A GHG (Greenhouse Gas) Inventory is like a detailed accounting system that measures how much greenhouse gas a company or organization produces. Think of it as a carbon footprint report card. It helps organizations track their environmental impact by measuring emissions from different sources like energy use, transportation, and industrial processes. Companies need this to meet environmental regulations, set climate goals, and show their commitment to sustainability. You might also see this called a "Carbon Inventory," "Emissions Inventory," or "Carbon Footprint Assessment."
