A factory installs rooftop solar and announces that its operations now run on clean energy. A regional office buys a bundle of renewable energy certificates and reports 100% renewable electricity. A property group signs a power purchase agreement and describes its buildings as low-carbon. All three statements may be made in good faith. Not all of them will survive an auditor’s questions, and one of them may not be a renewable electricity claim at all.
The problem is rarely dishonesty. Electricity claims depend on rules that most operating businesses never encounter: who owns the environmental attributes attached to a megawatt-hour, where it was generated, when it was generated, and whether anyone else has already claimed it. Across Asia, those rules are being tightened at the same time as procurement options multiply. Understanding both movements is now part of running an energy strategy, not an afterthought for the sustainability team.
Generating, buying and claiming are three separate things
Every unit of electricity has two components that can be separated: the electrons, and the environmental attributes describing how those electrons were produced — technology, location, commissioning date, emissions rate, time of generation. Energy attribute certificates, often called renewable energy certificates, are standardised instruments issued to a unit of generation that carry those attributes and allow them to be tracked and retired.
This separation is why a company can generate solar power on its own roof and still lose the right to call its electricity renewable. If the attributes were sold to a third party, the electrons remain, but the claim does not. It is also why buying certificates in one country does not support a claim about consumption in another: attributes must come from the same market as the electricity they are applied to.
Greenhouse gas accounting reflects this. Under the Scope 2 Guidance published in 2015, companies operating in markets where contractual instruments are available report purchased-electricity emissions twice — once using the grid-average factor for the location, and once using the contractual instruments they hold. Buying certificates changes the second figure. It does not change the first. Companies that report a single number and describe it as their emissions from electricity have usually skipped a step.
Six routes, six different things you can say
The route a business chooses determines the strength of the claim it can make and the evidence it must retain. The table below sets out the practical differences.
| Procurement route | What it is | What it supports | Core evidence to keep |
|---|---|---|---|
| Self-generation on site | Solar or other generation owned by the company on its own premises | A direct consumption claim, provided the attributes have been retained and not sold | Metered generation data, contract terms confirming attribute ownership, export and import records |
| Physical power purchase agreement | Contract with a generator for delivered electricity, on site or through the grid | The strongest grid-based claim, because energy and attributes arrive together | Signed agreement, delivery and settlement records, attribute transfer clauses |
| Virtual or financial PPA | A financial arrangement that transfers price risk and conveys attributes only | An attribute claim; the company must still buy its physical electricity separately | Contract for difference terms, certificate issuance and cancellation records |
| Project-specific supply contract | Utility or retailer sources from named projects on the buyer’s behalf | A transparent claim tied to identifiable assets | Contract naming the projects, supplier attestation, cancellation statements |
| Retail green tariff | An off-the-shelf renewable product billed as a premium per kilowatt-hour | A weaker claim; the supplier may change the underlying projects during the term | Tariff terms, annual supplier disclosure of the projects and certificates used |
| Unbundled certificates | Certificates bought separately from the electricity supply | A claim only where the certificates come from the same market and are cancelled | Serial numbers, vintage, project commissioning date, cancellation confirmation |
Two points in this table are commonly misread. A virtual power purchase agreement is a financial instrument — a company holding one still purchases physical electricity from the grid and must account for it. And a retail green tariff, while legitimate, gives the buyer far less visibility than a project-specific contract, because the supplier can vary the underlying generation.
Five tests before a renewable energy claim is published
Before an energy statement reaches a report, a website or a customer questionnaire, it should pass five checks. Each corresponds to a principle that verification bodies apply.
- Ownership. Does the company hold the environmental attributes, in writing, for the volume it intends to claim? A generation asset alone proves nothing if the attributes were transferred elsewhere.
- Market boundary. Was the electricity generated in the same market as the consumption? Across Asia, countries are treated as separate markets. Certificates from one country do not decarbonise consumption in another.
- Timing. Does the vintage of the generation align with the consumption period being reported? Attributes generated years before or after the reporting year weaken the claim, and time-matching requirements are tightening.
- Exclusivity. Has anyone else claimed the same generation? A supplier meeting a compliance obligation, a landlord reporting building performance, or a broker selling the same attributes twice will all break the claim.
- Impact. Does the procurement do anything for the grid? A twenty-year agreement with a newly commissioned project and a one-off purchase of certificates from a decades-old asset are not equivalent, and reporting frameworks increasingly say so.
A claim that fails any of the first four is not conservative — it is unsupported. A claim that passes the first four but fails the fifth is defensible, but a company should not describe it as leadership.
