The document discusses environmental product declarations (EPDs), which provide metrics on the environmental impacts of products over their lifecycle including raw material extraction, transportation, manufacturing, use, and waste processing. An EPD includes data on emissions to air and water, energy and resource usage, waste generation, and impact categories such as global warming potential, acidification, and ecotoxicity. The document presents an EPD for CEM I cement, listing metrics for impacts including greenhouse gas emissions, ozone depletion, acidification, ecotoxicity, human toxicity, summer smog formation, energy usage, resource depletion, and solid waste.
