Webinar: GHG Methodologies for PtX from a Policymaker’s Perspective
In this webinar, we examined how governments in Power-to-X producing countries can support their domestic industries in meeting complex international greenhouse gas (GHG) accounting standards to unlock global export markets. Framed from a policymaker’s perspective, the session explored the rapidly growing landscape of compliance requirements, including the EU RFNBO, ICAO CORSIA, and the IMO’s Life Cycle Assessment (LCA) Guidelines, and outlines actionable steps for national governments to reduce compliance burdens on producers. Additionally, the recording features expert insights on real-world regulatory developments, specifically highlighting the rollout of the South African Green Hydrogen Standard and ongoing updates to the IMO’s 2024 LCA Guidelines.

Key Takeaways for Policymakers
Make reliable national data publicly available: Provide data on national and bidding zone grid emission factors (including transmission and distribution losses), as well as renewable energy generation and consumption.
Build registries & certification infrastructure: Establish interoperable proof-of-origin and proof-of-production registries, alongside accredited verification bodies.
Align rather than add: Prioritise alignment with priority export market standards or pursue mutual recognition. An ever-growing number of standards and methodologies risks placing an additional burden on PtX producers.
Promote harmonisation and signal Article 6 readiness: Advocate international convergence while balancing environmental rigour with practical implementation. Signal willingness to use Article 6.4 and encourage project developers to explore its opportunities.
PtX GHG Methodologies Guidebook and Calculators
The webinar also introduces a PtX GHG Methodologies Guidebook and PtX GHG Intensity Calculators, which offer a stocktaking and comparison of different standards and GHG emissions accounting methodologies for Power-to-X products, from ICAO CORSIA to EU RFNBO.
