As global warming reaches historical new highs, both corporates and individuals are increasingly looking towards concrete climate change solutions to reverse, or at least mitigate the severe damage that has already occurred.
Tree planting is the one of the worlds biggest and cheapest ways of absorbing CO2 from the atmosphere. During photosynthesis trees absorb and store carbon, later using it to build new materials such as trunks, stems and roots that facilitate their growth. CO2 removal through reforestation will help offset emissions from sectors like aviation where alternatives are not yet available.
However, the amount of carbon stored in trees depends on a number of factors, such as growth conditions in the environment, tree species, age of tree, and the density of surrounding trees. As such, it is relatively difficult to quantify the exact amount of carbon that can be sequestered. But trees are much more than ‘carbon sinks’.
A large majority of tree planting that occurs often takes place at a localised level. At such a small scale, trees offer a great deal of benefits to host communities, such as poverty reduction, food security, and economic empowerment. They are are valued for their localised function, by increasing resilience, promoting diversification, improving local economies and enhancing sustainability. Ultimately, the trees act as both a mitigation and adaptation strategy for climate change, which is vital if we are to reduce global emissions.
Another method of sustainable tree planting is Agroforestry - a land management system, where trees and crops are grown together. This unique land management practice can help relieve the pressure of overgrazed land, reduce erosion and increase biodiversity. It is also capable of improving water infiltration, thereby increasing soil fertility for agriculture and improving the microclimate.
That’s what we’re doing at Keystone. Using blended finance to fund live projects in Kenya, we’re planting trees that mitigate climate change and create the next generation of environmental stewards.
