Forests - whether tropical jungles, broadleaf or coastal mangroves - are one of nature's wonders, making life on this planet possible through their absorption of carbon dioxide and release of oxygen. They also provide shelter and nutrients to countless species in their ecosystems, supporting the planet's biodiversity.
Mangroves are one of the species with the greatest potential to remove carbon. They grow rapidly and reach maturity quicker than many others, increasing the immediacy of their positive impact on the environment. They also can have considerably higher CO2 absorption levels than terrestrial trees, with one study (Fatoyinbo et al, 2017) finding Mangroves sequester carbon at 2 to 4 times the rate of other species in their biomass and in the soil. This is why Climate Responsible is focusing on supporting Mangrove projects for our forestation solutions.
Over a 25 year growth life, our Mangrove partner - Eden Projects - has demonstrated that each tree absorbs on average 308kg of CO2. Allowing for a 50% buffer to mitigate the risk of any losses to storms, pest or other decay, we purchase five Mangrove sapling plantings for every tonne of CO2 to be removed.
Because of the positive impact that Mangroves have on their ecosystem and the biodiversity they support, Climate Responsible will plant an additional Mangrove sapling for every one that is purchased as part of one of our products, doubling the positive impact of your removal.
All trees - whether they are Mangroves or otherwise - absorb CO2 as they grow and store this in their biomass predominately during this growth phase. Once mature - after around 20 years for most species - the net absorption slows, and flows of CO2 during the tree's respiration are approximately balanced for the remainder of its life.
Trees are considered a temporary carbon store due to their natural lifecycle as well as their vulnerability to pests, fire and other decay. Once a tree dies, it will slowly release its CO2 back into the atmosphere, with part of the CO2 being incorporated into the soil and remaining trapped beyond the tree's lifespan.
Put simply, trees provide an essential interim solution to removing carbon over the next few decades. This buys us essential time to reduce emissions and develop the technologies that will enable massive-scale carbon removal.
