The Independent Standards Board (ISB) and Technical Working Group (TWG) have effectively decided the fate of the 2015 Scope 2 market-based method: annual matching without spatial deliverability is being phased out. For Malaysian companies aligning with the National Sustainability Reporting Framework (NSRF) and international disclosure baselines, this transition will invalidate the bulk of current corporate renewable claims if procurement strategies do not adapt to hourly tracking and physical deliverability.

The End of “Anywhere, Anytime” Green Power Accounting
For more than a decade, corporate Scope 2 market-based accounting under the 2015 GHG Protocol Scope 2 Guidance allowed companies to claim market-based emissions reductions using contractual instruments like Energy Attribute Certificates (EACs), Renewable Energy Certificates (RECs), and Power Purchase Agreements (PPAs) matched on an annual aggregate basis. Under that legacy regime, an enterprise operating in an emissions-intensive grid could purchase certificates generated hundreds of miles away (or across disjointed transmission regions) and claim net-zero electricity emissions.
The GHG Protocol Secretariat, the Technical Working Group (TWG), and the Independent Standards Board (ISB) have acknowledged that this disconnect between contractual purchasing and real-world grid physics undermines reporting integrity.
The public consultation (concluded in January 2026) revealed a split between two distinct theories of change:
- System-Level Decarbonisation (Granular / Hourly): Requiring clean electricity to be matched hourly, delivered on the physically connected grid, and sourced from newly built assets (incrementality) creates direct price signals where generation is scarce.
- Voluntary Market Liquidity (Broad / Annual): Preserving annual matching and wide geographic boundaries keeps administrative barriers low, encouraging widespread corporate capital deployment.
Rather than picking an immediate winner, the ISB directed the standard toward an orderly phase-out.
Deconstructing the ISB’s Direction: Dual-Method Framework
Following the TWG’s technical evaluations in mid-2026, the ISB established the direction of travel for the market-based accounting mechanism:
1. Market-Based Method 1: The High-Integrity Standard
Method 1 introduces three non-negotiable accounting pillars:
- Hourly Matching: Clean energy generation must be matched to operational consumption within the same hourly settlement window (24/7 carbon-free energy).
- Deliverability: Clean power must originate within the same deliverable transmission boundary or market area where the reporting company draws power.
- Incrementality: Sourcing must come from clean energy installations built within a defined recent timeframe, preventing corporate claims from riding on historical, pre-existing capacity.
2. Market-Based Method 2: The Sunsetting Bridge
Method 2 preserves the 2015 criteria to maintain near-term feasibility. However, companies applying Method 2 will be required to disclose that status transparently, warning capital markets and supply-chain procurers that their reported emissions do not reflect hourly temporal or local spatial delivery.
3. Phased Obsolescence
The ISB’s direction specifies that companies should adopt Method 1 during an interim window, shall explicitly disclose whether Method 1 or Method 2 is applied, and, after a designated cut-off date, shall apply Method 1 if qualifying data is available.
Interlocking Standards: The Role of the Actions and Market Instruments (AMI) Workstream
What happens to energy contracts that fail Method 1’s strict deliverability or hourly criteria?
The GHG Protocol is actively integrating Scope 2 with the parallel Actions and Market Instruments (AMI) workstream. The proposed multi-statement reporting framework splits corporate climate disclosures into distinct statements:
Market-Based GHG Inventory Statement: Reserved exclusively for contractual instruments that fulfill strict physical and quality accounting criteria (such as Method 1).
GHG Impact Statement: Quantifies the estimated avoided emissions or system-level real-world impacts of market interventions outside the immediate boundary.
Non-GHG Indicators Statement: Tracks procurement spends, capacity investments, and contractual commitments that signal decarbonisation effort without claiming direct inventory deductions.
If an off-grid green tariff or unbundled attribute fails deliverability criteria, companies can no longer subtract it from their market-based Scope 2 inventory total. Instead, it will migrate into supplementary impact or activity reporting.
Why Malaysian Corporates and Exporters Must Prepare Now
Malaysian organizations cannot afford to dismiss this as a distant debate happening elsewhere. This technical overhaul intersects directly with domestic reporting mandates and international market access:
- Alignment with the NSRF and IFRS S2
Under the National Sustainability Reporting Framework (NSRF), Malaysian public listed companies and large non-listed entities are aligning disclosures with IFRS S2 Climate-related Disclosures. As highlighted in our analysis on how NSRF sustainability assurance obligations demand reliable internal controls and evidence, Scope 2 emissions will face external scrutiny.
When independent verifiers inspect Scope 2 numbers under ISO 14064-1:2018 corporate inventory standards, dual-method disclosures will require demonstrable evidence trails down to meter records, contract terms, and supplier retirement registries.
- Trade Exposure and Embedded Emissions
For industrial manufacturers supplying multinationals or exporting into regulated jurisdictions, emissions accounting is tied to cross-border viability. As examined in our guide on CBAM verification and accreditation for Malaysian producers, international frameworks demand verifiable actual emissions rather than unverified proxy assumptions.
If your European or multinational buyers require Scope 2 calculations compliant with revised GHG Protocol rules, relying on unbundled, geographically disconnected green premiums will expose your products to calculation disputes and carbon-adjustment penalties.
Comparison: Current Scope 2 Guidance vs. The Incoming Framework
Accounting Attribute | Legacy Guidance (2015 Scope 2) | Incoming Dual Method (Method 2 Bridge) | Future Joint Standard (Method 1 Standard) |
Temporal Granularity | Annual aggregate matching | Annual aggregate matching (permitted temporarily) | Hourly matching (24/7 matching) |
Geographic Boundaries | Broad country or regional boundaries | Broad regional boundaries (with caveat disclosures) | Deliverable transmission region or physically connected grid |
Asset Age / Incrementality | Not required | Not required | Specified plant vintage criteria |
Disclosure Obligation | Report market-based total | Mandatory disclosure of Method 1 vs. Method 2 | Method 1 mandatory (Method 2 retired or reallocated to AMI statements) |
Audit & Assurance Posture | Registry retirement certificates | Registry certificates + boundary justification | Time-stamped generation vs. consumption audit logs |
The Strategic Roadmap to 2028
The revision process follows a structured timeline leading to the consolidated standard:
[Late 2026] ────► Scope 2 TWG In-Person Workshop & Drafting Consensus
│
[Q2 2027] ────► Consolidated Public Consultation (Scope 1, 2, 3 + AMI)
│
[Q4 2028] ────► Official Publication of the Joint GHG Protocol-ISO Corporate Standard
With the consolidated draft arriving in Q2 2027 and final release scheduled for Q4 2028 alongside ISO standards, organizations that wait for official publication will face acute capacity and contractual deficits. Power purchase agreements and renewable contracts signed today run 5 to 15 years; entering contracts based on obsolete 2015 criteria creates locked-in compliance liability.
Action Plan for Sustainability and Energy Leads
- Audit Existing Renewable Energy Contracts: Review corporate PPAs, supply agreements, and utility green tariffs. Flag contracts lacking time-stamping, regional deliverability, or generation vintage data.
- Upgrade Data Infrastructure: Move energy monitoring from monthly aggregate utility bills to smart-meter, interval-level consumption logging capable of supporting hourly accounting.
- Engage Utilities and Grid Operators: Advocate for granular, hourly attribute tracking mechanisms within national energy exchanges and green electricity tariffs.
- Stress-Test Location-Based Emissions: Because the dual-reporting framework retains location-based Scope 2 reporting as a baseline, focus on physical on-site energy efficiency and direct behind-the-meter generation to insulate against changes in market-based calculation rules.
