Why Product Carbon Footprint (PCF) will be a business necessity after 2026 in Singapore

What is a Product Carbon Footprint (PCF)?

A Product Carbon Footprint measures the greenhouse gas emissions linked to a particular product. The result is normally expressed in kilograms or tonnes of carbon dioxide equivalent, written as kg CO₂e or tCO₂e.

This allows different greenhouse gases to be reported using a single common measurement. A PCF is not the same as a general company carbon footprint. It looks at one defined product or product group. The calculation may be prepared for:

• One manufactured item
• One kilogram of material
• One tonne of product
• One square metre of board or flooring
• One litre of liquid
• One packaged unit sold to a customer

The selected measurement is known as the functional unit or declared unit. It needs to be clear from the beginning. Otherwise, comparing the result with another product becomes difficult.

ISO 14067:2018 provides principles and requirements for calculating and reporting a product’s carbon footprint. It follows recognised life-cycle assessment principles while focusing specifically on climate impact.

Which emissions can be included in a PCF?

The calculation boundary depends on why the assessment is being done. A manufacturer may only need a cradle-to-gate assessment. This covers the product from raw material extraction until it leaves the factory. Another company may need a cradle-to-grave study, which continues through product use, recycling and final disposal.

Depending on the selected boundary, the PCF may include emissions from:

• Extraction and processing of raw materials
• Supplier manufacturing activities
• Electricity used at the production site
• Fuel used in boilers, furnaces or generators
• Refrigerants and industrial gases
• Product assembly and finishing
• Packaging materials
• Storage and warehousing
• Road, sea, rail or air transport
• Product use and maintenance
• Recycling, recovery or disposal

Not every source will carry the same weight. For one product, raw material production may dominate the footprint. For another, electricity or air freight may be the main issue. The calculation helps the business see that difference.

Why PCF will become more important after 2026

The shift is unlikely to happen through one rule or one deadline. It will come from several directions at once. A company may first receive a request from a multinational customer. Another may find a carbon-data section inside a tender. An exporter may be asked for embedded-emissions information.

A listed parent company may start collecting better Scope 3 data from its suppliers. This is how product carbon reporting moves through a supply chain. Slowly at first. Then it becomes part of normal commercial work.

1. Large buyers need better supplier data

Large companies cannot understand their value-chain emissions by looking only at office electricity and company vehicles. They also need information from manufacturers, logistics providers, packaging suppliers and other vendors.

As their reporting becomes more detailed, supplier questionnaires are becoming more detailed too. A buyer may ask for:

• Product-level greenhouse gas emissions
• Energy used during production
• Raw material quantities
• Recycled material content
• Packaging weight and type
• Transport distances and methods
• Emission-reduction actions
• Calculation standards and assumptions

For businesses working with several manufacturers, material suppliers and logistics partners, supply-chain ESG advisory can help organise supplier requests, review data gaps and improve value-chain transparency.

A completed PCF will not make every questionnaire easy. It does, however, give the supplier a working set of figures and supporting documents. Without it, staff may need to rebuild the same answer each time a customer asks.

2. Singapore’s reporting roadmap affects supply chains

Singapore’s climate-reporting requirements are being introduced in stages rather than applied to every company at once. All Singapore-listed companies are required to report Scope 1 and Scope 2 greenhouse gas emissions for financial years beginning on or after 1 January 2025.

Straits Times Index constituent companies must also report Scope 3 emissions from financial years beginning on or after 1 January 2026. Scope 3 reporting remains voluntary for other non-STI-listed companies until further notice. This does not create an automatic PCF requirement for every supplier.

The indirect effect still matters. When a listed customer needs a clearer picture of its value chain, it may ask suppliers for material, manufacturing, transport and product-emissions data.

Companies that have not yet measured their organisational emissions may begin with GHG, carbon and net-zero advisory before moving into detailed product-level calculations. This helps separate company-wide emissions from emissions allocated to a particular product.

3. Singapore’s carbon price has increased

Singapore’s carbon tax rose to S$45 per tonne of CO₂e on 1 January 2026. That rate applies for 2026 and 2027, with the government indicating a view toward S$50 to S$80 per tonne by 2030. The tax does not mean that every small business receives a direct carbon-tax bill. Its wider effect can still pass through electricity prices, materials, industrial services and supplier contracts.

Businesses that understand where a product uses the most energy or carbon-intensive material are in a better position to respond. They can test alternatives instead of making a broad promise to “go green” without knowing what needs to change.

4. Export customers are asking for greater transparency

Singapore companies supply customers across Europe, Asia, Australia, the Middle East and North America. Requirements differ between markets, but the overall request is similar: provide better environmental data. The EU Carbon Border Adjustment Mechanism entered its definitive regime on 1 January 2026.

Its initial product scope covers selected goods in cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. It does not automatically cover every electronic, medical, food or consumer product.

A normal PCF is not the same as a CBAM calculation. Exporters dealing with covered goods may need separate CBAM reporting advisory because CBAM follows its own product codes, calculation boundaries, embedded-emissions methods and evidence requirements.

Still, companies that already maintain clean production, energy and material records will usually be better prepared for carbon-related export requests. The same records often support both PCF work and more specialised reporting.

5. Environmental claims need evidence

Words such as “low carbon,” “sustainable” and “eco-friendly” appear on many product pages and packaging labels. Customers are becoming less willing to accept them without proof. A PCF gives a company a measured starting point. It can show whether a packaging change, new material or cleaner energy source has reduced emissions.

It can also stop the marketing team from making a claim that the available data cannot support. The calculation alone does not prove that a product is environmentally superior in every way. PCF measures climate impact.

