Amazon has invested in Brazil-based GranBio to develop technology that converts forestry waste and construction debris into sustainable aviation fuel (SAF). The partnership aims to increase SAF supply for Amazon's air cargo operations and the broader aviation industry, which faces limited production capacity. GranBio's process breaks down woody biomass into drop-in fuels that work with existing engines and infrastructure, avoiding food crops or vegetable oils. This investment is part of Amazon's Climate Pledge to reach net-zero emissions by 2040. The company co-founded the Sustainable Aviation Buyers Alliance and procured 3.7 million gallons of blended SAF in 2024. By backing next-generation fuel pathways, Amazon seeks to demonstrate demand for solutions that can scale across the sector. The article details the technology and Amazon's broader strategy to cut transport emissions.
