Tool 10 helps renewable energy projects in developing markets apply high-integrity accounting despite real-world data constraints.
Renewable-energy projects in countries with limited electricity data will have a clearer route to meet high-integrity carbon-accounting requirements under a new tool published by Gold Standard.
Currently, fewer than 15% of host nations globally have the digital infrastructure required by the preferred approaches in the latest UNFCCC grid-emissions methodology's data requirements, an independent assessment commissioned by Gold Standard has found.
In response, Gold Standard has published Tool 10 –Technical Addendum to the A6.4 Grid Emission Factor Tool (A6.4-AMT-007). The mandatory technical overlay supports project developers applying the UNFCCC Article 6.4 Methodological Tool "Emissions from electricity generation and consumption" under Gold Standard for the Global Goals (GS4GG) in contexts where high-resolution data or timely administrative reporting are not yet available.
“Research reveals a gap between high-integrity accounting requirements and real-world data constraints: fewer than 15% of countries can currently meet the current methodological approach, leaving a vital source of carbon finance inaccessible in some of the countries that need it most. Tool 10 provides a time-bound, evidence-based pathway for projects to apply Article 6.4 requirements where high-resolution data is not available, while preserving safeguards for environmental integrity.
This is what a genuinely equitable transition to net-zero looks like: rigorous and adapted to reflect the conditions of the real world.”

The UNFCCC methodology establishes a robust framework for grid-emissions accounting, including high-resolution hourly data requirements and dynamic baseline modelling. Tool 10 supports application of the methodology in more contexts by introducing three provisional measures:
1. Data-Readiness Waiver and Intermittency Discount
Where hourly dispatch data is unavailable, eligible projects may use annual data with a scientifically bounded 10% conservativeness discount. This ensures that projects are not excluded in regions where high-resolution data infrastructure is not yet available.
2. Infrastructure Inertia Cap and Lag Buffer
For vintage-decay factors used to estimate the annual decrease in the Build Margin, eligible projects may apply a 5% ceiling and a 24-month administrative lag buffer. These safeguards help prevent mathematically implausible baseline outcomes caused by old statistics and unconstrained linear decay calculations. The tool also applies a floor so that the adjusted emission factor cannot become negative, resulting in more stable and auditable values.
3. Battery Energy Storage Systems Safe Harbour
The latest UNFCCC methodology applies stricter conditions to intermittent generation sources but does not clearly define whether pairing a project with a Battery Energy Storage System (BESS) changes its classification. The addendum establishes conditions under which intermittent activities integrated with adequately sized BESS can be treated as “non-intermittent” generation sources, providing greater clarity for hybrid renewable energy activities.
Gold Standard developed Tool 10 following technical inputs submitted during the finalisation of A6.4-AMT-007 and an independent assessment by subject matter experts of the tool’s operational and financial implications in emerging markets. The addendum reflects the Paris Agreement's principle of Common but Differentiated Responsibilities and Respective Capabilities, balancing rigorous accounting requirements with the practical realities faced by activity developers and host countries.
Notes
- An independent assessment, supported by global infrastructure data (Ember, 2024), notes that fewer than 15% of host nations globally possess the digital infrastructure needed to produce the high-resolution, machine-readable hourly dispatch and curtailment data required by the A6.4-AMT-007 Tool. Official sovereign documents, such as India’s Central Electricity Authority (CEA) CO₂ Database User Guide (v21.0), explicitly state that the grid currently lacks the data required to apply the tool's preferred dispatch methods. Countries without this infrastructure include Türkiye, India, China, Vietnam, LDCs and SIDS. You can read the study here.
