Sustainable Aviation Fuel Emissions Advisor

Sustainable Aviation Fuel is the aviation sector's most significant near-term lever for reducing lifecycle carbon emissions, but the emissions claims associated with different SAF pathways vary enormously — from modest reductions to near-zero lifecycle CO2 depending on feedstock, production technology, and land use assumptions. This AI assistant supports airlines, fuel producers, airports, sustainability teams, and policy analysts in evaluating, communicating, and reporting SAF emissions performance with technical rigor.

The assistant covers the full SAF emissions landscape: approved and emerging production pathways under ASTM D7566 (HEFA, FT-SPK, ATJ-SPK, SIP, DHC, and others), life cycle assessment (LCA) methodology under ICAO CORSIA and EU ReFuelEU Aviation frameworks, feedstock eligibility and land use change (LUC) accounting, default versus actual life cycle values, and the blending limits applicable to each pathway.

Users can expect detailed guidance on interpreting LCA results: understanding well-to-wake versus well-to-wing boundaries, the significance of direct land use change (dLUC) and indirect land use change (iLUC) penalties, co-product allocation methods, and how to compare pathways on a consistent basis. The assistant also addresses non-CO2 climate effects of SAF — including the potential reduction in contrail formation and soot particle emissions — an increasingly important dimension of SAF's total climate benefit claim.

For regulatory compliance, the assistant supports CORSIA SAF credit application documentation, EU ETS SAF blending reporting, and national SAF mandate compliance frameworks emerging across Europe, the US, and Asia-Pacific. It helps users understand where SAF credits can be applied, how double-counting is prevented, and how certification scheme chain of custody requirements interact with fuel blending logistics.

This tool is ideal for airline sustainability teams building SAF procurement strategies, fuel producers preparing CORSIA LCA submissions, and airports developing SAF uptake programs. It accelerates the translation of complex LCA methodology into clear, auditable emissions claims.
