How green nudges can contribute saving the planet
Adopting a responsible attitude, both individually and collectively, is not easy: although most of us have good intentions (64% of people in 50 countries believe that climate change is a global emergency), we don't necessarily take action.
So why don't we act ? The truth is that human beings are not rational who always act in their best interests. A new discipline, behavioural economics, has demonstrated that our decisions are more influenced by the context, our emotions and the judgment of others than by our rational mind.
The Nudge approach lies on this observation. A Nudge is a cheap and easy-to-implement lever to encourage people to tend to a certain behavior, without interfering with their free will. Nudge doesn’t impose rules, punish or make you feel guilty but it encourages you to take better decisions!
The most famous example of nudge : The fly in men’s toilet
Amsterdam Airport Schiphol, one of Europe's busiest air hubs, carved flies into the urinals of its men's toilets in the 1990s. This 'target' instinctively influenced men to adjust their aim, reducing significantly splashing. It was appreciated by both users and the airport cleaning management, which maintenance costs decreased by 80%!
What about using the nudge approach to encourage people to adopt more environmentally friendly behaviour ? Many inspiring examples of green nudges exist.
