What’s the difference between upstream and downstream emissions?

Understanding upstream and downstream emissions is key to managing your environmental impact. These terms refer to different stages in a product’s life cycle, both of which contribute to your carbon footprint.

Upstream emissions

These are the greenhouse gas (GHG) emissions generated before your product or service reaches the end user.

Examples include:

• Extracting raw materials (e.g., mining metals)

• Manufacturing components

• Transporting materials to production sites

📱 For a smartphone, upstream emissions cover activities like mining rare earth metals, assembling parts, and shipping the phone to retailers.

How to reduce them:

• Source materials sustainably

• Choose suppliers with low-emission operations

• Improve production efficiency

Downstream emissions

These emissions occur after the product leaves your hands during usage, disposal, or recycling.

Examples include:

• Energy used during product operation

• Waste generated at end-of-life

• Emissions from shipping to consumers or final users

📱 For a smartphone, downstream emissions include the electricity it uses while charging and emissions from its disposal or recycling process.

How to reduce them:

• Design for energy efficiency

• Encourage proper recycling and reuse

• Educate customers on sustainable use

By addressing both upstream and downstream emissions, companies can better understand the full life cycle impact of their products and take action where it matters most.
