Malaysian tanker operator AET is actively diversifying its fuel strategy by incorporating more alternative fuels into its fleet operations. In 2025, the company utilized a combined 3,200 metric tons of B24 and B30 biofuel blends across its vessels. Additionally, AET successfully completed its initial trial using liquefied biomethane (LBM) on one of its ships.
This move comes as AET expresses concerns regarding the broader shipping industry's transition to greener operations. The company points to increasing uncertainty surrounding the consistent availability of alternative fuels and the evolving, often unclear, regulatory landscape as major challenges. These factors could significantly complicate efforts to decarbonize maritime transport.
For freight forwarders and operations managers, this trend from carriers like AET signals a continued push towards sustainable shipping, but also highlights potential volatility in fuel choices and associated costs. The uncertainty in fuel availability and regulation could lead to fluctuating bunker prices for alternative fuels, impacting overall freight rates and potentially influencing carrier service reliability as they adapt to new operational requirements. Forwarders should monitor these developments closely to anticipate changes in vessel routing, capacity, and pricing structures, especially on routes where carriers are experimenting with new fuel types.
