Sharing City Seoul — A Municipal Ordinance to Build a Sharing-Economy Ecosystem

In September 2012 Seoul's mayor declared the city a 'Sharing City' and, that December, the Seoul Metropolitan Council passed an ordinance creating a legal framework and certification process for 'sharing organisations' — businesses and non-profits offering shared cars, parking, tools, clothing, accommodation or space.

The ordinance aimed to build a legally certified, city-supported sharing-economy ecosystem, expanding access to underused public and private assets.

A Sharing Promotion Committee launched in March 2013 and a dedicated Seoul Innovation Bureau (58 staff, roughly EUR 5.5 million annual budget per EBRD's review) was set up to run the programme, opening around 800 public buildings for shared use and certifying sharing organisations, with a 50% discount on public parking for sharing operators.

Certified organisations rose from 37 in the first year (2013) to 92 by 2015, when the city announced a second-phase expansion plan. Combined car-sharing membership (SoCar, Green Car) passed 400,000, with SoCar's user base growing more than ten-fold in four years, and analysis cited by the city found a single shared car can substitute for 16.8 privately owned vehicles. A city-commissioned survey of 2,500 Seoul residents in May 2016 found nine in ten aware of at least one sharing-city project, and 82% of those who had used a service reporting satisfaction. Seoul's own second-phase business case, cited by the EBRD Green Cities programme, projected roughly 30,000 tonnes of CO2 savings and over 1,200 new jobs from expansion, though these are the city's own projections rather than independently measured outcomes.

Equity is the programme's least evidenced dimension: neither the city's own materials nor the EBRD review report any breakdown of participation or benefit by income, age or district, so it is not possible to confirm whether Seoul's sharing economy reached beyond car-owning, digitally engaged residents. The certification-and-subsidy model is a genuine and unusually well-institutionalised piece of city-scale economic experimentation, but the strongest verifiable numbers are about scale and satisfaction rather than distributional impact.
