As Singapore pushes toward a low-carbon future, the country’s industrial and manufacturing sectors face growing pressure to decarbonise without compromising output or profitability.
Electricity remains one of the largest contributors to Scope 2 emissions — those that result from purchased energy rather than direct fuel use — and for most factories, achieving net-zero operations is not immediately feasible.
That’s where green energy credits come in. These certificates allow you to match your factory’s power consumption with renewable energy produced elsewhere, offering a verifiable and flexible way to reduce your Scope 2 footprint. But like any sustainability tool, their value depends on how strategically you use them.
This guide explores four proven strategies Singapore factories can adopt to track, procure, redeem, and partner effectively — maximising both sustainability outcomes and long-term operational advantage.
Key Takeaways
- Singapore factories can significantly cut their Scope 2 emissions by using green energy credits strategically — tracking energy use accurately, aligning procurement with operational goals, and ensuring transparent redemption.
- Adopting data-driven monitoring and partnering with accredited providers allows manufacturers to integrate renewable energy into their operations efficiently while maintaining compliance and cost control.
- By turning green energy credits from a compliance tool into a long-term sustainability strategy, factories can strengthen their ESG credibility, attract responsible investors, and lead Singapore’s transition toward low-carbon manufacturing.
1. Track Your Energy Footprint with Data-Driven Precision
Before you can offset carbon emissions, you need to understand them. Tracking your electricity usage accurately is the foundation of any credible green energy credit strategy.
In many factories, energy data is fragmented — spread across different production lines, utility accounts, and time periods. Without centralised monitoring, it’s nearly impossible to calculate Scope 2 emissions precisely or forecast how many credits you need.
Start by deploying smart meters and digital monitoring tools that capture real-time energy consumption across your facility. Integrate these with energy management systems that align with recognised frameworks such as ISO 14064 or ISO 50001. These systems help you:
- Identify high-load processes that contribute most to emissions
- Benchmark monthly or quarterly consumption patterns
- Forecast future demand for renewable energy credits with accuracy
You might, for example, imagine an electronics manufacturer in Jurong that operates 24/7 production lines. By installing sub-meters across its testing and packaging departments, it might discover that idle equipment consumes, say, a tenth of the total power.
With that insight, the company recalibrates its operations and predicts its annual REC requirements more precisely — reducing both cost and waste.
The lesson: the more granular your data, the more strategic your credit procurement becomes.
2. Procure Green Energy Credits That Align with Your Operational Goals
Once you have a clear energy profile, the next step is deciding how to procure your green energy credits. This is where many factories either overpay or under-leverage the benefits of renewable certification.
Understand Your Options
There are generally two ways to buy RECs:
- Spot RECs — bought on demand at market prices. They’re flexible and ideal for covering short-term gaps or pilot sustainability programmes.
- Contracted RECs — secured through longer-term agreements, typically one to three years. These provide price stability and predictable supply, supporting annual reporting consistency.
If your energy consumption varies seasonally or you’re just beginning your sustainability journey, spot purchases may suffice. However, if you have a stable baseline of electricity use, contracted RECs offer better long-term cost control and audit traceability.
Prioritise Regional Sourcing
In Singapore’s tightly regulated market, regionally sourced certificates — such as those from accredited I-REC projects in Malaysia or neighbouring ASEAN countries — should comply with SS 673:2021, the Singapore Standard that governs the procurement, tracking, and verification of renewable energy certificates.
Adhering to this standard ensures that the renewable energy you purchase is transparently traceable to recognised sources within the regional grid.
For example, a precision-engineering firm in Tuas might source local I-RECs from solar projects in Johor and complement them with wind RECs from Thailand. This balanced mix supports corporate decarbonisation goals while aligning with stakeholder expectations for traceable, regionally relevant sustainability claims.
Vet Your Providers
Not all green energy credits carry equal assurance. To avoid double-counting or unverifiable claims, work only with authorised providers and platforms that maintain registry transparency. Confirm that each credit includes unique serial numbers traceable through recognised systems such as the I-REC Standard.
