GreenGuard
UL Environment's GREENGUARD Certification programme helps manufacturers create - and buyers identify and trust - interior products and materials that have low chemical emissions, improving the quality of the air in which the products are used. All certified products must meet stringent emissions standards, based on established chemical-exposure criteria.
DIBt
Deutsches Institut für Bautechnik. A German authority similar to “Boverket”, sets limitations on emissions from construction products and building elements, to ensure that they're at a safe level for people moving in. German flooring contractors are obliged to use products that are DIBt-approved.
Emicode
This is an industry organisation that measures emissions from flooring installation products, adhesives and building materials. Products classified as “very low emission”, and carrying the GEV label EMICODE® EC1PLUS, offer the best possible assurance against indoor air pollution for a high level of health protection, and environmental compatibility. See the file under DIBt for emicode criteria. EMICODE is a voluntary classification.
