It wasn’t a landmark that changed how I think about sustainability—it was a bike lane.
In Valencia, they are everywhere. Not hidden or symbolic, but fully integrated into the city, running alongside roads, through green spaces, and into daily life. At first, I used them simply because they were convenient. With the help of Valenbisi (www.valenbisi.es), cycling became part of my routine—not a conscious “sustainable choice,” but the easiest option available.
That is when my perspective shifted.
One afternoon, cycling through the dried riverbed of the Turia Gardens toward the City of Arts and Sciences, I realised how deliberately sustainability had been built into the city. What was once a river is now a continuous green corridor—used not just for leisure, but for movement, connection, and everyday life. The journey felt effortless, but it was not accidental.
Sustainability is often framed as an individual responsibility: bring a reusable bottle, avoid plastic, make better choices. But living here has shown me that the most impactful choices are often shaped long before the individual makes them. They are designed into the system.
This became even clearer when I travelled by train to Madrid and Barcelona, reducing my carbon footprint in line with United Nations Sustainable Development Goal 13: Climate Action. In areas of high tourism, the strain on infrastructure, waste systems, and public space becomes more visible—raising questions linked to SDG 11: Sustainable Cities and Communities.
Returning to Valencia, the contrast was not just environmental, but structural.
The city’s abundance of green spaces—parks woven into urban life rather than set apart from it—actively supports environmental goals such as improving air quality and reducing urban heat. These are not just amenities; they are examples of sustainability in practice.
As a law student, this has reshaped how I understand sustainability. It is not only about encouraging better behaviour, but about creating legal and policy frameworks that make sustainable choices accessible, normal, and even unavoidable. Bike lanes, public transport systems, and protected green spaces are not accidental—they are the result of planning, regulation, and long-term commitment.
Alongside these structural insights, I have also taken practical steps to reduce my impact. I use Too Good To Go (www.toogoodtogo.com) to minimise food waste, supporting SDG 12: Responsible Consumption and Production. I rely on Closca (www.closca.com/pages/app) to avoid single-use plastics, and Google Maps (www.google.com/maps) to prioritise walking and public transport. Even small digital choices, such as using Ecosia (www.ecosia.org), allow me to contribute to environmental efforts beyond my immediate surroundings.
What studying abroad has taught me is that sustainability is most effective when it is built into the fabric of everyday life.
The bike lane did not force me to make a better choice—it made the better choice obvious.
And that is what I will carry forward: not just the intention to live sustainably, but the understanding that lasting change comes from systems that make sustainability the default, not the exception.
