   ecoinvent

   A life cycle inventory database with more than 27,000 peer-reviewed datasets, sold by annual licence and readable in most LCA tools.

   8.7overall

   A life cycle inventory database with more than 27,000 peer-reviewed datasets, sold by annual licence and readable in most LCA tools.

   Best forLCA practitioners who need background data accepted by reviewers

   Adoption data

   5,000ecoinvent says more than 5,000 organizations use its life cycle inventory data.

   ecoinvent, Partners (2026): “Over 5,000 leading organizations trust our data.”

   ecoinvent is the answer to the most common LCA data question: which background database should you build on. Version 3.13 holds more than 27,000 peer-reviewed datasets, adds a pharmaceuticals sector and updates textiles, pulp and paper, batteries, electricity, chemicals and construction. Each dataset is linked in three system models, Cut-off, APOS and Consequential, so the same study can follow different allocation rules. The ecoinvent association says over 5,000 organizations trust its data, and the database is sold as annual Single-User, Enterprise, Developer and Educational licences. A newer ecoinvent API lets software teams pull Climate Indicators and GHG Breakdown packages without handling files. The catch is that ecoinvent is not modeling software: sustainability teams still need SimaPro, openLCA, One Click LCA or a similar tool to build product models, and no list price appears on ecoinvent.org. We compared documented features and published prices.

   Strengths

   • +The widest documented background database in this list, with 27,000+ datasets
   • +Readable inside SimaPro, openLCA and other tools in this list, and offered as a premium dataset in Climatiq PCF Pro
   • +Educational multi-user licences are free for universities in low and lower-middle income countries, per openLCA Nexus

   Limitations

   • −It is data, not modeling software: you still need a tool such as SimaPro or openLCA
   • −No price is published on ecoinvent.org; every licence is quoted
   • −Licences are annual subscriptions, so access ends if you stop paying

   Summaryecoinvent is the best LCA database for teams that need peer-reviewed background data because it publishes more than 27,000 datasets in three system models. Pair it with a modeling tool such as SimaPro or openLCA.

2. 2

   SimaPro

   Life cycle assessment software in cloud and desktop editions, now part of the One Click LCA group.

   8.5overall

   Life cycle assessment software in cloud and desktop editions, now part of the One Click LCA group.

   Best forLCA experts and consultants who need full model transparency

   Adoption data

   90SimaPro says industry and academia use its software in more than 90 countries.

   SimaPro, About us (2026): “Today, SimaPro is used by industry and academia in more than 90 countries”

   SimaPro is the long-standing expert tool for product life cycle assessment, with more than 35 years of development and use by industry and academia in more than 90 countries. It gives access to 250k+ datasets and about 40 LCIA methods, and its desktop editions keep the features reviewers ask for: parameter-based models, unit and system libraries, pedigree matrices and Monte Carlo uncertainty analysis. The plan lineup now runs from Cloud Business, with an AI model builder, a company library and SKU-level portfolio coverage, to Desktop Expert and Desktop Power, which adds links to Excel and SQL databases. An Enterprise plan embeds LCA in company systems. SimaPro has been part of the One Click LCA group since 2025. The downside for budgeting is that every plan is sold by quote, and the cloud and desktop editions split features, so check which edition your team needs before a demo. We compared documented features and published prices.

   Strengths

   • +The largest method library documented by a desktop LCA tool here, about 40 LCIA methods
   • +Three plans from cloud collaboration to Power for method developers
   • +Access to ecoinvent 3.12 is included in all SimaPro plans, per SimaPro

   Limitations

   • −No published prices; all three plans say contact us for a quote
   • −Advanced uncertainty and parameter features sit in the desktop editions
   • −Now part of the One Click LCA group, so product roadmaps may converge

   SummarySimaPro is the best LCA software for experienced practitioners because it combines 250k+ datasets, about 40 impact methods and Monte Carlo analysis in one tool. Expect a quote rather than a list price.

3. 3

   One Click LCA

   Cloud LCA and EPD software for construction and manufacturing with 500,000+ LCA and EPD data points.

   8.4overall

   Cloud LCA and EPD software for construction and manufacturing with 500,000+ LCA and EPD data points.

   Best forManufacturers and building teams that need EPDs at scale

   Adoption data

   170One Click LCA says its software is used in more than 170 countries.

