We use precise performance and energy measurements to optimize the efficiency of our energy supply. We identify potential savings and reduce the consumption of fossil fuels by increasing the use of alternative energy sources. In 2025, we used a battery for the first time to supply our stage with fixed power.

Since a large part of our festival's CO2e emissions are generated in the area of travel & transport, we are working on a holistic design of mobility concepts for you. But we also want to improve in the area of logistics. That's why we are working with research institutions to develop future-oriented solutions for festival logistics. We are also tracking our CO2e emissions in this area in particular. If you come across a survey on travel behavior, please take part. This will help us for future optimizations.

In line with the concept of the circular economy, we strive to return all materials used to the cycle and minimize the use of new resources. Our partners support us in this: Foodsharing, Utopia and eSKa. We also ask our brand partners to completely avoid the use of single-use plastic.

In cooperation with the Gastrobüro, which provides you with food throughout the site, we are expanding our climate-friendly food offer. In 2023, 53% of the food sold was vegetarian or vegan. You make the decisive difference here! We integrate regional suppliers where possible to further increase the sustainability of our catering. Find out more about Gastrobüro's sustainability here.

For every ticket sold, €1 goes into splash!'s sustainability budget. Part of this budget is invested directly in more sustainable infrastructure and measures on the festival grounds. The remainder goes toward sustainable initiatives. Together, we are setting an example for environmental protection and social responsibility.

For the first time in its history, splash! is part of a research project. We want to reduce our emissions and are working together with partners from science and research, from the festival sector and from the private sector to collect and model energy, mobility and consumption data and to develop a planning platform for sustainable festival logistics.

FAIROPOLIS is the place where committed and creative people come together and share their visions of a better future - with each other and with you. Together with various organizations, we have created a place where you can find out about interesting topics and take part in workshops. In addition, we offer you further activities and program items during the festival! At the same time, we are also creating an oasis to immerse yourself, feel good and recharge your batteries away from the exciting festival madness with various program items, workshops and exciting discussions with the NGOs.
