What happened
Electrolytic aluminum, an energy-intensive sector, faces dual carbon pressures: domestic renewable consumption mandates effective August 1 and the EU's CBAM, which adds nearly 340 euros per ton in carbon costs on exports, cutting export value by 8.3%.
The industry's traditional focus on electricity prices is shifting to carbon costs, as low-carbon aluminum commands a green premium of 300-800 yuan per ton, with a 10-ton carbon difference between coal-based and hydro-based aluminum.
Pioneers like Yunnan Wenshan Aluminum (over 80% green power), Baotou Aluminum (green power share up to 30%+, cutting 1.5 million tons of carbon annually), and Weiqiao (solar and molten salt storage) demonstrate green investments as a differentiator.
Why it matters
The shift from price-based to carbon-based competition redefines the aluminum industry's core logic, making green power adoption a survival imperative rather than an option.
Challenges remain: uneven green power distribution, pricing, and consumption guarantees require gradual, resource-based transitions, not abrupt changes.
Systemic solutions, including equipment upgrades, recycling, and carbon footprint accounting, are needed to fully realize green value and support China's industrial foundation.
Key facts
CBAM imposes nearly 340 euros per ton carbon cost on aluminum exports to EU, reducing export value by 8.3%.
Coal-based aluminum emits about 10 tons more carbon than hydro-based per ton.
Low-carbon aluminum earns a green premium of 300-800 yuan per ton.
Yunnan Wenshan uses over 80% green power; Baotou Aluminum cut 1.5 million tons of carbon annually; Weiqiao uses solar and molten salt storage.
What to watch next
Policy developments in green power trading and cross-province transmission to ease access for aluminum firms.
Industry efforts to standardize carbon footprint accounting and gain international recognition for green aluminum.
