We’re all deeply concerned about the effects of climate change on people and the planet, but we haven’t given up the fight. And we mean business. 

Who are we?

The Club Leaf app is an easy-to-use mobile application that helps you to get on your way to becoming carbon neutral. It’s easy! Just download the app, measure your carbon footprint, reduce your emissions using our Green Tips and Challenges, and support our un-be-Leafable accredited climate offset projects. Join us today and start your sustainability journey! 

What's the Club Leaf app?

Carbon neutral is when there is a balance between the amount of carbon that is emitted into the atmosphere and the amount of carbon that is absorbed from the atmosphere (stored in the oceans, soil, and forests). To create a carbon neutral world, it’s essential that we reduce carbon emissions and increase carbon storage (also known as ‘sequestration’).

What's carbon neutral?

Our vision is to inspire and empower people around the world to live a carbon neutral life and show that collective action can have a big impact in combating climate change. Our mission is to partner with the world’s most impactful environmental projects.

What's Club Leaf's mission and vision?

Our founders Roelien Ruys and Aron Löcsei first met at university at a time when everyone was watching Friends and playing snakes on their not very smart phones. Fast forward two decades and the friends are today leading a profit-for-purpose company that is quite literally helping people save snakes (and all things people and planet) on their smartphones! Here’s their story.  


After graduating, Roelien and Aron both enjoyed successful careers in business in their respective fields [in the UK, the Netherlands and beyond], advising companies on how to innovate and grow. But something was missing. As passionate environmentalists and parents, both wanted to use their experience and expertise in a different setting to make the world a better place today and for future generations. They searched for a solution and searched some more. But they could not find one, so decided to make their own.  


Their goal? To create a platform that would enable people around the world to make a small difference individually, and a massive difference collectively, in combating climate change.  


With a lot of beLeaf, backing from investors, and a crack force team that shared their passion, Club Leaf and the Club Leaf Community was born.  


With much more to come, the Club Leaf story has just begun.  

What's the story behind Club Leaf?

No, we’re a profit-for-purpose organization. We have big plans and being a charity would, for instance, limit our ability to access investment from large financial backers. This would in turn hamper our ability to grow quickly and reach sufficient scale to have a truly global impact on the environment and reversing climate change. What’s more, our many decades’ shared experience in the corporate world has taught us that the best way to encourage companies to protect our environment, rather than destroy, is by incentivizing them. 

Is Club Leaf a charity?

As a profit-for-purpose organization, we are proud to be open about how, where and when we invest every cent, euro, dollar and pound of your money.  


75% of our funds go directly to funding the best environmental projects that help to protect and restore the world’s ecosystems and promote renewable energy innovation. All of our projects contribute to multiple UN Sustainable Development Goals by improving the livelihoods of local communities. We are guided by the very latest scientific research, and only select the most effective projects in combating climate change. What’s more, each and every one of our projects is verified by the highest voluntary carbon offsetting standard. 

Check out our impact so far on our Club Leaf Impact Ledger.


The remaining 25% of our funds cover everything else. We use it to pay our talented team, develop our platforms, such as this website you’re reading, and last but not least, find amazing new projects for you to support in your journey to go green.


We take being open and transparent about our finances very seriously. If you’re interested, we’ll be publishing our progress on this website every quarter so you can see exactly how and where we’re using our funds.

How do you use my money to help combat climate change?


A carbon footprint is the total amount of emissions that result from our actions. This is calculated on a yearly basis. In other words, a carbon footprint is the total greenhouse gas (GHG) emissions from an individual, organisation or product, expressed as kilograms of carbon dioxide equivalent. You’ll see this in the Club Leaf app expressed as kg CO2e. 

While it’s impossible to reduce your emissions to zero overnight, if we all make small changes, we can make a huge difference together. Download our app and get started today!

What's a carbon footprint?

The purpose of calculating carbon footprints is to quantify where our emissions come from and to give people a better understanding of how this is split across different categories. This helps people to see how their footprint compares with the average footprint in their country, and which categories have the biggest impact. Once we better understand our carbon footprints, it’s easier to reflect on our lifestyles and evaluate where we can reduce our impact. We then share suggestions on the best ways to get started and start changing the world!

