The world is hotting up and so are boardroom debates. This briefing will give you the facts and sources you need to be an informed climate-friendly NED, but also to add value - these two must go together. I suggest you read all the key takeaways, scan the policies grouped by area, and drill down to the ones that are coming up for your sector and your business. I use this document to improve my own briefings to colleagues and to prepare for board meetings. I share relevant links with subcommittees and insert single points into emails. You can find good contemporary taglines here, which I rotate for some of my boards at the end of personal messages. This is a rich trove, and you can continuously mine it.

Summary Briefing

This Summary Briefing highlights the essential need-to-knows for NEDs in terms of emerging policy and regulatory developments announced from the end of April 2025 to early September 2025, offers suggested prompts for boardroom discussions, and includes some upcoming key events and UK Government consultations regarding climate policy that may be useful for Boards to be aware of.

The full briefing below offers more detail on each of the key policy areas relevant for boardrooms in regard to the climate agenda.

Key takeaways for Non-Executive Directors

Full Briefing

Introduction

Our quarterly UK policy briefing aims to highlight the latest developments in UK climate policy relevant to Non-Executive Directors (NEDs). Carrying on from our last briefing, this edition considers policy developments from April to the early September 2025.

While there have been a number of key policy developments over this period, there remain a number of policy action gaps, bringing the UK Government’s investment priorities into clearer focus. Significant levels of green investment were mobilised in the Chancellor’s June Spending Review. Recent analysis shows that the UK’s net zero sectors are growing faster than the wider economy. Although recent statements from the Office for Budget Responsibility (OBR) have indicated that significant risks to the UK’s public finances remain, in May, the International Monetary Fund (IMF) upgraded the UK’s growth forecast, saying that “an economic recovery is underway”.

The end of June saw London Climate Action Week (LCAW), which attracted record attendance. During LCAW, regulators signalled the forthcoming rollout of new UK Sustainability Reporting Standards (SRS), which is set to endorse and adopt International Sustainability Standards Board (ISSB)-aligned reporting standards. The new SRS are expected to form the foundation of the UK’s revamped Sustainability Disclosure Framework, with the UK Government also reaffirming its commitment to climate transition plans for large companies and financial institutions by 2026. There was a strong push towards embedding nature-related financial disclosures, reflecting growing convergence between climate and biodiversity risk regulation. Increasing focus on nature also extended to discussions on voluntary carbon markets and carbon credit compliance, which saw a strong call for more strategic business-government collaboration on improving the integrity and financial viability of carbon market participation as a practical component to the UK’s emissions reductions journey, through announcements including the launch of the Coalition to Grow Carbon Markets. In July, HM Treasury launched the Transition Finance Pilot, with a focus on identifying and reducing the regulatory barriers high-emissions businesses face in investing in decarbonisation, aiming to attract up to £200 billion in investment.

Suggested boardroom discussion prompts

Board discussion prompts

  1. Does our business strategy or transition plan reflect the latest policy and regulation developments? Have these changes opened up any new opportunities for industry collaboration, investment or funding?
  2. Are any of the ongoing Government consultations, including the UK Sustainability Reporting Standards (SRS) and voluntary carbon markets consultations, relevant to our net zero activity and transition planning? Should we be capitalising on these opportunities to engage?
  3. Are we fully aware of what these new regulatory requirements might mean for us? Can we start to prepare our reporting teams now to get ahead of the curve? Do we need to expand or adapt our reporting to align with current and forthcoming regulatory changes, and/or incorporate any risks not currently accounted for?
  4. Do we as a board have sufficient insight into what budgetary assumptions are being made about the impacts of trade and climate policy on our supply chains, costs, and growth? How resilient are our plans if these external pressures intensify and/or change?
  5. Given the divergence in global climate policy directions, how can we ensure our policies and practices both maintain compliance and demonstrate leadership? How confident are we that our leadership team is positioning us to respond proactively to the shifting international policy environment, while still aligning with UK and European policy drivers that may set us apart?
  6. Does the board have a strategy around potential long-term consequences of the ICJ advisory opinion?
  7. Could we engage with policy stakeholders around the UK Government’s new strategies and proposed pathways? What business perspectives and policy actions set out in the Government’s Modern Industrial Strategy and 10-Year Infrastructure Strategy can we integrate into our transition planning?
  8. Given the direction of travel signposted in the UK Government strategies, including the Modern Industrial Strategy, do we need to review our talent strategy? Do we have the right skills and competencies within our executive team to guide our transition?
  9. Are there steps we can take to prepare for forthcoming UK Government legislation including the Planning and Infrastructure Bill and the refreshed Carbon Budget Delivery Plan? Could these developments impact the potential speed and cost of our green transformation?
  10. What insights can we take on board from the CCC’s progress reports on adaptation and emissions reductions? Are there opportunities for us to think differently about how we mitigate and manage emissions? Have we considered adaptation fully in our transition planning? Do we have the right information, skills, and competencies on the board to help us respond to these challenges?

Relevant policy resources

For NEDs interested in more in-depth research relating to current UK policy trends, there are a range of resources available, including:

  • The SBTi Trend Tracker 2025 was released in August, analysing SBTi data from January 2024 to June 2025 to offer up-to-date insight into how businesses worldwide are aligning with climate science and setting validated net zero targets. SBTi finds that the number of businesses setting long-term net zero targets has increased by 27% within this 18-month period, with the number of companies setting targets being 97% higher in Q2 of 2025 than Q4 in 2023.
  • InfluenceMap has released a Primer on Corporate Climate Policy Engagement Disclosure, finding that nearly three-quarters on the world’s largest companies now report some information on their direct climate policy engagement. Drawing on data from its LobbyMap platform, InfluenceMap outlines key suggestions for improving the quality and accuracy of corporate climate policy disclosures, to better meet the changing expectations of both investors and regulators.
  • Beyond Fossil Fuels, E3G, and We Mean Business Coalition published the Global Business Poll: Powering Up report in April 2025. The poll surveyed over 1,400 mid-market and large company executives, finding that 97% of executives support a rapid shift away from fossil fuels to renewables-based energy system. The data, broken down into country-level analysis, identifies key financial and policy barriers to the transition notably, insufficient national infrastructure for storing and distributing renewable electricity, insufficient availability of renewable electricity sources, policy and regulatory support, and absence of detailed energy policies and plans.
  • An April report from the City of London Corporation in collaboration with the UK Carbon Markets Forum, The role of the UK in carbon markets: a path to global leadership, offers insights for UK-based carbon market stakeholders, including the Government, investors, and advisors, on how to enhance the development of a well-functioning market and further the UK’s leadership in the field.
  • The World Economic Forum (WEF) has published an article, Why business leaders should advocate for science-aligned climate policy, supported by the International Climate Councils Network, Ambition Loop, E3G and InfluenceMap.
  • The Coalition of Finance Ministers for Climate Action (CFMCA) released A Global Survey of Ministries of Finance in June, outlining the pressing policy questions Ministries of Finance face in driving green and resilient transitions, and the analytical tools they are using to address them.
  • Green Alliance has released a report, The nature of our economy: implementing the Dasgupta Review, which provides in-depth analysis on the 2021 Review’s key findings, with a particular focus on offering practical proposals across three areas: the macroeconomy, microeconomy, and political reform. The aim of solutions-oriented proposals is to inform an economic decision-making framework that accounts for the true value of nature.
  • The Local Government Association has released a report, Empowering local climate action: Advice to government, presenting its advice on how to build collaboration between the UK government and councils to deliver on shared climate commitments. The report suggests a range of policy actions to take across cross-cutting issues including energy, green finance, and skills development.
