We often think going paperless is eco-friendly—but is our digital life as green as we believe? Every email, file, and cloud service relies on data centers, and together they produce significant carbon emissions. This hidden impact is called digital pollution. In this episode of Climate Watch, Fei Fei explores how our everyday online habits affect the environment and speaks with Ian Chew, founder of Greenie Web, a Singapore-based startup working to clean up the digital world.

China has released its first central government roadmap for the national carbon market, marking a turning point in the country’s climate policy. The plan sets out milestones to expand coverage across major emitting industries by 2027 and build a fully functional cap-and-trade system by 2030. In this episode, Fei Fei sits down with carbon market analyst Qin Yan to unpack what these targets mean in practice. We explore how China can boost the vitality of its carbon market, what challenges industries may face, and how the system could align with global carbon trading under the Paris Agreement.

In Quanzhou, oysters are more than food — they’re part of the local history. For centuries, oyster shells have been used to reinforce bridges, build storm-proof homes, and shape coastal life. This episode explores how 11th-century engineers employed oysters in the construction of the Luoyang Bridge, with insights from historians. We also hear from Professor Cai Lizhe of Xiamen University and Lin Jianyi from the Chinese Academy of Sciences on how oyster shells are used today to restore soils, filter water, and even cut carbon. From ancient ingenuity to modern climate action, discover how the humble oyster has sustained people and places.
