Environmental product declarations (EPDs) and product life-cycle assessments (LCAs) are essential for manufacturers of building materials to quantify, report, and reduce the environmental impacts of their products. Selecting the appropriate EPD software ensures compliance with sustainable construction standards — including EN 15804 and PAS 2060, and aligns with Construction Products Regulation (CPR), Ecodesign for Sustainable Products Regulation (ESPR), or regional schemes like BREEAM UK New Construction and Net Zero Carbon Building Framework — while streamlining data collection, modelling, and reporting. Below is a comparison of the leading EPD and product LCA software solutions for 2025, highlighting their product category specialisations, supported standards, and regional scopes.

One Click LCA can help you meet strict emissions regulations by measuring and publishing your product's carbon footprint. The EPD Generator tools enable users to create environmental product declarations for all product categories.
Creating EPDs for an entire product portfolio can be a complex and resource-intensive process. One Click LCA's EPD Generator streamlines this by offering an end-to-end solution that automates EPD creation in compliance with global ISO and EN standards. This tool enables manufacturers to perform product LCAs and generate EPDs across their entire product range efficiently. Features like API integration and automated data handling facilitate seamless incorporation into existing systems, reducing manual effort and minimising errors. By leveraging the EPD Generator, manufacturers can scale their sustainability reporting efforts, ensuring consistent and reliable environmental data across all products.
With 83% of AEC professionals relying on EPDs to select low-carbon materials, having verified EPDs is crucial for manufacturers aiming to maintain and increase visibility in the construction industry. One Click LCA's Manufacturer Pages provide a platform to showcase your products directly to thousands of AEC professionals actively seeking sustainable materials. By claiming your Manufacturer Page in the world's largest construction LCA database, you can consolidate all your products' EPDs and sustainability data into a single, easily accessible location. This organisation simplifies the process for AEC professionals to find, review, and specify your products for their projects, thereby increasing your chances of being selected.
