Gold Standard is opening a public consultation on Version 5.0 of the Reduced Emissions from Cooking and Heating (TPDDTEC) Methodology. This major update realigns the standard with the Paris Agreement by sharpening its scope and enhancing baseline rigor.
Key Highlights
· Scope Refinement: TPDDTEC V5.0 now focuses exclusively on unmetered technologies (e.g., biomass stoves). All metered devices (electric, biogas, etc.) are now covered under the MECD methodology.
· 5-Step Baseline: Introduces a structured, mandatory process for setting baselines, ensuring consistency and transparency.
· Ambition & Safeguards: Integrates "Downward Adjustment Factors" (DAF) to align with Net-Zero goals, per-capita baseline caps to prevent over-crediting, and mandatory adjustments for the Hawthorne Effect.
Transition for Existing Projects
· Gap Validation: A streamlined "Mid-Crediting Period" pathway allows projects to adopt new integrity rules (e.g., DAF, Caps) without full re-validation.
· Grace Period: Projects can continue distributing devices matching their original technical specifications until 01 January 2028. However, new accounting rules apply immediately for 2026+ vintages.
Evidence-Based Updates
The update is supported by a Supplementary Information package verifying the scientific basis for new leakage defaults, embodied emissions factors, and lock-in risk assessments for fossil-fuel technologies.
