Gulfstream Secures NBAA Sustainability Reaccreditation After Cutting Flight Department Emissions

Business jet manufacturer reports progress in fuel use, ground operations and facilities against a 2019 baseline as 4AIR oversees the industry accreditation programme

KEY TAKEAWAYS

• Gulfstream says it is the first aircraft OEM reaccredited in all four NBAA Sustainable Flight Department categories.
• The manufacturer reports a 44% reduction in fleet fuel consumption and flight emissions versus its 2019 baseline.
• Gulfstream attributes nearly 719.8 metric tons of carbon dioxide emissions improvement in 2025 to SAF use.
• The assessment includes ground equipment, infrastructure and operations; 4AIR now manages the NBAA programme.

Gulfstream Aerospace has become the first aircraft original equipment manufacturer to secure reaccreditation across all four categories of the National Business Aviation Association (NBAA) Sustainable Flight Department Accreditation Program, highlighting how the business aviation sector is attempting to measure environmental progress beyond aircraft performance alone.

Announced in Savannah on October 19, 2026, the decision renews Gulfstream’s recognition in flight, ground support, operations and infrastructure. The manufacturer was also the first OEM to hold accreditation in all four categories. The latest assessment covers a range of activities, from flight department fuel consumption to building efficiency and staff travel, according to Gulfstream’s announcement.

Flight operations and sustainable aviation fuel

Gulfstream reported that its flight department fleet had reduced both fuel consumption and flight emissions by 44% compared with a 2019 baseline. Over the same comparison period, it recorded a 21% improvement in emissions per flight hour. These are company-reported operational figures rather than a claim about the emissions performance of every Gulfstream aircraft in service.

The manufacturer additionally attributed an improvement of nearly 719.8 metric tons of carbon dioxide emissions to its use of sustainable aviation fuel (SAF) during 2025. The figure relates to the company’s stated SAF activity, not to a reduction of the same amount across the entire business aviation industry.

“At Gulfstream, sustainability is not a standalone initiative—it is integrated into how we operate, innovate and lead,” said Mark Burns, president of Gulfstream, linking the reaccreditation to the company’s continuing operational improvement efforts.

Ground equipment, buildings and business travel

The company’s environmental measures extend to equipment used around aircraft and to its facilities. Gulfstream reported an 18% reduction in ground support emissions, citing electric aircraft tugs, electric golf carts and expanded electric-vehicle charging facilities. It also reported a 25% reduction in emissions intensity per square foot and said more than 2.3 million square feet of its facilities carry LEED or BREEAM certification.

Employee air travel emissions fell by a reported 43%, while emissions per employee improved by 55%, according to the same set of disclosures. These indicators provide a broader view of the company’s operational footprint, although their comparison periods and measurement boundaries matter when interpreting the percentages.

Independent review and the industry’s wider targets

The NBAA programme is designed to assess sustainability practices in four distinct areas: flight, operations, ground support and infrastructure. Its reaccreditation framework involves updated documentation and an audit, with accreditation valid for three years.

4AIR now manages the programme under a partnership announced with NBAA in March 2026, providing technical oversight, data validation and sustainability expertise. Nancy Bsales, 4AIR’s chief operating officer, described the result as an example of making improvements across flight, ground support and facilities. Dan Hubbard, NBAA interim chief operating officer, likewise pointed to fuel, efficiency and operational practices as elements of business aviation’s sustainability work.

The reaccreditation is relevant to corporate aircraft operators and their customers because it examines multiple aspects of a flight department’s environmental performance rather than relying on a single fleet metric. It does not, by itself, mean that Gulfstream aircraft or flights are emission-free. Further information on the manufacturer’s initiatives is available through Gulfstream’s sustainability overview.
