2zero in the press

NDR report on the big Climathon in Schleswig-Holstein 2025

The Climate Marathon competition runs for 42 days in Schleswig-Holstein. The app 2zero shows how much CO₂ is produced through certain activities and how much can be saved.

App-Test »2Zero - sustainable together«: run the Climathon!

Climate protection is especially fun as a team effort. And in the case of 2Zero, the team is your own municipality or your group of colleagues. With challenges and local activities, the app aims to motivate people to take a strong stand together against climate change.

Climathon: Program for climate marathon in Flensburg

The program for the climate marathon was presented at Flensburg City Hall. Over the course of 42 days, residents of Flensburg can take on 40 climate challenges in app-based competitions. The goal is to save as much CO2 as possible.

Halfmarathon at the Kitchen Table

You can take part in the climate marathon without any training — though it can still be challenging.

Reducing carbon footprint through App-based personal challenges

Welcome to our spotlight series. This week we feature Max Pinkert, CEO and Co-Founder of 2zero, an app that helps individuals and businesses reduce their carbon footprint by completing personal challenges.

Three cities, one bet! Who can save more CO2 in the north?

History and Origins

Climate protection and technolgy?

In 2016, Moritz Morgenroth and Emil Bergold founded the company twigbit, driven by the vision of developing digital solutions that are both efficient and customer-focused. As a mathematician and computer scientist, respectively, they were entering a world they knew well — one where projects quickly took off. The young company twigbit began to establish itself.
A year later, the United Nations’ Sustainable Development Goals (SDGs) were released to secure our natural resources for the long term in a sustainable way. They laid the foundation for the sustainable development of our society. The SDGs, the Paris Climate Agreement, Greta Thunberg, and the Fridays for Future movement all contributed in the following years to raising broad public awareness of climate change. The topic of (ecological) sustainability — in all its dimensions — became a widespread topic of discussion.

How did the idea for 2zero as a new, independent company come about?

Until 2020, as twigbit, we didn’t fully realize how a digital technology company like ours could contribute to achieving the SDGs. That changed with the founding of worldwatchers in 2019.
Worldwatchers was based on the idea of offering a kind of “Weight Watchers for the climate.” Seeking a technological partner to help make these solutions appealing — for example, in the form of an app — led to a collaboration between worldwatchers and twigbit.
From 2020 onward, worldwatchers and twigbit worked together: we handled the technological development, while worldwatchers focused on content. Companies and municipalities became key clients. Their feedback, combined with our experience, gave us new insights into the relationship between sustainability and digital products.
In addition to developing sustainable tech, we identified opportunities and solutions that we could implement quickly and user-centrically based on our existing expertise. Early projects included an intuitive CO₂ calculator and the visualization of emissions and savings potential.

Founding of 2zero

At the turn of the year 2021/2022, we founded 2zero as a standalone startup spun out of the software agency twigbit. This marked the beginning of our next chapter — building on the experience with worldwatchers and working toward the SDGs with a sustainable vision alongside our customers.
Julius, our Sales Manager, says: “We offer you a user-friendly app that lets users dive in quickly, playfully, and effectively!”
In concrete terms, our digital platform works in the background to evaluate and analyze each person’s ecological footprint in a simple and intuitive way.
To actually reduce CO₂e emissions, the app provides incentives, actions, and everyday tips.
Our target group includes both private and business clients, with an initial focus on companies and municipalities. Our ever-growing team is dedicated to this mission!

What motivates our founders?

"I believe climate protection shouldn’t just be fun — it has to be fun! 2zero isn’t the first startup I’ve founded, but it’s the one where I can truly pursue my greatest passion: combining technology and sustainability. Plus, it’s endlessly exciting and inspiring to turn a digital product idea into reality through programming — and to make it available to others in a short time."– Moritz, Co-Founder of 2zero

Protecting the climate together, playfully: Shape the shift to a more sustainable future with 2zero

2zero, an innovative climate protection startup from Berlin, has made it its mission to make the world a little better — both in everyday life and in the workplace.
With its climate protection app, 2zero has already supported over 50 companies and municipalities on their path to climate neutrality. The company takes a gamified approach to measuring and reducing CO2 footprints.
The 2zero app is a true all-rounder: it measures your CO2 footprint and motivates users through a variety of challenges to reduce it. Users can earn points by, for example, riding their bike to work instead of driving, or by cutting down on meat consumption. And the best part? Every completed challenge earns great rewards.
The story of 2zero began with founders Moritz Morgenroth and Emil Bergold, who originally worked in software development. Shortly after the UN’s SDGs were published, they set out to ensure their technology could help achieve these goals. In collaboration with worldwatchers — the “Weight Watchers for the climate” — 2zero began developing digital tools to measure CO₂ emissions and highlight savings potential.
Over time, a growing team of passionate climate advocates came together, and 2zero evolved into a key player in climate protection. Today, 2zero offers initiatives like the “Klimathon”, a fun and engaging way to get started with climate action.
The 2zero app is full of tips and tricks for more sustainable habits in everyday life.
Major cities like the state capital Kiel and entire districts like the District of Munich have already teamed up with 2zero to run climate protection campaigns. With 2zero’s digital tools, people can engage with climate protection in a playful way and foster a long-lasting culture of sustainability within their communities.For more information about 2zero, visit: https://www.2zero.earth
