As of January 1, 2026, the EU Carbon Border Adjustment Mechanism (CBAM) has officially entered its charging phase. For Chinese manufacturers exporting to Europe, carbon emissions are no longer a background management issue. They now affect order costs, customer negotiations, and long-term competitiveness in international supply chains.
According to Solarbe's analysis, exporters in Guangdong are facing a particularly direct challenge. If companies cannot provide measured emissions data, they may be forced to use the EU's default emissions values, which can significantly inflate their carbon-related costs. The article notes that for some aluminum products the default value can be around 1.6 times the actual figure, while in some steel categories it can be as high as five to six times. This means that carbon data transparency is no longer optional for export-oriented manufacturers.
The sectors most directly affected include aluminum processing, steel products, electronics, and home appliances, industries with deep manufacturing links to Guangdong's export economy. If companies continue to treat carbon management as a secondary compliance issue, they may quickly lose price competitiveness in the EU market.
At the same time, CBAM is not only a cost burden. It is also accelerating industrial upgrading. Solarbe highlights several practical response paths, two of which are especially relevant for clean energy providers: first, building an emissions accounting system that replaces default values with measured data; second, reducing Scope 2 emissions through rooftop solar self-consumption, which offers a more credible green power pathway than relying on certificates that are not fully recognized by EU rules. The article also notes that these steps align closely with China's zero-carbon factory policy direction.
From IKOS's perspective, this trend sends a very clear message: future competition in international markets will increasingly depend on carbon transparency, energy structure, and integrated decarbonization capability, not only on product price and delivery speed. For Chinese companies in solar, storage, inverters, and broader clean energy solutions, this creates a new commercial opening. The market is moving toward higher-value demand for distributed solar, self-consumption systems, storage coordination, and zero-carbon industrial infrastructure.

CBAM is not a short-term disruption. It is reshaping the long-term competitiveness framework for exporters. For Chinese clean energy companies, this is both a compliance challenge and a market-entry opportunity. Capabilities built around measured carbon data, self-consumption solar, storage coordination, and zero-carbon factory solutions are likely to become increasingly valuable in the restructuring of global supply chains.
