Sustainable design decisions are decisions that consider the sociotechnical impact of the alternatives. After designing and analysing the alternatives, you pick the one that gives you the best sociotechnical trade-​ off with the information that is available. You create a feedback loop into your design process to improve it along the way. Over time, you will find yourself making decisions in a similar way. This is when your decisions become sustainable.
