We communicate Sustainability
By making complexity doable.
GreenroomVoice (GRV) is an agency specialising in untangling sustainability — aligning action, strategy, and storytelling for Outdoor Brands, Suppliers and Organisations to make impact visible.
The GRV Sustainability Showcases
At relevant outdoor and textile fairs of the year, we create spaces where sustainability comes to life.
Our showcases connect the dots—between service providers, brands, suppliers, and organisations—to show how real progress happens: through collaboration, transparency, and aligned action.
Because sustainability is a team effort.
ISPO 2025
SUSTAINABILITY SOLUTIONS
PROGRAM
Sustainability Solutions at ISPO/ Munich
Since 2010, we’ve curated this dedicated space for visibility, collaboration, and progress in sustainability. Over the years, it has grown into a magnet for innovation — from renewable materials and circular economy practices to groundbreaking service providers. In 2025, the platform returns with a broader scope, new formats, an integrated stage, and more dynamic opportunities to connect.
Sustainability Solutions at OutDoor by ISPO
In 2026 OutDoor will take place in Lago di Garda in Italy!
For many years, we’ve curated the Sustainability Hub at Outdoor — now evolving into Sustainability Solutions. Especially in times like these, it feels more important than ever to stand together as an industry. We are all dealing with the same challenges — and there are solutions. By learning from each other and creating synergies, we can make it happen.
Sustainability Lounge at Performance Days / Munich
Step into the heart of sustainability as our partners showcase the latest advancements in sustainability and outline their vision for driving progress in the field. Join us for an immersive experience designed to foster meaningful exchanges and inspire collective action.
Sustainability Lounge at Functional Fabric Fair / Portland Oregon/ USA
As we look ahead, collaboration will be key to advancing sustainability. The Sustainability Lounge provides the ideal platform for this. Feedback from our partners reaffirms this sentiment. It's inspiring to witness guests naturally engaging in dialogue, sparking discussions, and forging new connections. With its open yet intimate atmosphere, the Lounge facilitates workshops, networking sessions, and lays the groundwork for future collaborations.
We love themed posters!
Maybe you want one, too?
Sustainability is full of complexity—but it doesn’t have to be confusing.
With our themed GRV posters, we break down the big topics, connect the dots, and show how it all fits together. Whether it's supply chains, legislation, or industry topics —we turn tangled issues into clear, visual narratives.

We are the team behind the New Horizons podcast
When Globetrotter Ausrüstung asked us in 2020 to support the launch of their new sustainability podcast, we were beyond excited — it felt like a dream come true. With decades of experience in magazine publishing, storytelling is in our DNA. We love creating content that truly connects with people: real stories, lived experiences, and voices that inspire.
Our guests at the “New Horizons” Podcast bring insights, learnings, passion, and expertise to every conversation. We are speaking with change-makers and doers, well-known personalities as well as the quieter voices working behind the scenes.
We learn something new in every episode — and we hope you do too.
What People Are Saying about working with Us
“For over 10 years, GreenroomVoice has been supporting the implementation of the Sustainability Hub at ISPO Munich and, since 2019, at OutDoor by ISPO. We value their technical expertise and trusting cooperation. In cooperation with GreenroomVoice, the Sustainability Hub can continue to develop and is an important meeting place within the industry.”
— Lena Haushofer, Exhibition Director ISPO Munich & OutDoor by ISPO
“Your work and expertise are simply superb, and we can always rely on you – that is something that really sets you apart and is unfortunately not always a given when working with agencies and other external partners!”
— Miriam Ersch-Arnolds, PR Manager, Globetrotter Ausrüstung
“The workshops on New Legislation on Communication were super-beneficial for my task of inspiring companies to take concrete climate protection measures. The team of Ohana consulting and GRV presented the legislative initiatives under the EU Green Deal in an understandable way, with a lot of insider knowledge and precisely the right level of detail. As a result, I can now explain the need to collect climate protection data, plan and implement reduction measures, and communicate transparently, more comprehensively and stringently to potential customers.”
— Kai Landwehr, Director Global Marketing, Co‑Executive Director Foundation myclimate
