What is SimaPro Craft?
Developed by PRé Sustainability, a pioneering force in environmental impact modeling since 1990, SimaPro is an acronym for System for Integrated eX–Ploration of Product LCA. The Craft version is specifically tailored to provide a streamlined, highly intuitive user interface without sacrificing the raw computational power of the full SimaPro analytical platform.
It allows users to build complex product models from raw material extraction (the cradle) to end-of-life processing (the grave). By inputting data regarding energy consumption, material flows, transport logistics, and emission outputs, SimaPro Craft calculates the overall environmental burden across multiple impact categories. These categories include global warming potential (carbon footprint), acidification, eutrophication, water scarcity, and ozone layer depletion.
By initiating a SimaPro Craft download, organizations gain immediate access to enterprise-grade sustainability modeling that complies with international ISO standards, enabling them to make data-driven ecological decisions.
Understanding Life Cycle Assessment (LCA)
To truly utilize SimaPro Craft to its fullest potential, it is important to understand the scientific methodology it is built upon. Life Cycle Assessment (LCA) is standardized globally under ISO 14040 and ISO 14044. It is a systematic approach that breaks down a product’s environmental impact into four distinct, mandatory phases:
1. Goal and Scope Definition
Before modeling in the software, an LCA practitioner must define what they are studying and why. Are you comparing a paper coffee cup to a ceramic mug? Are you assessing the cradle-to-gate emissions of an electric vehicle battery? The scope defines the functional unit (e.g., “1000 liters of coffee delivered at 90°C”) and the system boundaries, dictating exactly which stages of the life cycle will be included in the study.
2. Inventory Analysis (LCI)
This is where SimaPro Craft truly excels. You input every single material, energy input, and emission output associated with the product. For example, to model a simple plastic bottle, you would input the amount of petroleum extracted, the electricity used in the manufacturing plant, the water consumed for cooling, and the exact CO2 and particulate matter emitted during transportation. SimaPro connects these inputs to massive background databases so you don’t have to calculate the emissions of raw electricity generation yourself.
3. Impact Assessment (LCIA)
The software takes the massive inventory list—which can consist of thousands of individual chemical emissions—and translates them into environmental impact scores using standardized scientific methodologies. Instead of looking at a confusing list of raw emissions, SimaPro calculates relatable metrics, such as “This product has a Global Warming Potential of 320 kg CO2-equivalent” or “This process contributes to 0.5 kg of Phosphorus-equivalent eutrophication.”
4. Interpretation
Finally, SimaPro Craft helps you visualize and interpret the results. You can use Sankey diagrams, bar charts, and contribution trees to identify which part of your product’s life cycle is causing the most environmental damage. If the software shows that transportation accounts for 80% of your carbon footprint, you know exactly where to focus your sustainability efforts.
Why Choose SimaPro Craft for Your Organization?
The market for sustainability software is growing, but SimaPro Craft maintains a dominant position for several strategic reasons:
- Unmatched Scientific Rigor: SimaPro does not hide its calculation methods. It provides full transparency, allowing peer reviewers and auditors to trace every number back to its original source.
- Future-Proof Compliance: With the introduction of the EU Corporate Sustainability Reporting Directive (CSRD) and the SEC climate disclosure rules, companies need robust data. SimaPro Craft generates the exact type of data required for these regulatory frameworks.
- Cost-Effective Scaling: While enterprise sustainability projects can cost millions, SimaPro Craft provides a high ROI by preventing costly design mistakes early in the R&D phase (Eco-design).
- Seamless Offline Capabilities: Unlike many modern cloud-based tools that suffer from latency issues when handling massive datasets, SimaPro Craft utilizes a powerful local desktop architecture, ensuring lightning-fast calculations regardless of internet speed.
Deep Dive: Key Features and Capabilities
SimaPro Craft is packed with advanced functionalities designed for both beginners and seasoned LCA practitioners.
Intuitive Process Tree Modeling
Building an LCA model is like building a family tree for a product. SimaPro Craft uses a highly visual, drag-and-drop interface. You can easily link sub-assemblies (e.g., a car door, an engine block, a set of tires) to a main product (the complete car). If you change the material of the door from steel to carbon fiber, the software automatically recalculates the environmental impact of the entire vehicle.
Advanced Uncertainty Analysis (Monte Carlo Simulations)
Real-world supply chain data is rarely perfect. If you aren’t sure if transporting a part takes exactly 50 liters of diesel—maybe it takes 45, or 55—SimaPro Craft allows you to input statistical uncertainty ranges (standard deviations) for your data. It uses Monte Carlo simulations to run the calculation thousands of times, generating a probability curve. This proves to stakeholders that your environmental claims are statistically robust, not just based on a single, lucky guess.
