OUR OPERATIONAL
EMISSIONS FOOTPRINT

We have been measuring and publishing our operational emissions footprint since 2007
foot graph

Electricity
63% of total emissions

Scottish Water and its PFI partners consume 576GWh per annum to deliver vital water and waste services. Electricity is by far the largest contributor to our operational footprint at 160ktCO2e tonnes.

Transport & Travel 6%

This is mainly driven by the 19 million miles travelled by our fleet, along with business travel. Annually, we produce 16ktCO2e from transport and travel.

Process emissions
17% of total emissions

These are the emissions which naturally come from wastewater and the treatment of it which include N2O and CH4. Annually, this equates to 43ktCO2e.

Other 2%

This covers the use of on site fuel for standby generation, emissions from waste disposal and from refrigerant and electrical insulation gases.

Gas
14% of total emissions

The use of fossil fuels comes predominantly from the gas used for the thermal drying and processing of sludge at PFI Wastewater Treatment Works and in heating our offices. Annually, we produce 38ktCO2e from gas.

Self-generated
renewable electricity -2%

We currently produce and use 53GWh
of electricity per annum helping to reduce our carbon footprint by 2%.
