Welcome to the Sumday Academy

Bust through the myths, clear the fog and make it easy for your team to get on with it.
Be audit you can be
In the past, carbon accounting has been done on the back of an envelope (or in a DIY calculator) based on generic data. Businesses couldn’t get away with this in financial accounting, and that's fast becoming the case for carbon. Auditable carbon accounting and reporting is the real baseline.
How are we different?
Education first - train your team and build internal knowledge
Sumday works for accountants and businesses of any size - enjoy the efficiency of using the same accounting software as your SMB suppliers
Accessible and affordable - subscription pricing that doesn't cost the earth, so you can focus on saving it.
