Sustainability at Nominet

Driving positive progress

Find out how we’re playing our part through our sustainability initiatives, both big and small.

Journey to Net Zero

At Nominet, we’re committed to minimising the impact of our activities on the environment and achieving our net zero goal by 2050.

As part of our vision, we’re actively finding ways to reduce our carbon emissions through our Carbon Reduction Plan.

A Sustainable Future

Renewable Energy Sources

Power our office and data centres

Hybrid Working Policy

Reduces energy and emissions

Green Commuter Programme

Provides cycling and EV charging facilities

Technology-First Travel Policy

Reduces travel related emissions

Office Recycling Scheme

Reduces landfill waste

Nominet Forest

Since July 2019, Nominet has planted and protected over 18,000 trees, captured over 4,000 tonnes of CO2, and restored nine hectares of ecosystem across four projects.

To help the UK achieve Net Zero by 2050, Nominet invests in UK woodland projects including Arnott’s Loan in East Lothian and Doddington North in Northumberland.

Pathways to progress

Our Carbon Reduction Plan sets out how we will reduce our carbon footprint year on year and is completed in accordance with PPN 06/21.

Our emissions data is gathered and independently verified in accordance with ISO 14064-3:2019 Greenhouse gases – Part 3: Specification with guidance for the verification and validation of greenhouse gas statements.

Measuring Success

Since 2018, we’ve been gradually increasing the Scopes and categories we measure.

In January 2023, the Science Based Targets initiative (SBTi) approved Nominet UK’s near-time science-based emissions reduction target.

We commit to reduce our Scope 1 and Scope 2 GHG emissions by 42% by 2030, using 2020 as a base year, and to measure and reduce our Scope 3 emissions.

Our CARBON FOOTPRINT

We’ve verified our carbon footprint in accordance with ISO 14064-3.

Our Carbon Footprint – FY26

471.27

Market-based tCO2e

Our market-based footprint accounts for multiple country supplier emissions from our procured services related to data centres and UK renewable energy.

538.88

Location-based tCO2e

We’ve also calculated our location-based footprint.

In FY26 our carbon footprint decreased, which was largely attributed to:

Reduced electricity consumption
Lower fugitive emissions and fewer instances of business travel.
Planned infrastructure improvements contributed to decreased energy use in data centres.
A decrease in emissions associated with DNS queries, due to a reduction in energy and emissions intensity for electricity use.
DNS queries were reclassified under category 11 (use of sold products) to ensure better alignment with GHG protocol definitions.

Energy efficiency action taken

The volume of electricity has continued to reduce because of the transition from halogen to LED lighting in the office and plant and equipment optimisation. The planned infrastructure changes in data centres have reduced energy use, this is expected to continue in the next reporting period.
