What are Scope 1, 2 & 3 emissions?

Sometimes it can be confusing trying to work out your carbon footprint, especially when there are scope 1, 2 & 3 emissions to consider. But as complicated as it sounds, it is very easy to learn.

Scope 1

Scope 1 emissions include all Greenhouse Gas emissions that your company makes directly.

This includes all energy use within the building you operate in, and all company owned equipment and vehicles. This is the most straightforward scope to calculate. For example, it includes on-site gas boilers, air conditioning units & petrol & diesel you put in company cars.

Scope 2

Scope 2 emissions include all Greenhouse Gas emissions that your company makes indirectly.

Put more simply, these are the indirect emissions from the electricity you purchase and use. This includes electricity, steam, heating or cooling for own use.

Scope 3

Scope 3 emissions include all Greenhouse Gas emissions from sources or activities you can’t own or control. This is also the most difficult to calculate given their indirect nature.

This includes business travel, employee commuting (in vehicles not owned by your company), logistics, procurement and water/waste management. For example, tea brand Pukka found that 39% of their overall emissions come from their customers boiling a kettle to make the tea. This would fall under scope 3 emissions as Pukka has no control over this.
