Get reliable construction LCA
for UK projects

Yes. One Click LCA is officially approved by BRE for BREEAM New Construction Version 7 assessments in the UK and internationally, helping project teams generate LCA results and reporting required to support credits such as Mat 01 or Mat 02.

Yes — One Click LCA is fully compliant with the RICS Whole Life Carbon Assessment for the Built Environment, the UK’s primary guidance for embodied and operational carbon reporting in buildings.

The tool automatically structures results by building elements (e.g. substructure, superstructure, envelope) in line with NRM and UNICLASS classifications. It reports carbon emissions across modules A to D, accommodates the 60-year reference period, and includes key emissions types — including sequestered carbon for timber or biogenic materials.

This ensures your outputs are ready for any planning submission or WLC report — including those required under the London Plan by the Greater London Authority. For early-stage assessments, Carbon Designer 3D provides RICS-aligned insights to support low-carbon decision-making from the concept stage onward.

Whether for planning, client briefs, or internal targets, One Click LCA provides clear, trusted WLC outputs — consistently accepted by UK authorities and design teams.

Yes — One Click LCA includes one of the most comprehensive UK-focused material databases available. It features the widely referenced ICE database for generic materials, alongside thousands of third-party verified EPDs from UK-based manufacturers.

This means you can model your projects using real data for British cement, steel, insulation, plasterboard, glazing, and more — including suppliers like Kingspan, British Gypsum, and others routinely specified in UK construction.

You’ll also benefit from built-in UK grid electricity factors, transport emissions, and end-of-life scenarios reflecting local practices and regulations. This ensures your life-cycle assessments reflect the realities of construction in the UK, not generic European averages.

If a specific product or dataset is missing, you can upload your own, or request our team to add it — typically within days. The result is a more accurate, locally relevant, and credible LCA that UK clients and planning authorities trust.

One Click LCA helps you meet the requirements of over 140 global and regional green building certifications, standards, methods and carbon regulations. It is fully compatible with:

• LEED (including MRc1 LCA credits for LEED v4 and v4.1)

• BREEAM (UK, International, and RFO schemes, aligned with Mat 01/02)

• DGNB, HQE, Green Star, Level(s), and more

For regulatory compliance, the tool supports EN 15978 (the core building LCA standard), and country-specific frameworks like:

• RICS Whole Life Carbon Assessment (UK best practice)

• RE2020 (France’s new embodied carbon regulation)

• Dutch MPG calculation method

• Buy Clean policies in North America (e.g. California and New York)

Whether your goal is a sustainability certification, client brief, planning requirement, or national regulation, One Click LCA provides the tools and outputs to ensure you stay compliant — today and tomorrow.

Yes — One Click LCA is specifically designed to support BREEAM UK New Construction and Refurbishment schemes. It automates the generation of the required Mat 01 life-cycle assessment report, fully aligned with BRE’s methodology, and includes a dedicated BREEAM module to ensure you follow the correct scenarios and calculation stages.

For Mat 01, you’ll receive a detailed breakdown of the building’s environmental impacts and the carbon savings achieved through design optimisations — exactly what assessors need for credit validation. The tool also supports early-stage analysis to help shape low-carbon design from the outset.

For Mat 02, which rewards the use of verified Environmental Product Declarations (EPDs), One Click LCA offers direct access to thousands of UK-relevant EPDs. It helps you demonstrate compliance with minimal effort, summarising EPD use for credit documentation.

For projects targeting innovation credits, enabling the software’s IMPACT-compliant mode aligns the LCA with BRE’s requirements — unlocking the potential for exemplary performance under BREEAM.

The platform supports cradle-to-grave carbon assessment aligned with EN 15978 and ISO 14040/44, covering embodied carbon (A1–A5), use-stage (B4–B7), end-of-life (C1–C4), and benefits beyond the system boundary (D). Operational energy and water impacts can be included where applicable.

Yes. One Click LCA is used globally with data and methods suitable for international standards and certifications (e.g., LEED, DGNB, CEEQUAL, Level(s)), while also addressing specific UK frameworks and reporting needs.

Yes. One Click LCA is the first software tool validated by RICS under the Whole Life Carbon Assessment (WLCA) Software Validation Programme for the RICS WLCA standard (2nd edition), which ensures its workflows align with RICS expectations for whole-life carbon reporting.

UK projects increasingly use LCA to meet net-zero strategies, satisfy planning and certification requirements (e.g., BREEAM v7, RICS Whole Life Carbon), and align with regional policy trends such as the proposed Part Z embodied carbon rules. LCA helps benchmark carbon, evaluate design options, and produce evidence for sustainability reporting.
