Welcome 👋

Ready to understand how products impact the climate? By the end of lesson four, you’ll know: What a product carbon footprint tells you about a product’s climate impact The key data sources included with a PCF The different scopes of PCF measurements and when to use them

What is a Product Carbon Footprint?

A Product Carbon Footprint (PCF) shows you part of a product’s environmental impact. It tracks all the greenhouse gas emissions created throughout a product’s life. From the moment you gather raw materials until the product reaches its last destination — whether that’s in landfill or the recycling bin.

More specifically, a PCF includes emissions from key data sources such as:

• Raw material extraction and processing
• Manufacturing
• Transport, storage, and distribution
• Product use
• Disposal / end-of-life management

Important: Manufacturing often represents only a small portion of total emissions. Most emissions occur either:

• Upstream (through activities like mining raw materials or farming ingredients)
• Downstream (through product use and disposal)

You’ve probably come across PCFs without even knowing it. For example, the EU’s Ecolabel promotes items with a guaranteed reduced environmental impact throughout their entire life cycle. They help people make more informed buying decisions.

Why calculate PCFs?

Just as businesses track their finances to improve profitability, they complete PCFs to understand and reduce their climate impact.

PCFs help companies:

• Identify where emissions are highest in a product's life cycle
• Find opportunities to improve efficiency
• Make better design choices
• Compare different manufacturing options

In many cases, these improvements help reduce the cost of making a product. So, building PCFs can lead to financial gains too.

Different scopes of PCF measurements

When measuring a product’s carbon footprint, you need to decide where your measurement starts and stops. This is called its scope. It’s like drawing a boundary line around which parts of your product’s life you’ll measure.

There are different scopes for PCF measurements, but two of the most common are cradle-to-gate and cradle-to-grave. Manufacture 2030 focuses on cradle-to-gate PCFs as it enables you to focus on emissions in your own operations, making it easier to identify and address internal inefficiencies.

1. Cradle-to-gate PCF

• Starts at raw material extraction (cradle)
• Ends when a product leaves the factory (gate)
• Best for: intermediate products that will be used by other manufacturers.
• Example: Measuring emissions for aluminum sheets that will become drinks cans.

2. Cradle-to-grave PCF

• Starts at raw material extraction
• Ends when the product is disposed
• Best for: consumer products.
• Example: Measuring emissions for a smartphone from production through years of consumer use to eventual recycling.

Product carbon footprint vs life cycle assessment: What's the difference?

While both product carbon footprints (PCFs) and life cycle assessments (LCAs) assess the environmental impact of a product, there are key differences:

A PCF focuses on climate change only – typically measured through greenhouse gas emissions. An LCA, on the other hand, is much broader, covering 16 different impact categories, from water use and toxicity to land use and resource depletion. Climate change is just one of these.

🔍 The diagram below shows how it works:

• On the left are different emissions or substances a product might cause across its life cycle.
• In the middle are the environmental issues those substances contribute to. For example, mercury and benzene contribute to human toxicity.
• On the right are the real-world consequences such as impacts on human health, ecosystems, or resource availability
  
  

Think of it this way: A PCF is like checking your blood pressure. An LCA is a full medical exam. Both are useful, but they serve different purposes.

PCFs are quicker and more focused, which is ideal when you want to understand and reduce your climate impact. LCAs take longer and cost more but give you a complete view of your product’s environmental footprint.