   One Click LCA, One Click LCA home page (North America) (2026): “Used in 170+ countries and AI powered, with 500,000+ global up-to-date, verified, supplier-specific, and generic LCA and EPD data points”

   One Click LCA is the cloud platform to look at if your LCA work ends in environmental product declarations. Its North American site says the software is used in 170+ countries and draws on 500,000+ LCA and EPD data points, including supplier-specific EPDs, with 140+ standards and methods and 20+ BIM and other integrations. For manufacturers, the Business plan includes an EPD Generator for local standards and imports from Excel, IFC, SolidWorks and Autodesk Inventor, and it is ISO 27001 certified. The Expert Pack adds Materials Compass benchmarking, customized private datasets, EPD templates and quality and plausibility checkers, and the Power Pack adds unlimited project EPDs. One Click LCA acquired SimaPro and PRé in 2025, so the group now covers both expert modeling and automated EPDs. Pricing is quote-only, and the focus on construction products means consumer goods teams should check sector data during a demo. We compared documented features and published prices.

   Strengths

   • +The largest dataset count published in this list, 500,000+ data points
   • +Used in 170+ countries, the widest reach claimed by any vendor here
   • +Researchers can apply for discounts of up to 50% on most annual plans

   Limitations

   • −No list prices; every plan says request a quote
   • −Strongest in construction products and EPDs, less focused on consumer goods
   • −The data count mixes generic data with supplier EPDs, so coverage varies by sector

   SummaryOne Click LCA is the best choice for manufacturers producing EPDs at volume because it pairs an EPD Generator with 500,000+ data points. Teams outside construction should confirm data coverage first.

4. 4

   openLCA

   Free, open-source desktop LCA software from GreenDelta that works with most major LCA databases.

   8.3overall

   Free, open-source desktop LCA software from GreenDelta that works with most major LCA databases.

   Best forTeams and researchers who want full LCA modeling without a licence fee

   Adoption data

   over a hundred countriesGreenDelta, which develops openLCA, says its customers are in over a hundred countries.

   GreenDelta (openLCA), About openLCA (2026): “not only in Germany, but in over hundred countries around the globe”

   openLCA is the strongest free option for full life cycle assessment. GreenDelta has developed it since 2006, and it runs on Windows, macOS and Linux at no cost, with source code you can change and models you can share. The software covers ISO 14040 and 14067 studies, the GHG Protocol, Environmental Footprint and EN 15804 EPDs, and adds social LCA and life cycle costing. The LCA Collaboration Server, also free, lets several practitioners work on synchronized databases and track each other's changes, and onlineLCA scales calculations for enterprises. Data comes from openLCA Nexus, which mixes free sets such as the US LCA Commons, with more than 10,000 datasets from US agencies, and paid ones such as ecoinvent. The total cost is therefore the database you choose, plus any training or support. GreenDelta does not publish a user count, so the adoption score is conservative. We compared documented features and published prices.

   Strengths

   • +No licence fee for the software or the Collaboration Server
   • +Reads ecoinvent and other major databases, including the US LCA Commons with more than 10,000 datasets
   • +Source code can be modified and models shared freely

   Limitations

   • −Commercial databases such as ecoinvent still cost extra
   • −Support and training are paid services from GreenDelta and partners
   • −GreenDelta publishes no user count, only customers in over a hundred countries

   SummaryopenLCA is the best free LCA software because the desktop tool and its Collaboration Server cost nothing and read ecoinvent and free databases alike. Budget for data and training instead of licences.

   Sphera LCA for Experts

   Expert LCA software, formerly known as GaBi, bundled with Sphera's Managed LCA Content database.

   8.0overall

   Expert LCA software, formerly known as GaBi, bundled with Sphera's Managed LCA Content database.

   Best forLarge manufacturers that want software and proprietary data from one vendor

   Adoption data

   1,500Sphera says more than 1,500 sustainability leaders use its life cycle assessment solutions.

   Sphera, Life Cycle Assessment Software and Data (2026): “Trusted by more than 1,500 sustainability leaders for 30+ years.”

   Sphera LCA for Experts is the software long sold as GaBi, and it remains a default in large manufacturing companies. Sphera says more than 1,500 sustainability leaders rely on its LCA solutions, and the tool ships with access to the Managed LCA Content database of 20,000+ DEKRA-verified datasets plus 1,000 ready models that experts can use or replace with their own. Sphera adds a BOM import tool, a database server for shared libraries and LCA automation packages for chemical, discrete and process manufacturing, which helps when a one-off study turns into hundreds of product footprints. Saint-Gobain uses it to publish EPDs for product families, and Whirlpool used it to find product hotspots. A 45-day free trial is the longest in this list. Prices are not published, and because the core database is Sphera's own, teams that must use ecoinvent should check licensing before buying. We compared documented features and published prices.

