Not only are they seeing public campaigns in support of their mission, they are seeing critical financial support, as well. Most recently, Shopify, through its Sustainability Fund, is purchasing carbon removals through Puro.earth from three biochar providers: Carbofex, ECHO2 and Ecoera. These companies manufacture a kind of glorified charcoal called biochar, which is made by heating wood scraps to high temperatures without oxygen via pyrolysis – thus creating a charred, charcoal-like product that can be mixed with soil to improve its quality. It can also be used as an animal feed additive or filtration substrate. In theory, biochar represents a net carbon sink because it sequesters the carbon inside the wood chips, preventing it from turning to carbon dioxide and contributing to global warming. With Shopify's purchase, for instance, these biochar producers are able to remove obstacles to production and scale more quickly.
