“Getting behavior change to happen is not an easy thing,” says Dagny Tucker, founder¹ of Vessel². “If we look at a community that’s considered very sustainably-minded, i.e., Boulder³, Colorado, you’ll find that in a survey of local cafes, less than 10 people are bringing their own cup every day.”

Vessel 的创始人 Dagny Tucker 说：“让人们改变习惯并不是一件容易的事，即使我们说的是像博尔德这样以环保闻名的社区，调查显示也只有不到10%的人会每天自己带杯子来。”

Vessel 一开始选择在博尔德的四家咖啡厅展开这个项目，之后还准备逐步扩张。

消费者们可以通过一个APP来参与到这个免费的系统里。（如果有人没有在五天之内归还咖啡杯，他就会受到罚款。）

As they use the mugs, they’ll get reports on how much waste they’re preventing and how much they’re trimming their carbon footprint and saving water.

在他们使用咖啡杯的同时，他们会收到相关的报告来显示他们已经协助减少多少垃圾产出、降低了多少碳足迹、节约了多少水。

Tucker 最早是于2016年在纽约试运营这个系统的，她曾在那里的帕森斯设计学院任教。

“The paper cup was really the most highly visible sign of disposability I could see,” she says. “Every fifth person walking down the street [in New York] is carrying a paper cup, which they use for a matter of minutes and then throw away.”

她说：“纸杯子真的是我见过最能代表一次性使用的东西了。纽约街上每5个人就有一个拿着纸杯子，这个杯子只被他们用上几分钟，然后就被丢弃了。”

她当时在曼哈顿和布鲁克林的几个咖啡厅实验了这个项目，其间不断迭代这个系统的设计，结果发现消费者还挺喜欢这个点子的。

并且，在他们使用这种杯子的时候，他们发现这样做似乎还有更大层面上的意义。

“Our research in New York City demonstrated after a couple of weeks of using Vessel, people began to evaluate all their single-use disposable choices,” she says.

她说：“纽约市的这个Vessel实验进行几周后，人们就开始全面审视该不该用一次性杯子了。”

“We’re attempting to disrupt the status quo of an entire industry, essentially,” she says. “And we think that by giving the user immediate⁴ feedback on the positive impact they’re having by making a slight behavior change that we’re going to be able to see that turn into larger behavior changes.”

“从根本上来讲，我们是要颠覆一整个行业的现状。我们认为，通过让人们知道自己的这点小举动能带来多大的正面影响，我们能在越来越大的范围里引发这种习惯转变。”

随着整个系统的扩展，随着回收凉亭被设立在更多诸如车站一类的地方，这种咖啡杯会变得越来越容易使用。

同时，对于咖啡厅一方来说，杯子的设计初衷也是让他们尽可能用着方便。

“I wanted an intervention⁵ that was a win for everyone,” says Dagny.

Dagny说：“我希望这个干预措施对每个人都有利。”
