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.
