About Klima

Klima is a climate app that allows you to become carbon neutral with the tap of a button. Here’s how it works:

  1. Calculate your carbon footprint.

  2. Offset it by supporting verified climate projects.

  3. Live carbon neutral, see your impact grow, and inspire others.

Klima is about more than just personal carbon offsets. Our mission is to turn climate neutrality into a mass movement and unleash the power of individual action at scale.

That’s why we’ve not only created the most lovable and empowering user experience for carbon-neutral living, but also one that multiplies your impact by allowing you to invite your friends to start living carbon neutral today.

Think about it this way: The more people share their commitment to the climate, the more people join — and the more climate-conscious living will become the new normal. Everyone benefits.

Together, we can transform individual action into collective impact and make a measurable difference against the climate crisis.  

Klima is a social startup from Berlin, with a growing team of mission-driven designers, engineers, and changemakers from 5 continents. Together, we’re united by one goal: making a dent in the fight against global warming. 

Klima was established  in 2019 by founder-trio Markus Gilles, Jonas Brandau, and Andreas Pursian-Ehrlich. They've created tech-for-good for many years, helping to promote civil discourse, quality journalism, and women’s empowerment. They started Klima to commit their resources to the most important challenge of our lifetime and empower others to do so as well.

Klima was founded to create the biggest possible impact for the climate — collectively and individually. Here’s how that breaks down financially:

  • 10% running cost: To make Klima possible, we use 10% of what we make to cover our running costs including IT development, project selection, and infrastructure.

  • 70% individual impact: This goes directly to your personal offsetting projects, making sure you’re carbon-neutral from day one. These funds plant trees, expand solar energy access, and provide clean cookstoves to thousands.

  • 20% collective impact: No one can solve climate change alone. That’s why we invest 20% into impact marketing, aka spreading the word and getting more people involved. That way each user multiplies their own impact by reaching others. Read more on our collective impact strategy here.

Achieving maximum impact also means that we don’t want to exclude anyone for financial reasons. If you can’t afford a complete plan, send us an email at and we’ll provide you with a custom reduced plan, free of running costs and the collective impact contribution.

We’re not, and here’s why: We have years, not decades, to reverse global warming. This means we need to reach as many people as possible as quickly as possible, or in other words, we need to scale fast. 

One surefire way to do that? Put investment dollars into a robust, impact-first business model. That way we make sure to achieve the biggest climate impact we can.

We’re also a certified B-Corporation, a new kind of business that balances business and purpose. After all, we consider the climate to be our biggest shareholder — and a healthy planet is the best dividend.

Absolutely! At Klima, we deeply care about neutralizing your emissions from day one. But it doesn't stop there. 

Our long-term goal is to reach a zero-carbon world. That's why we'll also help you further reduce your footprint. From tips on what to do in your day-to-day life to combat the climate crisis, to what's the most important political action you and your friends can take, we'll share regular climate-healthy recommendations.

The great news is that most things that are good for the climate are also good for our health (and our wallet). And every time you reach a personal reduction milestone, you can reduce your offset amount, too.

About Offsets

CO2e — or carbon dioxide equivalent — describes the global warming potential of all greenhouse gases. In other words, the impact of different greenhouse gases is expressed in terms of the amount of CO2 that would result in the same amount of warming. Put simply, CO2e gathers all greenhouse gases into one place. As human activities don’t only generate carbon dioxide, CO2e is a more accurate way to measure our emissions. If you'd like to learn more about this term, take a look here.

All the solutions on Klima rank among the most impactful ways to fight climate change worldwide, as identified by Project Drawdown, a nonprofit that conducts rigorous assessments of climate solutions and is a leading resource in our field.

Our offsetting projects meet the highest international quality standards for certified carbon offsetting and are verified through the Verified Carbon Standard, or the Gold Standard developed by WWF and other NGOs.

On top of that, all our projects provide additional benefits to their local communities that align with the United Nations Sustainable Development Goals. These range from combating poverty, protecting endangered species, empowering female entrepreneurship, or advancing access to health care and education.

There is no single solution to stop climate change — it’s going to take creativity, dedication, and action from us all. Carbon offsetting is one big piece of that puzzle.

While political regulation or cleantech inventions can take decades to be implemented, offsetting allows you to take your footprint off the planet. right. now. That’s a big advantage and it’s why Klima starts here and then shares ways to reduce your footprint further.

We encourage the Klima community to adopt climate-healthy lifestyles and support political action to fight climate change. It's crucial that we work on every front, pushing for short-term and long-term solutions that make our societies carbon neutral.

We have structured Klima’s offset portfolio around three clear and crucial impact areas that we’ll all need to tackle in order to solve climate change in a sustainable, efficient, and just way. These three areas are 

  • Nature: planting trees

  • Tech: solar energy

  • Social: clean cookstoves

By combining natural, technological, and social solutions, we empower holistic climate action that revives our ecosystems, pushes green innovation, and benefits communities. You can read more here.

Impact transparency is one of our core guiding principles. Klima allows you to see directly and in real-time what positive effect your commitment has on the planet and how that impact grows. 

Not only do you get live updates on the overall CO2e you’ve reduced, we also break down to the individual unit where that reduction comes from, be it the number of trees planted, kilowatt-hours of green energy produced, or clean cooked meals provided by your support. Based on your input, you’ll even learn how to live a more climate-healthy lifestyle along the way. The result is incredibly empowering and shows that every single action counts.

We calculate your footprint based on a well-defined set of lifestyle questions that we combine with a national baseline of the country you live in, to get a close estimate based on your individual circumstances and personal choices. 

All questions are designed to allow for intuitive responses via a multiple-choice chat interface, and the setup process takes about 3 minutes. Examples for questions are “What best describes your diet?”, “What kind of shopper are you?”, or “How many flights do you take per year?”

The CO2e numbers show the verified emission reductions as independently monitored and certified by our certifying partners (Gold Standard and Verified Carbon Standard).

The individual tree numbers are reported to us directly from your project developers, for Madagascar as direct counts, for Panama and Tanzania on a tree per ton basis over the project lifecycle.

The solar energy and meal numbers are calculated based on each project’s certified CO2e emissions and documented emission factor per unit (Mwh / stoves), adding in the case of cook stoves our own conservative calculations of meals per week per stove.

All final numbers are then discounted by 20% to be conservative. Real numbers are therefore likely higher.

Actually, the opposite is true. Studies show that people who offset their carbon emissions act not less but more climate-friendly in other parts of their lives, too. That makes sense: When you’re personally invested in a cause, you want it to succeed.

Surveys show that most people are worried about the climate, but aren’t sure how to help. There’s a massive gap between willingness to act, and avenues of action.

That's also why much of Klima is dedicated to sharing strategies, support, and information on lowering your climate footprint overall. The most effective way to take individual climate action is to offset your footprint, and then work on sustainable solutions to shrink your total emissions in the long-term. We're here to help on both fronts.
