Frequently asked Questions

Carbon Removal Vocabulary

What is Climate Change?

Climate change traditionally refers to the constant, natural fluctuations in Earth’s climate, however recently has become the common term for the man-made, rapid changes happening since the Industrial Revolution. Other names include ‘global warming’, ‘the climate crisis’ and ‘the climate emergency’. Due to human activities - like burning fossil fuels - an excess of greenhouse gases accumulated in the air over time trapping heat in the atmosphere resulting in an overall warming effect. This increasing average temperature provokes severe changes in the climate as we know it.

What is the Greenhouse Effect?

The greenhouse effect is a natural phenomena in which the greenhouse gases in the atmosphere trap heat leading to an increased temperature. As mankind is increasing the amount of greenhouse gases in air, the greenhouse effect is intensified resulting in an unnatural, rapid rise in temperature changing the climate as we know it - anthropogenic (man-made) climate change.

What is a Carbon Footprint?

A carbon footprint refers to the total amount of carbon dioxide produced by a person, organization, or activity during a given period of time. The carbon footprint can also consider other greenhouse gases produced, such as methane, nitrous oxide, and chlorofluorocarbons. It’s a useful measurement to monitor how much carbon dioxide and other greenhouse gas emissions are produced to be aware of the impact on the climate and as a help to minimise it. The unit used is tons or kilograms of CO₂ or CO₂-equivalent gases emitted per time unit.

What is Carbon Offsetting?

Carbon offsetting is the action of reducing, avoiding or sequestering a unit of carbon dioxide or other greenhouse gases to compensate for emissions occurring somewhere else. Carbon offsetting is frequently done by purchasing carbon credits, but it can also be done by funding practices that actively remove carbon dioxide from the atmosphere. Carbon offset schemes allow companies and individuals to compensate for their carbon footprint, it’s a way to balance out their emissions or reduce the damage caused by a specific activity, such as traveling by plane.

What are Carbon Credits?

Carbon credits are a currency for trading carbon emissions in the carbon market. A carbon credit represents the right of an entity to release one ton of carbon dioxide or the equivalent amount of other greenhouse gases into the atmosphere. However, carbon credits have some limitations since the entity would be paying someone else to prevent a negative impact instead of actually removing the produced carbon dioxide from the atmosphere. For example, if an entity emits two thousand tonnes of CO₂, it can purchase carbon credits to ensure that another entity reduces two thousand tonnes of CO₂ from its own emissions.

What is Carbon Neutrality?

Carbon neutrality or being carbon neutral is achieved if the amount of CO₂ emissions produced is equal the amount of CO₂ emissions removed from the atmosphere or reduced somewhere else. For example, if a company produces two thousand tons of CO₂ and purchases carbon credits to compensate for the exact amount of CO₂ produced or funds other carbon offset schemes to actively remove two thousand tons of CO₂ from the atmosphere, then it is considered to be carbon neutral.

What is Carbon Sequestration?

Carbon sequestration is the action of removing carbon from the atmosphere and depositing it in other carbon sinks, such as forests, the ocean or underground. These reservoirs store carbon dioxide for a long time and prevent it from entering the Earth’s atmosphere. For instance, forest regrowth is a form of carbon sequestration. Trees will remove carbon dioxide from the atmosphere through photosynthesis and use it to build wood, leaves, and roots. Therefore, they store carbon for a long time.

What is Carbon Removal?

Carbon removal, carbon dioxide removal or CDR, refers to a group of anthropogenic activities that actively remove and sequester carbon dioxide from the atmosphere. Carbon removal uses natural-based, technology-based, and combined natural/technology-based practices to create negative emissions. Even though carbon removal is essential to remove greenhouse gases already in the atmosphere, it isn’t a substitute for reducing carbon dioxide emissions and deforestation. Carbon removal practices and technologies include afforestation, carbon farming, direct air capture and storage, enhanced weathering, and others.

What are Negative Emissions?

Negative emissions are the opposite of released greenhouse gases. Negative emissions refer to the deliberate removal of carbon dioxide from the atmosphere via carbon removal practices and technologies. For some greenhouse gas-emitting activities like aviation, it’s impossible to get their emissions down to zero. Therefore, the best alternative for some entities is to combine reduction efforts with negative emissions to balance out their emissions.

What is net-zero?

Net-zero means that anthropogenic emissions are balanced by removing an equivalent amount of carbon dioxide from the atmosphere over a specified period. Unlike carbon neutrality, entities can only achieve net-zero via carbon removal practices and technologies. However, to get to net-zero, it’s also important to dramatically reduce greenhouse gas emissions by replacing greenhouse gas-emitting technologies with clean ones. With this approach, the remaining greenhouse gas emissions could be balanced with carbon removal options to reach net-zero.

What is Climate Positive?

