Decarbonising our business


Reducing our business carbon footprint


Total NGN greenhouse gas emissions reduction between 2023/24 and 2024/25

Our Scope 1 and 2 business carbon footprint (market based, excluding shrinkage) is stable.

In 2024/25 our emissions were 0.4% higher than 2023/24 and 39% greater than our annual target.

We purchase only certified renewable electricity for our premises, and have transformed our company car fleet so it now comprises 100% electric or hybrid vehicles, achieving our 2026 target. We're also helping our colleagues make low carbon choices for their own cars by offering an electric and hybrid vehicle leasing salary sacrifice scheme.


Electric or hybrid company car fleet

The main influence on our Scope 1 and 2 business carbon footprint is the external constraints we have experienced with the limited availability of suitable zero emission vans. NGN continue to search the market for fit for purpose battery electric vans. During the last quarter of 2024/25 we purchased a batch of 10 battery electric medium-sized vans to fully trial across the network. We anticipate this trial to begin in 2025/26. We also face constraints in the availability of public electric vehicle charging infrastructure across our region.

We measure the greenhouse gas emissions from our supply chain (‘Scope 3’). Our key Scope 3 emissions reduced by 3.75% between 2023/24 and 2024/25 and were 15.6% over our annual target. This is the result of constraints our supply chain face in decarbonising their vehicle fleets and machinery.
