NCIDQ IDFX Practice Exam 2026 - Free Interior Design Fundamentals Exam Practice Questions and Study Guide

B is the correct answer because Greenguard is a well-recognized organization that focuses specifically on indoor air quality and the emissions of indoor products. It provides certification for products that meet strict chemical emissions limits, which help reduce indoor air pollution and improve the overall health of indoor environments. Greenguard certified products are tested for emissions of chemicals over time to ensure they contribute positively to indoor air quality.

The other organizations listed have different focuses. The Collaborative for High Performance Schools primarily promotes and shares best practices for designing and constructing schools that support better learning environments through sustainability. The Green Building Initiative offers resources for green building initiatives but does not specifically focus on indoor emissions certification. The Forest Stewardship Council is focused on sustainable forestry and the responsible management of forest resources, influencing timber products but not directly measuring indoor emissions. This distinction highlights why Greenguard is the appropriate choice for the question regarding indoor product emissions certification.
