But despite all these changes, it's important to remember that these policies are less of a choice and more of an imperative.
Shenzhen has to forge a sustainable future because the surrounding environment has been tarred by years of hazardous development which has polluted rivers, dirtied the air, and degraded land resources.
And Shenzhen has big ambitions because it is going to be right in the middle of the anticipated Greater Bay Area - a mega region comprising 69 million people - and that means creating a sustainable future for its citizens.
What's true for Shenzhen is also true for China more generally. The challenges are the same, but the price of failure through climate deterioration, widespread pollution, impacts on public health and possibly social stability are too great.
But as China adapts to and confronts these sustainability challenges, we'll see innovative ideas emerge, new sectors grow, and sustainable solutions present themselves, and that's why we believe that Shenzhen and China will be a key space to watch and a likely source of innovative and investible ideas in the sustainable investing field in the future.
