Since becoming the launch customer for Signature's Renew SAF program at San Francisco International Airport in 2020, NetJets has continued to invest in increasing SAF availability across U.S. airports with a commitment to purchasing up to three million gallons.
Despite its benefits, SAF is not entirely carbon-neutral due to emissions generated during feedstock cultivation, processing, and transportation phases. Additionally, it still produces non-CO2 emissions like nitrogen oxides that can harm agricultural crops.
The challenge of sustainably sourcing feedstocks also limits SAF's potential as a long-term solution for achieving net-zero emissions by 2050. Limited supply could lead to competition with food production and unsustainable land use if scaled up significantly.
While flying remains one of the most carbon-intensive activities globally, SAF offers a short-term solution for reducing CO2 emissions. The International Air Transport Association estimates that using SAF could contribute around 65% toward reducing these emissions.
However, reaching net-zero CO2 emissions by mid-century will require multiple strategies beyond just increased reliance on SAF. New technologies such as electric and hydrogen-powered aircraft are needed alongside carbon offsets or capture initiatives—and ultimately—a reduction in overall flying activity may be necessary.
Private aviation continues growing post-pandemic despite its role generating significant carbon emissions within this sector; studies show private jets contributed approximately 15.6 million tons directly into our atmosphere last year alone—with numbers rising steadily since pre-pandemic times due largely thanks both affordability increases coupled pandemic-related factors driving demand upwards especially here United States where majority registered today according recent research findings published Nature journal
