But what does sustainability really mean?
It is the ability to carry out human activities without compromising—or by minimising their impact on—the natural balance and the resources that future generations will depend on.
In other words, it means living and producing today without consuming tomorrow.
It is not simply an environmental principle, but acultural mindset:the awareness that every action, every personal or professional choice, leaves its mark over time.
The Pillars of Sustainability
Sustainability is built upon three closely interconnected dimensions:
- Environmental– protecting and regenerating natural resources, preserving biodiversity, and reducing emissions and waste.
- Economic– balancing efficiency with respect for natural capital, avoiding production at the expense of the future.
- Social– ensuring quality of work, health, human relationships, strong local communities and transparency throughout production processes.
None of these pillars can stand on its own.
True sustainability issystemic: a dynamic balance between what we take and what we give back.
How Environmental Sustainability Is Measured
Measuring does not mean reducing everything to numbers; it means understanding where action is needed.
Internationally recognised tools help quantify the environmental impact of a product or activity.
The main ones are:
- Carbon Footprint→ measures the amount of carbon dioxide equivalent (CO₂e) emitted by an activity, a product or an organisation.
It is the most widely used indicator for comparing the climate impact of different sectors and production systems. - Water Footprint→ measures how much water is used, directly and indirectly, and in what geographical context.
Not all water has the same value: using one litre where water is abundant does not have the same impact as using it in an arid region. - Life Cycle Assessment (LCA)→ evaluates the overall environmental impact of a product throughout its entire life cycle, from production to disposal, including materials, energy, transport and waste.
- Biodiversity, Soil and Air Indicators→ assess the health of natural ecosystems and measure the effectiveness of environmental protection practices.
From Numbers to Awareness
Among these, the most widely used tool is theCarbon Footprint,which calculates all greenhouse gas emissions expressed as carbon dioxide equivalent (CO₂e).
Using this approach, it is possible, for example, to estimate the CO₂ emissions generated by the production of a single bottle of wine, one litre of olive oil or a car journey.
The aim, however, is not merely technical; it iscultural.
Learning to measure means learning to make choices and to take responsibility for our actions.
The challenge, then, is not to produce less, but toproduce better, with respect for the land and for those who cultivate it. Sustainability is not about reduction; it is aquality of life.