Climate positive or carbon negative means that an entity or activity removes more carbon dioxide from the atmosphere than it emits. In other words, it produces a positive impact that counteracts climate change. To become climate positive, an entity shouldn’t rely on carbon offsets to delay reductions of its emissions. Carbon offsets should only be used in addition to other reduction efforts to reach the climate positive goal. For example, if a company produces two thousand tons of CO₂e per year but removes three thousand tons of CO₂e per year, it’s climate positive.

Carbon Removed

Where does my money go?

A minimum of 70% of your money goes directly to our removal projects to make sure your carbon footprint is removed quickly, sustainably and permanently.

The remaining money (up to 30%) is used for everything else. We need to spread the word, run our business and create new features.

We also publish a more detailed breakdown on our transparency page.

Where do I find proof?

We make all of the invoices and certificates we receive from our partners available on our public ledger so you can see that we are removing your carbon footprint.

How is my carbon footprint removed?

Currently 98% of your emissions will removed by trees sequestering CO₂ and 2% by direct air capture and storage of CO₂. Find more details about our removal projects and what we have achieved so far.

After creating a subscription or purchasing a custom removal amount we will plant and maintain enough trees to make sure your chosen amount is compensated. Furthermore, we will routinely turn enough CO₂ into stone with direct air capture and storage. All transactions with our partners are publicly available as proof of this statement. You will receive a certificate of removal from us as verification that you are compensating parts of your footprint.

Learn more about the technicalities about how CO₂ is removed from our air sustainably and permanently.

How do you guarantee the carbon removal?

Our primary focus is to reverse climate change through guaranteed, permanent and sustainable carbon dioxide removal and this is reflected in the methods and partners we choose to do so.

To compensate your carbon footprint, we only support carbon dioxide removal and not carbon credits, which are ambiguous and not guaranteed. At the moment we support tree planting and direct air capture and storage.

The method direct air capture and storage has by nature a solid guarantee as it is constantly capturing and removing CO₂ from the atmosphere, turning it into stone which will remain solid and unchanged for thousands of years.

Trees are also an excellent natural carbon sink provided they do not rot and are not burned as this will release the CO₂ back into the atmosphere. When selecting tree planting partners we will only choose those which can guarantee that the trees will be properly maintained and under no circumstances be cut down for at least 30 years (realistically the trees will stand much longer than this).

Sadly natural disasters such as wildfires do happen and we cannot guarantee against these occurrences. Where possible we do contribute and maintain existing forests as well as supporting the replanting of destroyed lands.

The partners we choose who help us plant the trees or use their ‘direct air capture and storage’ machines are selected extremely careful. Learn more details about the carbon removal projects we support under this link.

What happens if I cancel my subscription?

All CO₂ removed in your name will stay captured and removed from the atmosphere.

Cancelling your subscription is possible any time. Simply send a message to and we will stop removing CO₂ for you.

Don’t worry though - all CO₂ currently removed will stay that way - captured in your name and the certificates of proof are yours to keep.

All trees planted will remain standing with future maintenance covered by our pool of active subscribers and future sequestration allocated to fresh subscribers if possible. If not the trees will be a gift from us to the planet.

What differentiates you from other companies in this space?

Removal, not Reduction.

This subtle yet important point is our key selling point and differentiator.

Our existing carbon dioxide levels in the atmosphere are a lot higher than they should be and this will require some work to bring down again.

Other companies focus on reduction of future emissions (carbon credits) but we know that unless the existing excess is tackled, we will not make it to the future to begin with.

Carbon Removal versus Carbon Credits?

“Carbon credits” are certificates that are created and sold by projects that aim to reduce future emissions. While these projects may have a great social impact they do nothing to combat previous emissions and the existing excess of carbon dioxide in the atmosphere. For example, providing “green coal” to communities in Africa may help those people produce less carbon dioxide however emissions are still being released. The difference in CO₂ between these “reduced” emissions and the original emissions is what makes up a carbon credit and this is sold as offsets to people and businesses.

“Carbon removal” on the other hand actively extracts and permanently removes carbon dioxide from the atmosphere. Compensating footprints in this way is essential to undo the existing excess of carbon emissions and to fight the climate crisis.

Why are you so expensive?

Science - once the carbon dioxide is in the atmosphere it’s a lot harder to remove again. We have an excess already and this must be removed (as well as emissions rates reduced) to ensure our survival.

We also support a variety of technologies of varying costs to make sure that as much progress as possible is made in this area.

As we grow our buying power will increase and prices will drop - your support today will help us get cheaper in the future.

Climate Change

Why does the climate change?

The ice age cycles from the last 3 million years were caused by periodic oscillations of Earth’s rotation and orbit, which lead to changes in the distribution of sun light.

Earth’s rotations and distance to the sun are not the only factors determining the climate, Earth’s atmosphere has a profound impact on the climate as well.

Learn more about the causes of climate change.

Is the climate changing?

In Earth’s history the climate has always varied and thanks to modern science we are able to calculate how it has changed in the last few million years. There were mild periods like the one we are in at the moment, but also states in which giant ice sheets covered the northern continents.
