What is meant by ‘Design for Sustainability’?

“Like any good design, sustainable design involves delivering the best performance or result for the least cost over the long term. Sustainable design involves the strategic use of design to meet current and future human needs without compromising the environment. It includes (re)design of products, processes, services or systems to tackle imbalances or trade-offs between the demands of society, the environment and the economy and, ultimately, restoration of damage already done.”
