Climate Solutions' Sustainable Advanced Fuels program is an outgrowth of Sustainable Aviation Fuels Northwest (SAFN), a process created by The Boeing Company, Alaska Airlines, Portland International Airport, Seattle-Tacoma International Airport, Spokane International Airport, Washington State University, and Climate Solutions to  develop sustainable and economically viable aviation biofuels in the Northwest.

Working with a diverse group of 40+ stakeholders to establish the key sustainability criteria to drive the development of aviation biofuels, the SAFN process resulted in a report, Sustainable Aviation Fuels Northwest (SAFN): Powering the Next Generation of Flight, published on May 25, 2011 that has guided subsequent policy discussions at state and federal levels.

The SAFN initiative consisted of biofuel producers, nonprofit advocacy organizations, research institutions, government agencies, agricultural producers and other entities representing the biofuel supply chain.

Climate Solutions facilitated the stakeholder-led initiative, coordinated five workshops, and took the lead in researching and writing the final report. Due to the stakeholders' diverse goals, expertise, and experience, Climate Solutions' role required bridging divides and outlining a comprehensive 'flight path' (roadmap) that the stakeholders could agree to.

As the first regional assessment of its kind in the United States, the report examines the feasibility, challenges, and opportunities for creating a commercially viable, sustainable aviation biofuels industry in the Northwest. It assessed the feedstock pathways in the four-state Northwest area (WA, OR, MT, and ID) as possible sources for producing sustainable jet fuel and evaluated the cost, timescale, water and land usage, refining, transport infrastructure, and actual use by airlines. The feedstocks examined in the report were agriculturally based oilseeds like camelina, forest residues, algae, municipal solid waste, and others.
