How are the results broken down

Scope 1 - Fuel type

Direct emissions from fuel combustion in owned/leased vehicles and plant.

Fuel use provides the most accurate measurements for emissions and Scope 1 relates to all direct fuel emissions, that your company generates from its vehicles, plant and machinery.

Scope 2 - Electricity, Heat & Steam

Emissions from purchased electricty, heat and steam

Electricity generation alongside purchased heat and steam comprises Scope 2 emissions. This does not include emissions from transmission and distribution which is Scope 3.


Scope 3 - Air, Rail, Vehicles, Supply Chains

Indirect emissions from use of third party services that create emissions.

For the majority of companies the biggest impact is Scope 3 which is the emissions that derive mostly from providers of transport for individuals or freight and from supply chains.
