The Earth Day 2025 with climAD

Together for a Sustainable Future: On April 22, 2025, Earth Day was celebrated – a day that reminds us of the importance of taking responsibility for our planet. Green City Solutions and climAD used this special occasion to collaboratively disseminate sustainable messages in innovative ways with partners such as LichtBlick SE and KoRo . With bio-digital advertising spaces that combine technology and climate responsibility, Earth Day 2025 became an impressive example of sustainable communication.

Sustainable Messages on Bio-Digital Advertising Spaces

Our CityBreeze – a unique combination of a moss wall and a large-format screen – offered the perfect platform for impactful campaigns in conjunction with climAD . These bio-digital advertising spaces combine media visibility with genuine climate responsibility. They demonstrate how Digital Out of Home (DOOH) can be used as a sustainable communication channel to bring climate and environmental issues directly into people’s everyday lives.

As LichtBlick SE announced, “Digital Out of Home (DOOH) is one of the most environmentally friendly advertising media in the marketing mix. On the occasion of Earth Day, we are going one step further together with climAD.”

LichtBlick SE: Bag Something for the Climate While Shopping?

The LichtBlick campaign was themed “Bag something for the climate after shopping” and impressively demonstrated how DOOH not only creates attention but also actively contributes to improving air quality.

Marc Wallraff, CEO of LichtBlick SE, emphasized in a LinkedIn post:

“Digital Out of Home (#DOOH) is one of the most environmentally friendly advertising media – and there’s even more to it: on the back of the steles where our campaign is currently running, real moss is growing. It not only looks good but also binds CO₂ and improves air quality. Great idea from climAD.”

Nadine Usadel, Senior Media & Campaigns Manager at LichtBlick SE, also highlighted the special feature of the campaign:

“[…] on the back of all the steles, there isn’t more advertising as usual. But moss. Real, living moss. Because it binds CO₂ and ensures good air“.

The campaign was visible from April 14 to April 22 in shopping environments in cities such as Berlin, Braunschweig, and Bremen, especially in shopping centers. Nadine Usadel further explained:

“We are picking up on the situation in which people find themselves – shopping. And giving the matter a sustainable twist. With a wink, without a wagging finger,” “Because our consumer decisions, such as switching to 100% green electricity, have a direct impact on the planet.”

KoRo: There is Only One Earth …

Another highlight of Earth Day 2025 was the collaboration with KoRo. The company brought its message “There is only one Earth with KoRo snacks – protect it!” to the innovative DOOH displays of climAD. These displays, equipped with integrated moss filters, actively purify the air and thus contribute not only to the visibility of the message but also to improving air quality.

KoRo teilte auf LinkedIn:
“For Earth Day – a global reminder of the importance of environmental and climate protection – we are pleased to be working with climAD. Our message will be shown on these innovative displays at more than 20 locations throughout Germany until April 22.”

With this campaign, KoRo impressively demonstrated how modern brands can take responsibility and at the same time convey a clear, sustainable message – without greenwashing, but with real impact.

DOOH: A Sustainable Communication Channel for Climate and Environmental Issues

The campaigns for Earth Day 2025 have vividly demonstrated how DOOH can be used as a truly sustainable communication channel. Our environmentally friendly DOOH screens not only offer a high reach but also the opportunity to combine media visibility with genuine climate responsibility. The combination of innovative technology and natural elements such as moss makes our bio-digital installations a pioneer for sustainable advertising.

Thanks to Our Partners: Together for a Better Future

Marc Wallraff and his Lichtblick team have impressively demonstrated with their campaign tailored to the shopping environment how DOOH not only creates attention but also actively contributes to improving air quality.

KoRo has proven with the message „With KoRo snacks there is only one earth – protect it!“ how brands can take responsibility, prove humor, and at the same time show a clear attitude.

Because, as Christian Heidemann, Creative Director at Lichtblick SE, emphasizes: „[…] let’s be honest – the earth gets along quite well without us. But we don’t without it.“

Also GOT BAG finds: “THE EARTH IS WORTH MORE.”
