Last month, the Amazon founder purchased a Gulfstream G700 — a luxury jet manufactured by Gulfstream Aerospace. According to Business Insider , it is considered one of the largest and most advanced private jets in the world.

The G700 is also said to be capable of reaching a top speed of around 1,142 km/h, close to the speed of sound (around 1,235 km/h at 20 degrees Celsius and standard pressure). In addition, Jeff Bezos’ new plane also has 20 panoramic windows and “an ultra-quiet cabin with 100% fresh, plasma-ionized air, replenished every 2-3 minutes.”

The G700 was seen taking off from Ibiza last weekend, while Bezos and his fiancée, Lauren Sanchez, were also on board a superyacht near the Mediterranean island.

Public flight data also shows that the 60-year-old billionaire’s plane has made 28 flights in the past 39 days – emitting 264 tons of carbon, 17 times the average American’s emissions in a year, JetSpy reported.

In response to the report, Bezos’ representative explained that the billionaire uses sustainable aviation fuel for his trips, as well as pays for carbon offsets and funds projects that reduce air pollution.

Before the G700, Jeff Bezos also owned two aircraft models of the same brand, the Gulfstream G650 and the Pilatus PC-24. As of August 21, the Amazon founder’s net worth was valued at $203 billion by the Bloomberg Billionaires Index – making him the second richest person in the world after Tesla CEO Elon Musk .
