Professor Johan Sulaeman highlights the potential of geological carbon credits (GCCs) as a critical enabler of aviation’s decarbonisation pathway. As a hard-to-abate sector, aviation will continue to face persistent residual emissions, even as sustainable aviation fuel (SAF) scales over time. GCCs offer a high-integrity solution to neutralise these emissions through permanent carbon storage, aligning with the long atmospheric lifetime of aviation-related CO₂ and thereby addressing a structural gap that cannot be eliminated through technological and fuel substitution alone. With significant geological storage potential in Southeast Asia, and strong market infrastructure, Singapore is well positioned to anchor regional carbon market development and integrate GCCs into a credible, long-term decarbonisation strategy.
