Purpose

To frame user stories so they deliver value for both the user and the planet, making sustainability part of the conversation from the start.

<aside>

Use this tool:

• When writing or refining user stories.
• In backlog refinement or sprint planning.
• When a feature could be delivered in more than one way.

You'll get:

• A simple story format that captures user needs and environmental benefits in one place.
• A shared reference for impact‑friendly design and development decisions.
• Acceptance criteria that make sustainability testable. </aside>

How to use

1. Use the format:

   As a [user type]

   I want to [do something]

   So that [I meet my goal]

   In a way that [reduces harm or adds benefit for the planet]

2. Fill in each part using real context from your product and users.

3. Add relevant acceptance criteria (see below).

4. Tag the story with [Impact Tags] if needed.

What to consider

• Who is the user, and what is their goal
• What behaviours, choices, or constraints affect environmental impact
• How this story will scale if adopted widely
• Any trade‑offs between convenience, cost, and sustainability

Examples

As a frequent commuter

I want to see colleagues who travel the same route as me on the same days

So that I can arrange to share travel

In a way that reduces the number of cars on the road

As an online shopper

I want the option to collect my order from a nearby pickup point

So that I can reduce delivery trips to my home

In a way that cuts transport emissions and makes deliveries more efficient