   Strengths

   • +Software and a 20,000+ dataset database come from one vendor
   • +Longest free trial in this list at 45 days
   • +Automation add-ons for chemical, discrete and process manufacturing

   Limitations

   • −No published prices
   • −Sphera's datasets are proprietary, so results depend on one data supplier
   • −Desktop-first modeling suits experts more than occasional users

   SummarySphera LCA for Experts is the best choice for large manufacturers that want one vendor for software and data, with 20,000+ DEKRA-verified datasets. Try it free for 45 days before requesting a quote.

   Climatiq

   Product carbon footprint software and API built on a database of over 1 million emission factors.

   7.8overall

   Product carbon footprint software and API built on a database of over 1 million emission factors.

   Best forTeams answering customer PCF requests quickly

   Adoption data

   tens of thousandsClimatiq says tens of thousands of sustainability professionals use its Studio products, APIs and integrations.

   Climatiq, About Us (2026): “Tens of thousands of sustainability professionals use our Studio products, APIs, and integrations with key business platforms including Celonis, Salesforce, Oracle, IFS, and IntegrityNext.”

   Climatiq is not a full LCA suite but fits teams whose real task is answering product carbon footprint requests from customers. Its database holds over 1 million emission factors, and the company says tens of thousands of sustainability professionals use its Studio products, APIs and integrations with Celonis, Salesforce, Oracle, IFS and IntegrityNext. PCF Studio uses AI data gap-filling and a mapping agent to turn a bill of materials into a footprint, and the PCF Pro plan adds 25 fully auditable PCFs, branded exports and ISO 14067 audit documentation, with ecoinvent, IEA and CarbonMinds available as premium datasets. The free Starter plan needs no credit card and covers 5 basic PCFs under a non-commercial licence. The limit is scope: Climatiq covers carbon, so teams that need water, toxicity or the full EF impact set should use SimaPro, openLCA or Sphera. We compared documented features and published prices.

   Strengths

   • +Free Starter plan with 5 basic PCFs and no credit card
   • +An API lets software teams embed PCF calculations
   • +Can add ecoinvent data as a premium dataset

   Limitations

   • −Carbon only: it does not cover the full set of LCA impact categories
   • −Starter is licensed for non-commercial use
   • −Paid plans are priced in EUR on the page we checked

   SummaryClimatiq is the best choice for teams that only need product carbon footprints because PCF Studio maps a BOM to over 1 million emission factors. It does not replace a multi-impact LCA tool.

7. 7

   Ecochain

   LCA automation software for manufacturers producing EPDs and product carbon footprints.

   7.6overall

   LCA automation software for manufacturers producing EPDs and product carbon footprints.

   Best forIndustrial manufacturers footprinting tens to hundreds of products

   Adoption data

   450Ecochain says more than 450 manufacturers use its software and have run more than 2 million LCAs.

   Ecochain, Pricing (2026): “450+ manufacturers worldwide rely on Ecochain for 2M+ LCAs and counting”

   Ecochain is built for manufacturers that need many product footprints rather than one deep study. The company says 450+ manufacturers rely on it and have run more than 2 million LCAs, and its results follow ISO 14040, 14044 and 14067 and EN 15804+A2, so the same model can feed a PCF or an EPD. Plans are sized by product count: Professional covers one user and fewer than 20 products, Business multiple users and fewer than 200 products with a designated customer success manager, and Enterprise 200+ products with SSO and custom APIs and databases. EPD generation, LCA Support Plans and expert services are paid add-ons. Ecochain is B Corp certified and has 15 years in business. All plans are custom priced, and teams that need method development or Monte Carlo analysis will find more depth in SimaPro. We compared documented features and published prices.

   Strengths

   • +Plan tiers map directly to the number of products you need to footprint
   • +More than 2 million LCAs run on the platform, per Ecochain
   • +B Corp certified with 15 years in business

   Limitations

   • −Prices are custom on every plan
   • −Professional is limited to a single user and fewer than 20 products
   • −EPD generation costs extra

   SummaryEcochain is the best choice for manufacturers scaling from a few to hundreds of product footprints because its plans are sized by product count. Ask for EPD generation pricing up front.

