Digitalization Makes LCA More Accurate and Traceable

Digital tools bring real-time data, traceability, and automated updates to LCA, improving environmental decisions across the value chain.

From Static Data to Dynamic LCA

Life cycle assessment, or LCA, has become one of the most widely used tools for evaluating environmental impacts across a product’s value chain. Now, digitalization is pushing the methodology toward more dynamic and data-rich applications.

Traditional LCAs often rely on large datasets from databases that remain static or update only at set intervals. Digital tools can change that model by connecting assessments with operational data generated across production, logistics, energy use, and waste management.

As a result, companies can move from largely manual studies toward more dynamic assessments that reflect changing conditions more quickly.

Digitalized LCAs can also incorporate more granular measurements from production systems. This allows companies to account for variables such as changes in electricity sourcing, transportation routes, production efficiency, and specific recycling pathways. The result is not necessarily a completely real-time LCA in every application. However, more frequent and automated data updates can improve the accuracy, relevance, and usability of environmental assessments.

Digital Product Passports Expand Traceability

Digitalization can also connect LCA results with emerging digital product passport systems. Companies could use these connections to support carbon-footprint reporting, recycled-content verification, chemical transparency, and other sustainability metrics. More traceable information can strengthen decision-making for manufacturers, suppliers, customers, and policymakers. This integration also makes environmental information easier to update as production conditions change. Instead of relying only on historical averages, companies can increasingly work with data that reflect more recent material, energy, and logistics inputs.

Covestro Advances Digital LCA

Chemical and raw-material supplier Covestro is among the companies expanding the use of digital tools in life cycle assessment. The company has developed a platform that uses digital data to assess the climate impact of approximately 50,000 finished products through cradle-to-gate product carbon footprints. According to Covestro, TÜV Rheinland certifies the methodologies, which follow relevant ISO standards.

“Digitalization enables us to gather and process larger data sets automatically, while reflecting timely changes at our production sites,” says Dr. Torsten Heinemann, Global Head of Group Innovation and Sustainability at Covestro.

Heinemann adds that digitalization reduces reliance on manual spreadsheets and calculations while making annual data updates more efficient.

The platform combines information from several sources. Raw-material impact data come from suppliers or external databases, while energy consumption, waste, and other operational inputs can come directly from enterprise resource planning systems such as SAP. Covestro also evaluates environmental indicators beyond greenhouse gas emissions. These include categories such as acidification potential and photochemical ozone creation potential.

Circularity Depends on Trusted Data

Covestro also aims to improve data exchange across the value chain. Information generated through its digital tools can connect with data-exchange platforms such as Catena-X and SiGreen. These systems can support more harmonized information sharing between upstream suppliers and downstream customers. The broader objective is to improve transparency across the value chain and support more circular decision-making. When companies calculate LCAs using traceable and frequently updated data, stakeholders can identify where the largest environmental impacts occur. They can then prioritize improvements, particularly in greenhouse gas emissions, energy use, and material sourcing. However, digitalization alone cannot solve every data-quality challenge. Companies still need consistent methodologies, comparable datasets, and clear rules for how they collect and share environmental information.

Industry Partnerships Remain Important

Initiatives such as Together for Sustainability, or TfS, aim to establish standardized approaches for environmental data within the chemical industry. These efforts can help companies generate more comparable information across suppliers and organizations.

As LCA becomes more closely connected with digital production systems, product passports, and supply-chain platforms, its role may continue to evolve. The next step is not simply calculating environmental impacts faster. It is building a transparent data infrastructure that helps companies understand impacts, compare alternatives, and act on the results.
