Net zero pathway
Your pathway, drawn before the first call.
Move the target year and the bars re-shape. This is the model we fill with your real data in the first six weeks.
Try it
Move the year and watch the bars.
Drag the marker, tap a year or use the arrow keys. Switch a scope off to see how much of the total sits in your value chain.

How to read it
Four things to look at.
The chart above is a model with sample figures. Here is what each part means, and what it becomes once your numbers are in it.
Each bar is one year of emissions, from today on the left to 2050 on the right. The height is tonnes of CO2e across the scopes you have switched on.
Drag it to the year you want to reach net zero. An earlier year makes every bar before it shorter, because the same cut has to happen in less time.
This is where emissions go if nothing changes. The space between the dashed line and the bars is what the plan avoids.
The target year, the cut needed every year to get there, and the total tonnes avoided by 2050. They move together with the marker.

With your data
The bars
Your first bar comes from twelve months of real energy, fuel, travel and purchasing data.
