OneWeb

OneWeb's 2022-2023 sustainability filings with the UK CAA and FCC committed the LEO satellite operator to a 5-year post-mission deorbit standard, substantially more aggressive than the 25-year industry norm. The commitment was credited by orbital-debris researchers and the European Space Agency as a positive industry precedent for sustainable mega-constellation operations, though OneWeb's overall ~648-satellite constellation remains a fraction of Starlink's planned scale.

OneWeb has established industry-leading orbital sustainability practices through its 'Responsible Space' initiative. The company designed its 648-satellite constellation with built-in debris mitigation: all satellites include propulsion for active deorbiting at end of life, orbit at lower altitudes (1,200km) than Starlink for faster natural decay, and maintain collision avoidance protocols. OneWeb has committed to zero long-lived debris and publishes orbital data for transparency.
