These are the 7 life cycle assessment software options to consider in 2026:
- Dcycle
- SimaPro
- openLCA
- Air.e LCA
- Sphera LCA for Experts, formerly GaBi
- One Click LCA
- Ecochain
Life cycle assessment software helps teams understand environmental impacts across a product system, from materials and production to the relevant use and end-of-life stages. The right tool should support the study the company actually needs, whether that means internal ecodesign, a customer product footprint or the preparation of an Environmental Product Declaration.
The difficult part is not only calculating an impact score. Teams need appropriate boundaries, usable background datasets, reliable supplier information and an explanation of the assumptions behind the model. Structured data collection makes those inputs easier to maintain as products, suppliers and manufacturing processes change.
The seven options below serve different users and sectors. Some prioritise expert modelling, others product portfolios, construction workflows or connected environmental data. This is an editorial shortlist, not a claim that one platform fits every study or automatically verifies its results. Define the intended output before comparing licences and features.
7 best life cycle assessment software options
1. Dcycle
Dcycle is an environmental data platform with product-level life cycle assessment capabilities. Its approach connects product modelling with operational information that may already exist in bills of materials, energy records, transport information and supplier submissions. Dedicated LCA projects provide a place to organise the related data, reports and deliverables.
The platform documents a visual canvas for materials, processes, transport and other life cycle stages, together with dynamic recalculation and scenario comparison. This is useful when a product team wants to investigate a design change without treating every alternative as a completely separate data collection project. Model boundaries and assumptions still need to reflect the study’s purpose.
Dcycle also connects LCA work with a broader environmental data environment. Relevant inputs may support corporate disclosures or other processes, including Spain-specific EINF reporting. Reuse does not mean a product study can be copied directly into every framework. Product and organisational boundaries, periods and calculation methods must remain clear.
For companies managing several environmental uses, the value is a maintained data foundation rather than a standalone annual calculation. Test a representative product with real source records, a material change and an allocation decision. Confirm the impact methods, dataset licences, calculation detail and output formats needed for the intended study, especially where an EPD programme or independent reviewer has specific requirements.
- Provides product-level LCA within a broader environmental data platform.
- Supports visual modelling of materials, processes and life cycle stages.
- Recalculates model results when relevant inputs change.
- Enables comparison of product and design scenarios.
- Documents assumptions and discussion around model elements.
- Supports product portfolios, multiple outputs and LCA report preparation.
- Helps teams reuse suitable operational inputs for reporting and business decisions.
2. SimaPro
SimaPro is an established technical LCA platform developed by PRé Sustainability. It is relevant to practitioners who need detailed process models, background datasets, impact assessment methods and a clear understanding of the assumptions that shape the study.
Its modelling environment supports work on complex product systems and comparison of alternative scenarios. The practical requirements depend on the edition, datasets and intended use. Buyers should confirm database packages and the methods available rather than assume every dataset or advanced analysis is included in one licence.
SimaPro can suit expert teams preparing rigorous studies or EPD-related analyses. When considering SimaPro alternatives, compare the complete workflow, including model maintenance, reviews and exchange with other systems. A specialised tool can be valuable without needing to replace the company’s corporate environmental data platform.
- Supports detailed, process-based LCA modelling.
- Offers access to background data and several assessment approaches.
- Can suit trained practitioners and complex product studies.
- Requires a clear plan for database licensing, expertise and result exchange.
3. openLCA
openLCA is free, open-source LCA software developed by GreenDelta. It provides a modelling and calculation environment for users who want transparency and control over their studies, with background datasets available through separate data sources and packages.
Free software does not mean every study input is free. openLCA Nexus includes both free and paid databases, and implementation may require training or specialist support. The total cost depends on the chosen data, internal expertise and maintenance approach, not only the software licence.
It can suit research teams, universities and businesses with technical LCA capability. Confirm the selected database and impact-method compatibility, the approach to collaboration and how models will remain understandable when staff change. Existing collaboration options should be evaluated rather than assuming that open-source software must be used entirely offline or by one person.
- Provides an open-source calculation and modelling environment.
- Supports access to a range of separately supplied databases.
- Offers options for customisation and collaborative work.
- Requires planning for data licences, model ownership and technical support.
