Trusted by enterprise — loved by teams
“One Click LCA is powerful and easy to use for building LCA. Their continuous improvement is key in facilitating the wide adoption of LCA by the building industry.”
Nikolaos Vlasopoulos
LCA Services Manager
“Carbon Designer 3D is amazing. We can look into options for reducing carbon very early in the design process, when we don’t even know what the material profile will look like.”
Judhajit (Jude) Chakraborty
Senior Sustainability Consultant
“One Click LCA is the quick and easy way. We appreciate the support service from their LCA experts to discuss modeling approaches and finalise EPDs efficiently.”

Frequently asked questions
Learn more about construction LCA with One Click LCA
Can an LCA be done without material quantities?
Is the tool user-friendly for LCA beginners?
Can I optimise cost and carbon in my projects?
How does the tool work if the material manufacturer is unknown?
Does One Click LCA integrate with BIM and other design software?
Yes — One Click LCA integrates seamlessly with the tools you already use in design and construction workflows. Our software offers direct plugins and import features for over 20 industry-standard platforms, ensuring smooth data transfer and minimal duplication.
For Building Information Modelling (BIM), we offer native plugins for Autodesk Revit and Navisworks, and support for open formats like IFC — making it easy to import data from tools such as ArchiCAD, Tekla, or Bentley OpenBuildings Designer. You can also connect through Rhino/Grasshopper for parametric design workflows, or bring in operational energy data from tools like IES-VE using gbXML.
Quantity surveyors and cost consultants can import Excel-based bills of quantities, while APIs enable integration with custom systems or databases. These connections allow you to automate data capture, eliminate manual entry, and focus on what matters: high-quality life-cycle analysis with reliable, standards-compliant results.
Which certifications, standards, and regulations does One Click LCA support?
One Click LCA helps you meet the requirements of over 80 global and regional green building certifications 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.
Does One Click LCA help achieve BREEAM credits?
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.
Is One Click LCA compliant with RICS Whole Life Carbon Assessment guidelines?
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.
How does One Click LCA support future embodied carbon regulations in the UK, like Part Z?
The UK construction sector is preparing for future regulation of embodied carbon — and Part Z is at the forefront of that shift. This proposed amendment to Building Regulations would make whole-life carbon reporting mandatory for all major projects in the UK.
While not yet enforced, local authorities (e.g. London, Manchester) and public sector clients (e.g. NHS, local councils) are already asking for WLC assessments as part of planning or procurement. One Click LCA enables you to deliver these assessments today — using recognised standards like RICS, EN 15978, and BS EN 15804.
The platform is “Part Z ready” — it calculates embodied carbon across all lifecycle stages, applies benchmark comparisons, and adapts to new guidance as it’s published. When regulation does arrive, you’ll already be fluent in the required methods, formats, and outputs.
By adopting One Click LCA now, you future-proof your practice and demonstrate leadership in carbon accountability — long before the rules catch up.
Does One Click LCA include UK-specific material data, like the ICE database or local EPDs?
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.
