Think about material, operation, energy, business model, retirement, … 2. Determine how to quantify† the impact of each. 3. Try to quantify the financial aspect of each. Consider the cost of development, goods, production, use. † Define a metric, even if you cannot give a number right now. After 10 min, I will ask for some examples. dr. ir. G.A.
