Can a Japanese steel or aluminium exporter deduct GX emissions trading costs from CBAM?
Only for a price effectively paid. Japan's GX emissions trading becomes mandatory for large emitters from 2026, with allowances largely free at first. Until a plant pays for allowances beyond its allocation, there is little to deduct. Keep the evidence ready.
What changes from 2026
Japan has moved its GX emissions trading from voluntary participation to a mandatory scheme for companies above an emissions threshold. Allocation is expected to be largely free in the early years.
What counts for CBAM
- Allowances actually bought and surrendered beyond the free amount.
- Any separate carbon levy actually paid.
- Net of rebates or compensation.
Check before declaring
The Commission decides how foreign carbon prices are recognised. Confirm the current rules and keep the allocation and surrender records for the year.
What Senseible does here
Senseible reads fuel, electricity and production documents into dated, fingerprinted installation records, the starting point for the actual emissions an EU importer asks for.