Why do you measure my carbon footprint?

Our unique carbon calculator is quick and easy to use. By answering a short set of questions you get a picture of your carbon footprint. Based on the data you input, we calculate your footprint using emission factors to transform each action into kg/CO2e. The general calculation is: Activity data multiplied by emission conversion factor (EF) = GHG emissions. This helps you better understand which of your activities consume most resources and helps us provide you with the right suggestions to reduce your carbon footprint and help combat climate change. 

How does Club Leaf calculate my carbon footprint?

Emission factors describe the amount of greenhouse gas emissions emitted as a result of energy use. An emission factor is a value expressed in kg/CO2e, which is multiplied by how much of the energy source you consume. Emissions factors vary for different types of energy sources (coal, gas, oil) or different types of fuel (diesel, petrol, kerosene) for transport, heating and electricity use.

What is an emission factor?

Club Leaf’s carbon calculator has several categories: at home, food, getting around, shopping and travel. For each category, we ask questions that relate to your consumption data, which gives us part of the information we need to calculate your footprint.

Your consumption data is then combined with emission factors from sources including DEFRA, the European Commission, ERS/USDA, LCA and EIO-LCA data, official government sources, energy and environmental agencies and scientific journals. Emission factors enable us to transform your consumption into kg of CO2e.


We also used the World Bank’s CO2 per capita data to give you a comparison between your personal footprint and the average person’s footprint in your country of residence.

Where does the carbon footprint data come from?

Our Green Tips are calculated in collaboration with our environmental partners. We use data from scientific journals and other leading scientific sources on climate change to calculate the potential reductions that each Green Tip can bring about.

How was each Club Leaf Green Tip calculated and where does the data come from?


Carbon offsetting sounds complicated, but is actually quite simple. Many human activities like driving a car and industrial activities like running a factory emit harmful carbon and greenhouse gases into the atmosphere, contributing to climate change. 

These emissions can be compensated against by avoiding, reducing or capturing carbon and greenhouse gases elsewhere. A carbon offset credit is used to represent this emissions reduction, with 1 credit being equal to 1 metric ton of carbon, or the equivalent amount of greenhouse gases. This is expressed as CO2e. 

The voluntary carbon offset market enables many different groups including individuals, companies and nonprofit organizations to offset their emissions.  


What's carbon offsetting?

It’s not easy to reduce your carbon footprint completely to zero - that’s why our Club Leaf app enables you to offset your remaining carbon emissions - making a positive difference to the environment when our emissions can’t be avoided.  By funding the world’s leading carbon offset projects, we’re able to help protect and restore the world’s ecosystems, promote renewable energy innovation and improve livelihoods of vulnerable communities. 

Why do we use offsetting?

We choose our projects based on need and effectiveness. All contribute to multiple UN Sustainable Development Goals by improving the livelihoods of local communities. We are guided by the very latest scientific research, and only select the most effective projects in combating climate change. What’s more, each and every one of our projects is verified by the highest voluntary carbon offsetting standard, for people and the planet. 


Our projects must meet a strict set of criteria: 


Our portfolio is structured around projects that include both short- and long- term benefits, that avoid, reduce or store emissions, and that benefit both people and the planet. These three areas are land, energy and community-based projects

How do you choose projects?

We love trees. And we love supporting projects that help to plant thousands of hectares of them too. But combating climate change is about far more than just reforestation projects alone. Supporting a whole range of projects that generate carbon offsets allows us to use the most effective combination of solutions. 


Carbon offsetting helps to fund projects that avoid further carbon being released into the atmosphere - such as renewable energy projects that replace fossil fuel sources, and peatland conservation that keeps carbon in the ground. They also help to reduce further emissions, such as through efficient cookstoves projects. 


Ecosystem-based projects, such as planting trees, help to capture carbon that is already in the atmosphere. While trees are not counted in offsetting until they have been growing for at least 10 years (as it takes time before they are big enough to capture large volumes of carbon dioxide), in that time they’re still doing their bit!

Why do we offset instead of just planting trees?

