Background: Corporate Social Investment (CSI) is a self-regulating business model that helps a company be socially accountable to itself, its stakeholders, and the public. By practising CSI, companies can be conscious of the kind of impact they are having on all aspects of society, including economic, social, and environmental. To engage in CSI means that, in the ordinary course of business, a company is operating in ways that enhance society and the environment instead of contributing negatively to them.
