Arizona provides an favorable climate for both extensive flight infrastructure and algae farms. Implementing algal biofuels offers notable environmental benefits, including high growth efficiency, carbon sequestration potential, and lower greenhouse gas emissions compared with similar alternatives. Their implementation is currently constrained by technical limitations with accessing water, a scarce resource in Arizona, and meeting the fuel demands of the thriving aviation industry. This research identifies key policy gaps hindering progress toward sustainable aviation fuel, such as the expiration of the U.S. Farm Bill, limited gray water regulations, and underutilization of tax incentives provided through the Inflation Reduction Act. To address these challenges, the policy brief proposes a series of integrated policy recommendations that aim to reform water access laws, biomass crop subsidies, aviation fuel tax exemptions, carbon sequestration tax credits and aviation research & development tax credits. This approach offers a scalable model that could support climate action, economic resilience, energy independence, and long-term global transportation.