Parameterized Modeling
Instead of creating a brand new model from scratch every time you change a variable (like the weight of a product), you can set up parameters. For example, you can link the amount of plastic used to a single “Weight” parameter. When you change the weight from 100g to 150g, the entire LCA model—including raw material extraction, manufacturing energy, and transport emissions—updates instantly.
Publication-Ready Visualizations
When you finish an LCA, you usually need to present it to stakeholders, professors, or government bodies. SimaPro Craft includes a dedicated results panel where you can generate:
- Bar Charts: For comparing different product scenarios or design alternatives side-by-side.
- Sankey Diagrams: For visually tracing the flow of materials, energy, and emissions through your product system.
- Spider/Radar Diagrams: For normalizing multiple impact categories (like climate change, water use, and land use) into a single, easy-to-read graph to identify trade-offs.
Multi-Language Support
While the primary interface is English, SimaPro Craft natively supports multiple languages, including Dutch, French, German, Spanish, Italian, and Portuguese, making it ideal for international research teams and multinational corporations.
Who Uses SimaPro Craft? (Industry Use Cases)
Utilizing the SimaPro Craft download provides massive real-world value across a wide variety of industries:
- Sustainability Consultants: Firms hired to calculate Corporate Carbon Footprints (Scope 1, 2, and especially Scope 3 emissions) rely heavily on SimaPro to map out complex, multi-tiered global supply chains.
- Product Designers & Engineers: Automotive, electronics, and packaging engineers use SimaPro during the R&D phase to choose materials that lower the product’s overall ecological footprint (Eco-design) before tooling begins.
- Academic Researchers: Universities worldwide use SimaPro to publish peer-reviewed papers on renewable energy systems, waste management, bio-based materials, and circular economy models.
- Government & Policy Makers: Agencies use LCA data generated in SimaPro to draft environmental legislation, create eco-labeling criteria (like the EU Ecolabel), and establish carbon tax baselines.
- Food & Agriculture Sector: Used to calculate the environmental impact of agricultural practices, dairy farming, food processing, and packaging waste.
SimaPro Craft vs. Competitors
To understand why SimaPro Craft is the most sought-after LCA software, it is helpful to look at how it stacks up against its main competitors in the market:
SimaPro vs. openLCA
openLCA is a popular open-source alternative. While openLCA is free to download, it lacks the polished, professional user interface of SimaPro. openLCA is notorious for crashing or freezing when handling extremely large, complex product systems or massive databases. SimaPro Craft, on the other hand, is built on a robust, proprietary database architecture that handles millions of data points smoothly. Furthermore, integrating complex datasets like ecoinvent into openLCA can be a technical nightmare for beginners, whereas SimaPro Craft has it seamlessly integrated.
SimaPro vs. Sphera (formerly GaBi)
Sphera is SimaPro’s biggest commercial rival. While Sphera is excellent for highly specific, heavy-industry processes (like oil refining or chemical manufacturing), it has a massive learning curve. SimaPro Craft is designed to be much more accessible and flexible, allowing users to build models up to 50% faster without sacrificing scientific accuracy. Sphera also pushes heavily toward cloud-based subscriptions, whereas SimaPro Craft retains the speed and privacy of a desktop application.
SimaPro vs. Umberto
Umberto focuses heavily on material flow analysis (MFA) and has great visual network diagrams for manufacturing facilities. However, when it comes to sheer depth of Life Cycle Impact Assessment methodologies and global environmental database support, SimaPro is universally considered the more comprehensive, scientifically rigorous tool.
Included Databases and Impact Assessment Methods
The true value of a SimaPro Craft download lies in its data. Calculating an LCA from scratch is virtually impossible; you must rely on high-quality background data. SimaPro provides seamless integration with these industry-leading databases:
The ecoinvent Database
This is the “gold standard” of LCA data globally. It contains thousands of datasets for energy generation, material production (metals, plastics, bio-based materials), transportation, and waste treatment. For example, if you need to know the exact emissions associated with producing 1 kg of stainless steel in Germany versus China, ecoinvent has that exact, peer-reviewed data readily available.
ELCD (European Life Cycle Database)
Maintained by the European Commission, this database provides high-quality data on metals, plastics, and energy systems specifically tailored to European regulatory standards.
Agri-footprint & Foodprint
Essential for food and agricultural LCAs, these specialized databases provide detailed data on crop production, fertilizer runoff, livestock emissions (methane), and land use change.
Impact Assessment Methodologies Included:
The software does not just spit out raw inventory data; it translates that data using globally recognized scientific methods:
- IPCC 2021: The most up-to-date scientific method for calculating Global Warming Potential (Carbon Footprint) over 20, 100, and 500-year horizons.
- ReCiPe 2016: The most comprehensive methodology available, calculating 18 different midpoint impact categories (like ozone depletion, human toxicity, and land use) and 3 endpoint categories (damage to human health, ecosystems, and resource availability).
