A pathway to a more sustainable lifestyle

So our world is in a dire state and we still don't do enough as a global community to mitigate this. Extreme weather events increase, even in our hemisphere. Interestingly, it still mostly seems to be business as usual, even though the vast majority of scientists already agree that the climate emergency is man-made. - business seems to be largely as usual. Changing behaviour isn't easy. The concept of humans being rational, independent actors primarily driven by self-interest has been challenged by advancements in behavioural science. We now understand that human behaviour is predominantly irrational, subconscious, and influenced by external circumstances. So what can we do to make the changes necessary and take everyone on this journey with us? It surely sounds like a Herculean task (and as we just come out of the pandemic we still are very aware about just how tricky unpopular state regulations sometimes are).

Design to the rescue! There is a powerful tool taken from behavioural sciences (like psychology) that can guide individuals towards an environmentally friendly lifestyle without sacrificing freedom of choice: nudging. Nudging, as a design tool, has the potential to effectively inspire behaviour change by gently steering individuals towards more sustainable choices while preserving their autonomy. Nudging contrasts with other ways to achieve compliance, such as education, legislation or even enforcement.

Nudging operates on the principle that human behaviour is influenced by subtle cues in our environment. By making small adjustments to the design of choices, nudging can lead individuals towards more environmentally friendly options. Importantly, this approach respects individual freedom, as people still retain the ability to make their own choices.

One of the key advantages of nudging is that it facilitates behaviour change without invoking a sense of loss or restriction. Traditional methods of promoting sustainability often rely on imposing regulations or removing choices altogether. However, nudging recognises that people are more likely to adopt sustainable behaviours when they feel empowered and in control of their decisions. And rightly so. By gently guiding individuals towards environmentally friendly options, nudging allows them to align their choices with their values without feeling forced.

Subtle cues can be employed in various contexts to encourage environmentally friendly behaviour. For instance, in grocery stores, placing fruits and vegetables at eye level and providing clear information on sustainable packaging nudges consumers towards healthier and more eco-friendly food choices. Or let's take a look at the Tulane University study in New Orleans, where over 80% of students ate vegan when it was offered as the default choice and meat had to be requested separately. Similarly, optimising public transportation options, such as increasing convenience and user experience or providing real-time updates, could encourage individuals to reduce their reliance on cars. These small adjustments in design create a ripple effect, leading to significant positive impacts on the environment. Imagine electric busses using empty bus lanes and always having green lights on intersections. Those busses have large doors for easy and fast access, plenty of seating and they arrive in high frequency. Charging gets done automatically and digitally for a worry free commute. At the same time private cars might have to wait on red traffic lights far more often and get charged substantial fees when parking on scarce spaces in the city. If you are on your way to work, which one will you choose?

Often we’re bad at making decisions that are good for us. Human behaviour is frequently influenced by ingrained habits (ie. think childhood) and cognitive biases (ie. rules of thumb). Nudging recognises these barriers and strategically addresses them. By leveraging psychological insights, nudging helps individuals overcome inertia, procrastination, or information overload. For example, setting default options on thermostats to energy-efficient settings or utilising smart meter feedback can prompt individuals to conserve energy without requiring conscious effort. Making complex life easier.

Nudging empowers individuals to make informed choices without compromising their freedom. By presenting information in a clear and accessible manner, such as energy consumption data or carbon footprints, nudging enables people to evaluate the environmental impact of their decisions. Without this transparency it is hard to save resources even if you wanted to do this intentionally. What if the system showed you not only how much water was used by taking a shower but a price tag, too? How about displaying the fuel consumption after a car trip and transparently illustrating it in necessary measures to offset the impact? Transparency is key. Who would run a business without looking at key performance indicators? This increased awareness empowers individuals to take responsibility for their choices, leading to a sense of ownership and satisfaction in living in tune with the planet.

To meet the urgent need for behaviour change in the context of ecological sustainability, innovative approaches that respect the autonomy of the individual are required. Nudging, as a design tool, offers a powerful option by gently guiding individuals towards environmentally friendly choices without infringing on their freedom. By leveraging subtle cues and psychological insights, nudging can inspire behaviour change, overcome barriers, and empower individuals to live more environmentally friendly lives. We need to take everyone on the journey with us!
