LCA software for apparel & footwear
SimaPro enables teams working in the apparel and footwear sector to calculate environmental impacts using fact-based sustainability metrics. From raw material sourcing to end-of-life, you gain the insights needed to reduce product footprints, strengthen reporting, and make confident design decisions.
Sustainability challenges in the apparel & footwear sector
- Intensifying regulatory pressure: Emerging requirements under the Ecodesign for Sustainable Products Regulation (ESPR) which introduces a Digital Product Passport (DPP), the Directive on Empowering Consumers for the Green Transition and the French eco-score drive the need for transparent and fact-based environmental information.
- Scope 3 emissions across global supply chains: The majority of a company’s climate impact sits upstream, often beyond direct control, in raw material acquisition and preprocessing such as fiber production, and in manufacturing including fabric production, dyeing, bleaching, finishing and other processing steps.
- Material transparency and primary data gaps: Cotton, polyester, leather, synthetics, blends. Each carries different environmental trade-offs, and supplier-specific data can be difficult to obtain and validate across global, opaque and multi-tiered supply chains.
- Product footprint information requests: Customers, value chain partners, retailers, and regulators show a growing expectation for product-level carbon and environmental footprint information that is transparent, reliable and comparable.
- Complex product portfolios: Seasonal collections, frequent SKU turnover, and multiple manufacturing regions make environmental impact calculations at scale challenging.
- Greenwashing and greenhushing: Sustainability communications must be backed by transparent methodologies and documented assumptions.
How SimaPro supports apparel & footwear sustainability & compliance
Regulatory-aligned LCA modeling
Model cradle-to-grave product life cycles following LCA methods, standards and calculation rules specified by the applicable legislation. SimaPro supports structured, transparent and flexible modeling that helps you align with regulatory requirements and reporting.
Scope 3 and supply chain impact analysis
Map upstream processes from fiber production and packaging materials to dyeing, assembly, and transport. Identify hotspots across tiers and regions using trusted life cycle inventory (LCI) databases.
Product footprint calculations
Quantify product-level environmental impacts across materials, manufacturing, transport, use, and end-of-life. Apply consistent modeling across products and extend insights beyond carbon to other impact categories.
Scenario comparison for design decisions
Compare how alternative materials, recycled content levels, sourcing options, manufacturing locations, or end-of-life pathways influence your product’s environmental performance using parameter-based modeling. Test assumptions before scaling changes.
Transparent documentation and reporting
Generate outputs that clearly document the selected methods, data sources, and results, supporting internal reporting and external disclosures with transparent, fact-based information.
Scalable solution with flexible integration
Incorporate sustainability metrics into your organization’s workflows with seamless integration across various systems. Automate data input and use configurable models and APIs to scale from single product LCA to entire portfolio assessment.
Key use cases for apparel & footwear teams
SimaPro supports practical, day-to-day sustainability work across design, procurement, and reporting teams.
- Product footprinting
Calculate footprints for individual garments or footwear products, covering greenhouse gas (GHG) emissions and other environmental impacts beyond climate change, including particulate matter, water use, resource use (fossils, minerals and metals), acidification, eutrophication and others. - Portfolio-level impact screening
Identify high-impact product categories, materials and processes across collections. - Eco-design improvements
Reduce product impact by comparing material blends, recycled content options, or production practices in early design stages. - Supplier footprint modeling
Integrate primary supplier data to refine upstream impact assessments.
From data to decision
A structured workflow makes implementation practical and scalable:
- Import supply chain and product data
Integrate primary data and complement with trusted LCI databases. - Calculate environmental impacts
Apply recognized impact assessment methods. - Analyze hotspots and scenarios
Identify key impact drivers and compare improvement options.
From insight to action step by step.
