Living green: Tiny choices that shape a city

China's Green Code: Rewriting the Rules of Growth is a four-part special series exploring how China is reshaping the way it produces energy, builds industries, grows food and lives day to day. In this episode, we travel to Shenzhen, a city known for its low-carbon ambitions, to see how sustainable living is becoming part of everyday life. Following a local resident’s journey across the city, we explore waste-sorting systems in action (1:35), a leading second-hand trading platform attracting thousands of daily visitors (9:00), a fully electrified bus and taxi network (12:55), and a net-zero building that uses significantly less energy than conventional designs (18:30). Together, these stories show how urban life is being quietly reshaped—one low-carbon choice at a time.
