Climate transition action plan shareholder vote

National Grid to seek shareholder approval for climate transition action plan

The National Grid Board today announces its intention to put its climate transition plan before shareholders and seek a non-binding advisory vote on the Company's climate change-related 'net zero' commitment[1] and associated target[2], and its action plan to achieve its interim 2030 net zero target.

The action plan will set out the Company's commitment to becoming a net zero business in its Scope 1 and 2 greenhouse gas emissions by 2050 or sooner, its Scope 3 reduction target (in a manner consistent with the Task Force on Climate-related Financial Disclosures (TCFD)) and to transition our business to align with the goals of the Paris Agreement.

As a Principal Partner to the UK Government for COP 26 National Grid is fully committed to its role in tackling climate change, and as a responsible company, for our people and the communities that we serve. We embrace the opportunity to play our role in helping achieve these challenging goals building on the launch of our Responsible Business Charter published in October 2020 and our recent ESG virtual event on the Future of Gas.

The Company's environmental targets include:

·  Achieving net zero by 2050. We will reduce Scope 1 and 2 greenhouse gas (GHG) emissions 80% by 2030, 90% by 2040, and to net zero by 2050 from a 1990 baseline.³

·  Reducing Scope 3 GHG emissions for the electricity and gas we sell to our customers (making up 80% of our Scope 3 emissions) by 20% by 2030 from a 2016 baseline.

·   Reducing SF₆ emissions from our operations 50% by 2030.

John Pettigrew, Chief Executive said, "We welcome this increased transparency with our shareholders and hope it will improve the understanding of our strategy and environmental commitments. Engagement with our key stakeholders has been a crucial part of defining our net zero commitments and ambition and it has helped us better understand their expectations to develop a path we believe is consistent with the Paris Agreement and consistent with TCFD.

Our aim is to be a leading utility globally in demonstrating the technical and commercial solutions that will help achieve net zero for the energy sector. We continue to work closely with the UK Government, administrations in Scotland and Wales, US partners, and peers and partners around the world to demonstrate these solutions as part of our work for COP26⁴."

The Company will share its climate transition action plan ahead of its AGM in July 2022. The reporting will be updated on an annual basis alongside our Annual Report and Responsible Business Report, with a resolution at each AGM for shareholders to receive, consider and approve the reporting. The first year the Company will report on its annual progress against the plan will be 2022.

We are also pleased to announce that the next live event, in our "Grid Guide to…" series will be held on 30^th June, focusing on our role in the "Decarbonisation of Transport". This series of events focuses in on specific topics, across all ESG themes, aiming to give a deeper understanding of the projects National Grid is working on, and how the company can make a real difference to the energy transition. Information on the "Grid Guide to…" series can be found here, and more details on this event will be provided in due course.
