Verra has released VM0053, the first carbon credit methodology specifically for low-carbon fuels in shipping. The framework allows vessels using e-fuels like green hydrogen, ammonia, e-methanol, and e-diesel to generate verified carbon credits, creating a new revenue stream to help offset the high cost of clean marine fuels. The methodology applies to both new and existing ships operating anywhere in the world. The framework was developed by Iino Kaiun Kaisha, Grutter Consulting, and Verra, and it includes rules for additionality, lifecycle emissions, and avoiding double counting. It aims to bridge the cost gap between conventional bunker fuels and alternatives, which has been a major barrier to adoption. Shipping accounts for about 3% of global emissions but carries over 80% of world trade by volume. This is a practical step toward monetizing emissions reductions in a hard-to-abate sector. The methodology could attract investment into e-fuel production and accelerate uptake among shipowners facing tightening IMO regulations. It gives the voluntary carbon market a real tool to support maritime decarbonization, not just future vessel designs but the existing fleet as well.
