As maritime stakeholders evaluate zero-carbon fuel options, the verification of carbon intensity, as well as the full lifecycle impact of these fuels, will present a significant challenge.

Ammonia and hydrogen, two of the most promising long-term alternative fuel candidates for shipping's energy transition, are often produced using fossil fuels.

This situation poses a dilemma for fuel purchasers in distinguishing between a fuel produced using non-renewable methods and one mixed with fuel molecules produced using green sources.

Modern technology could lift the barrier of tracing the true carbon intensity to prevent mislabelling and illicit blending.
