The triple bottom line (TBL) framework evaluates a company's performance across three dimensions of social, environmental and financial sustainability. It was first coined by John Elkington in 1998 to describe a business's accountability to its stakeholders, including people, planet and profit. A TBL company considers the well-being of its employees, reduces its environmental impact through sustainable practices, and creates real economic value for the community rather than just profits for shareholders. All three pillars are interdependent, and a truly sustainable business model avoids harmful products and accounts for full life cycle costs and disposal to minimize its ecological footprint.
