VIECON Goes Greener
Sustainability at VIECON: How the location is becoming greener step by step
Sustainability is gaining importance across the event industry. At VIECON, it is not just an aspiration but an ongoing development process that is visible across the grounds. Numerous initiatives ensure that the venue remains ecologically future‑ready while offering a pleasant environment for guests, partners, and employees.
Green courtyards: New spaces for well‑being in an urban setting
The courtyards at VIECON have undergone extensive revitalization at the end of 2025. Overgrown areas have been transformed into structured, low‑maintenance green spaces with shrubs and perennials. These redesigned courtyards improve the microclimate, create natural shade, and offer inviting areas for visitors and employees — an important building block for greater sustainability at the venue.
Natural enhancement: From ornamental basin to green area
The former ornamental basin has been redesigned as well. Instead of a water‑intensive fountain, a planted green area now promotes biodiversity. It provides habitat for beneficial insects and helps conserve resources. This zone also acts as a natural cooling area, noticeably reducing the urban heat island effect at the forecourt of Hall A. As a result, it enhances both the overall climate impact and the comfort of the entire area.
Sustainability on the roof: Five beehives for BEECON
A highlight of the latest initiatives is the bee project. Five beehives have been placed on the roof of the Congress Center. The colonies collect nectar in the nearby Prater and produce our very own BEECON honey. The initiative is professionally guided by master beekeeper Thomas Zelenka. It makes sustainability tangible and demonstrates the valuable role urban areas can play in supporting biodiversity.
Vertical greening: Hall A grows upward
The new green façade on Hall A is another visible milestone. Twenty‑six planters with a total of 78 climbing plants will gradually transform the hall’s exterior wall into a vertical green space. This provides natural cooling, binds CO₂, and enhances VIECON as an attractive, climate‑active location in the urban landscape.
Green electricity & modern lighting: Energy efficiency in focus
VIECON is also taking decisive steps in its energy strategy. The entire site is now powered 100% by green electricity from hydropower. This shift significantly reduces the CO₂ footprint and ensures that all events take place on a sustainable energy foundation.
At the same time, the entire venue — except for Hall D — has been converted to energy‑efficient LED lighting. LEDs consume far less power, have a longer lifespan, and notably reduce energy demand during daily operations.
Commitment to global climate targets: Net Zero Carbon Event Pledge
Beyond construction and ecological initiatives, VIECON is also demonstrating strategic responsibility. By signing the Net Zero Carbon Event Pledge, the venue commits to transparently measuring emissions, actively reducing them, and reporting progress regularly. The goal is to achieve climate‑neutral operations by 2050 at the latest — in line with the Paris Agreement.
Sustainability in detail: From recycling mats to the Christmas tree
Many smaller steps further support the sustainability strategy. The new GreenMats in the entrance areas are made from recycled PET bottles, reduce water consumption during cleaning, and lower CO₂ emissions.
Seasonal decisions are also made consciously: In 2025, a regional potted Christmas tree was placed in the reception area. The tree is cared for after the season, reducing waste and enabling multiple years of use.
Conclusion: A venue that takes responsibility
VIECON shows how diverse sustainability can be — from green façades and biodiversity projects to strategic climate commitments. Step by step, a venue is emerging that combines ecological responsibility with urban quality of life, making a valuable contribution to a sustainable future for events in Vienna.
