GCL SI states it will track carbon emissions from polysilicon production to module assembly and shipping. Each module will have a QR code exposing its particular carbon emissions, safeguarded by blockchain tech to avoid tampering. It states this will use openness in preparation for looming Carbon Border Adjustment Mechanism (CBAM) guidelines.

GCL SI has actually presented an unique carbon-tracing system including a blockchain and QR code system. The vertically incorporated maker stated it will utilize the “carbon chain” to transparently trace its carbon footprint throughout its whole supply chain.
Every module will get a QR code exposing the carbon emissions of each production action. GCL SI stated it intends to accomplish complete openness of its carbon contents from the procurement, production, and transport of its items. It stated that the mix of blockchain and QR codes will supply total openness and high security, so information can not be damaged.
The goal is to trace carbon emissions in each production action. That consists of the production of metallurgical polysilicon, over to fluidized bed reactor (FBR) polysilicon improvement, the ingot-to-wafer-to-cell production actions, and ultimately, PV module assembly. GCL SI stated that it will ask third-party auditors to accredit the carbon emissions of each of these 6 actions separately. The reports from each production action will be integrated into a file available through a QR code on the modules.
The business began tracking its carbon footprint in 2019 to abide by French market guidelines. PV items developed for systems bigger than 100 kW in France should get a French Energy Regulation Commission (CRE) carbon footprint accreditation. GCL SI got accreditation company Certisolis to examine its module production procedures.
In addition, the business has actually picked accreditation bodies Ademe and CQC to accredit the carbon footprint of GCL SI processes associated to basic materials. With the system in location, the business adheres to the PAS205:2011 requirement, which controls ecological evaluations of items.
Now it is time to step up the effort once again, stated GCL SI Executive President Thomas Zhang.

“The carbon chain idea leverages advanced blockchain innovation and tactical collaborations to produce a smooth and transparent carbon platform,” stated Zhang. “It is a testimony to our unwavering dedication to sustainability and business duty. By accepting this pioneering practice, we decrease our carbon footprint and empower others to do the exact same.”
In between 2021 and 2023, GCL SI accepted reduce the carbon strength of its items by 70%, Zhang stated. This has actually been attained by executing different optimization strategies, such as heat insulation, a/c, and on-site PV generation, to power the production procedures.
