MaCoS: When Sustainability Becomes a Shared Journey

There are courses you attend. And there are journeys you experience.

Management and Communication of Sustainability, known as MaCoS, within the PhD programme Innovative Engineering Technologies for Industrial Sustainability at the Department of Industrial Engineering of the University of Salerno, was not simply a series of lectures. It was a shared path.

On the first morning, something important happened. We did not just open a course. We formed a team. A group of PhD students and professors who agreed, almost instinctively, that sustainability cannot be studied in isolation. It must be discussed, questioned, and sometimes even challenged.

From the very beginning, the atmosphere was based on dialogue. Not because dialogue is fashionable, but because it is necessary. Sustainability today is too complex to be reduced to slides and formulas. It requires listening. It requires different perspectives. It requires patience.

One of the core ideas of MaCoS was simple and, in some ways, uncomfortable. Technical solutions are not enough.

Engineers are trained to solve problems. We rely on numbers, models, standards and calculations. Yet sustainability goes beyond efficiency improvements and technological optimisation. During the course we explored the environmental system as a dynamic and interconnected whole. We revisited the Sustainable Development Goals, especially those related to cities, responsible consumption and climate action. We analysed pollution, environmental impacts and treatment systems.

Then we moved into Life Cycle Thinking. Looking at a product or a system from raw material extraction to end of life changes your perspective. It forces you to slow down. It forces you to ask where impacts truly occur. It forces you to recognise that solving one problem may simply shift it somewhere else.

Through Life Cycle Assessment, Life Cycle Costing and Social LCA, students worked on real case studies, comparing packaging systems and analysing environmental performance. What people assume to be sustainable is not always supported by evidence. And what evidence shows is often more nuanced than expected.

A key lesson emerged naturally. You cannot manage sustainability without measuring it. And you cannot communicate sustainability without credibility.

We also reflected deeply on the meaning of management. Not in a bureaucratic sense, but in a human one.

To manage means to take care.

An Environmental Management System is not a machine. It is a structured way of identifying impacts, setting objectives, monitoring performance and improving over time. It is discipline. It is responsibility. It is the decision to move from good intentions to organised action.

Throughout the course, the PDCA cycle accompanied us. Plan, Do, Check, Act. It may sound technical, but it is profoundly human. It reminds us that improvement is iterative. That mistakes are part of learning. That checking our own work requires humility. That acting means having the courage to change.

At the end of the course, students were reminded that learning from mistakes is the best way to grow and to react constructively to challenges. This applies to research. It applies to organisations. It applies to life.

Perhaps the most powerful reflection concerned communication.

Communication is not decoration. It is not the final step added to a completed project. It is the bridge between knowledge and society.

We discussed ISO 14001 and EMAS. We analysed sustainability reporting, verification processes and greenhouse gas inventories. We examined how data become information and how information becomes accountability. But beyond standards and regulations, one idea stayed with us. Communication is connection, not perfection.

We do not communicate sustainability to appear flawless. We communicate to build trust. Reporting without management is empty. Management without communication is invisible.

One of the most meaningful moments of MaCoS was when each PhD student presented their research. Ten minutes to present. Ten minutes to discuss. Even a single slide was enough.

It was not an evaluation. It was an invitation to reflect.

Students were asked to present their research staying in the middle. Between scientific depth and social relevance. Between technical accuracy and accessible language. Between data and decisions.

For many, this was the most challenging exercise of the entire course. Explaining your research to peers from different engineering fields forces you to rethink what truly matters. It forces clarity. It forces humility.

At the beginning of the course, students created a word cloud to describe what sustainability meant to them. At the end, we updated it. Words such as empathy, generations, impact, connection and humility appeared more clearly. That transformation was perhaps the most meaningful result of all.

When the course concluded, a simple message was shared. Remember the PDCA cycle. Learn from mistakes. Look at problems from more than one point of view. Keep an open mind. And most importantly, enjoy every single second of your life.

Because sustainability is not only about systems, standards and indicators. It is about people. It is about responsibility across generations. It is about caring for something larger than ourselves.

MaCoS has ended for this academic year. But the journey continues.
