What is Sustainable Development? • A standard definition • “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” – Bruntland • A mining & metals definition • “ensuring that our businesses create a valuable legacy rather than leave a costly liability behind” • building capacity for diversified economic activity • education and skills development • better public health • environmental protection • What does it mean to us ?

4. What does it mean to us? What if people don’t believe our business behaviour is consistent with that? • Will they want to work for us? • Will they want us as their neighbours? • Will they want to buy our products? • Will they want to invest in our business? • Will they trust us to care for their environment and resources? • Will they elect people that will support us? What are the implications of being unsustainable for our business?
