Welcome to the beginner’s guide to environmental footprinting! If you’re new to measuring environmental impacts, this section will help you understand the key concepts, terminology, and processes involved in assessing a product’s environmental footprint.

​
What is Environmental Footprinting?

Environmental footprinting is the process of measuring the environmental impacts associated with a product, service, organization, or activity throughout its life cycle. It helps identify where environmental impacts occur and provides insights for improvement.
Think of an environmental footprint as a way to measure the “environmental cost” of making, using, and disposing of a product—similar to how a financial budget tracks monetary costs.

​
Why Measure Environmental Footprints?

Organizations measure environmental footprints for several important reasons:

Identify Improvement Areas

Discover which materials, processes, or life cycle stages have the highest environmental impact, creating opportunities for targeted improvements.

Make Informed Decisions

Compare different design options, materials, or suppliers based on their environmental performance.

Meet Stakeholder Expectations

Respond to growing demands from customers, investors, and regulators for environmental transparency and responsibility.

Track Progress Over Time

Establish baselines and monitor improvements in environmental performance as changes are implemented.

Environmental Footprinting Basics

​
The Product Life Cycle

Environmental footprinting considers impacts across the entire life cycle of a product:
1

Raw Material Extraction

Mining, harvesting, or collecting the raw materials needed to make the product.
2

Material Processing

Converting raw materials into usable forms (e.g., turning bauxite into aluminum).
3

Manufacturing

Assembling materials and components into the final product.
4

Distribution

Transporting the product from factory to retailer to consumer.
5

Use Phase

The period when the consumer is using the product.
6

End-of-Life

What happens when the product is no longer used (disposal, recycling, etc.).

​
Types of Environmental Impacts

Environmental footprinting measures multiple types of impacts, not just carbon emissions. GREENZERO Journey tracks eight key environmental impact categories:
Measures how much a product contributes to global warming through greenhouse gas emissions. Example: The carbon dioxide released when burning fossil fuels to power manufacturing equipment. Measured in: kg CO₂ equivalent
Measures emissions that can cause acid rain, which damages ecosystems, buildings, and water bodies. Example: Sulfur dioxide released from burning coal or oil. Measured in: kg SO₂ equivalent
Measures nutrients released to freshwater that cause excessive algae growth, depleting oxygen and harming aquatic life. Example: Phosphorus from fertilizers washing into lakes and rivers. Measured in: kg P equivalent
Similar to freshwater eutrophication but specifically for marine environments. Example: Nitrogen from agricultural runoff reaching oceans. Measured in: kg N equivalent
Measures emissions that can form ground-level ozone and smog, causing respiratory problems. Example: Nitrogen oxides from vehicle exhaust. Measured in: kg NOx equivalent
Measures substances that damage the Earth’s protective ozone layer. Example: Certain refrigerants and aerosol propellants. Measured in: kg CFC-11 equivalent
Measures the volume of freshwater consumed throughout the product life cycle. Example: Water used in manufacturing processes or growing agricultural products. Measured in: m³ (cubic meters)
Measures the amount of land transformed or occupied for a product’s life cycle. Example: Forest cleared for agriculture or mining. Measured in: m² yr (square meter years)
