How do I become an UNDO customer as a company?
It’s very simple! You can download our mobile app to do it or via our website by selecting the subscription of your choice.
1. You must first log in with ITSME to create your account.
2. Then follow the order steps until it is finalized.
3. You will receive an email confirmation of your order.
4. Afterwards, send us an email to “support@undo.be” with the contact details of your company: Company name, last + first name of the legal representative, company address and VAT number. We will do the necessary to change your private account into a business account.If you order an eSIM, you will receive a second email with the QR code of your eSIM in order to install it on your smartphone. The activation of your number with an eSIM is generally active within the hour and you can start using it immediately, unless you have made a request for a number transfer. In that case, the delay mainly depends on your current operator!

What is “UNDO Forest”?
UNDO Forest is a project that aims to create a natural carbon sink that will absorb and store carbon below the ground in soil. It’s 100% owned by UNDO. The project is being developed in the Democratic Republic of CONGO, near the town of Kinshasa. We work in collaboration with our partner IBI Village, which helps us with on-ground activities. The project aims to plant 25.000 trees in its 1st phase. The concept of agroforestry is applied that ensure maximum utilization of the land and turn a dry savannah into a habitat filled with acacia, corn, and manioc. Every new subscription guarantees planting 1 tree but that is not it. Under the project, our members can also support additional social initiatives by adding “UNDO Forest” add-ons to their monthly subscription. This way our community not only helps the planet but also helps out the local population by providing employment, and aid, much like the UN sustainable goals.
UNDO provides regular updates about the progress of the project and on ground activities via photos, videos, or even interviews of locals via our social media channels. Follow UNDO on Facebook, Instagram, Tiktok to stay updated.

What is “UNDO Removal”?
UNDO Removal connects the UNDO community to carbon removal technologies. These technologies remove carbon from the atmosphere and store it long-term, for over 100 years, in different forms such as demolished concrete or underground sequestration. One of the biggest challenges for such technology-driven projects is the high cost of execution, which can be lowered through economies of scale. UNDO procures high-quality, certified removal credits from individual project developers across the globe. Projects are verified by independent third-party agencies and follow internationally recognised standards such as Gold Standard, Puro.earth and Verra. UNDO Removal lets members direct their monthly CO₂ credits to certified, verified carbon removal projects of their choice. You can use the CO₂ KGs already included in your monthly subscription at no extra cost.
-
What can I do with my CO₂ KGs?
As an UNDO member, you have the chance to contribute to the fight against climate change. Planting trees is surely one of the simplest ways of helping and having a direct impact. That is why each new member joining UNDO plants one tree by default in our UNDO Forest – a natural carbon sink. But that is not all, every UNDO member can also support emerging carbon removal technologies such as biochar, CCS, and enhanced weathering via “UNDO Removal”. The CO₂ KGs included in your subscription can be assigned to one or more removal projects of your choice — and our app shows you the emissions of your monthly mobile use alongside them, so you can see what you are supporting.
