Decarbonising our business


Reducing our business carbon footprint


Total NGN greenhouse gas emissions reduction between 2022/23 and 2023/24

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

In 2023/24 our emissions were 0.1% higher than 2022/23 and 27% 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 influences on our Scope 1 and 2 business carbon footprint are the external constraints we have experienced with delayed delivery of 200 new diesel vehicles ordered in the last two years, and the limited availability of suitable zero emission vans. NGN continued to search the market for a fit for purpose battery electric van. We have purchased a batch of 10 battery electric medium-sized vans to fully trial. Delivery dates are subject to worldwide supply chain issues that are still being experienced by fleet operators, and we anticipate this trial to start in 2025.

We also measure the greenhouse gas emissions from our supply chain (‘Scope 3’). Our key Scope 3 emissions increased by 14% between 2022/23 and 2023/24 and was 17.9% over our annual target. This was principally influenced by completion of a greater mains replacement workload during 2023/24.
