Airport chief executive Robert Sinclair said the proposal was a "long-term vision for London City Airport, detailing how London's most central airport can meet continued demand sustainably, create jobs and opportunities for east London, and support the capital as a major global city for tourism and business". "These proposals reflect the airport's changing role, with an increasing proportion of leisure passengers choosing the airport, and east London's continued transformation." John Stewart, chair of Hacan East which campaigns about the impact of the airport on local communities, said: "For all its green talk, this plan would be a disaster for residents. "Flight numbers could almost double from today's total." The airport insists it will retain its eight-hour night-time closure and not permit any noisier aircraft than those currently operating. The consultation will run for 12 weeks. Newham Council, which would decide on any bid to increase operational caps, said it remained "committed to improving air quality in Newham" and pledged to make the borough "carbon neutral by 2030 and carbon zero by 2050"
