The Green Product Analyzer provides data that are useful for assessing the sustainability footprint of chemical products, as well as for the selection of safer and more environmentally friendly products. The system has access to chemical profiles and substance data, which can be used to compare products by a variety of parameters, including toxicity, environmental impact, application, and cost. Users may set criteria to calculate ratings and to group products into categories, which can then be used to make direct and meaningful comparisons.
