With a growing focus on reducing upfront carbon emissions to more accurately measure the whole life carbon emissions of buildings, EPDs are now essential for architects making more informed material choices. EPDs provide third-party-verified data that supports greener building practices. For Pro Clima, this certification aligns its solutions with international standards such as the IGBC’s Home Performance Index, LEED, BREEAM and the EU’s Sustainable Product Policy. Under the Construction Product Regulation (CPR), environmental data is now mandatory within the EU. By offering verified data, Pro Clima strengthens transparency for whole life carbon assessments and supports informed product specification.

Certified products

Several key Pro Clima products have received EPD certification, including the Intello Plus vapour control membrane, which allows up to one hundred times more moisture vapour to escape compared to conventional vapour control layers (VCLs) with fixed diffusion resistance.

Rather than using generic values for airtightness-sealing accessories, Pro Clima has also published specific EPDs for individual tapes and glues. Niall Crosson, group technical director for UK and Ireland Pro Clima distributor Ecological Building Systems said that the level of detail in the EPDs: “provides even greater transparency and accuracy for carbon assessments. Pro Clima now offer the most comprehensive airtightness system EPD on the market.” Beyond certification, Pro Clima has taken further steps to reduce environmental impact. Its Intello Plus membrane now incorporates 50 per cent recycled content in the fleece layer, the first of its kind in Europe. This innovation cuts virgin plastic use by over 225,000 kg annually, reduces fossil resource demand, and lowers energy consumption during manufacturing — all while maintaining the product’s trusted performance.

“The Irish and UK construction industries are working toward net zero emissions by 2050,” said Crosson, “driving a shift to low-carbon, resource-efficient materials and sustainable design. For nearly 25 years, Ecological Building Systems has supported this transition by promoting natural, lower-impact alternatives to high-embodied carbon materials. Design-stage decisions on materials can have environmental effects lasting decades or more. Understanding the full life-cycle impact of materials helps specifiers reduce upfront emissions in both new-builds and retrofits. Pro Clima’s Environmental Product Declaration (EPD) sets a new standard for airtightness and windtightness systems, uniquely covering not just membranes but also tapes and adhesives. This allows for more accurate carbon footprint calculations and better-informed, sustainable design choices.’’
