How Loamra turns invoices, meter reads and supplier replies into a footprint you can defend, and a plan you can act on.
Sources
Where the data comes from
Loamra connects to the systems you already pay for: half-hourly energy meters, utility bills, fuel cards, travel bookings and the purchase ledger in your accounts package.
Suppliers answer a short request with their own figure for what they sold you. Nothing is typed in twice, and every number keeps a link to the file it came from.

Calculation
How each number is worked out
Each line is an activity multiplied by an emission factor: kilowatt-hours of gas, litres of diesel, tonnes of steel. Factors come from the UK government’s conversion factors and licensed life-cycle databases, and each one carries its source and year.
Leeds plant gas meter, March
118,400 kWh
Emission factor, natural gas, 2025
0.18290 kg per kWh
Result
21.66 t CO2e
Rolls up to
Scope 1, Natural gas, coating ovens
Estimates
How estimates are marked
Where there is no activity data yet, spend is multiplied by an industry average. Those lines are hatched in every chart and scored for quality, so nobody mistakes an estimate for a measurement.
When a supplier replies, their figure replaces the estimate and the change is logged.
Targets
How targets and plans are set
Your target starts from a base year and follows a straight line to 2030, the same shape the Science Based Targets initiative uses for a 1.5°C pathway. Each initiative is modelled against the line, with its cost and the year it lands.
Assurance
What your auditors see
Auditors get a read-only seat. They can open any figure and follow it back to the meter read or invoice, see which factor was applied, and read who changed what and when.
