Frequently Asked Questions
How many private jets flew to UN General Assembly 2025 2025?
Carbon Sky Index tracked 2,978 private jet movements across Teterboro, White Plains, Farmingdale, New York, and Newark during the UN General Assembly 2025 2025 window (September 21, 2025 to September 27, 2025). These 1,621 distinct aircraft emitted an estimated 20,012 metric tonnes of CO₂.
How much CO₂ did private jets emit at UN General Assembly 2025 2025?
Private jets flying to and from UN General Assembly 2025 2025 emitted an estimated 20,012 metric tonnes of CO₂ in total. Carbon Sky Index calculates emissions using the EUROCONTROL EMEP/EEA Guidebook 2023 methodology, covering both LTO (landing and takeoff) and cruise phase emissions.
Which airport had the most private jet traffic during UN General Assembly 2025 2025?
Carbon Sky Index monitored traffic across Teterboro, White Plains, Farmingdale, New York, and Newark. The highest volume of arriving aircraft came from Washington, with 74 inbound flights recorded.
How does Carbon Sky Index track private jet emissions?
Carbon Sky Index uses ADS-B transponder data to identify private jet movements at monitored airports. CO₂ estimates are calculated per flight using the EUROCONTROL EMEP/EEA Guidebook 2023 methodology, which accounts for aircraft type, route distance, and both LTO and cruise phase fuel burn. Data is updated daily.
Flight data is sourced from ADS-B transponder signals aggregated from a global receiver network and updated daily. CO₂ estimates are calculated using aircraft-type hourly burn rates from the Carbon Sky Index emissions model. Read methodology →
