Which credit specifically sets VOC limits for carpet cushion?

The correct answer focuses on the intent and requirements of the MR Credit for Material Ingredients, which directly addresses the volatile organic compound (VOC) limits for products used in construction and occupancy, including carpet cushion. This credit aims to promote the use of materials that contain fewer harmful substances and encourages the selection of products that are safer for indoor air quality.

The MR Credit not only sets the criteria for limiting VOCs but also promotes transparency in material composition. This allows project teams to select materials that are less harmful to human health and the environment, particularly those within the indoor spaces of buildings where air quality is paramount.

In contrast, the Indoor Environmental Quality Credit encompasses a broader category related to maintaining a healthy environment within a building, including measures for indoor air quality, but it does not specifically focus on the VOC limits for carpet cushion alone. The Water Efficiency Credit deals primarily with water usage and management, while the Energy Performance Credit focuses on energy efficiency measures and performance. Neither of these two credits addresses VOC limits or material ingredient considerations.