4. Air.e LCA
Air.e LCA is professional life cycle assessment software from Solid Forest. The current product information describes modelling of products, services and organisations, with several impact methods and applications such as ecodesign, product carbon footprints and Environmental Product Declarations.
It should not be described only as a simplified carbon calculator. Its value can include visual modelling, assessment of different environmental impacts and comparison of alternatives. Database availability, including ecoinvent use, should be checked against the proposed subscription and licence terms.
Use a real product model to assess whether the interface and methodology controls fit the team. Confirm the deployment arrangement, collaboration options, allocation methods and report requirements rather than relying on an unverified cloud-only description. If corporate accounting is also needed, examine how the LCA and organisational footprint workflows exchange relevant information.
- Supports professional LCA modelling beyond climate impact alone.
- Addresses products, services and organisational study contexts.
- Provides methods relevant to footprints, ecodesign and EPD preparation.
- Requires confirmation of deployment, databases and the proposed reporting workflow.
5. Sphera LCA for Experts, formerly GaBi
GaBi software is now known as Sphera LCA for Experts. It remains a relevant option for detailed product modelling, with Sphera’s managed LCA data supporting work across industrial materials and processes. The current product name makes the comparison easier to use when requesting a demonstration or quote.
The wider Sphera portfolio also includes LCA Automation for different portfolio-scale requirements. Do not treat the desktop expert tool, managed content and automation offering as one universally included product. Identify the configuration that fits the company’s number of studies and data maintenance needs.
For manufacturers, evaluate industry coverage, parameterisation, background-data licences and the route from model to reviewed output. Also check any required ERP or PLM connections rather than assuming they are native to every edition. A technical platform can support both a focused study and wider product work, but the appropriate scope should be defined before purchasing.
- Provides detailed LCA modelling under the current Sphera product name.
- Connects with managed background data for industrial applications.
- Sits alongside distinct portfolio-scale automation offerings.
- Requires clarity on licences, integrations and the exact product configuration.
6. One Click LCA
One Click LCA provides LCA and EPD software with a strong focus on construction and manufacturing. It is relevant when assessments need to connect with building models, bills of quantities, product documentation or construction-sector requirements.
For construction materials, the applicable product category rules, modules and programme requirements matter as much as the software interface. A building-level assessment and a product EPD may use related information but are not interchangeable deliverables.
Test the product or building workflow relevant to the business. Confirm the geographic datasets, standards, EPD programmes and import formats covered by the chosen tool. One Click LCA and SimaPro are different product options even though the provider’s current corporate information places them within the same group. Compare their workflows rather than counting them as unrelated companies.
- Focuses on construction and manufacturing environmental assessments.
- Supports LCA and EPD-related workflows within its product offering.
- Can connect with sector-specific data and design information.
- Requires validation of the selected tool, geography and programme coverage.
7. Ecochain
Ecochain offers product and portfolio footprinting software for manufacturers. Its current product positioning brings together applications previously described as Mobius and Helix, so buyers should assess the available product-level and portfolio workflows rather than assume the historical names represent separate unrelated tools.
The approach is relevant when a company wants environmental information to support repeatable product decisions. The LCA benefits depend on whether the model can help identify significant contributors and assess realistic changes, not simply generate more footprint numbers.
Ask for a demonstration using an actual manufacturing process and several products. Confirm the treatment of shared inputs, allocation, background data and report outputs. Where an EPD or externally reviewed footprint is required, check the applicable method and reviewer expectations. Accessible modelling does not remove the need to document study choices and data limitations.
- Supports product and portfolio footprinting for manufacturing.
- Combines related applications within the current Ecochain offering.
- Can help teams assess environmental changes across products.
- Requires testing of allocation, dataset coverage and intended deliverables.
Tip: Before buying LCA software, define whether you need ISO 14040/44 study-grade modeling, ISO 14067 product carbon footprints, or CSRD-ready product datapoints. The right tool depends on output format, not feature count alone.
LCA software comparison at a glance
The most useful comparison starts with the work the team needs to perform. A research model, construction EPD and repeatable manufacturing footprint may require different interfaces, data and review processes. These differences are more informative than unsupported rankings of which product is universally easiest or most accurate.
