This chapter explores the Solid Works Sustainability tools to analyze the environmental impact of a design throughout the life cycle of a product. Solid Works Sustainability evaluates the environmental impact of a design throughout the life cycle of a product. The engineer or designer can compare results from different designs to ensure a sustainable solution for the product and the environment. Sustainability measures the following areas of environmental impact: carbon footprint, energy consumption, air acidification and water eutrophication. Solid Works measures the environmental impact based on the following parameters: materials used, manufacturing process and region, transportation and use region and end of life disposal. The Environmental Impact dashboard at the bottom of the Task Pane provides real-time feedback about the environmental impact of the engineer's or designer's design.
