Environmental Product Declarations
From material extraction to recycling, we are completely aware of the environmental impact of our products. Our environmental product declarations ensure that you can be too.

EPDs are comprehensive reports that provide transparent information about a product's environmental impact over its entire lifecycle
From raw material extraction to disposal. As sustainability becomes a priority for businesses and governments, EPDs are increasingly essential for informed decision-making.
While not yet legally required, the demand for EPDs is growing, particularly in the construction industry, a major contributor to global carbon emissions, raw material use, and waste. EPDs drive transparency, helping businesses reduce environmental impact and enabling people in the construction process to make more sustainable choices.
To help us to understand, monitor and mitigate our impact on the environment, we turned to construction industry experts: Institute Bauen and Umwelt (IBU) to conduct a full life cycle assessment of the Simpson Strong-Tie manufactured ranges of connectors, screws and nails.
The outcome is a suite of environmental product declarations which conform to the European standard EN 15804, with published values that can be incorporated into the sustainability assement of building projects.
