What we learned measuring the carbon footprint of Festival Estéreo Picnic

Picturing the carbon footprint of a music festival is not simple. It is not just about the energy used on stage or the waste generated. Behind each edition there are thousands of invisible emissions: international flights, supply chains, logistics, catering and mass travel.

Since 2023, CarbonBox has supported Páramo in measuring the emissions impact of Festival Estéreo Picnic (FEP). Not as a requirement, but as an ongoing process that, with each edition, gains in precision, depth and honesty.

Measuring an event means measuring its entire life cycle

Estimating the carbon footprint of a festival means quantifying, with verifiable methodologies, all sources of greenhouse gas (GHG) emissions associated with its operation.

This includes far more than the days of the event: months of planning, coordination travel, setup, on-site operation and teardown. It also covers energy consumption, the transport of artists and attendees, catering, the materials used and waste management.

In essence, it is a complete impact inventory. And like any well-made inventory, its value lies not only in the final result, but in what it allows us to understand.

Learning to measure the unseen and the responsibility of being Carbon Neutral

The first measurement was, above all, an exercise in methodological design. Festivals present challenges that are rarely covered in traditional manuals: collecting data from hundreds of suppliers, estimating the travel of tens of thousands of attendees, or accessing information about artists’ international flights.

The solution has been to combine technical tools with fieldwork: real-time surveys, training processes, contractual adjustments and close collaboration with Páramo’s teams. This process has also shown that events can evolve toward more sustainable models when decisions are based on data. As we explore in Low-carbon events are possible: Festival Estéreo Picnic, this has been a real case of how measurement makes it possible to identify concrete opportunities for reduction and improvement.

Events like Festival Cordillera served as a laboratory. FEP, given its scale and complexity, became the greatest challenge: multiple days, global artists, high international attendance and a large-scale logistics operation. Measuring in this context is never perfect. But it can be rigorous, transparent and consistent.

One of those results was, for the second consecutive year, achieving the festival’s carbon neutrality certified by ICONTEC. A milestone that did not arrive as a result of a single action, but as the outcome of a demanding, iterative and deeply rigorous technical process. Behind that certification there are audited data, difficult decisions, constant work to improve the quality of information and, above all, a great deal of learning.

The data point that redefines the conversation

There is a key moment in every measurement: when the results reveal where the impact really lies. In FEP’s case, close to 90% of emissions come from the air travel of attendees and artists. Not from the event’s energy, nor from waste, nor from on-site operation.

This finding completely changes the conversation. The greatest impact occurs before the festival even begins: in the flights connecting cities and continents.

More than a criticism, it is a clear signal of where to focus efforts: mobility, programming decisions, public communication and incentives for lower-impact alternatives.

From data to decisions

Measuring is only the first step. The real value lies in using that information to improve. Over these three years, the results have allowed Páramo to make more informed decisions: optimizing logistics, prioritizing local suppliers, strengthening waste management and exploring cleaner energy sources.

They have also opened the door to more structural discussions, such as understanding the public’s travel patterns and designing sustainable mobility strategies. Not all emissions can be eliminated. But measuring makes it possible to distinguish between symbolic actions and changes that truly reduce impact. There are concrete practices that can be implemented from planning through to operation. In Revolutionize your events: best practices for sustainable concerts and conferences, we detail key actions that make it possible to reduce emissions effectively at large-scale events.

Measuring is not enough, but without measurement there is no starting point. Each edition of the festival generates information that did not exist before. That information makes it possible to identify real reduction opportunities and make decisions based on evidence, not intuition.

Every improvement implemented, however small, represents emissions that do not reach the atmosphere. And, accumulated over time, those decisions do make a difference.

The journey continues

Three editions, three complete inventories and an increasingly robust process. In a context where sustainability often remains merely rhetoric, measuring with rigor and acting accordingly remains a sign of leadership.

CarbonBox will continue to support this process, with better data, greater analytical depth and a clear conviction: sustainability starts with understanding, precisely, the real impact.

Festival Estéreo Picnic will sound again. And with it, measurement will return. Because only what is measured can be improved.
