Taiwan Carbon Fee and Transition Risk Analysis
Comparable, citable analysis of carbon fee exposure and corporate disclosure, built from public sources. The Carbon Pricing Record tracks the rules themselves; the analysis on this page extends them to individual sectors and companies.
Data updated: 13 November 2026
What we offer
The analysis is built from public sources and comes in three layers:
| Layer | Content | Access |
|---|---|---|
| Policy tracking | Commitments, timelines and rule adjustments under Taiwan's carbon fee, voluntary reduction plans and planned emissions trading system, each item sourced and graded by strength of evidence | Carbon Pricing Record, CC BY 4.0 |
| Sector comparison | Company by company: carbon fee obligations, reduction plan rate tier and targets, IFRS adoption phase, international commitments, carbon price assumptions in sustainability reports and renewable electricity status, with an estimate of exposure if preferential rates are lost | By sector; semiconductors completed |
| Company analysis | For a specific company or borrower: feasibility of reduction targets, dependence on renewable electricity and consistency of disclosure | On commission |
Available as research data, briefings, expert calls or in-house training.
Semiconductor comparison: key findings
The comparison covers 17 semiconductor companies that are subject to the carbon fee and fall within the first two phases of Taiwan's adoption of IFRS sustainability disclosure standards. Sources are their 2025 sustainability reports, the Ministry of Environment's list of approved voluntary reduction plans, and the relevant regulations.
Exposure is highly concentrated. If all 17 missed their reduction plan targets and paid the general rate instead, the additional carbon fee at today's NT$300 (about €8.52) per tonne would total about NT$3.7 billion (about €105 million) a year, 95% of it from the seven largest. If the general rate rises after 2030 to NT$1,200–1,800 (about €34–51) per tonne, as the Carbon Fee Rate Review Committee has preliminarily suggested, the annual fee for each of the seven largest would range from several hundred million to over NT$20 billion (about €570 million) on failure.
Renewable electricity is the bottleneck. Electricity emissions under a reduction plan are always calculated with the base-year grid emission factor, so grid decarbonisation does not count toward a company's target; the electricity share can be met only by saving electricity or using renewables. Most companies are expanding capacity and using more electricity, which leaves renewables as the main lever. Taiwan originally aimed for renewables to supply 20% of electricity generation by 2025. The target has been postponed several times as build-out fell behind; the actual share in 2025 was about 13%, and on 28 October 2026 the Minister of Economic Affairs told the Legislative Yuan that 20% is now expected in 2029.
Disclosure assumptions diverge. Assumed carbon fee levels for 2030 range from NT$140 to NT$3,000 (about €4–85) per tonne, and only a few cite the Rate Review Committee's suggestion. None of the 17 analyses the loss of preferential rates, and 12 have not set an internal carbon price or do not disclose its value.
Who it is for
- Investors: assessing how carbon fee and renewable electricity costs affect portfolio earnings, and as material for stewardship engagement.
- Lenders: assessing transition risk and the feasibility of reduction targets for carbon-intensive borrowers.
- Audit firms and consultants: peer benchmarks for IFRS S2 scenario analysis and assurance work.
- Boards and sustainability teams: checking whether the carbon price assumptions in annual report sustainability sections are reasonable and consistent.
