OUR 2020/21 OPERATIONAL
EMISSIONS FOOTPRINT
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.
Electricity
59% of total emissions
Scottish Water and its PFI partners consumed 575GWh per annum to deliver vital water and waste services. Electricity is by far the largest contributor to our operational footprint at 146ktCO2e tonnes.
Transport & Travel 6%
This is mainly driven by the 17 million miles travelled by our fleet, along with business travel. Annually, we produced 13ktCO2e 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.
Process emissions
23% of total emissions
These are the emissions which naturally come from wastewater and the treatment of it which include N2O and CH4. Annually, this equated to 58ktCO2e.
Other 3%
This covered 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%.
Gas
12% 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 produced 30ktCO2e from gas.
Self-generated
renewable electricity -2%
We produced and used 55GWh of electricity per annum helping to reduce our carbon footprint by 2%.

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%.
Scottish Water has been a partner in a project, led by the local community and supported by the National Lottery’s Community Fund, to regenerate the site once occupied by Douglas Primary School as a multi-functional greenspace.
Our team worked with the community to incorporate sustainable drainage features in the new park, which store and slowly release the rainwater that falls on surrounding roads and rooftops during storms. This eases pressure on the combined sewer network in the local area, as well as helping to protect the local environment and reduce flood risk from the Dighty Burn. Importantly, the community has been able to realise its wider aims by creating an attractive outdoor space that also provides a home for wildlife; and can be enjoyed for play, relaxation, exercise, events and the growing of food.
Planning is now underway to introduce more sustainable water management measures in the area surrounding the park, with the aim of disconnecting over 40,000m2 of land area from the combined sewer network; and helping to enable the development of more social housing in Douglas. Engagement with the community, including schools and other key stakeholders, is being carried out to help shape the proposals.
Work with the community and Dundee City Council on sustainable drainage for Douglas has helped to inspire the Water Resilient Dundee partnership. This initiative is now pursuing opportunities for more sustainable management of stormwater across the city, reducing flood risk in communities, creating capacity for development and enhancing amenity.
