Carl Stein's New Book, Greening Modernism: Preservation, Sustainability, and the Modern Movement, raises discussion about the connection between sustainable practices and modern architecture. Through addressing the environmental impacts of building decisions, the author argues the inherent sustainability in Modernist design. Focusing upon the importance of preserving and reusing historical buildings as a key sustainability strategy, Greening Modernism serves as a resource for architects, engineers, urban planners, as well as environmentalists. To support his case, Stein provides quantitative data to support the reintegration of modernist strategies, through reducing our dependency on finite resources, such as petroleum. The book rings clear with the sentiment that through understanding the environmental importance of their decisions, architects can continue their practice while doing their part to save the planet.
