George J. Priester Aviation announces partnership with 4Air to support sustainability in aviation

October 14, 2025:

George J. Priester Aviation has announced that it has partnered with 4Air, the global leader in business aviation sustainability, in order to reduce aircraft emissions associated with climate change. George J. Priester Aviation's clients may now opt-in on their own to participate in the programme, personally doing their part to protect the climate.

“At George J. Priester Aviation, we believe that leadership in aviation means not only providing exceptional service, but also being responsible stewards of our environment,” said Madison Priester, director of marketing and sustainability. “Partnering with 4Air allows us to give our clients meaningful options to offset and reduce their emissions today, while we work toward a more sustainable future for private aviation through the advancement of sustainable aviation fuel.”

George J. Priester Aviation's clients can opt-in to reduce their carbon footprint generated from flight activity, beginning with the use of verified carbon offsets, with the option to support sustainable aviation fuel (SAF) coming in the near future. Each carbon offset corresponds to a verified reduction or avoidance of one metric ton of carbon dioxide, supported by projects that meet strict criteria and standards. As the most viable near-term solution to reduction emissions in aviation, SAF reduces the lifecycle carbon footprint of aviation fuel by up to 80% compared to traditional jet fuel, offering a significant reduction in the sector's direct emissions. 4Air's sustainability programmes specifically tailored to business aviation allow users to support science-based, independently verified emissions reduction projects across the globe.
The partnership with 4Air extends across George J. Priester Aviation's full range of services, including aircraft management, charter and jet card programmes. This means that every client, whether they own, operate or charter aircraft through the Priester family of companies, which includes Priester Aviation, Mayo Aviation, Hill Private Aviation and the recently acquired Omni Air Transport, can take part in meaningful sustainability initiatives. Participants can choose to offset the carbon impact of their flights or contribute to the advancement of SAF production, ensuring that responsible environmental stewardship is available to every type of private aviation user.

“Our collaboration with George J. Priester Aviation reflects a growing commitment among operators to lead on sustaining aviation,” said Nancy Bsales, chief operating officer of 4Air. “By offering carbon offset options, George J. Priester Aviation is making it simple for aircraft owners to participate in meaningful climate action.”
