Industrial Ecology Metrics aim to quantify and assess the environmental impacts of industrial activities, including resource consumption, waste generation, and pollution emissions.

Material Flow Analysis, Life Cycle Assessment, and Environmental Impact Assessment are all widely used Industrial Ecology Metrics for evaluating the environmental performance of industrial systems.

Material Flow Analysis focuses on tracking and quantifying the movement of materials through an industrial system, including raw materials, intermediate products, and waste.

Life Cycle Assessment takes a comprehensive approach, considering all stages of a product or service's life cycle, from raw material extraction to end-of-life disposal.

Environmental Impact Assessment aims to identify and assess the potential environmental consequences of a proposed project before it is implemented.

Energy Intensity measures the amount of energy consumed per unit of output or production.

Carbon Footprint quantifies the total amount of greenhouse gases (such as carbon dioxide, methane, and nitrous oxide) released into the atmosphere as a result of an activity.

Water Footprint considers the total volume of water used or polluted throughout the life cycle of a product or service, including water consumption, water pollution, and water scarcity.

Ecological Footprint calculates the total area of land and water required to sustain a population, considering factors such as food production, housing, energy consumption, and waste disposal.

Supply Chain Sustainability Assessment focuses on evaluating the environmental, social, and economic impacts of a supply chain, considering factors such as resource use, emissions, labor practices, and community well-being.

Industrial Symbiosis aims to create a network of industries where the waste or by-products of one industry become the raw materials for another, promoting resource efficiency and reducing environmental impacts.

Material Intensity measures the amount of material required to produce a unit of a product or service.

Embodied Energy quantifies the total amount of energy consumed throughout the life cycle of a product or service, from raw material extraction to end-of-life disposal.

Embodied Carbon calculates the total amount of greenhouse gases (such as carbon dioxide, methane, and nitrous oxide) emitted during the life cycle of a product or service.

Water Footprint considers the total volume of water used or polluted throughout the life cycle of a product or service, including water consumption, water pollution, and water scarcity.
