Study: Green nudges reduce plastic waste from food deliveries in China

A new study shows that simple "green nudges" can significantly reduce plastic waste from food delivery services in China. The research, published in Science last week, found that tweaking default options and rewarding sustainable choices led to a major drop in demand for disposable plastic cutlery. 

According to the study published in Science, making "no cutlery" the default option and giving customers points if they chose to forgo utensils increased orders without cutlery by 648%. The authors estimate that if applied nationwide, these small nudges could reduce use of plastic cutlery by over 20 billion sets and prevent millions of metric tons of plastic waste annually.

Albert Park, chief economist of Asian Development Bank and co-author of the research joins CGTN's Guan Xin to talk more about the research and its broader implications.
