The ERG gives architects and others in the building industry a basis for comparing the environmental impact of building materials, products and systems. It provides a consistent format for assessing the environmental impacts of building materials from their original extraction and manufacture to their final disposal or reuse. The ERG was launched by the AIA in 1992 with funding from the EPA to create a simplified methodology for assessing the environmental impact of building materials, and as a vehicle for disseminating that information to the building community at large. The AIA Press has brought in Wiley as a publishing partner to improve its content, format, packaging and marketing.

This book provides a systematic review of those economic approaches for valuing the environment and natural resources that use information on what people do, not what they say. The authors have worked on models of revealed preferences for valuing environmental and natural resources for several decades. The book provides a candid review of the major conceptual challenges and an exploration of neglected issues in the literature.

During the Civil War, humans impacted plants and animals on an unprecedented scale as soldiers on both sides waged the most environmentally destructive war ever on American soil. In Flora and Fauna of the Civil War, Kelby Ouchley blends traditional and natural history to create a unique text that explores both the impact of the Civil War on the surrounding environment and the reciprocal influence of plants and animals on the war effort. After discussing the physical setting of the war and exploring humans' attitudes toward nature during the Civil War period, Ouchley presents the flora and fauna by individual species or closely related group in the words of the participants themselves. Collectively, no better sources exist to reveal human attitudes toward the environment in the Civil War era.
