HiQLCD is a China-based Life Cycle Assessment (LCA) database that provides comprehensive, complete, and transparent carbon emissions data. It serves as a critical resource for advancing data-driven sustainability practices across industries.

In this interview, we speak with Johnson Gui to gain a deeper understanding of how HiQLCD is supporting China’s net-zero transition and how its collaboration with Carbon Minds is contributing to industry-wide sustainability efforts.

Johnson Gui
CEO of HiQLCD

Could you give us a brief introduction to your company?

HiQLCD (High-Quality Life Cycle Database) was founded by a team of LCA engineers with deep industry experience in China. Our mission is to develop the country’s most comprehensive and transparent life cycle inventory (LCI) database and continually raise the bar on data quality. Powered by AI, HiQLCD goes beyond a static dataset—our smart system can recommend the most relevant processes, regions, and technologies for your study. Covering 31 provinces, 27 key sectors, and nearly 900 product types, we deliver granular, China-specific carbon data that seamlessly integrates with global LCA tools, empowering any company—domestic or Western—to assess Scope 3 emissions in Chinese supply chains with confidence.

How is your company contributing to the net-zero transition in the chemical value chain?

Driving net-zero in chemicals requires truly up-to-date, locally relevant data—yet most international LCA databases lack robust China coverage. HiQLCD fills that gap by providing fully transparent, methodology-aligned datasets built on China’s actual industrial processes. We enable multinational corporations, certification bodies, and policymakers to replace generic proxies with precise, process-level data. This leads to more credible carbon footprints, stronger alignment with science-based targets, and faster progress toward net-zero—both in China and across global supply chains.

By combining Carbon Minds’ extensive chemical supply-chain maps with HiQLCD’s China-specific, transparent data, we create a truly comprehensive foundation for sustainability decisions worldwide.

What makes your solution unique?

HiQLCD is China’s first independently developed, process-level LCI database, engineered from the ground up for local relevance and global interoperability. Every dataset comes with full documentation—system boundaries, functional units, allocation choices—so you can see exactly how each emission factor was modeled. We rigorously follow ISO 14040/44 and sector-specific PCRs, support multiple allocation methods (cut-off, consequential, partitioning, etc.), and update our data frequently to reflect technology shifts and regional energy changes. That combination of transparency, methodological rigor, sectoral breadth, and real-time maintenance simply isn’t available elsewhere.

What added value does the collaboration with Carbon Minds create for your customers?

Carbon Minds brings the world’s most detailed chemical-supply-chain profiles; HiQLCD brings the highest-resolution China data. By linking these two worlds, customers get assessments that are not only globally comparable but deeply rooted in local reality. Companies can trust that their Scope 3 footprints fully reflect Chinese production practices, boosting the credibility of their sustainability reports, satisfying regulators, and guiding stronger decarbonization strategies across every link of the value chain.