A trusted partner can also advise on pricing trends and recommend optimal purchase timing to mitigate market volatility.
3. Redeem and Report Transparently to Strengthen Your ESG Profile
Buying green energy credits is only half the journey — the real impact comes when you redeem and report them properly. Transparent redemption ensures that each green energy certificate is retired in your name, confirming that no one else can claim the same renewable benefit.
It’s also worth noting that under SS 673:2021, RECs are voluntary market instruments, not regulatory permits. They don’t replace compliance obligations but instead serve as credible proof of voluntary action toward sustainability and carbon reduction.
Redeem with Intent
Timing matters. Redeem your credits in the same reporting period as your energy use to maintain carbon accounting accuracy. This alignment strengthens your sustainability disclosures and supports verification under global standards such as the Greenhouse Gas (GHG) Protocol’s Scope 2 Guidance.
Let’s take a food-processing facility as an example. It might purchase its 2025 RECs in Singapore early in the year but hold redemption until Q4, once its total electricity consumption is confirmed. This can ensure that credits match actual kilowatt-hour use, avoiding over- or under-reporting.
Integrate RECs into Corporate Reporting
Once redeemed, your certificates become part of your company’s carbon narrative. Incorporate REC data into your annual sustainability reports, ESG dashboards, or CDP disclosures. Highlight key details such as:
- Total MWh of renewable energy matched through RECs
- Geographical source of generation
- Reduction in Scope 2 emissions year-on-year
Such transparency reassures investors, clients, and regulators that your emissions claims are legitimate and measurable.
Use Digital Traceability
Many registries today provide digital audit trails where redemption events are timestamped and publicly visible. These tools make it easier to demonstrate accountability without relying solely on internal documentation.
When shared responsibly, this visibility can even enhance your brand. Stakeholders increasingly value manufacturers who not only meet compliance requirements but also communicate sustainability progress openly.
4. Partner Strategically for Long-Term Energy Transition
Managing green energy credits in isolation can be resource-intensive. Partnering with the right sustainability and energy-tracking experts helps your factory move from ad-hoc compliance to strategic advantage.
Work with Accredited Providers
Collaborating with an accredited REC provider ensures that every stage — from sourcing to redemption — follows global best practices. The right partner helps you navigate certificate registries, verify documentation, and align procurement cycles with your sustainability calendar.
A provider like Asiarecs, for example, supports businesses across Singapore and Malaysia with complete REC lifecycle management. From identifying suitable regional projects to facilitating transparent redemption, such partners reduce administrative load while ensuring full compliance.
Combine Credits with On-Site Renewable Projects
If your factory is exploring on-site solar, consider bundling physical generation with green energy credits. For instance, you might install rooftop solar panels with the goal of covering 20% of your load while purchasing RECs to offset the remaining 80%. This hybrid model allows immediate decarbonisation while larger capital projects scale over time.
Consider this real-world scenario: If you’re operating a logistics hub in Tuas, you could partner with a solar developer for partial on-site generation and secure the rest through regional I-RECs. If done properly, you can achieve predictable renewable coverage at a stable cost.
Build Corporate Alliances for Scale
Some multinational manufacturers achieve economies of scale by forming consortiums or joint procurement groups for green energy credits. This approach not only reduces per-unit cost but also strengthens collective bargaining power with renewable developers.
While this model may not suit every factory, it highlights the broader principle: sustainability gains traction faster when approached collaboratively rather than individually.
Plan Beyond Compliance
The end goal isn’t just meeting regulatory expectations or ticking ESG boxes — it’s positioning your business for the energy transition decade ahead. Factories that treat green energy credits as part of a long-term transformation strategy gain early access to innovation opportunities, green financing, and preferential procurement from sustainability-minded clients.
Why These Green Energy Credit Strategies Matter Now
Singapore’s Green Plan 2030 sets an ambitious course toward a low-carbon future—one where clean energy adoption and transparent sustainability reporting are essential, not optional.
