One Click LCA: EPD and LCA services snapshot
Manufacturers shopping for LCA and EPD help often face a simple fork in the road: software-led workflows that your team must feed with data, or white‑glove services that remove the lift. Here is what One Click LCA offers, where they tend to operate, and what to watch for if you are weighing them against other EPD practitioners.
What One Click LCA provides
One Click LCA positions itself as a software‑first route to product LCAs and EPDs for manufacturers, with optional consulting support. Their public pages highlight an EPD Generator for manufacturing and category‑specific tools, for example concrete publishing with NRMCA. See their service pages for details: EPD Generator for manufacturing and LCAs (oneclicklca.com) and Concrete EPD Generator (oneclicklca.com).
They also offer paid “consulting packs” that add training, template setup, pre‑verification checks, and onboarding for various program operators. You can find that menu here: Consulting Services overview (help.oneclicklca.com).
Scale and throughput at a glance
Based on our analysis as of December 2025, One Click LCA has supported 358 published EPDs for manufacturers in total, with 124 issued in the past year. That output places them among the higher‑throughput developer outfits in the construction products space.
Product categories they touch most
Their EPD work spans about 100 product categories. The heaviest concentrations appear in lighting fixtures (32 EPDs), insulation (18), plumbing piping and windows (15 each), cast decks and underlayment (13), and wood‑related categories such as mass timber and wood flooring. The long tail includes roofing, wall assemblies, aluminum, gypsum, coatings, HVAC, and select MEP components. If your portfolio is highly specialized, check whether a matching Part B PCR exists for your exact product family before you kick off.
How the engagement typically runs
In practice, One Click LCA’s model is software‑led. Manufacturers map bills of materials, utilities, and site data into the tool using spreadsheets, templates, or APIs, then add scenario details and run calculations. Their consulting packs can cover template creation, dataset selection, training, and pre‑checks, which helps but still expects meaningful internal effort for data prep and iteration. Teams who prefer a minimal client‑side workload should explicitly ask who owns data wrangling and what the weekly time ask on engineering will be.
Timelines and what actually controls them
Many providers quote quick LCA modeling once data is clean. The gating factor is rarely the math. It is third‑party verification capacity at the chosen program operator and the rework loop that follows. For example, IBU currently advises that verification alone can take about six months due to market demand and limited verifier availability, even though the ideal is eight weeks (IBU, 2025) (IBU, 2025). EPDs are typically valid for five years, and most PCRs follow a five‑year refresh cadence, so plan your renewal runway early to avoid crunches (UL Solutions, 2024) (UL Solutions, 2024).
Also worth budgeting for: several operators adjusted fees in 2025 to reflect higher verification costs and verifier scarcity, which can influence where and when you publish an EPD, especially at portfolio scale (IBU, 2025) (IBU, 2025).
Where they most often compete
When manufacturers compare choices, One Click LCA often shows up alongside mid‑to‑large EPD developers and software consultancies with global or trans‑Atlantic footprints. Typical peers include WAP Sustainability, Sphera Consulting, PRé Sustainability, and GreenDelta. Regional full‑service consultancies such as Anthesis or engineering‑backed teams are also common comparison points. All can deliver conformant LCAs and EPDs. The practical difference is the client‑side time burden, the smoothness of data intake, and how quickly verification hurdles are cleared.
Fit signals we see from manufacturers
One Click LCA tends to fit teams that want a configurable tool, plan to create many similar EPDs over time, and have staff who can adapt to templates or build light integrations. It is less ideal if your internal bandwidth is tight, your data is scattered across plants and ERP instances, or you want near‑zero friction on data collection and program‑operator coordination. If speed to a verified EPD is mission‑critical, ask for a detailed critical path that covers verification queue times, rework cycles, and who fixes data issues when they surface. Dont leave those assumptions vague.
Questions to ask before you decide
Ask any provider, including One Click LCA, to show a sample data intake for one of your products, the expected weekly time ask by role, and a realistic verification timeline at your target operator. Confirm whether they will triage data gaps for you, or whether your engineers must do it. Clarify who owns PCR selection and renewal planning, since most EPDs will need revisiting on a five‑year cadence to stay aligned with evolving rules (UL Solutions, 2024) (UL Solutions, 2024).
Bringing it together
One Click LCA offers a credible, software‑led path to LCAs and EPDs with optional consulting add‑ons, and they have a broad track record across construction categories. The trade‑off to weigh is classic. Tool‑centric workflows can scale once built, yet they usually require your team to adapt to the tool’s data structures and rhythms. Service‑centric workflows reduce internal lift and can shorten the journey to a verified EPD when verification queues are the bottleneck. Pick the path that protects your team’s time and gets you specified more often, not just the path that looks clever on paper.
Frequently Asked Questions
What LCA and EPD services does One Click LCA publicly offer to manufacturers?
A software‑led EPD Generator for manufacturing, category tools such as concrete, and optional consulting packs for onboarding, template setup, and pre‑verification checks. See their EPD Generator and Concrete EPD Generator pages.
Roughly how broad is their category footprint for EPDs?
About 100 product categories, with concentrations in lighting, insulation, piping, windows, decking underlayments, wood products, roofing, and select MEP components.
How large is their recent EPD throughput?
As of December 2025, they have 358 total EPDs with 124 issued in the past year.
What timeline constraints should we plan for regardless of provider?
Third‑party verification queues dominate the schedule. IBU advises verification can take around six months currently due to limited verifier capacity (IBU, 2025). EPD validity is typically five years, and PCRs often refresh on a five‑year cycle (UL Solutions, 2024).
Who are the main competitors often evaluated alongside One Click LCA?
WAP Sustainability, Sphera Consulting, PRé Sustainability, and GreenDelta are frequent peers, with Anthesis and other regional consultancies also appearing in shortlists.