6. Tender questions are becoming more detailed

A tender may not ask for a fully verified PCF. It may request simpler information, such as:

• Carbon emissions per unit of product
• Use of recycled materials
• Evidence of emission-reduction work
• Supplier environmental data
• Product life-cycle information
• A carbon-management plan

A company with organised records can answer these questions with less disruption. A company starting from zero may need to contact several departments, check old utility bills, chase suppliers and resolve inconsistent production figures. That takes time. It can also delay the submission.

7. Carbon reduction starts with finding the hotspot

Most businesses already know that cutting waste and energy use can save money. The problem is deciding where to begin. A PCF breaks the product into stages and shows which areas contribute most to the result. The hotspot may be:

• Aluminium or steel used in the product
• Imported ingredients
• Factory electricity
• Refrigerant leakage
• High levels of process waste
• Oversized packaging
• Long-distance road transport
• Air freight used for urgent shipments
• Energy consumed while the product is being used

Where factory electricity, boilers, cooling systems or production equipment make up a large part of the footprint, an energy-efficiency assessment can help identify where energy is being lost and which improvements are worth considering.

Which Singapore industries may need PCF first?

Almost any business selling a physical product can use PCF data. Some sectors are likely to receive requests earlier because they work with international buyers, large corporate customers or carbon-intensive materials. These may include:

Electronics products can involve complex regional supply chains, specialist materials and energy-intensive manufacturing. Buyers may request product data from component and contract-manufacturing partners.

Chemical products often require careful treatment of raw materials, process energy, yields, co-products and waste. Allocation can be a major part of the calculation.

Steel, aluminium, cement-based products, insulation, glass, boards and finishing materials are increasingly assessed during lower-carbon building projects.

The largest source may sit outside the factory. Agricultural ingredients, refrigeration, packaging and transport can all influence the final figure.

These businesses may need to consider controlled production environments, specialist materials, packaging and temperature-sensitive logistics.

Paper, plastic, glass, metal and composite packaging have different emissions profiles. Customers often want to compare material choices or lightweighting options.

Wood, metal, foam, textiles, plastics, coatings and international freight can all affect the footprint. Product durability and end-of-life assumptions may also matter.

Logistics companies can support customer PCF studies by providing fuel, distance, load, warehousing and refrigeration data. Better records make those calculations more defensible.

These sectors often work through strict customer specifications and multi-level supplier networks. Requests for product and material data can move down the chain quickly.

What are the business benefits of a PCF assessment?

A PCF should not be treated as a figure prepared only for a sustainability report. Used properly, it can support day-to-day decisions. The business may gain:

1. A clearer response to customer carbon questionnaires
2. Better preparation for product-related tenders
3. More organised supplier and production records
4. A measurable baseline for emission reduction
5. Better comparison between materials or packaging options
6. Early identification of energy and material waste
7. More supportable environmental claims
8. Stronger preparation for third-party verification
9. Better coordination between production, procurement and ESG teams

The figure is only one part of the value. The data collection process often reveals problems that were already costing the company money. A factory may discover that scrap records do not match purchasing data. A packaging team may find that cartons are larger than needed.

A procurement manager may learn that two suppliers offer similar materials but very different carbon information. Those findings can be useful even before the PCF is shared outside the company. Once the main emission sources are clear, the business can use the results to build a practical decarbonization plan with priorities, responsibilities and measurable reduction steps.

What can happen when a business has no PCF data?

Not having a PCF will not lead to an immediate penalty for most Singapore companies. The difficulty usually appears at an inconvenient time. A customer asks for a product footprint before renewing a contract. A tender requests carbon information three days before closing.

An overseas buyer wants material-level emissions. The available production records cover a different period, and nobody has contacted the main supplier yet. Common problems include:

• Delayed tender responses
• Repeated customer questionnaires
• Missing supplier information
• Unsupported green claims
• Inconsistent electricity or production records
• Difficulty comparing product improvements
• Higher cost for urgent consulting work
• Weak preparation for verification
• Reduced access to carbon-sensitive supply chains

How to prepare for PCF requests before 2027

A company does not need to assess every product at once. Starting with one product often makes more sense. Choose a commercially important item, frequently requested by customers or responsible for a large share of production. A practical preparation process may include the following steps.

• Select the priority product: Choose a product with a clear reason for assessment. It may be a major export item, a tender product or one frequently included in customer questionnaires.
• Define the product unit: State what the result will represent. For example, one unit, one kilogram, one tonne or one square metre of product.
• Set the assessment boundary: Decide whether the study will be cradle-to-gate, cradle-to-customer, cradle-to-grave or another clearly defined boundary.
• Map the real production process: Follow what actually happens at the site. Do not rely only on an old process diagram if production practices have changed.
• List the required data: The list may include bills of materials, production quantities, electricity, fuel, waste, packaging, transport and supplier information.
• Use a consistent reporting period: Energy, output and waste data should normally cover the same period. Mixing unrelated months or years can distort the allocation.
• Review emission factors: Emission factors should match the activity, geography, fuel, electricity source, material and reporting purpose as closely as practical.
• Allocate shared emissions carefully: Many sites produce several items using the same electricity, boiler, warehouse or production line. The allocation method needs a clear reason behind it.
• Record assumptions and exclusions: Not every figure will be perfect. Missing data, estimates and exclusions should be documented rather than hidden.
• Review the calculation: Check units, formulas, conversions and supporting files. Small spreadsheet errors can have a large effect on the final result.
• Prepare for verification where needed: Assurance and verification services may be needed when a PCF result will be published, used in a product claim, included in a tender or submitted to a customer that requires independently reviewed data.

Choosing a PCF assessment partner in Singapore

PCF work involves much more than entering electricity bills into a carbon calculator. The consultant needs to understand the product, the factory process and the reporting purpose. A study prepared for internal product improvement may not need the same evidence as a figure intended for a public claim or customer verification.