Comparison table:
| Software | Main use case | Important point to validate |
|---|---|---|
| Dcycle | Product LCA connected with environmental and operational data | Methods, source connections, evidence and required outputs |
| SimaPro | Detailed technical modelling and scenario analysis | Edition, database packages and expert workflow |
| openLCA | Open-source modelling with configurable data | Dataset licences, method compatibility and model maintenance |
| Air.e LCA | Professional modelling for several footprint and LCA uses | Deployment, database access and study requirements |
| Sphera LCA for Experts | Industrial modelling with managed background data | Exact tool, data packages and automation needs |
| One Click LCA | Construction and manufacturing LCA or EPD preparation | Product type, geography, programme and import formats |
| Ecochain | Manufacturing product and portfolio footprinting | Allocation, portfolio coverage and output requirements |
Treat the table as a shortlist, not a substitute for a pilot. Software fees, database access, learning needs, corporate reporting connections and review costs should all be checked against the proposed offer. The same product can be a strong fit for one workflow and an unnecessarily complicated choice for another.

Request a demoWhy life cycle assessment software matters in 2026
Product teams increasingly need information that explains the environmental consequences of materials, manufacturing choices and supplier changes. LCA software can make those assessments easier to update and compare, especially when a company maintains several products rather than commissioning an isolated study.
The business need should still be defined carefully. Not every company is legally required to conduct a full LCA, and not every customer request needs the same level of analysis. Life cycle assessment provides a broader environmental perspective than a single climate indicator, but its suitability depends on the decision and intended communication.
From a voluntary study to a practical business requirement
An LCA can support ecodesign, purchasing and responses to buyers seeking environmental documentation. It can reveal that the largest impact occurs outside the factory, or that a material change reduces one impact while increasing another. Those findings help teams choose where further investigation is worthwhile.
Avoid describing every study as immediately customer-ready. The evidence needed for an internal comparison may differ from that required for a public claim or declaration. Define the audience and the level of review before deciding what the software must produce.
UK and EU requirements
UK and EU companies may encounter product-specific rules, customer specifications and procurement requirements that ask for environmental information. The relevant obligation depends on the product, market and contract. National climate strategies or general environmental legislation do not, by themselves, impose an identical LCA requirement on every business.
Where CSRD reporting applies, relevant product and value-chain information may contribute to disclosures. That does not mean every SKU must automatically receive a full LCA. Assess the reporting requirement separately from a product footprint, EPD or passport project.
LCA and corporate carbon accounting
A corporate carbon footprint concerns an organisational emissions inventory within a defined boundary and period. LCA studies concern a product system or service and can assess several environmental impact categories. Their data may overlap while their results serve different purposes.
A product footprint focuses on greenhouse gas emissions at product level. It is not necessarily a complete multi-impact LCA. When the same records support corporate and product work, retain the appropriate methods and allocation rules to avoid inconsistent calculations or double counting.
4 stages an LCA workflow should support
1. Define the goal and scope
Start with the decision or communication the study must support. Identify the product system, functional unit or appropriate declared unit, relevant boundaries and intended audience. A comparison of two products needs a consistent basis for the service or function being compared.
Software should make these choices visible instead of treating them as a note added after calculation. If one option is modelled per kilogram and another per unit of service, the numerical comparison may be misleading. The team should agree the basis before collecting large volumes of data.
2. Build the life cycle inventory
The inventory records inputs and outputs across the selected product system. Materials, energy, transport, emissions and waste may come from internal measurements, supplier information or background datasets. Preserve the source and the period so reviewers can understand how representative the information is.
Distinguish primary activity data from assumptions and secondary datasets. Missing information can sometimes be addressed with an appropriate estimate, but that choice must be documented. A model with every field filled is not necessarily more credible than one that explains its limitations clearly.
3. Assess environmental impacts
Impact assessment translates the inventory into environmental indicators using the selected method. Climate change, acidification, eutrophication, resource use and other categories describe different aspects of performance. Choose the method and categories that fit the study and any applicable programme rules.
Do not compare results generated with incompatible methods as if the values meant the same thing. Confirm units, characterisation factors and the treatment of relevant flows. A product may improve in one category and worsen in another, making a multi-impact view important for some decisions.
4. Interpret results and document limitations
Interpretation considers the findings in relation to the goal and scope. Examine significant contributors, data gaps and assumptions that may change the conclusion. Where appropriate, sensitivity analysis helps assess whether a design decision remains useful under plausible alternative inputs.
