Warning signs: Minimal board time allocation, delegated decision-making, superficial reporting

Siloed Approach

Problem: Climate governance separate from business governance
Solution: Integration with existing governance structures and processes
Warning signs: Separate reporting lines, different risk frameworks, inconsistent decisions

Inadequate Information Flow

Problem: Board lacks timely, relevant climate information for decision-making
Solution: Design information systems to support board decision needs
Warning signs: Late reporting, generic information, lack of forward-looking insights

Overemphasis on Compliance

Problem: Focus only on regulatory compliance rather than value creation
Solution: Balance compliance with strategic opportunity identification
Warning signs: Compliance-only reporting, limited strategic discussion, reactive approach
