The intention of the MAT-1 credit is to ensure that building materials are sourced and produced responsibly with a low impact on the environment over their lifetime. The intention of MAT-2 is to minimise use of VOCs. The use of eco labels as a reference is a way of ensuring that this is the case with materials used on a project. Therefore, where a manufacturer of products that have an eco-label produces another model in the same range without official certification but using the same materials and under the same conditions as the product with an eco-label, it is likely to have as low an environmental or health impact. Therefore, if the manufacturer can confirm that a product is made with the same materials and under the same conditions as another product in the same range with an eco-label, this product will be awarded the same points.
