All the services of the Klima-Taler network
Driving sustainable mobility
The app automatically detects how you get around—on foot, by bike, by bus or train, or by car. Travel in a climate-friendly way, save CO₂, and earn Klima-Taler as you go.
One Klima-Taler equals 5 kg of saved CO₂. In the app, it fills up segment by segment—like a progress bar that rewards you for being on the move. Once it’s full, the Klima-Taler goes into your digital wallet and can be redeemed.
That’s how everyday journeys turn into a game with impact—for anyone who wants to make a difference while having fun.
Making resource savings second nature
The app also helps you save electricity, heating, and water. You can connect digital or analog meters via a gateway or by photo scan.
Users receive a personal monthly budget. Stay under it and you earn Klima-Taler. Go over it and you’ll get tips on how to reduce consumption. A comparison with similar households shows where you stand—and adds extra motivation.
Collect it. Keep it. Send it.
Your digital wallet keeps all your Klima-Taler in one place and shows, at a glance, when and where you redeemed them.
Sharing is just as easy: send a wallet transfer link, choose the amount, and done. Turn your climate currency into something you can collect—and share—in seconds.

Create and add your own actions
Add custom activities to the app and incentivize participation with Klima-Taler. From your city admin console, generate QR codes that, when scanned, automatically credit your chosen amount of Klima-Taler.
Climate Treasure Map
Your city’s guide to sustainability. In the app, every sustainable place is put on the map — from cycling infrastructure and sustainable shopping to return and drop-off points for reusable containers, drinking fountains, and heat-relief spots.
Municipalities can add their own locations with just a few clicks.
Highlights: Participating retailers and institutions are shown on the map.
In-app routing guides users directly to each location.
The “Climate Treasure Map” can be embedded as an interactive iframe on your city website.
New challenges every month
Monthly CO₂ team challenges with four leaderboards
- Cities & regions
- Schools
- Companies
- Open teams
Scoring is based on the amount of CO₂ saved. Users choose their own teams. The app shows the top 10 teams and each user’s team rank. Friendly competition is fun—and keeps motivation high.
Tip: It’s easy to set up custom leaderboards, for example across all municipalities or all schools in your city or region.

Embed the dashboard via iFrame
See your progress live CO₂ savings, active participants, Klima-Taler earned, and more. Embed the dashboard on your city website with a single iframe and turn climate progress into something everyone can see.
Tip: From the admin console, you can spin up separate dashboards for local schools or companies.
Reduce it. Then self-offset it — with Klima-Taler
The greenest choice is the one you don’t need. Flights not taken, car trips skipped, heat, power, and water you never use. But life happens, and emissions do too.
We make them visible and manageable. The “Make it disappear!” widget shows your CO₂ and lets you offset it with Klima-Taler. Every Klima-Taler equals 5 kg of CO₂ saved, so you can match like-for-like and bring your balance down. Seeing progress turns reduction into a habit and collecting Klima-Taler into a motivator.
Set Your Vehicle’s Consumption
Car trips are calculated using the average CO₂ emissions per kilometre from the German Environment Agency (UBA). You can adjust the settings to match your car’s fuel type and consumption. The available options are petrol, diesel, standard electricity mix, green electricity, CNG and LPG.
You can also factor carpooling into the CO₂ calculation.
Provide Heat Protection Measures
During the hot summer months, the effects of climate change are especially noticeable. To make it even easier for you to protect your residents from rising temperatures, we’ve expanded our climate action app with a dedicated heat safety section.
Anyone who follows the tips and advice will get through hot days more safely. They also earn Klima-Taler as extra motivation. Learn more about the heat safety measures in the Klima-Taler app here.
Show Public Drinking Fountains on the Map
To support your heat safety work, the map shows public drinking water fountains across your city. You can also mark shops and municipal facilities where residents can refill their bottles for free. This makes it easier to stay hydrated on the go and reduces plastic bottle use.
You can highlight “no go areas” on the same map. These are places to avoid during heat waves because of very high temperatures and a lack of shade.

Questions about Klima-Taler? Let’s talk.
Let’s plant trees together
Turn miles into trees: participants have 21 days to complete 200 km by walking or cycling. Hit the target and a tree is unlocked and planted in a climate project. Miss the deadline and progress resets—so the challenge begins anew.
Unlock awards and badges
Participants earn badges for hitting milestones. These thoughtfully designed awards keep people engaged over time. Badges are a key element of the gamification model behind the Klima-Taler app’s success.
In-app insights
In the app, every participant gets a quick overview of their year-to-date results. They see how much CO₂ they have saved themselves and what we have achieved together as a community. The app also shows where those savings come from:
- Walking
- Cycling
- Using public transport
- Climate-friendly activities
Extended evaluations for cities and districts
On-demand insights for your city
Get on-demand access to anonymized insights for your municipality. Download every report as a chart and as a CSV export. No coding or data skills required.
- Modal split analysis for your region (distance, trip segments, time)
- CO₂ emissions over time
- Average kilometres per user
- Heatmaps of cycling, driving, and public transport use as interactive HTML files (one per mode)
Tip: Improve public transport access to business parks. Reduce winter road salt use. Cut costs with urban planning based on up-to-date data.
Public outreach toolkit
Good communication is key to launching Klima-Taler well. Our all-in marketing package has you covered from outdoor ads to an embeddable data dashboard for your website.
It saves time and comes at no extra cost beyond the annual Klima-Taler fee, starting at €1,990 per year, scaled to your municipality’s size.
The Klima-Taler network
Klima-Taler brings together apps, a merchant portal, data interfaces, and a municipal admin console — one network built for local climate action. Today, 50+ municipalities and regions, about 750 partner locations, and 125,000+ citizens are active. Our monthly network sessions help municipalities learn from each other, roll out new features, and continuously improve the Klima-Taler program together.
Invite friends functionality
Invite friends and earn together: when a user invites someone who joins, both the inviter and the new participant receive a Klima-Taler. Share the invite by email, SMS, or social media—or let people scan a QR code from your phone. The link sends them straight to the right app store to install the Klima-Taler app. As soon as they accept the invite, the Klima-Taler is issued automatically.
In-app communication channels
Use the app’s news feed to reach your teams instantly. Share updates on campaigns, funding, and events across your municipality. Grow a dedicated climate action community. Stop starting from scratch with every message. Stay independent from large U.S. platforms where organic reach is limited.
Reach your teams fast with push notifications
Reach your city team exactly when it matters. Push notifications show on the lock screen even if the app is not open. Admins create and send messages to their own city team and schedule them for a specific time. Automated updates on results, challenges, offers, and awards keep momentum high. Participants control what they receive in Settings. Every notification remains available in the app’s News section.
