Recently, with the support of Carbon Newture’s digital carbon management services, Shanghai JISCO Electrical Technology Co., Ltd. (“Shanghai JISCO”) completed its organizational greenhouse gas emissions accounting and management and obtained a Greenhouse Gas Verification Statement issued by SGS.
This achievement has further enhanced the transparency and credibility of the company’s carbon emissions data while providing traceable and reliable data support for downstream customers’ supply chain carbon management and green procurement initiatives.
Notably, the collaboration between Carbon Newture and Shanghai JISCO represents a practical example of Baoshan District’s efforts to establish a “citywide model area for green and low-carbon development” and a “core functional area for green and low-carbon supply chains,” while supporting the green transformation of local enterprises.
On the one hand, Carbon Newture leveraged its proprietary AI-native digital carbon management platform to provide Shanghai JISCO with comprehensive carbon accounting, management and optimization services, delivering targeted carbon management support within the district. On the other hand, as a leading local manufacturer, Shanghai JISCO’s enhanced carbon management capabilities not only respond to the low-carbon requirements of downstream customers—including Hitachi Energy, GE Vernova, TBEA and CHINT—but also mark an important milestone in the company’s integration into global green and low-carbon supply chains.
01 Supply Chain Carbon Management by Leading Enterprises Is Driving Upstream Demand for Carbon Data
For companies in the energy, electrical equipment and equipment manufacturing sectors, a substantial proportion of emissions does not arise from their own operations but is distributed throughout their supply chains.
ABB, for example, reported that Scope 3 emissions accounted for more than 99.9% of its total emissions in 2025. Emissions from purchased goods and services alone were 72 times the combined total of its Scope 1 and Scope 2 emissions.[1] Envision Energy reported a similar pattern: Scope 3 emissions represented approximately 99.8% of its total emissions in 2025, with supplier-related emissions accounting for more than 95%.[2]
Such high proportions of Scope 3 emissions mean that leading companies cannot achieve their overall emissions reduction targets solely through energy efficiency improvements and energy transition measures at their own facilities. Scope 3 is therefore becoming a major focus of corporate low-carbon transition, with carbon management requirements extending upstream through procurement relationships.

The Scope 1 and Scope 2 emissions generated by upstream suppliers during production become part of their downstream customers’ Scope 3 emissions. Whether upstream companies can provide consistent and credible carbon data therefore directly affects the quality of downstream carbon accounting and the progress of supply chain decarbonization.
Although leading companies vary in their level of low-carbon development and supply chain carbon management maturity, their main carbon data collection and management measures generally fall into three categories:
Requiring suppliers to provide organizational carbon emissions data;
Requiring suppliers to provide product carbon footprint data;
Setting mandatory requirements for the use of renewable electricity and working with suppliers to develop emissions reduction roadmaps.
The diverse requirements of downstream customers place greater demands on suppliers’ carbon management capabilities. Without a standardized carbon management system, suppliers often need to reorganize and recalculate their data repeatedly to meet the different requirements of individual customers, making the process time-consuming and resource-intensive.
Upstream companies in the energy value chain should therefore improve not only their product performance but also their carbon management systems. By clearly identifying emissions from their production processes, they can establish a credible data foundation for collaborative decarbonization across the supply chain.
02 How Does Shanghai JISCO Respond to Customer Requirements Through Its Products and Carbon Data?
Located in the Luojing Digital Intelligence Industrial Park in Baoshan District, Shanghai, Shanghai JISCO specializes in the research, development, production and sale of transformer cores, transformer core limbs and grain-oriented electrical steel strips. Its downstream customers include ABB, CHINT Group, TBEA, CRRC and Schneider Electric.

As a silicon steel materials company, Shanghai JISCO is committed to making a meaningful contribution to the transformation of China’s renewable energy industry. Its silicon steel processing and transformer core products connect upstream steel materials with downstream power equipment, making the company an important link in the power equipment supply chain.
In response to regional and global demand for greener, lower-carbon supply chains, Shanghai JISCO is strengthening its capabilities in both product performance and carbon data management, providing support for collaborative decarbonization across the value chain.

Superior product performance provides an important foundation for Shanghai JISCO to help downstream equipment manufacturers reduce emissions. Silicon steel is a key material used in transformer cores, and indicators such as core loss and magnetic properties directly affect energy losses during transformer operation.
As high-efficiency silicon steel technology continues to advance, specific core loss can be reduced from more than 1 W/kg for conventional products to 0.5–0.6 W/kg, thereby lowering energy consumption and associated carbon emissions during transformer operation. By improving material utilization efficiency and processing capabilities, Shanghai JISCO helps downstream power equipment manufacturers enhance energy efficiency and supports the green and low-carbon transition of the wider value chain.

Carbon data capability is another essential foundation for Shanghai JISCO’s integration into green supply chains. Recognizing the low-carbon development trend across the industry, the company has further advanced the development of its corporate carbon management system on the basis of its existing quality, environmental and occupational health and safety management systems.
As downstream customers increasingly incorporate organizational greenhouse gas inventories, product carbon footprints and supply chain carbon management into green procurement and supplier evaluation systems, Shanghai JISCO has continued to improve its carbon data management processes. It is also working to address differences among customer requirements concerning inventory boundaries, data methodologies and information disclosure, thereby strengthening its carbon management and supply chain collaboration capabilities and moving from simply aligning with the industry’s low-carbon requirements to becoming deeply integrated into them.
Conclusion
By completing its organizational greenhouse gas inventory with the support of Carbon Newture’s digital carbon management platform, Shanghai JISCO has taken an important step toward improving its carbon management system and strengthening its supply chain collaboration capabilities. The project also provides a practical example for manufacturing companies in Baoshan District exploring pathways toward green and low-carbon transformation.
As global value chains become increasingly low-carbon and transparent, carbon management capabilities are emerging as an important foundation for manufacturing companies seeking to remain competitive. As a key supplier in the power equipment and renewable energy value chains, Shanghai JISCO will continue to strengthen its green manufacturing and carbon management capabilities, respond proactively to the low-carbon requirements of upstream and downstream partners, and promote collaborative decarbonization across the value chain.
