Fact #3 – Use of Mass Balance
BCI uses a chain of custody model called Mass Balance, which encourages supply chain actors to buy and use more Better Cotton in a cost efficient manner, as it does not require complexities that result in costly physical segregation along the supply chain. Mass Balance functions much like renewable energy. If you purchase renewable energy credits, a power line is not run, from say, a wind farm directly to your house. Rather, the credits are proof that a certain amount of renewable energy has been added to the existing power grid. This energy might not be powering the lights in your house, but nonetheless, your purchase ensures that greener energy is added to and pulled from the power grid. In this way, by committing to sourcing Better Cotton, brand members can be assured that they are supporting more sustainable cotton production regardless of where that cotton ends up.
