obtaining credits by raising the building’s score. LEED certifies that all the slabs contain recycled material in accordance with ISO 14021, thus guaranteeing high scores according to the LEED system, which aims to help building owners and operators be environmentally responsible and use resources effectively.
