Why Data Collection Matters

The quality of your carbon footprint depends entirely on the quality of your input data. Start with what you have and improve over time.

Natural gas kWh, transport fuel litres, other fuels, and refrigerant recharge data.

Electricity kWh from utility bills or half-hourly metering data.

Procurement ledger, business travel data, employee commuting surveys, waste tonnage, and freight data.

Start with your finance team, set up a data calendar, centralise your data, and engage facilities managers early.

Most data you need already exists in your finance and facilities systems

Start with what you have — estimates are better than nothing

Scope 1 needs fuel and gas data; Scope 2 needs electricity data

Scope 3 can start with procurement spend data (spend-based method)

Set up a regular data collection routine to improve quality over time
