Scottish Water and its PFI partners use 199GWh of gas and fuel oil per year.
The majority of the gas is used in the thermal drying and processing of wastewater sludge.
Fuel oil is used for standby generation of power at our assets in the event of power supply problems.
The remaining gas is used for heating in our buildings.
This leads to 38ktCO2e per annum.

These tables illustrate the key activities we are
exploring to reduce our gas and fuel oil emissions.
We will keep these under review
with our expert advisory panel.

Scottish Water has established a framework for the supply of sustainably sourced hydrotreated vegetable oil that can be used by both Scottish Water and its construction partners. It’s a drop in fuel replacement that reduces emissions by 90% compared to conventional diesel.
Over the last year it has been widely adopted by our construction partners, displacing diesel use in excavators, cranes and other heavy plant. It is also being used to fuel generators to provide power for remote construction sites.
On our water mains rehabilitation programme its adoption is expected to reduce emissions by nearly 30%.
