Working on the goal of carbon neutrality as a shared community project, one that sees the Hong Kong government truly engaging with voices from all parts of society, could be a powerful way of rebuilding trust in a divided city.

The city, with its enviable budget surpluses, has the resources to clean up its environment and lead the circular economy. A waste charging scheme has been announced, and ‘reverse vending machines’ are being considered.

Rising sea levels, pollution and extreme weather are global problems that must be jointly tackled by the best minds in both the US and China. The hi-tech clusters in Silicon Valley and the Greater Bay Area must lead the way.