The final report should explain what can and cannot be concluded. An internal hotspot study should not be presented as a verified comparative claim without the required review. Software can organise the evidence, but the study owner remains responsible for the meaning and use of its results.
6 features to evaluate in LCA software
1. Methods that fit the required output
Evaluate the approach required by the study, including ISO 14040 and ISO 14044 principles, product carbon footprint requirements or relevant programme rules. PAS 2050 addresses life cycle greenhouse gas assessment of products, rather than serving as a universal multi-impact LCA method.
Also confirm whether ISO 14067 or GHG Protocol product guidance is relevant to the intended footprint. These are not interchangeable labels that prove a study is complete. Ask how the platform records boundaries, assumptions and methodological choices, and what additional review the output requires.
2. Suitable background data
The database should cover the materials, processes and regions that matter to the product. Check the dataset version, geography, time period and modelling approach. The nearest available dataset may be a reasonable proxy, but that judgement should remain visible.
Confirm licence terms and update arrangements before comparing total costs. Access to a database in one application does not necessarily permit unrestricted reuse or export elsewhere. Also establish how an update affects previous studies and whether earlier results remain reproducible.
3. Allocation and multiple products
Manufacturing processes can produce several outputs or share energy and materials across product lines. The allocation approach can materially affect the results. Agree the appropriate treatment under the chosen methodology rather than selecting whichever option produces the lowest number.
Dcycle documents co-product allocation using approaches such as economic, mass, energy or custom percentages. During evaluation, test a real shared process and the reasoning behind the selected allocation. The availability of a setting is not proof that every possible use is methodologically appropriate.
4. Connections to operational sources
Bills of materials, supplier records, energy consumption and transport activity often already exist in business systems. The platform should explain how those records reach the model, how they are validated and which parts still require human review.
Assess platform selection around a realistic source-to-result workflow. Ask what happens when a BOM changes, a supplier replaces a material or a utility record is corrected. Integration is useful only if the model remains understandable after those changes.
5. Reports and evidence for the intended audience
The output may be an internal analysis, customer footprint, EPD submission or study for independent review. Define that deliverable before buying. EPD verification involves programme and review requirements beyond exporting an LCA result to a document.
Dcycle documents LCA reports in PDF and Word, with templates structured around relevant ISO standards. Confirm that the report includes the necessary study content and that any EPD programme accepts the proposed process. A template does not automatically provide third-party verification.
6. Scalability and usable review views
Portfolio-scale work needs consistent product identifiers, model organisation and a way to find significant changes. Test several related products rather than only one model. A reusable component should help maintain consistency without hiding differences between products.
An impact dashboard can make stage contributions easier to inspect, as Dcycle’s documented LCA dashboard illustrates. Reviewers still need access to the inputs and assumptions behind the chart. Visual clarity and methodological transparency should be evaluated together.

See the platform5 mistakes when choosing life cycle assessment software
1. Buying modelling depth before defining outputs
A highly specialised tool can be a poor fit when the team only needs a repeatable internal product comparison. The opposite problem occurs when a simple calculator is selected for a study that requires detailed process modelling, several impact categories or a formal review.
Document the intended audience, required method and deliverable first. Then identify the capabilities needed to produce it. Modelling depth should follow the study requirement rather than serve as a proxy for quality on its own.
2. Treating LCA as a separate data island
Product studies can become difficult to update when supplier and operational information must be copied repeatedly. That creates reconciliation work and makes it harder to explain why a product result differs from another internal calculation.
Use a controlled supplier data workflow and test one product with actual BOM, energy and transport records. Keep the differences between product and organisational calculations clear. Connected inputs are useful, but the same total should not be transferred between inventories without the appropriate boundary and allocation treatment.
3. Ignoring the complete cost
Software fees are only part of the budget. Include background databases, implementation, training, model maintenance and any independent review. Open-source tools can be economical, but paid data and specialist time may still be necessary.
Compare a realistic multi-year workflow instead of assuming that one licence model is always cheaper. Ask how costs change when the team adds users, sites, products or datasets. Also determine whether maintaining an internal expert team or using external support better fits the organisation’s study volume.
