Scotland's Premier Net Zero Port

Scoping Our Emissions

As part of our vision to become the UK’s first net zero port by 2040, we measure the carbon footprint associated with port activity.

In 2025, our carbon footprint was independently verified at 65,277.4 tonnes of carbon dioxide equivalent (tCO²e).

Scope 1

Scope 1 emissions reduced by 12.1%, due to lower diesel use in our equipment, vehicles and vessels. Natural gas remains the largest contributor to scope 1 (98%), reflecting its use to heat our buildings and workshops. We have made significant progress in recent years in tackling our scope 1 emissions, with a reduction of almost 80% since 2022.

Scope 2

Scope 2 emissions reduced by 1.5% on a market-based basis. We continue to move to all REGO (Renewable Energy Guarantees of Origin) certified electric contracts within the port estate and expect to see further reductions in the next reporting period.

Scope 3

Scope 3 emissions reduced by 3.5%, led by a 57.4% fall in downstream leased asset emissions. This reflects a combination of lower tenant energy use and continued improvement in the quality of data we receive from tenants as we continue to support their decarbonisation goals.

Total vessel emissions rose by 0.7% despite the drop in vessel traffic, as vessels spent an average of three additional minutes at berth compared with 2024. Our carbon intensity metric - kg of CO²e per vessel tonnage handled – increased from 1.3 in 2024 to 1.4 in 2025 as the tonnage handled reduced year-on-year.

We expect to see the benefit of introducing shore power at ten berths reflected in the next reporting period.

“Port of Aberdeen's activities are a key enabler of the exciting energy transition. Great British Energy looks forward to partnering with the port to help accelerate this work.”

Reducing vessel emissions

Shore power is a proven technology for reducing vessel emissions at berth.

In 2025, Port of Aberdeen completed three shore power infrastructure project which now provide clean electricity at 10 berths.

The £4million ‘Shore Power in Operation’ demonstrator project was supported by the Department for Transport’s Zero Emissions, Vessels and Infrastructure (ZEVI) competition funded by UK Government and delivered in partnership with Innovate UK.

The demonstrator project could save up to 60,000 tonnes of CO² equivalent over 20 years, the same as removing more than 2,000 cars from the road every year.

Shore power infrastructure was also installed at Regent Quay for Bibby Marine’s electric Service Operation Vessel and completed works for Serco NorthLink’s passenger ferries.

Industry recognition

Port of Aberdeen was awarded the Sustainable Supplier Award at the 2025 Scottish Green Energy Supply Chain Awards,

The sustainable supplier accolade recognises and celebrates the port’s strategic net zero vision to becoming the UK’s first net zero port by 2040, and significant contribution to long-term maritime decarbonisation through the delivery of its £4 million Shore Power in Operation project – the first of its kind in the UK to address Scope 3 emissions from client vessels, driving net zero progress across the wider supply chain.

“Port of Aberdeen is proud to be setting the standard for maritime decarbonisation in the UK. Guided by our Net Zero Strategy, we are committed to sustainable growth and determined to lead the way towards becoming the UK’s first net zero port by 2040."
