**Project Activity**\n  \n**Underground Forest** combines Carbon Dioxide Removal (CDR) with the structural reinforcement of water-saturated peat or clay soil.   \nTo build real estate and infrastructure on soft grounds like peat or clay, we need a foundation. Currently, almost all of these foundations are built using concrete piles. Our main activity is working with key players in the Netherlands to help them switch back to how we used to do it in the past, using wooden piles inserted deep in the ground below the groundwater level.  \nInstead of emitting large amounts of CO₂ with concrete foundations, we can build that same **foundation using wooden piles and remove large amounts of CO₂ simultaneously**.  \n\n# **Why is it important?**\n   \nGlobally, the construction sector is responsible for about 37 to 39% of all CO₂ emissions. Concrete is responsible for roughly a fifth of these emissions, meaning our Underground Forest can make a significant impact. **Underground Forest tackles two critical challenges simultaneously:** \n1. Urgent climate mandate to physically remove carbon from the atmosphere;\n2. Massive housing construction task in the Netherlands (and Europe) on soft peat and clay soils.\nOur focus location is, at first, the Netherlands, as a large part of this country is made of peatland.  \n\n# **Why does it need funding?**\n \n- The main challenge is that **building with concrete piles is cheaper** than building with wooden piles. We need to overcome this price gap by using part of the carbon credit revenue to eliminate this argument;\n- In order to scale the project, we will take the developed methodology to other countries where there is peatland (like Germany, the United Kingdom, Finland, Malaysia, Indonesia, and Canada). In these countries, building on soft ground is also done using lots of concrete, and we need to build an organization that can help them transform as well.\n \n# **What makes it unique?**\n   \nThe Underground Forest is distinguished by its **dual-purpose methodology, unprecedented storage density, and reliable permanenc**e:\n- **Dual-use:** It uniquely serves two societal goals at once by functioning as a high-volume carbon sink while acting as a structural foundation for real estate and infrastructure developments.\n- **Simple solution to a complex problem:** It’s likely that we keep on building for a while. If we continue on the same path, using concrete or even low-CO₂ concrete, the construction sector will remain a climate liability. With this simple and effective solution, we can overcome that challenge below ground.\n- **Storage Density:** Because of the high density of the underground piles, a combined approach can store 20 times more CO2 per hectare than a regular above-ground forest.\n- **Unmatched Permanence:** The project scores the highest on protection against threats that typically endanger CDR projects. Because the piles are stored beneath the groundwater table in an anoxic environment, they are fully protected from decay. Even in worst-case climate scenarios, such as the flooding of the Dutch polders due to sea-level rise or human neglect, the wood will remain submerged, serving as the ultimate insurance against carbon re-emission. And the Underground Forest is fully insensitive to earthquakes, pests, and fires.\n- **Exact and Simple MRV:** Our carbon accounting is exact, as the volume, diameter, and length of every single pile are known and verified via invoices and the Pile Plan, which we have for each building. Every pile's location is mapped via GPS. Long-term monitoring is reliable because the Dutch Waterboards publicly monitor and decree the exact groundwater levels regularly, ensuring the pile tops remain safely submerged without the need for proprietary sensors.\n"}}
