Sustainability marketing is important for several key reasons: 1) It is morally responsible and meets growing market and customer expectations for environmentally-friendly practices. 2) Embracing sustainability can improve a business's bottom line performance over time as consumers increasingly favor brands they perceive as sustainable. 3) Successful sustainability marketing requires businesses to authentically adopt and demonstrate sustainable practices throughout their operations, not just "sell" the idea of sustainability. 4) Marketers should position sustainable products and services as delivering quality and performance first, with environmental benefits as an additional value.
