Gulfstream re-earns NBAA environmental accreditation, first OEM to hold all four categories

Gulfstream has re-earned the NBAA Sustainable Flight Department Accreditation, becoming the first original equipment manufacturer to hold accreditation in all four program categories and the first OEM to earn reaccreditation.

According to Private Jet Card Comparisons, Gulfstream achieved credit in all four sustainability categories: flight, ground support, infrastructure, and operational activities. Of the 25 accredited program members, only four others—all corporate flight departments—hold accreditation in all categories.

Environmental milestones since 2019

Gulfstream reported several improvements compared to its 2019 baseline. The manufacturer achieved a 44% reduction in fuel consumption and flight emissions across its Flight Department fleet.

Ground support emissions fell 18% through the use of electric tugs, electric golf carts, and EV charging infrastructure. The company also reported a 25% reduction in emissions intensity per square foot and more than 2.3 million square feet of LEED and BREEAM certified facilities.

Employee air travel emissions dropped 43%, with a 55% improvement in emissions per employee. In 2025, Gulfstream reported a 21% improvement in emissions per flight hour and nearly 719.8 metric tons of carbon dioxide emissions improvement through sustainable aviation fuel utilisation.

Mark Burns, Gulfstream president, said that "sustainability is not a standalone initiative—it is integrated into how we operate, innovate and lead." Burns added that the reaccreditation "reflects the dedication of teams across our company who are driving meaningful progress, embracing continuous improvement and helping position Gulfstream and business aviation for a more sustainable future."

The accreditation program

The NBAA Sustainable Flight Department Accreditation Program recognizes aviation organisations for environmental and sustainable operations. Industry certifier 4AIR manages the program through a partnership with NBAA announced in March.

Nancy Bsales, 4AIR chief operating officer, said that "Gulfstream continues to lead by example, showing that real sustainability leadership is built on measurable data, accountability, and continuous improvement across every part of an operation."

The reporting does not say whether Gulfstream's reaccreditation affects pricing or terms for customers, or whether it influences purchasing decisions among operators.
