Amy Skoczlas Cole, Director of eBay's Green Team, talks about her group's work and discusses how in most cases, "The greenest product is the one that already exists." This is an inherent advantage of eBay's business in enabling secondary commerce and extending products' usable lives. She shares three key lessons they've learned so far in their product marketing and customer engagement experience: Smartly combining vintage products can be considered "trading up"; Cool and stylish is much more attractive than "green"; and the importance of not being a conversation hog in dialogue (hint: be a conversational host or facilitator).
