Theta® Core

Core Features

Theta Core operates as a flexible LCA engine that provides company or industry-specific workflows. Its methodology centers on offering different levels of integration to accommodate the varied data environments of its users, from those with limited digital systems to those with strong, connected data infrastructure. In practice, some of its main features:

• Web-based LCA generation at scale — Provides a browser-based environment for managing life cycle assessments across large product portfolios using custom company or industry workflows.

• Customisable workflows & delivery models — Offered either as a configurable tool that internal teams run or as a curated solution implemented by WAP, with workflows tailored to each organisation’s processes.

• Flexible integration levels — Supports services-based, semi-integrated and fully integrated setups, from manual population using an LCA engine through to end-to-end automation tied directly into product, BOM, supplier and environmental data.

• Support for EPR, DPP and PACT PCF use cases — Designed to manage LCAs required by extended producer responsibility schemes, Digital Product Passports and PACT-compliant Product Carbon Footprints from a single workflow layer.

• EPD development with openEPD and epd.world — Connects seamlessly to the openEPD format and the epd.world platform so LCA results can move straight into digital verification, PDF generation and publication, including API distribution to tools such as EC3.

• Enterprise integrations & partners — Lists integration partners including SAP, Oracle, Windchill and Autodesk, reflecting a focus on plugging into core ERP and PLM systems rather than replacing them.

Closing Insights

Theta Core sits within WAP Sustainability’s broader software suite (WAP's omnichannel platform) as the layer that turns LCA expertise into repeatable, data-connected workflows. Rather than replacing an LCA engine, it wraps around existing data environments and tools so manufacturers can manage LCAs for extended producer responsibility programmes, Digital Product Passports and PACT-compliant product carbon footprints from one place. WAP positions Theta Core both as a configurable tool that in-house teams can own and as a curated solution that WAP can operate for clients, reflecting its consulting roots and focus on managed services.

A notable aspect is the three integration paths. A services-based setup links Theta Core to internal sources but still relies on manual population and document-based verification, suiting smaller portfolios or fragmented data. The semi-integrated approach builds a digital workflow from LCA engine through epd.world and the openEPD format to EPD publication, cutting verification time roughly in half and routing results by API into tools such as EC3. At the fully integrated end, Theta Core connects directly to ERP, PLM and environmental data, enabling on-demand, pre-verified EPDs at scale. For manufacturers facing growing volumes of EPR, DPP and customer requests—as well as parallel Buy Clean-driven demand handled by sister tools like Theta for Construction Products—Theta Core offers a path from pilot projects to industrialised LCA and EPD production globally today.
