Partner responsibility and to hold suppliers to sustainability standards

Purchasing sustainably

In April 2022 we launched a new Supplier Code of Conduct to embed sustainability in our supply chain.

We have set a target to achieve 80% of our supply chain by value compliant with our code by March 2026.

By March 2024 we had already achieved 82%.

Supporting suppliers

We are proud members of the Supply Chain Sustainability School, with Bronze status.

Through this partnership, we support our suppliers in improving processes and enhancing their overall environmental impact.

In 2024 our suppliers engaged with sustainability-related training materials 2,508 times on the platform.

Data sharing for Net Zero

In 2023 we used insights gained from stakeholder engagement to build a new NGN Open Data Portal. Initially, the portal provided access to four data sets.

In 2024 this has been extended to 20 data sets. The data is classified as ‘open’ and licenced to use without restriction.

So far there have been 700 downloads by site users.