What is changing across Asia
Three developments matter for businesses in the region.
Procurement options are widening. Malaysia’s Corporate Renewable Energy Supply Scheme, introduced in September 2024, allows corporate consumers to contract directly with renewable developers for electricity delivered through the national grid, with a system access charge paid to the grid operator. Access was extended to existing consumers from March 2025, and the Energy Commission revised the scheme’s guidelines at the end of December 2025 alongside changes to self-consumption solar rules. Similar third-party access and corporate sourcing mechanisms have been developing across Southeast Asia, which means the choice of route is now a genuine commercial decision rather than a default.
Certificate markets are established but uneven. Certificate systems are in routine use in China, India, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Thailand and Vietnam, with the International REC standard operating widely and several markets running national systems alongside it. Availability is not the issue. Quality of documentation is: many buyers hold an invoice but not the cancellation record that actually proves retirement.
Accounting rules are being revised. The Greenhouse Gas Protocol has consulted publicly on revisions to its Scope 2 Guidance that would require certificates used in market-based reporting to be matched to consumption on an hourly basis and sourced from generation deliverable to the consuming load, with load profiles, phased implementation and exemptions for smaller organisations under consideration. The first consultation closed at the end of January 2026, a second consultation is expected during 2026, and a final standard is planned for 2027. These are proposals, not requirements. But companies signing long-term contracts today are signing into the environment those rules will create.
Alongside this, the RE100 technical criteria updated in March 2025 already restrict what counts as a credible corporate claim: procurement must generally come from projects commissioned or re-powered within the previous fifteen years, with a 15% allowance and specific exemptions; certificate cancellation becomes a requirement in markets where certificates are in common use; and procurement from projects co-firing coal is excluded. Both rules apply from the 2027 disclosure cycle.
Five mistakes that undermine otherwise sound projects
- Confusing capacity with output. Installed kilowatts are a procurement fact. Generated kilowatt-hours are the performance fact, and only the second supports a claim.
- Reporting one Scope 2 figure. Where contractual instruments exist, the grid-average figure and the contractual figure are both part of the picture. Reporting only the flattering one invites challenge.
- Assuming certificates offset on-site fuel use. Certificates are grid instruments. They do not address emissions from fuel burned on the company’s own premises.
- Losing the cancellation trail. Certificates must be retired by or on behalf of the claiming company, with records identifying what was cancelled. A purchase order is not proof of retirement.
- Describing the company rather than the electricity. “Our electricity in Malaysia was matched with certificates from a named solar project” is a claim. “We are a green company” is a slogan, and increasingly a liability.
When an energy result becomes an exceptional achievement
Most renewable energy work is not remarkable, and it does not need to be. It needs to be accurate. But some organisations do produce outcomes that are genuinely unusual in scale — an installation programme delivered at a volume no comparable company has reached, a manufacturing site achieving a level of self-generation that is rare for its industry, a participation-based environmental initiative involving numbers that can be independently counted.
It is worth separating the forms of external validation that can attach to such an outcome, because they answer different questions and none replaces another. Regulatory approvals confirm that an installation is legal and safe. Assurance confirms that a reported number was prepared properly. Certification confirms that a system or product meets a defined standard. Record recognition answers something narrower: whether a measurable achievement is exceptional when compared with others.
That last category is where a platform such as Asia Record operates. Its register of recognised record holders spans companies and organisations across the region whose achievements have been submitted with supporting evidence and reviewed before recognition, and it illustrates the standard of documentation involved. For a business whose environmental or community programme has produced an outcome that is specific, measurable and independently verifiable, understanding the Asia Record application process is a reasonable next step — and the same evidence file assembled for reporting purposes is usually the file that supports it.
The sequence matters, though. Recognition is what a measurable achievement can earn afterwards. It is not a substitute for compliance, assurance or certification, and it is not a shortcut around the five tests above. An organisation that cannot yet document attribute ownership and cancellation for its own electricity is not ready to present that achievement to anyone.
The evidence file to build first
Whatever route a company chooses, one folder should exist before any public statement is made. It contains: total electricity consumed by site and by country; the contracts governing each renewable supply; documentation of who holds the environmental attributes; certificate records including serial numbers, vintages, project commissioning dates and cancellation confirmations; metered generation data for any owned assets; and both Scope 2 figures with the emission factors used and their sources.
That file is unglamorous, and it is the difference between a claim a company can defend and a sentence it will quietly delete next year. Businesses across Asia are moving quickly on renewable procurement, which is the right direction. The organisations that will benefit most are those whose paperwork moves at the same speed as their panels.