4. Leaving methodology documentation until the end
A result without boundaries, data sources, allocation choices and limitations is hard to defend. Reconstructing those decisions after the calculation can introduce errors and leave the company dependent on the memory of the person who built the model.
Maintain records as the study develops. Access to supporting source files can improve review, but files should also be linked to the relevant input or assumption. Test whether another team member can understand the model without an informal explanation from its original author.
5. Confusing passport readiness with compliance
Machine-readable product information is useful, but a structured export is not automatically a compliant Digital Product Passport. Requirements depend on the applicable product rules, identifiers, information fields and arrangements for data access.
Ask how the platform makes model outputs available for future or applicable passport uses. Keep current obligations separate from planned capabilities. Avoid selecting a tool solely on a statement that a PDF is insufficient or that every product already needs a passport in 2026.
4 steps to implement LCA software
1. Choose a representative product and study goal
Select a product that reflects the materials and processes the business needs to assess. Define whether the first deliverable is an internal baseline, ecodesign comparison, customer response or preparation for an EPD. The pilot should be manageable without being so simple that it hides the important issues.
Review customer requests where they influence the output. Confirm the requested unit, boundary, period and evidence instead of assuming that any carbon figure will satisfy the buyer. A clear acceptance criterion makes the pilot more useful than a general demonstration.
2. Establish data ownership and quality rules
Identify who owns the BOM, energy information, transport records and supplier communication. Agree how missing or unusual values will be handled. A central platform will not resolve unclear responsibility if nobody is accountable for validating an input.
Preserve source attribution so the team can investigate corrections and follow up questions. Distinguish measured values, estimates and secondary data. The inventory owner should know which inputs are reliable enough for the first output and which need improvement.
3. Test calculation, review and export
Build the model with real records and examine at least one material change, one uncertain input and one shared-process allocation. Check whether the team can reproduce the result and explain how it changed. The pilot should test the entire workflow, not only the speed of generating a chart.
Share a sample report with the intended reviewer where appropriate. Confirm the information required for independent review or programme submission. Correct gaps before applying the configuration to many products, because a small modelling error can become a repeated portfolio-wide problem.
4. Scale with a maintained portfolio structure
Agree how product families, shared components and historical studies will be organised. Avoid creating a new unmanaged model for every variant if a controlled reusable structure fits the methodology. At the same time, do not conceal differences that matter to the assessment.
Dcycle’s documented LCA folders provide an example of organising studies by product, customer or year. Folder organisation is not formal version control, so test history and review requirements separately. Schedule updates when important operational or methodological changes occur.
Ready to connect product LCA with CSRD, carbon footprint, and supplier data on one platform?
Talk to our teamFuture trends in LCA and Digital Product Passports
Product information is becoming more connected across design, supply chains and market communication. Under the EU ecodesign framework, product-specific rules define detailed requirements for relevant groups. A general policy direction should not be presented as an identical current passport obligation for every product.
For software buyers, the practical issue is data portability and a maintained relationship between product identifiers and assessment information. Ask what can be exported, in which format and with which supporting context. Also confirm access arrangements and responsibilities where a separate system provides the passport service.
LCA remains an assessment process, while a passport is an information mechanism. Some assessment data may be relevant, but the two are not interchangeable. Preserve the source, method and boundaries behind shared results so a product record does not become a set of disconnected environmental claims.
Connecting LCA with environmental management
Product studies can inform material selection, waste prevention, energy decisions and supplier discussions. Those findings may also support an environmental management system. The value lies in identifying relevant operational actions, not simply attaching a footprint report to a certification folder.
The relationship between LCA and ISO 14001 should be understood carefully. A life cycle perspective in environmental management does not automatically mean every company needs a full ISO 14040/14044 study for every product. Define the level of analysis appropriate to the management decision and any separate external requirements.
Use the results to set priorities and assess progress with a consistent method. A lower modelled score caused by a database update is not necessarily an operational improvement. Teams should explain whether changes arise from actual activity, revised assumptions or methodological developments.
Why Dcycle connects life cycle assessment with operational data
Dcycle treats product LCA as part of a broader environmental data foundation. The product model remains important, but its inputs should also be maintainable as business activity changes. This approach is relevant to companies that want product studies to support reporting, savings and operational decisions rather than remain isolated deliverables.
