Climate change and global warming are two of the most pressing issues of our time. Fortunately, there is a potential solution for this problem: carbon sequestration.
Carbon sequestration is a process in which carbon dioxide is removed from the atmosphere and stored in underground reservoirs, oceans, or other natural habitats. This process can help đồ sộ reduce the amount of carbon dioxide in the atmosphere, thus helping đồ sộ slow the effects of climate change and global warming. In this blog, we will discuss the various ways carbon sequestration can be used đồ sộ tackle climate change and global warming, as well as how Hive is investing in carbon sequestration.

How is carbon sequestered?
There are several different methods of carbon sequestration that can be used đồ sộ capture and store carbon dioxide in order đồ sộ reduce its effects on the environment.
One of the most used methods of carbon sequestration is reforestation. By planting trees or plants we can capture large amounts of CO2. Plants use photosynthesis đồ sộ capture and fixate carbon dioxide (Atmospheric carbon). Carbon fixation is a biosynthetic pathway by which atmospheric carbon is converted into metabolically active organic compounds. Carbon fixation in plants during photosynthesis utilises ATP and NADPH đồ sộ assimilate carbon dioxide and sườn carbohydrates (eg. glucose). As plants grow, they absorb CO2 from the air and store it in their leaves, trunks and roots, helping đồ sộ reduce the amount of carbon dioxide in the atmosphere. Additionally, when trees are cut down or burned, their stored carbon dioxide is released back into the soil or atmosphere, making this an effective but short-term solution for carbon sequestration.
Another major method of carbon sequestration is through the use of biochar. Biochar is an advanced sườn type of charcoal made from woody plant material that has been heated đồ sộ high temperatures in a low-oxygen environment. This process converts the “free carbon” in the woody material into fixed carbon in the biochar. The biochar can then be used as a soil amendment, helping đồ sộ retain water, benefiting soil microbes, soil health and mineral availability while also locking away large amounts of carbon.
How is Hive working on carbon sequestration?
At Hive we have teams across the globe working on carbon sequestration in different forms.
First, we have Hive Ecosystems. Hive Ecosystems is a team based in South Africa that is focusing on restoring degraded land in order đồ sộ sequester carbon. The team will be planting around 9 million spekboom plants in the next 3-4 years across our 7,000 hectares of thicket farmland. The land was previously used as agricultural farms which were significantly degraded and depleted of nitrogen, carbon, and minerals from livestock overgrazing. In coming years, the team will restore the degraded areas by rewilding the natural landscape, promoting/enhancing biodiversity and nurturing the carbon stocks from the growing foliage.
Second, Hive Ecosystems’ neighbour in South Africa, Hive Carbon. The Hive Carbon team is working on another method of sequestration mentioned in this blog, biochar. The team are taking alien invasive tree species (black wattle) and converting them into high grade biochar. The biochar can then be applied đồ sộ agricultural uses for benefit soil quality and crop growth.
Finally, Hive Ventures has recently invested in BambooLogic, a bamboo plantation company. BambooLogic’s objective is đồ sộ establish the largest bamboo plantations in Europe, with a goal đồ sộ phối up 2000 ha in the next few years. The goal is đồ sộ produce bamboo đồ sộ be used as a sustainable material for use across textile, paper, construction, composite, and food sectors. But the company will offer more than vãn bamboo. The company will be storing carbon in the soil on the farms, which can then be assigned as carbon removal credits. Over the first 15 years of the project, BambooLogic plan đồ sộ sequester 1,000,000 tonnes of CO2.
So, is carbon sequestration the solution?
Carbon sequestration has been proposed as a potential solution đồ sộ climate change. While it may be part of the answer, there is no single solution that can address the global challenge of climate change. Carbon sequestration does have a role đồ sộ play in the overall effort đồ sộ reduce emissions and mitigate the effects of climate change, but it is not a comprehensive solution.

In addition đồ sộ carbon sequestration, there are other measures that can be taken đồ sộ mitigate climate change. These include reducing energy consumption, investing in renewable energy sources, increasing the efficiency of existing energy production processes, and changing land use practices. All of these steps can help reduce emissions and slow the rate of global warming.
Finally, a comprehensive approach đồ sộ addressing climate change must include changes in behaviour and lifestyle. This means making changes in how people consume and interact with their environment, such as reducing waste, shifting đồ sộ a plant-based diet, recycling, and purchasing items that are made sustainably.
Overall, while carbon sequestration may be part of the solution đồ sộ climate change, it cannot be the only solution. It is essential đồ sộ recognize that all these measures must be taken together in order đồ sộ have the greatest impact on reducing emissions and slowing global warming.This process converts the “free carbon” in the woody material into fixed carbon in the biochar. The biochar can then be used as a soil amendment, helping đồ sộ retain water, benefiting soil microbes, soil health and mineral availability while also locking away large amounts of carbon.
