Sage Earth does a lot of heavy mathematics on your behalf to make the act of calculating a businesses' carbon footprint as simple and quick as possible.
In doing this, we also strive to be completely transparent in our workings, because for obvious reasons the data used to further any conversation about the climate emergency needs to be absolutely trustworthy.
For this reason, we've decided to publish a list of the references used across the platform which were chosen to help users understand the scale of their impact. Each was carefully chosen to make carbon footprint contributions relatable to an every-day equivalent.
We've also tried to select a comparison that is relevant to the section of the company profile that has been completed.
People (staff commuting)
Example chosen: a single train journey from Bristol to London.
Numbers and sources for data used in calculation:
171 km = distance between Bristol and London (ref: here)
