The purpose, vision and values are powerful tools to build trust, by demonstrating the commitment to the societies being served is genuine; not only through our traditional services, but also championing the kind of change that facilitates progress and meaningfully improves lives.

Sustainability and Supply Chain

Sustainability is helping us find a better way to do business; saving money, reducing environmental impact and building strong relationships with our local communities and stakeholders.

Our environmental sustainability framework identifies three themes: our climate commitment; responsible resource use; and, caring for our natural environment.

We also recognise that a diverse workforce and an inclusive culture can bring significant value to our business, so we want to attract applicants from under-represented groups. This also extends into our supply chain which is key to delivering our project commitments.

Fundamentally we don’t just supply power to our communities, we are part of them. A strong community is good for the people who live there, good for our business and good for the wider economy.

We aim to apply the same principles of responsibility and sustainability to our wider operational scope and significant activity is being undertaken within the procurement function with a strong focus on supply chain CSR and sustainability.

We have a value operating model that outlines the strategic areas being addressed to embed CSR and sustainability into the supply chain.

UK Reduction of Capital Carbon in Infrastructure: Transmission (ROCCIT)

National Grid Transmission, Scottish & Southern Electricity Networks Transmission and Scottish Power Energy Networks Transmission have formed a collaborative group – UK ROCCIT (UK Reduction of Capital Carbon in Infrastructure: Transmission) in order to address and manage the capital carbon emissions associated with developing our networks. As each company supports the low carbon transition through the development of a transmission network which will support the integration of renewables onto the grid, it is increasingly important to consider the carbon emissions associated with building this infrastructure.

The aim of the ROCCIT group is to develop a consistent approach and common methodologies to managing capital carbon emissions and to collaboratively work with our supply chain in a consistent way to create an industry wide approach to managing capital carbon emissions.
