Sustainability reporting and ESG disclosure in Taiwan: what a Swedish company needs to know
Taiwan requires sustainability reporting from listed companies, but most suppliers do not. European obligations often reach further than Taiwanese law.
Why sustainability reporting reaches into Taiwan for a Swedish company
A Swedish company with a Taiwanese subsidiary or a major Taiwanese supplier faces two separate reporting obligations that operate in parallel. If the parent reports under European corporate sustainability reporting or due diligence directives, it is required to assess environmental and social performance across its entire value chain, including entities in Taiwan that may operate under no such local requirement.
The subsidiary in Taiwan may also have its own local reporting obligation if it is a listed company or a large entity by Taiwanese standards. These two obligations are independent: the parent's European requirement applies regardless of whether the Taiwan entity is required locally, and the Taiwan entity's local requirement applies regardless of the parent's European status.
The misalignment matters because it means a Taiwanese subsidiary or supplier may experience two separate sets of data requests, with different boundaries, different assurance expectations and different timings. Being clear about which obligation is behind each request simplifies compliance on both sides.
Taiwan's requirements for listed companies and large entities
Taiwan's Financial Supervisory Commission and the exchanges that list companies require sustainability reporting from certain entities. The requirement is phased by company size, sector and listing status, and has been introduced incrementally over successive years.
The regulator's requirements cover greenhouse gas inventory, water use, waste management and governance disclosures. The specific entities in scope, the timeline for implementation and the assurance expectations are set administratively by the Financial Supervisory Commission and communicated through the exchanges, and they change periodically.
A Taiwanese subsidiary that is listed or crosses certain size thresholds will have its own local reporting obligation. This obligation exists independently of whether the parent company is Swedish, European or subject to any foreign reporting requirement. Check with the Financial Supervisory Commission or your Taiwan tax and regulatory adviser whether a given entity is in scope, because the thresholds and sector definitions are precise and it is easy to misread them from a distance.
Greenhouse gas inventory: the three scopes and what they mean
Greenhouse gas accounting divides a company's emissions into three categories. Scope 1 covers direct emissions from sources the company owns or controls. Scope 2 covers emissions from energy purchased from others. Scope 3 covers all other upstream and downstream emissions: the energy and materials in the supply chain before the company receives them, and the emissions generated when customers or users consume the company's products.
For a Taiwanese manufacturer or supplier, Scope 1 and Scope 2 are the emissions the company itself can measure and potentially reduce. Scope 3 is usually far larger but also far harder to measure because it depends on suppliers, customers and end-users outside the company's direct control. Most of the value chain is in Scope 3.
When a Swedish parent company is required to report on its value chain, it typically needs Scope 3 data from its suppliers. A Taiwanese supplier with no local obligation to measure Scope 3 may find itself receiving a detailed questionnaire about emissions it has never quantified. This is the point at which a local reporting obligation and a foreign buyer's requirement collide.
Internationally aligned standards and the convergence toward common frameworks
International sustainability disclosure standards are converging toward common frameworks. The goal is to align what companies report on across different jurisdictions and different buyers so that a single set of underlying data can serve multiple reporting requirements. The reality is that convergence is incomplete and the boundaries, assurance expectations and specific obligations still differ.
A company reporting under European directives and a company reporting under Taiwan's Financial Supervisory Commission requirements may be measuring many of the same underlying emissions and social impacts. However, the boundaries of what counts, who is required to report, what assurance is expected and by when are not identical. The data may be compatible but the structure and the obligations are not.
For a group with entities in both Sweden and Taiwan, this means that underlying data can be harmonised to serve both requirements, but it requires deliberate design rather than assuming that meeting one requirement automatically meets the other. The boundaries are different and assurance expectations differ, so aligning the reporting architecture early saves significant rework later.
European obligations reaching into Taiwan: the buyer's dilemma
When a Swedish company is required to assess its value chain under European corporate sustainability reporting or due diligence directives, it must gather data from suppliers regardless of whether those suppliers face any local obligation to provide it. A Taiwanese manufacturer, service provider or component supplier may operate entirely within Taiwanese law and still find itself receiving questionnaires, audit requests and data demands from European customers.
The questionnaires typically ask for environmental management data, energy and emissions, social policies, grievance mechanisms and supply chain transparency. A Taiwanese supplier with no local requirement to measure or disclose these items may lack the systems, data and practices to answer. The burden falls on the supplier not because Taiwanese law requires it but because the European buyer is required to know it.
This is not a regulatory obligation in Taiwan but a contractual obligation to the buyer. It can be managed, but it requires the buyer to recognise that Taiwanese suppliers often start from zero on these disclosures and that the quality of data depends on the buyer's willingness to help the supplier build the capability, not simply to demand it.
