Malaysia Airlines' parent company says it may add a green tax to tickets as sustainable aviation fuel (SAF) remains far more expensive than conventional jet fuel. The airline group is looking at fleet renewal and SAF purchases, while Singapore is already set to introduce a government-mandated green aviation tax in January 2027. Aviation accounts for about 2.5% of global carbon emissions, and SAF could cut around 65% of industry emissions if production scales up. SAF is currently under 1% of global jet fuel use, and feedstocks like used cooking oil and agricultural waste are limited. The article makes clear that airlines cannot simply pass the full cost to passengers without hurting demand. The open question is whether a green tax will be tied to actual fuel purchases or just become another fee. For carbon market watchers, the useful detail is how Malaysia prices SAF against conventional fuel and whether government policy will support production capacity.
