As part of the ABS 2024 Outlook, “Beyond the Horizon: Carbon Neutral Pathways and Transformational Technologies,” ABS developed the Greenhouse Gas (GHG) Abatement Cost (GAC) Index to statistically assess the trade-offs between cost and GHG emission savings, specifically focusing on the well-to-wake approach.

Based on the GAC analysis of the three developed scenarios (e-fuels high uptake, biofuels high uptake and blue fuels high uptake), a projected ranking of the different fuel pathways’ cost-effectiveness in 2050 was calculated.

According to ABS’ GAC methodology and current fuel prices, biofuels and blue fuels will have a lower carbon abatement cost compared to others.
