GCL SI Leads the Charge in Carbon Emissions Transparency with TianGong Initiative

On June 12, 2025, coinciding with the opening of the SNEC PV Power Expo 2025, GCL System Integration Technology Co., Ltd. (commonly known as GCL SI) proudly announced its participation in the TianGong Initiative. This marks a historic moment as GCL SI becomes the first photovoltaic solar enterprise to join this pioneering effort focused on carbon emissions transparency.

The TianGong Initiative, spearheaded by Tsinghua University, strives to establish a comprehensive and internationally recognized framework for localized carbon data through the Carbon Footprint Industry Alliance (CFIA), a nonprofit organization dedicated to research in carbon emissions tracking. This initiative aims to create a life cycle data analysis platform that will provide a robust database of carbon factors while enhancing international data interoperability related to carbon emissions.

During the launch ceremony on June 11, key figures such as Zheng Ren, COO of GCL SI, Qi Jianchuan, deputy secretary-general of the TianGong Initiative and a research assistant at Tsinghua's School of Environment, along with Li Shubo, the operations director of Data Communication at Ant Digital, signed a tripartite agreement symbolizing their commitment to promoting transparent and verifiable carbon data within the solar industry.

At the forefront of innovation with low carbon emissions, GCL SI has developed a cutting-edge granular silicon production method (FBR) that significantly reduces its carbon footprint. Notably, this method emits only 37 kilograms of CO₂ equivalent per kilogram produced, resulting in over 2 million tons less CO₂ emissions for every 100,000 tons produced. This impressive achievement solidifies GCL SI’s status as a leader in sustainable practices within the solar energy sector.

Zheng Ren expressed the company’s pride in being the first solar enterprise participating in the TianGong Initiative, stating, "By connecting our carbon data platform, SiRo, to TianGong's life cycle data analysis platform, we transition from a linear model to a dynamic network linking vital resources within the solar sector and beyond. Together, we will drive innovation, reduce carbon emissions, and shape a sustainable future. We invite all partners to join us on this critical journey."

Collaboration with Ant Digital has allowed GCL SI to quantify its corporate carbon footprint and ensure blockchain-based traceability throughout its supply chain. The carbon footprint data of GCL SI’s products is now accessible on the TianGong life cycle data platform, serving as a benchmark example for China’s low-carbon data ecosystem and contributing to the global competitiveness of green supply chains.

As environmental concerns continue to grow, the response from industries worldwide is becoming increasingly vital. The solar sector’s commitment to sustainable practices, exemplified by GCL SI, underscores the importance of collaboration and innovation in the effort to combat climate change. GCL SI's proactive steps in joining the TianGong Initiative offer an inspiring model for other companies to follow, emphasizing that transparency in emissions tracking is not just beneficial for individual companies but is also essential for the industry's collective advancement.

In conclusion, GCL SI’s initiation into the TianGong Initiative reflects a significant leap forward in the pursuit of carbon emissions transparency in the solar energy sector. This endeavor sets a precedent for future collaborations aimed at enhancing sustainability and accountability within global supply chains while reinforcing GCL SI's position as a champion of low-emission innovation.
