The Hidden Carbon Footprint Behind Every Celebration
Outdoor events—whether food festivals, concerts, open-air markets, or sporting gatherings—are woven into the social and cultural fabric of the Romania-Hungary (ROHU) cross-border region. From lively city festivals to cherished rural fairs, these events unite communities, preserve traditions, and boost local economies. Yet, behind the music, laughter, and celebration, there’s an environmental cost that often goes unnoticed: the significant energy required to power every stage, food stall, and spotlight.
Many large events rely on portable diesel generators or grid electricity, both of which contribute to greenhouse gas emissions. For context, a major regional festival can consume tens of thousands of kilowatt-hours over just a few days. For example, one popular four-day festival recently used about 25,000 kWh of electricity, resulting in approximately 6,075 kg of CO₂ emissions—a figure comparable to the annual carbon footprint of a typical car in the EU (driven 4,000 km per month, according to the European Environment Agency). While these emissions are largely invisible to attendees, their environmental impact is real and significant.
Whether it’s the Kolbászfesztivál in Békéscsaba, the Arad Open Air Festival, or the Satu Mare Wine Festival, events of all types and sizes face the same underlying challenge: how to balance the joy of community celebration with the responsibility to minimize environmental impact. Fortunately, with modern energy solutions and more sustainable practices, there are now ways to dramatically reduce the carbon footprint of our region’s most treasured gatherings—without sacrificing any of the fun.
The Grid Connection Reality
Most festivals and outdoor events in the ROHU region are connected to the electrical grid—a significant advantage over remote locations that rely on diesel generators. However, grid electricity in both Romania and Hungary still carries a substantial carbon footprint that event organizers rarely consider.
Romania's electrical grid produces an average of 232 g CO₂eq/kWh, while Hungary's cleaner energy mix generates 194 g CO₂eq/kWh. While Hungary's lower emissions reflect its substantial nuclear power capacity (46.5% of total generation), both countries still depend on fossil fuels for significant portions of their electricity. Coal represents 8.1% of Hungary's energy mix, with natural gas and other sources making up the remainder alongside renewables at 24%.
For remote outdoor events—such as mountain festivals near Oradea, vineyard celebrations in the Arad countryside, or traditional fairs in rural areas around Satu Mare—the situation is far more challenging. These locations often lack grid connections entirely, forcing organizers to rely on diesel generators that emit approximately 1.22 to 1.94 kg CO₂/kWh—dramatically higher than grid electricity from either Romania or Hungary.
The Pollution Beyond Carbon: Grid vs. Generator Impact
While grid electricity in the ROHU region is cleaner than diesel generators, both sources carry environmental costs that extend beyond CO₂:
Grid electricity impacts include emissions from fossil fuel power plants (primarily coal and natural gas), which release nitrogen oxides, sulfur compounds, and particulate matter—though these pollutants are typically generated at centralized facilities away from event locations.
Diesel generators, still necessary for remote outdoor events, create direct local pollution that affects festival-goers and nearby communities:
- Nitrogen oxides (NOₓ) that contribute to smog and respiratory problems
- Particulate matter (PM2.5 and PM10) linked to cardiovascular disease
- Unburned hydrocarbons creating ground-level ozone
- Noise pollution that can disrupt local communities
The World Health Organization has identified air pollution as one of the greatest environmental health risks, making the local impact of diesel generators at remote events a particular concern for public health.
The Standards Gap: Where Guidelines Fall Short
The environmental impact of events is well-recognized, and there are international sustainability standards such as ISO 20121 ("Event sustainability management systems—Requirements with guidance for use") that provide a framework for reducing negative impacts. However, these standards often focus on broader issues like waste management, sourcing, and stakeholder engagement, while specific, actionable guidelines on energy consumption and alternative power sources are notably lacking.
The Kolbászfesztivál's 2022 energy consumption of 25,000 kWh over four days illustrates this gap perfectly. While organizers may excel at waste separation and sustainable sourcing of ingredients, the massive carbon footprint from electricity generation—6,075 kg of CO₂ emissions—receives little attention in existing sustainability frameworks. Even smaller events consuming 200 kWh per day, generating around 300 kg of CO₂, operate without clear benchmarks for sustainable energy use.
As a result, most event organizers in the ROHU region are left without clear guidance for their largest source of emissions—electricity generation.

Emerging technologies and new business models are offering event organizers more sustainable choices. Mobile battery storage units—charged with renewable energy from the grid or on-site solar panels—are becoming increasingly viable for medium and large events. Cities like Békéscsaba are now piloting mobile LiFePO₄ battery solutions to provide (nearly) zero-emission power for festivals and markets, reducing both direct emissions and noise. These batteries can be recharged during periods of renewable energy oversupply, providing a genuine circular benefit.
Other more or less promising solutions include:
- Temporary solar installations: Quick-deploy PV modules can supplement power needs, especially during summer events . like the MEOX Mobile solar container.
- Hybrid power systems: Combining batteries with small, efficient generators reduces both emissions and fuel consumption (Intelligent Controls).
- Grid connection upgrades: For recurring events, investing in temporary or permanent grid connections can eliminate diesel use altogether.
The Opportunity for Change
Shifting to greener energy sources at outdoor events is not just an environmental imperative—it’s also an opportunity for positive branding, local innovation, and healthier communities. The growing demand for sustainability on behalf of the participants has become a trend that facilitates, or even forces the implementation of sustainable principles at events (AKJournals). By taking leadership on this issue, cities in the ROHU region can set an example for the rest of Central and Eastern Europe.

- Encouraging collaboration between municipalities, technology providers, and event organizers to lower barriers to clean energy adoption.
Conclusion: Celebrating Sustainably
Outdoor events are vital to the culture and economy of the ROHU region. With modern technology and clear policy support, these events can maintain their vibrancy while drastically reducing their environmental footprint. The transition from diesel to renewable-powered celebrations is not only possible, but necessary—and it starts with awareness, innovation, and leadership from every corner of the community.