The carbon border adjustment mechanism and what it means for Taiwanese goods
The European Union operates a carbon border adjustment mechanism as an import-side instrument. The mechanism prices emissions embedded in certain goods crossing the EU border and creates reporting obligations on the importer. The goods in scope, the coverage, the phase-in timeline and the calculation method are set by EU regulation and confirmed directly with European customs authorities rather than assumed from general frameworks.
For a Taiwanese exporter or a Swedish importer of Taiwanese goods, the carbon border adjustment mechanism means that the importer faces a cost obligation tied to the carbon intensity of the imported goods. To manage that cost, the importer needs data on the emissions involved in producing those goods, which means the importer will ask the Taiwanese supplier for detailed emissions data.
A Taiwanese supplier may not have locally applicable carbon pricing or carbon reporting requirements and may not have thought about the emissions involved in its own processes. The European importer, facing a cost obligation, will be motivated to request that data. This is a mechanism where a European policy tool reaches back into a Taiwanese supply chain not because Taiwan requires it but because Europe prices it.
Taiwan's carbon fee mechanism and how it affects liability
Taiwan operates a carbon fee mechanism that applies to emissions from large emitters. The fee is an economic instrument designed to create an incentive to reduce emissions. Entities subject to the fee can potentially reduce their liability through emissions reduction plans or through the use of offsets, and the precise rules and the current scope of the mechanism are set by Taiwan's environment ministry.
The carbon fee mechanism, its current coverage, the fee rate, the threshold at which entities are required to participate, the rules for offsets and the criteria for approved reduction plans all change over time and are set administratively by the environment ministry. They are not constants and they should be confirmed directly rather than inferred from published materials that may be out of date.
For a Swedish company with a Taiwanese subsidiary or a significant Taiwanese supplier, the carbon fee is a cost factor and a compliance obligation if the entity is in scope, but the scope and the mechanics are not self-evident from the law and require direct confirmation with the environment ministry or a Taiwan energy and environmental adviser.
Practical steps for a Swedish buyer engaging a Taiwanese supplier
If a Swedish company is required by European directives to assess its value chain, a practical approach to engaging a Taiwanese supplier starts with clarity about what data is needed and why. A supplier with no local obligation to collect the data needs to understand that the request comes from the buyer's own European reporting requirement, not from Taiwanese regulation.
Data quality is the binding constraint. A Taiwanese supplier asked to measure Scope 3 emissions for the first time, or to provide granular supply chain transparency, or to document social management practices may lack the systems and baseline understanding to produce reliable answers quickly. A buyer that recognises this constraint can support the supplier in building capability rather than simply demanding data that cannot yet be produced reliably.
The most productive engagements start with a questionnaire that is proportionate to the supplier's size and capability, a clear explanation of what will be done with the data, and a willingness to work with the supplier over time to improve data quality. A supplier that understands the buyer's obligation and sees the benefit of the relationship is more likely to invest in building the systems and capability to answer comprehensively.
Common questions
Does a Taiwanese subsidiary have to report under European directives if the parent is Swedish?
No. The subsidiary's reporting obligation depends on whether it is required by Taiwan's Financial Supervisory Commission or the exchanges, not on the parent's nationality or European reporting requirements. The parent, however, is required to assess the subsidiary and include it in the parent's own value chain assessment if the parent is subject to European reporting or due diligence directives.
What are the current carbon fee rates and thresholds in Taiwan?
The carbon fee mechanism's current rates, thresholds and scope are set by Taiwan's environment ministry and subject to change. Do not rely on figures or thresholds from published materials without confirming them directly with the environment ministry or a Taiwan environmental compliance adviser, as the mechanism is actively managed and details change periodically.
Can a Taiwanese supplier avoid answering sustainability questions if there is no local requirement?
A supplier can decline to answer, but doing so limits its access to European customers who are required to assess their value chain. If a supplier wants to maintain business with European buyers, answering the buyer's due diligence questions is effectively mandatory even if no local Taiwanese law requires it.
How do internationally aligned standards affect what a Taiwanese subsidiary needs to report?
If the subsidiary is required by Taiwan to report, it reports to the Taiwanese regulator regardless of any international convergence. The convergence affects how the parent can harmonise the subsidiary's data with the parent's own European reporting, but it does not change the subsidiary's local obligation or create new ones.
Does the carbon border adjustment mechanism apply to all Taiwanese goods exported to Europe?
The carbon border adjustment mechanism applies to specific goods in scope as defined by the European Union. Check with a European customs broker or the European Commission directly to confirm whether a particular product category is covered and what data the EU importer will need to gather.