Yes! While offsetting is really important, it’s not the only solution to climate change. That’s why we’re also passionate supporters of projects that don’t provide credits, but do have a positive impact in other ways.  


We promote these local projects on our website and on the Club Leaf app so that the Club Leaf Community can learn more about them - and perhaps even help out in person! 

Do you support other projects than carbon offsetting projects?


With a Club Leaf membership, you can:  

  • Measure your footprint 

  • Reduce your emissions with our Green Tips and take part in our Green Challenges 

  • Offset 50%, 70% or 100% of your monthly carbon footprint by choosing to purchase Leaf points.  

And most importantly: support the very best accredited climate projects around the world

What do I get by being a Club Leaf member?

A Leaf point a fractional representation of a Voluntary Emission Credit (Carbon Credit). Each project we support issues carbon credits that are the equivalent of 1 ton of CO2e compensated. We turn these credits into 1000 Leaf points, so each Leaf represents 1 kg of CO2e compensated. As we fund different projects, each of which with a different carbon credit price point, our average Leaf point price is based on the average cost across projects.

What are Leaf points?

There are three ways in which you can collect Leaf points:  

  • You can purchase them.  

  • You can complete Green Tips and Green Challenges  

  • You can invite friends, colleagues and family  

How can I collect Leaf points?

Leaf points are directly converted to funding our selected environmental projects, and as such do not have an expiry date. When collecting Leaf points, all your points end up supporting great causes regardless of if you manage to reach your monthly goals. 


All this information is visible in your unique user overview in the app. After 12 months you can see whether you’ve reached your yearly target. 

For how long will I be able to use my Leaf points?

If you change your mind about purchasing Leaf, you have the right to withdraw from purchase within 14 days of the transaction. To do so, please send an email to

Wanna see how much impact have we made together for the planet? 







We want to have positive climate impact through what we do and how we operate. But we’re focused on more than climate action alone. Creating a better world is about working together, combining solutions, and taking action where it matters. It’s about halting biodiversity loss, improving livelihoods, and creating resilient food systems.

We treat our climate impact – the number of tons CO2e offset - as a primary measure of success. In addition, we’re committed to having environmental and social impact through our portfolio, our partners, and our own actions. Below are the key metrics we’ll be keeping track of to measure our impact.

Club Leaf

Impact Report 2021 -2022

When it comes to the future of our planet, we know it’s not that simple.



We’re committed to doing business in the most sustainable way. Whether that’s through the solutions we offer, the partners we decide to work with, or how we operate as a business. We’ve calculated our own greenhouse gas emissions. Just like you, we want to improve. We’ve set future targets and goals, and are working on our carbon footprint reductions as well as offsetting our carbon footprint through high impact climate projects.



 The climate crisis is global, and we want to make low impact lifestyles and carbon footprint reduction accessible across the globe. Our customer app is currently available in 7 countries: the Netherlands, Ireland, Germany, Austria, France, Belgium, and Luxembourg. On top of that, we’re also working with sustainable loyalty programs in 2 countries: the Netherlands and Brazil. 



Throughout this report we have tried to emphasise one cornerstone message, we’re in this together. Action is required by all of us, and we hope to combine forces so we can change the tides when it comes to climate action. We’re happy to have started this journey in 2021, and we’re now looking ahead to make an impact in 2023 we’re looking forward to creating more impact in 2023. 

Finalising this first impact report provides us with energy and excitement to help create a better planet for the future. Want to join us?
Get started today.



To be able to escape the climate crisis, it is important that we limit global warming to 1.5˚C. Our Green Tips are created to help our community live a more sustainable lifestyle and help them transition to becoming eco friendly, planet loving individuals. We are excited to welcome you to our community of action takers and see more people going green and moving towards carbon neutrality.



The graph below shows how many tons CO2e we have compensated for and retired since Q4 2021. We recognize that CO2e is one part of the sustainability transition but we know that we shouldn’t forget to pay attention to other important topics too. Therefore, we only compensated through climate projects that contribute to at least 3 UN Sustainable Development Goals (SDGs). Our goal is to compensate for a total of 1,000,000 tons CO2e in 2025 through these projects.