The visual canvas brings materials, processes, transport and other stages into a model that can be reviewed and adjusted. A team can explore a supplier or design change while keeping the original study purpose in view. Scenario comparison is most useful when the alternatives share a compatible basis and the relevant trade-offs are visible.
Documented LCA assumptions add context directly to model blocks. Team members can discuss a hypothesis, contribute information and resolve comments. This makes choices about materials, transport distances or end-of-life scenarios easier to understand than maintaining the explanation in a separate email thread.
Where a process produces several outputs, the platform documents multiple final products and allocation options. These functions support a more realistic product system, but the user still needs to justify the method selected. An economic, mass or energy allocation should reflect the study requirements rather than be chosen only for a favourable result.
The platform’s documented report preparation can bring selected products and impact categories into an editable output. This helps teams communicate results without rebuilding the report entirely outside the data environment. Independent review, EPD programme requirements and any public comparative claim still need their own assessment.
Connecting relevant operational inputs can also reduce repeated collection. Materials, energy and logistics information may support product studies and corporate work, provided their boundaries and calculation rules remain distinct. The same data foundation should make those relationships clearer rather than encourage copying incompatible results.
Companies should confirm the exact background data, impact methods and integrations available for their use case. They should also test historical reproducibility, report detail and the process for updating a model after a significant change. Those practical checks establish whether the platform fits the intended work better than a generic claim of standards compatibility.
For teams seeking that connected approach, Dcycle is a relevant option alongside expert modelling and sector-specific tools. Its value is the combination of product modelling, documented assumptions and reusable environmental information. The objective is a process that stays useful as products evolve, while retaining the evidence needed to explain decisions.
Conclusion
The best life cycle assessment software depends on the study, the people maintaining it and the output required. Compare the seven options using real product data. Confirm methods, database access, allocation, evidence and exports before treating a feature list as proof of suitability.
Prioritise a clear goal and scope, appropriate data quality and a maintained explanation of the model. Separate internal analysis from EPD verification, public claims and product-passport obligations. Automation should reduce repeated work while preserving the judgement needed for a credible assessment.
Dcycle is a relevant candidate for companies that want LCA connected with environmental and operational data. A controlled pilot will show whether that integrated approach or a more specialised modelling tool fits the business. The aim is reliable product information that supports design choices, reporting, savings and ongoing improvement.
Frequently asked questions (FAQs)
What is the difference between carbon footprint and life cycle assessment?
Carbon footprint focuses on greenhouse gas emissions, often for a product or organization. Life cycle assessment evaluates broader environmental impacts across stages such as materials, manufacturing, transport, use, and end of life. Many companies need both, with consistent data between product and corporate reporting.
Is Dcycle an LCA tool or an environmental data platform?
Dcycle is an environmental data platform with native product-level LCA and corporate carbon footprint capabilities. It suits teams that need lifecycle assessment connected to operational data, cost decisions, CSRD, EINF, Taxonomy and SBTi, not LCA modelling alone in a silo.
Which LCA software is best for SMEs?
SMEs often need fast product footprints and clear outputs for customers or tenders, not full expert modeling on day one. Compare Air.e LCA, Dcycle, or OpenLCA based on team skills, database costs, and whether you also need corporate CSRD reporting from the same data.
What methodologies should LCA software support?
Look for alignment with ISO 14040/44 for LCA studies, ISO 14067 or PAS 2050 for product carbon footprints, and GHG Protocol product guidance where relevant. Methodology documentation and auditor-ready exports matter as much as calculation engines.
Can LCA data support CSRD reporting?
Yes, when product-level environmental datapoints connect to your CSRD materiality assessment and ESRS disclosures. Platforms that unify product LCA with corporate environmental data reduce duplication between product claims, operational decisions and reporting outputs.
What is the first step to implement LCA software?
Map one priority product, define the study goal (eco-design, customer request, EPD, or internal baseline), and list data sources for materials, energy, and transport. Run a pilot on that single product before scaling to the full portfolio.
When is dedicated LCA software more useful than a consultant or an Excel model?
Dedicated software becomes more useful when LCAs must be updated regularly, compared across products, reviewed by customers or verifiers, or connected to operational and reporting data. Consultants can still add value for complex studies and methodological decisions, while software provides a repeatable system that the internal team can maintain between projects.
