How a site is counted

How one site's month is counted.

Four sources, four bills, one total. Scroll through it.

1 · Sources

Set up the sources.

Anything that burns fuel, leaks gas or draws power gets a code and a category. That is done once.

2 · Scope 1 · Stationary combustion

Diesel, from the April fuel bill. The litres are the only number typed in.

The first confirmed figure fixes the DEFRA edition for the year.

3 · Scope 1 · Mobile combustion

LPG, from the cylinders swapped in April. Vehicles are reported apart from the boiler, as mobile combustion.

4 · Scope 1 · Fugitive

Nothing burns. The amount topped up at service is the amount that leaked, counted by the gas's warming power.

5 · Scope 2 · Purchased electricity

The power station burns the fuel. The site counts its share from the meter bill, with the grid factor for the year.

No grid factor set yet. The kWh are kept; the kilograms appear once it is.

6 · The site's footprint

Each line still points to its source and its bill.
