FAQ

HiQLCD v1.5.0 provides over 120,000 datasets across 8 major industry sectors and 27 sub-sectors, including energy, metals, chemicals, batteries, automotive manufacturing, and waste management. The database covers 31 provincial-level regions in mainland China, with detailed geographical and technological representation.

You can search for datasets by product or process name through HiQ Query. Basic dataset information is available for review. For specific materials, technologies, or data requirements, our team can assist with dataset identification and matching.

Yes. HiQLCD includes geographically differentiated datasets covering 31 provincial-level regions in mainland China. Depending on the industry and process, datasets may represent national, provincial, or technology-specific production conditions, allowing more representative modeling of Chinese supply chains.

HiQLCD integrates data from industrial enterprises, industry associations, official statistics, research publications, and other documented sources. Through collaboration with Chinese industry organizations and research institutions, we develop datasets reflecting actual production technologies and supply chain conditions in China.

HiQLCD follows ISO 14040/14044 principles and the ILCD framework. Datasets undergo structured data processing, quality assessment, and technical review. Documentation includes information on data sources, system boundaries, methodologies, and modeling assumptions to support transparency and traceability.

Yes. HiQLCD's database methodology underwent an independent critical review led by Prof. Guido Sonnemann of the University of Bordeaux, following ISO 14071. In 2026, the database also completed a review involving Chinese experts from academia and major industrial sectors, further strengthening its methodological and industry-specific credibility.

HiQLCD supports three system models: Cut-off, Consequential, and EN 15804. These models provide different approaches to allocation and system modeling, supporting a range of LCA applications. Users can select the model most appropriate to their study objectives and methodological requirements.

HiQLCD focuses specifically on Chinese supply chains, offering detailed geographical and technological representation of local production processes. It complements international databases such as ecoinvent by providing China-specific background data, helping users reduce reliance on geographically or technologically less representative proxies.

Differences may arise from data collection periods, geographical coverage, production technologies, system boundaries, allocation methods, and background supply chains. HiQLCD incorporates China-specific production conditions, which may differ from the assumptions used in other databases. Comparisons should therefore be made under consistent methodological conditions.

Yes. HiQLCD datasets can complement ecoinvent and other LCA databases within the same modeling project, provided that system models, units, flows, and methodological assumptions are appropriately aligned. This approach is particularly useful for supply chains combining Chinese and international production activities.

HiQLCD supports widely used LCA tools, including openLCA, SimaPro, Sphera LCA for Experts (formerly GaBi) and Brightway, through compatible data formats and delivery arrangements. Compatibility may vary by software version and data format. Our team can help confirm the appropriate format for your workflow.

Yes. HiQLCD provides background LCI data for product carbon footprint (PCF), life cycle assessment (LCA), and Environmental Product Declaration (EPD) studies. HiQLCD data has been used in internationally published EPDs. Final compliance depends on the applicable standards, PCRs, and verification requirements.

HiQLCD can provide China-specific background data for LCA studies supporting environmental reporting and regulatory assessment, including battery supply chain analysis. The suitability of specific datasets depends on the applicable regulation, methodological requirements, and study scope.

HiQLCD offers Basic and Industry Packages, as well as individual dataset purchases. Single-user and Enterprise licensing options are available to accommodate different research and organizational needs. Contact our team to identify the most suitable option.

Yes. Individual LCI datasets are available for purchase, making it possible to obtain specific materials or processes without purchasing a complete database package. Our team can help confirm dataset availability and provide a quotation based on your requirements.

The Basic Package provides general background LCI data across major industries. Industry Packages offer more detailed coverage of specific sectors, including additional products, production technologies, and regional variations. Industry Packages are available as add-ons to the Basic Package.

A Single-user License is intended for one authorized user, while an Enterprise License supports multiple authorized users within the same organization, subject to the applicable license agreement. Enterprise licensing is available for teams requiring shared database access.

HiQLCD licenses are generally valid for one year. Database package subscriptions include updates released during the license period. Renewal terms and update entitlements for individual dataset purchases are governed by the applicable license agreement.

Yes. You can explore dataset information through HiQ Query. For specific research or business needs, our team may arrange limited access to selected datasets for evaluation, subject to approval.

Purchased datasets are delivered electronically in formats appropriate to the agreed software environment. Our team provides guidance on data access, delivery, and basic import-related questions. Delivery schedules and any additional technical services are confirmed during the purchasing process.
