# Should an MSME track carbon emissions monthly or just once a year?

Canonical: https://senseible.earth/answers/track-carbon-monthly-or-yearly-msme

Track monthly, report yearly. Monthly records come straight from bills, catch missing documents while they can still be found, and show changes in time to act. The annual figure is then just the sum, not a rush at year end.

## Monthly habit

- Upload electricity and fuel bills when they arrive.
- Note production for the month.
- Check intensity against the same month last year.

## Annual report

Add the twelve months, explain gaps and estimates, and keep the documents for checks.

## What Senseible does here

Senseible reads fuel, electricity and production documents into dated, fingerprinted plant records, so the monthly intensity behind a compliance figure can be traced to its source.
