Sustainability is a societal goal that relates to the ability of people to safely co-exist on Earth over a long time. Specific definitions of sustainability are difficult to agree on and have varied with literature, context, and time. The principles of sustainability are the foundations of what this concept represents. Therefore, sustainability is made up of three pillars: the economy, society, and the environment. These principles are also informally used as profit, people and planet. How can we achieve green economy? Achieving radical – and not just incremental – sustainable technological change. Incremental innovations, e.g., increased material and energy efficiency in existing production processes, are key elements for the transition to a green economy.
