Climate Governance for UK Boards: From TCFD Compliance to Strategic Integration Under UK SRS
Key Takeaways
- UK SRS elevates climate governance from a disclosure checkbox to a substantive requirement: boards must demonstrate active oversight, competency, and integration of climate into strategic decision-making
- The transition from voluntary TCFD to mandatory UK SRS governance requirements means boilerplate governance disclosures are no longer acceptable
- Director fiduciary duties under the Companies Act s172 are increasingly interpreted to include climate risk consideration, creating potential personal liability for inadequate oversight
- A growing climate skills gap on UK boards means many companies need to invest in board training, advisory appointments, or dedicated sustainability committee structures
- The audit committee’s role expands to oversee climate data assurance as UK SRS requires limited assurance from the second year of mandatory reporting
From TCFD to UK SRS: What Changes at Board Level
TCFD’s governance pillar asked companies to describe the board’s oversight of climate-related risks and opportunities, and management’s role in assessing and managing those risks. In practice, many companies treated this as a narrative exercise: a paragraph describing the board’s role, a reference to terms of reference, and a statement that climate was discussed at board meetings.
UK SRS raises the bar significantly. The governance disclosures under UK SRS S1 require companies to demonstrate:
- Active oversight: Evidence that the board regularly reviews climate-related information, not just receives it. This means documented board discussions, challenge of management assumptions, and explicit board decisions on climate matters
- Competency: Disclosure of whether and how the board has access to the skills and expertise needed to oversee climate-related risks. This includes identifying specific board members with relevant expertise and describing any training undertaken
- Integration into strategy: Evidence that climate considerations are embedded in capital allocation, M&A decisions, business planning, and risk appetite, not treated as a separate sustainability agenda item
- Targets and accountability: Whether management remuneration is linked to climate targets, and how the board monitors progress against those targets
Director Liability and Fiduciary Duty
The Companies Act 2006 s172 requires directors to promote the success of the company for the benefit of its members as a whole, having regard to (among other things) the impact of the company’s operations on the community and the environment. While s172 has not yet been tested in UK courts specifically on climate grounds, the legal direction of travel is clear:
- The Commonwealth Climate and Law Initiative has published analysis arguing that directors who fail to consider climate risks may breach their fiduciary duties
- ClientEarth’s derivative action against Shell’s directors (while unsuccessful on procedural grounds) demonstrated that climate-related board conduct can be subject to legal challenge
- The FRC’s revised UK Corporate Governance Code emphasises the board’s responsibility for sustainability oversight
- Insurance industry guidance now highlights climate governance as a factor in D&O (directors’ and officers’) insurance underwriting
The practical implication: boards that cannot demonstrate they have considered and managed climate risks face not only regulatory sanctions under UK SRS but potential liability under existing company law.
Board Committee Structures
There is no single correct committee structure for climate governance. Common approaches include:
Option 1: Full Board Responsibility
Climate oversight sits with the full board, with climate as a standing agenda item. This approach ensures that all directors engage with climate issues and that climate is integrated into overall strategic discussions. However, it risks climate being crowded out by other board business.
Option 2: Sustainability/ESG Committee
A dedicated board committee with specific terms of reference for sustainability oversight. This provides focused attention and typically includes directors with relevant expertise. However, it risks creating a silo where other directors defer to the committee rather than engaging personally.
Option 3: Integrated into Existing Committees
Climate risks are distributed across existing committees: the audit committee oversees climate data assurance, the risk committee assesses climate risk, and the remuneration committee sets climate-linked performance metrics. This integrates climate into existing governance processes but requires coordination to avoid gaps.
Whatever structure is chosen, UK SRS requires clear disclosure of how it works in practice, not just in theory.
The Climate Skills Gap
Research by Chapter Zero (the directors’ climate forum) and the FTSE Board Report consistently find that:
- Fewer than 20% of FTSE 100 board members have demonstrable climate or sustainability expertise
- Many boards rely on a single “sustainability champion” rather than building collective competency
- Non-executive directors, in particular, often lack the technical knowledge to challenge management on climate assumptions
Addressing the skills gap requires a combination of:
- Board training: Structured climate literacy programmes covering the science, regulation, and business implications of climate change
- Advisory appointments: Adding directors with specific climate or sustainability expertise to the board
- External advisors: Engaging climate advisory firms to brief the board on sector-specific risks and regulatory developments
- Board evaluation: Including climate competency in annual board effectiveness reviews
The Audit Committee’s Expanding Role
As UK SRS introduces mandatory limited assurance of climate disclosures, the audit committee’s role expands to cover:
- Assurance provider selection: Whether climate assurance is provided by the statutory auditor or a specialist provider, and how independence is maintained
- Data quality oversight: Reviewing the reliability and completeness of climate data, including Scope 3 methodologies and assumptions
- Internal controls: Assessing whether internal controls over climate data are comparable to those over financial data
- Connectivity with financial statements: Ensuring that climate assumptions (e.g., asset impairment, provision estimates) are consistent between UK SRS disclosures and the financial statements
What Good Practice Looks Like
Leading FTSE 100 companies demonstrate effective climate governance through:
- Board-approved climate transition plans with clear milestones and accountability mechanisms
- Regular board-level review of climate metrics (at least quarterly), with deep-dive sessions on emerging risks
- Executive remuneration explicitly linked to climate targets (typically 10–20% of variable compensation)
- Published board skills matrices that include climate competency as a specific category
- Independent assurance of climate data overseen by the audit committee with clear terms of engagement
Practical Steps for Boards
- Conduct a governance gap assessment: Map your current climate governance against UK SRS requirements to identify specific disclosure gaps
- Upgrade committee terms of reference: Ensure at least one board committee has explicit responsibility for climate oversight, with appropriate reporting lines
- Invest in board climate training: Commission a structured training programme covering climate science, regulation, and sector-specific risks
- Review remuneration linkage: Assess whether executive remuneration includes meaningful climate-linked performance metrics
- Prepare for assurance: Brief the audit committee on UK SRS assurance requirements and begin discussing provider selection
- Document everything: UK SRS requires evidence of governance in action, not just policies on paper. Ensure board minutes, committee reports, and decision records capture climate discussions