For factories and industrial players, aligning with this direction is no longer just about meeting compliance standards; it’s about maintaining competitiveness, market access, and investor confidence in a rapidly decarbonising economy.
Supporting Singapore’s Green Transition
Under the Green Plan 2030, Singapore aims to accelerate its shift toward renewable energy through regional power grids, carbon markets, and greater corporate accountability. This national agenda directly impacts manufacturing and energy-intensive sectors.
Factories that integrate renewable energy tracking mechanisms—such as Renewable Energy Certificates (RECs)—demonstrate alignment with Singapore’s national sustainability goals. By adopting these tools early, manufacturers can reduce their carbon footprint and stay ahead of upcoming regulations on emissions disclosure and clean energy sourcing.
Meeting Global Supply Chain Expectations
Supply-chain sustainability has become a defining factor for export competitiveness. Major multinational buyers, especially in electronics, pharmaceuticals, and consumer goods, now require verifiable carbon disclosure and renewable energy sourcing evidence from their suppliers.
Factories that can show proof of renewable energy use through traceable RECs not only meet these evolving requirements but also gain a competitive advantage in global procurement.
In contrast, suppliers unable to verify clean energy usage risk exclusion from preferred vendor lists or international sustainability frameworks such as the Science Based Targets initiative (SBTi) and CDP Supply Chain programme.
Strengthening Investor and Financial Confidence
Beyond supply chains, the financial landscape is shifting. Banks and investors are intensifying ESG scrutiny, favouring businesses with measurable, third-party–verified climate action.
Documented REC redemption serves as tangible proof of renewable energy contribution, making it easier for companies to access sustainability-linked loans, green bonds, or other forms of environmentally aligned capital. In a tightening investment environment, credibility and data-backed transparency are key differentiators.
Securing Long-Term Advantage
By acting now—before stricter carbon regulations and cost mechanisms are implemented—factories can future-proof their operations.
Early adoption of renewable tracking and reporting systems not only reduces exposure to future carbon costs but also builds a trustworthy sustainability record that enhances brand reputation, operational resilience, and investor trust.
Bringing These Green Energy Credit Strategies Together
The path to decarbonisation isn’t linear, but it’s manageable when approached strategically. To recap:
- Track precisely — establish accurate energy baselines through smart monitoring and data management.
- Procure smartly — choose between spot and contracted RECs based on your operational profile, prioritising regional traceability.
- Redeem transparently — retire certificates responsibly and report them clearly in your sustainability documentation.
- Partner strategically — collaborate with accredited providers and integrate RECs into long-term renewable planning.
Each step strengthens the credibility of your environmental claims and positions your factory for sustained competitiveness in an increasingly low-carbon marketplace.

Frequently Asked Questions
Can small and medium-sized factories in Singapore buy green energy credits?
Yes, SMEs can purchase green energy credits just like large corporations. Accredited providers such as those operating under the I-REC framework make it easy for smaller factories to buy and redeem credits according to their actual energy use.
What is the difference between green energy credits and carbon credits?
Green energy credits represent proof that electricity has been generated from renewable sources, while carbon credits offset emissions from any activity, not just power generation. Both contribute to decarbonisation, but green energy credits directly address Scope 2 emissions linked to purchased electricity.
Do green energy credits expire if they are not redeemed?
Most green energy credits have a validity period linked to the reporting year in which the renewable energy was produced. Redeeming them within that timeframe ensures accurate emissions accounting and compliance with sustainability reporting standards.
How are green energy credits verified?
Each green energy credit carries a unique identification number recorded on an official registry, such as the I-REC Standard. This system prevents double-counting and ensures that every certificate corresponds to a verified megawatt-hour of renewable electricity.
Can factories use green energy credits alongside on-site solar or renewable systems?
Absolutely. Many factories combine on-site renewable generation with purchased green energy credits to achieve full coverage of their electricity use. This hybrid approach allows them to accelerate their sustainability goals even when physical renewable output doesn’t meet total demand.
