ABSTRACT
The three pillars of sustainability framework is a multidisciplinary implementation and solutions oriented approach that recognizes most successful and scalable sustainability solutions require the presence of, and are driven by, all three pillars simultaneously: 1) technology and innovation; 2) laws and governance; and 3) economics and financial incentives. The three pillars framework is strategic because it often reveals or describes specific and feasible changes that advance sustainability solutions within markets and institutional settings. The section on technology discusses the crucial role that technology plays in creating new ways for doing more in our rapidly urbanizing communities by using less resources and energy inputs. The section on economics discusses problems with current conceptions of economic welfare that measure growth (flow) rather than the asset base (wealth), and explores possibilities for integrated and multidisciplinary analysis for coupled economic and social systems. The section on laws and governance considers the role of legal frameworks related to incentives, regulatory baselines, and in public policy formation, including influences and feedback effects from social norms, changing culture, and sustainability education. Technological development and engaging economic markets are at the center of our best and most rapidly deployable sustainability solutions. In that context, a specific focus is given throughout the discussion sections to the key role of laws and governance in supporting relevant, effective, and sustainable technological and economic development, as well as to highlight the crucial (often final) steps the law plays in successfully implementing new sustainability projects. As the discussions and examples (taken from Asia, the US, and Europe) demonstrate, the three pillars framework is flexible and useful in a number of contexts, as a solutions template, as an integrated planning approach, as a decision making guide, and for determining project priorities.
