Priester partners with 4Air to advance sustainability

October 20, 2025

Clients can now opt in to mitigate carbon emissions through verified offsets and support for sustainable aviation fuel, across the company’s aircraft management, charter and jet card services.

George J. Priester Aviation has partnered with 4Air in a bid to mitigate aircraft emissions associated with climate change. Clients may now opt in individually to participate in the programme, taking personal action to protect the climate.

“We believe that leadership in aviation means not only providing exceptional service, but also being responsible stewards of our environment,” says 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.”

Clients can begin by reducing their carbon footprint with verified carbon offsets, each representing a verified reduction or avoidance of one metric ton of carbon dioxide, supported by projects that meet strict standards. Support for SAF, which reduces the lifecycle carbon footprint of aviation fuel by up to 80 per cent compared with traditional jet fuel, will be available in the near future.

The partnership spans George J. Priester Aviation’s full range of services, including aircraft management, charter and jet card programmes. Every client, whether they own, operate or charter aircraft through the Priester family of companies – including Priester Aviation, Mayo Aviation, Hill Private Aviation and the recently acquired Omni Air Transport – can participate in sustainability initiatives. Participants can choose to offset the carbon impact of their flights or contribute to the advancement of SAF production, making responsible environmental stewardship accessible to all private aviation users.

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