The Significance of Data in LCA
Data plays a pivotal role in LCA, serving as the foundation for calculating environmental impacts and identifying areas for improvement. While LCA software tools provide a structured framework for conducting assessments, the quality and availability of data are crucial for ensuring the reliability and accuracy of the results.
Primary vs. Secondary Data: Striking a Balance
LCA practitioners typically gather data from two primary sources: primary data and secondary data. Primary data refers to information collected directly from the source, such as production processes or supplier inventories. This data is often considered more accurate as it reflects the specific conditions of the system under evaluation.
However, collecting primary data can be time-consuming and costly, especially for processes that are geographically dispersed or not under direct control. This is where secondary data, sourced from LCA databases, comes in handy.
LCA Databases: A Gateway to Environmental Information
LCA databases offer a comprehensive collection of life cycle inventory (LCI) datasets on energy, material and emissions associated with a specific component, process or product. These datasets allow LCA practitioners in industry and research to fill the gaps in their own inventories. These databases provide a cost-effective and efficient way to supplement primary data gaps, ensuring the completeness of LCA studies.
If we want to be more accurate in using the expressions "LCI database" or "LCA database", LCI databases provide Life Cycle Inventory datasets, while LCA databases include in addition Life Cycle Impact Assessments (LCIA) methods. Life Cycle Impact Assessment is a method to evaluate and increase the understanding of the potential environmental impacts of a product system across its entire life cycle. In common language the term LCA databases is used more, without having this distinction in mind.
ecoinvent: A Global Leader in LCA Databases
The ecoinvent database is a widely recognized and respected resource for LCA data. With over 20,000 LCI datasets and a global coverage, ecoinvent offers a comprehensive and up-to-date source of information for conducting LCAs.
One of the greatest benefits of the ecoinvent LCI database compared to other databases (such as the GaBi databases) lays in its transparent and traceable nature. Unlike other databases, ecoinvent offers datasets as individual unit process data, enabling detailed analysis of product life cycles. ecoinvent provides comprehensive documentation on data sources and methodologies, enhancing trust and credibility. Annual reports detail changes to the database, ensuring transparency and reliability. Moreover, ecoinvent allows for different allocation types, catering to various LCA study goals and scopes.

Frequently Asked Questions
What are LCA databases?
LCA databases are curated collections of life cycle inventory (LCI) datasets covering energy, material, and emission flows for specific components, processes, or products. They allow LCA practitioners to fill data gaps in their own inventories, making it more cost-effective and efficient to conduct complete Life Cycle Assessments without collecting all data from scratch. Well-known examples include ecoinvent, Carbon Minds, and the USLCI database.
What is life cycle inventory data?
Life cycle inventory (LCI) data is quantitative information on all inputs and outputs — including raw materials, energy, water, emissions, and waste — associated with a product or process across its entire life cycle. LCI data is the foundation of every Life Cycle Assessment: it feeds directly into the impact assessment phase, where environmental impacts are calculated and evaluated.
Is the ecoinvent database free?
No, the ecoinvent database is not free for commercial users. It requires a paid annual license, available for individuals, enterprises, and software developers. Free-of-charge licenses are available only for universities and schools in low- and low-middle-income countries as classified by the UN. Academic institutions in other countries can apply for educational licenses at reduced rates. Students are generally recommended to access ecoinvent through their faculty or professorship lead.
