What is UNDO Removal?
UNDO Removal aims at connecting the UNDO community to literally carbon removal technologies! In an attempt to balance the amount of carbon released due to human activity, these technologies ensure the removal of atmospheric carbon and long-term storage for over 100 years in different forms such as demolished concrete, or underground sequestration! One of the most critical challenges of the present day faced by such technology-driven projects is the high cost of project execution, which can be lowered by applying the principle of economies of scale. UNDO procures high-quality, certified REMOVAL credits from individual project developers across the globe. Projects are verified by independent 3rd party agencies and follow internationally recognized benchmarks and reporting standards such as Gold standard, Puro earth, and Verra. For users, UNDO removal is a way to choose projects of their choice and be carbon-neutral by compensating their emissions every month. You can use your CO2 KGs pre-included in your monthy subscription

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 agro farming 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, users can also support additional social initiatives by adding UNDO forest add-ons to their monthly subscriptions. This way the 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.

You can find these KGs and projects in UNDO removal section Just log in to the application, assign KGs to the project you like and hit Compensate! This represents your support for the choice of projects and helps in connecting users directly to Projects at the tap of a screen.
In case your emissions are higher than the available KGs you can purchase extra KGs. You can find these add-ons by tapping on ‘SHOW ME’ in ‘Your Tariff’ section via the mobile app or web. Your KGs that remain after compensation will be carried over and added to your available quota next month.
