Comprehensive understanding of the environmental and resource implications for humanity’s economic activity involves thinking in terms of the full life cycles of our goods and services. Thanks in large part to the work of William McDonough and Michael Braungart, awareness of “cradle to cradle” design thinking has spread beyond the worlds of industrial ecology and ecological economics to establish a toehold in popular sustainability-oriented discourse. Over the past decade or so, it has started to dawn on an increasing number of us that the things we consume on a daily basis are connected to a globe-spanning network of socio-ecological consequences the extent of which is belied by the apparently modest materiality of our “stuff”. It’s in the context of this awakening systemic insight that the concept of embodied energy has—at least amongst those of us with an interest in the relationships between the spheres of technology, society and environment—come to be meaningful. Here in Australia, particular effort has been directed towards making information about the embodied energy of housing construction materials widely available—and moreover, to making this understandable for people involved in making the decisions that this might inform.
