A major consideration in determining and reducing the CO2 footprint is that of the scope. (Largely) in accordance with the GHG Protocol, SKAO defines 3 scopes (see adjoining scope diagram):

  • Scope 1 Emissions or direct emissions (e.g. commercial vehicle traffic and individual fuel consumption);
  • Scope 2 Emissions or indirect emissions (e.g. electricity purchased);
  • Scope 3 Emissions or other indirect emissions (e.g. travel by train).

The action plans cover Scope 1, 2 and 3.
