California’s New Approach to Aviation Decarbonization: What It Means for the Future 
 
In a surprising turn of events, the California Air Resources Board (CARB) recently decided to withdraw its proposal to mandate the use of low-carbon jet fuel through its Low Carbon Fuel Standard (LCFS) program. This decision has sparked significant debate, as California was poised to become a global leader in decarbonizing the aviation sector—a move that many viewed as critical in the fight against climate change. 

The Decision Explained 

Initially, CARB’s proposal aimed to require jet fuel suppliers to incorporate more sustainable aviation fuels (SAF) into their offerings, thereby reducing the carbon footprint of air travel. However, CARB retracted this plan, citing concerns that the market-based program could allow suppliers to bypass actual decarbonization efforts by purchasing credits from other entities with surplus credits to sell. This explanation has left many scratching their heads, as the credit system is designed to incentivize emissions reductions, whether directly by the regulated entities or indirectly through the purchase of credits. 

Potential Underlying Issues 

The withdrawal has raised questions about what might have driven this decision. One possible factor is the aviation industry’s significant pressure against the mandate, coupled with fears of potential lawsuits challenging California’s authority to enforce such regulations. The airline industry has argued that federal laws preempt the state from mandating any form of decarbonization of jet fuel. However, legal experts suggest that these fears may be overstated. 

Three federal statutes are often cited in preemption concerns: the Clean Air Act, the Airline Deregulation Act, and the Federal Aviation Act. Yet, there appears to be legal room for California to regulate jet fuel under the LCFS without directly conflicting with these federal laws. For example, the Clean Air Act governs emissions standards for airplane engines but does not prevent states from regulating the fuels used in those engines. Similarly, while the Airline Deregulation Act limits state interference in airline prices, routes, and services, a fuel mandate might not necessarily cross that line unless it significantly impacts these economic factors. 

Why It Matters 

The aviation sector is one of the hardest to decarbonize, and policy-driven initiatives are crucial to driving the necessary changes. While technologies like hydrogen, e-fuels, and battery-powered flight are making progress, they are not yet viable for large-scale, long-term use. In the meantime, SAFs—blended with conventional jet fuels—offer a more immediate solution for reducing the sector’s carbon footprint. Governor Gavin Newsom had directed CARB to set an ambitious 20% clean fuels target for aviation, reflecting the urgency of addressing aviation emissions. 

California’s LCFS program could have been a powerful tool to not only encourage the use of SAFs but also to send a clear signal to the aviation industry that the state is serious about its climate commitments. By stepping back from this mandate, California risks slowing the momentum needed to advance sustainable air travel.

The pathway to decarbonizing aviation remains complex, but the need for clear, enforceable policies is undeniable. As California reconsiders its approach, there remains an opportunity to craft regulations that balance innovation, industry needs, and environmental responsibility. 

In the meantime, the broader aviation industry must continue to invest in and prioritize the development of SAFs and other low-carbon technologies. The journey to sustainable air travel is far from over, and with the right strategies and partnerships, the sector can still achieve significant progress in the years ahead.
