What it means
Sustainability means assuring the long-term survival of our planet by conserving and caring for its resources rather than depleting or permanently damaging them. Our growing awareness of the effects of climate change and deforestation makes sustainability and environmental stewardship everyone’s concern today.
Why it matters
For companies, sustainability and profitability go hand-in-hand. A commitment to environmental sustainability makes for good corporate citizenship, which improves a company’s relationship with customers, investors, regulators, neighbors and suppliers. The alternative to environmental sustainability is no longer tolerable. Sustainability is not only good for the earth and its people; it’s increasingly connected to building bottom lines and improving shareholder value.
