Hong Kong's Green Push: How This City Stacks Up Against Global Sustainability Leaders

Hong Kong's sustainability efforts are intensifying, yet the city remains behind peers like Singapore and Copenhagen when it comes to renewable energy adoption and circular economy initiatives, according to recent comparative analyses of major global metros.

The government's expanded landfill diversion targets aim to reduce waste sent to three landfills—located in Tseung Kwan O, Nim Shue Wan, and Ta Lam—by 35 per cent by 2035. Currently, Hong Kong diverts roughly 32 per cent of its waste. That compares favourably with London's current 35 per cent diversion rate, but lags behind Singapore's aggressive 70 per cent target and Amsterdam's impressive 85 per cent achievement.

On renewable energy, Hong Kong remains a laggard. The city generated just 2.6 per cent of its electricity from renewable sources last year, predominantly from solar installations and a modest offshore wind project in the northeast waters. By contrast, Denmark now derives over 80 per cent of its electricity from renewables, while Singapore has deployed solar panels across public housing estates with greater intensity. Hong Kong's ambitious new target of 10 per cent renewable energy by 2033 still trails these counterparts.

Where Hong Kong excels is in electric vehicle adoption. The territory boasts over 98,000 registered EVs—roughly 7 per cent of all vehicles—outpacing many Western cities, thanks partly to generous tax breaks and a growing charging infrastructure. Central and Causeway Bay now feature charging hubs, while the government has committed to phasing out petrol vehicles entirely by 2050.

Urban greening initiatives show mixed results. The government's plan to convert underused carparks and rooftops in dense neighbourhoods like Mong Kok and Sham Shui Po into green spaces reflects global best practices seen in Toronto and Seoul. However, Hong Kong's limited land means such projects remain modest in scale. The anticipated expansion of the Central Waterfront and revitalisation of the Star Ferry terminal precinct will test the city's commitment to integrated sustainability.

Transit-oriented development presents another strength. With 99 per cent of residents living within 400 metres of public transport, Hong Kong's MTR system moves 5.7 million passengers daily, far outpacing car-dependent cities. Yet congestion pricing—successfully implemented in Singapore, London, and Stockholm—remains off the table here, despite transport experts flagging its potential to reduce emissions.

Experts suggest Hong Kong risks falling further behind without bolder policy moves. Environmental groups are calling for aggressive building retrofit programmes, tighter plastic restrictions, and concrete timelines for transitioning away from coal-fired electricity imports from mainland China—a critical vulnerability in the city's sustainability roadmap.
