Our ambition for our Catnic manufacturing site, at Caerphilly, is to be Net Zero Carbon by 2030

We're switching our electricity supply to 100% renewable sources in 2023, and eliminating natural gas usage onsite by investing in electrification of our plant, take full advantage of the decarbonisation of the electricity grid. And we're pushing further with continued investment in the best available technology plant and machinery to minimise energy use, whilst continuing to minimise offsite transport emissions to customers by maximising volume usage in our trailers, utilising transport hubs for distribution of smaller loads, and working with our supply chain to transition to lower carbon fuel alternatives. Plus in 2023 we aim to achieve accreditation to ISO50001 – Energy management accreditation including implementation of energy efficiency continuous improvement measures

Environmental impact information

Product specific type III EPDs have been produced for our lintels to support our customers in their product selection

The environmental impact of products can be assessed using standards such as BS EN 15804, using environmental product declarations (EPDs). EPDs contain information covering some or all stages of the product life cycle from raw material extraction, manufacture and fabrication, to use and end-of-life. In addition to quantified environmental information, an EPD contains a description of the manufacturing route, and a technical description of the product.

To supplement Catnic’s seven individual lintel EPDs we have developed a tool, that has been independently verified according to ISO 14025, to produce Product Environmental Datasheets (PED) for any standard lintel at any manufactured length. To request a copy of a PED for a specific lintel at a specific lintel please contact
