When it comes to sustainability certifications, not all labels are created equal. GlobalGreen ag, one of the world’s most trusted eco labels, offers a range of accreditations that assess different aspects of a product’s environmental, health, and ethical performance. These certifications go far beyond marketing—they require rigorous third-party verification across a variety of criteria, from life cycle impact to chemical transparency.

At Weathertex, every cladding product is assessed across multiple Global GreenTag programs. Below is a breakdown of these certifications, including our independently verified Environmental Product Declarations (EPDs), which add another layer of transparency to our environmental profile.
