Sustainable aviation fuel (SAF) can reduce aviation greenhouse gas emissions by up to 80% but faces adoption barriers including high costs and limited availability at airports worldwide. Book and claim mechanisms allow companies to access SAF's emission reduction benefits even when it's not physically available at their location, bridging the gap between concentrated supply and global demand. Shell's Avelia platform uses blockchain to track SAF environmental attributes across the supply chain, while organizations like DHL are using book and claim to meet science-based decarbonization targets. Industry experts emphasize the need for coordinated ecosystem adoption and standardization, urging companies to act now rather than wait for perfect guidelines.