   Brightway

   An open-source Python framework for life cycle assessment calculations.

   7.4overall

   An open-source Python framework for life cycle assessment calculations.

   Best forData scientists and researchers scripting LCA in Python

   Brightway is the choice for teams that want LCA as code. Its documentation describes an open-source Python package designed to work with large datasets and run LCA calculations quickly, with a focus on flexibility and performance beyond conventional LCA tools. That makes it useful for scenario analysis, sensitivity runs and prospective LCA that would be slow to click through in a desktop tool. The project says it has a strong user community in academia and growing use among industry and consulting power users. Learning resources include step-by-step tutorials and a JupyterLite live demo that runs in the browser without installing anything. The trade-offs are skills and support: you need Python, there is no vendor support contract, and the project publishes no user count, so its adoption score is conservative. Commercial databases such as ecoinvent are licensed separately. We compared documented features and published prices.

   Strengths

   • +No licence cost
   • +Scriptable, so large scenario and sensitivity runs can be automated
   • +A browser demo lets you try it before installing

   Limitations

   • −Requires Python skills; there is no point-and-click interface in the core package
   • −No vendor support contract; help comes from the community
   • −No published user or customer count

   SummaryBrightway is the best choice for analysts who script LCA in Python because it is free, open source and built for large datasets. Teams without coders should start with openLCA.

   Web-based ecodesign and LCA software for product designers and engineers.

   Best forProduct designers comparing early concepts

   Adoption data

   60Sustainable Minds says industry and education use its software in 600 locations across 60 countries.

   Sustainable Minds, Sustainable Minds home page (2026): “Today used by industry and education 600 locations, 60 countries”

   Sustainable Minds is a web-based tool that pairs ecodesign strategies with life cycle assessment, so product designers can compare concepts before they are locked in. It is the only commercial tool in this list with a published USD price: $169 per user per month, or $1,600 per user per year for 1 to 4 users, with 5 to 10 users priced at $6,000 to $10,000. Educators pay $399 per year and students $59 per semi-annual term. All subscriptions include software, content and data updates, and users can request additions to the SM Dataset. The company says it is used by industry and education in 600 locations across 60 countries, and it also runs a Transparency Report program for building products. The free trial is short at 1 day, and the tool targets comparative concept work rather than reviewer-grade ISO studies, so expert teams will outgrow it. We compared documented features and published prices.

   Strengths

   • +The only commercial tool here with a published USD price, $169 per month
   • +Annual plan of $1,600 per user for 1 to 4 users
   • +Student subscriptions cost $59 per semi-annual term

   Limitations

   • −The free trial lasts only 1 day
   • −Aimed at early design comparisons rather than full ISO studies
   • −Smaller footprint than the leaders, 600 locations in 60 countries

   SummarySustainable Minds is the best choice for designers who need predictable costs because it lists $169 per user per month. Expert LCA teams will want SimaPro or openLCA.

10. 10

    Tally

    An Autodesk Revit app that runs whole-building LCA on a design model.

    6.7overall

    An Autodesk Revit app that runs whole-building LCA on a design model.

    Best forArchitects modeling buildings in Revit

    Tally is a narrow tool with a clear job: whole-building life cycle assessment inside Autodesk Revit. Architects and engineers link Revit elements to materials in the Tally database and get embodied impact results for the whole building, or compare two or more design options side by side, without leaving the model. It supports Revit 2021 through 2026. Pricing is published in USD: a floating Basic licence costs $695 per year and a Premium licence $995 per year, after a 10-day free trial, and educational licences exist for non-commercial use. Tally began at KT Innovations in 2008 and is now a joint project of Building Transparency, KT Innovations, thinkstep and Autodesk. It does not suit product LCA outside buildings and needs a Revit licence, and it publishes no user count, so its adoption score is conservative. We compared documented features and published prices.

    Strengths

    • +Published USD prices: $695 Basic and $995 Premium floating licences per year
    • +Works inside the Revit model designers already use
    • +10-day free trial

    Limitations

    • −Buildings only, not consumer or industrial products
    • −Requires an Autodesk Revit licence
    • −No published user count

    SummaryTally is the best choice for architects who want LCA inside Revit because a $695 yearly licence covers whole-building and design-option comparisons. It does not cover product LCA.
