How We Work

ISG was created in response to a gap in the advisory landscape.

Too often, organisations are offered advice that is generic, fragmented, or shaped more by optics than outcomes. At critical moments, leaders can lack access to independent, evidence-grounded insight that helps them act with confidence.

We work with leaders who value clarity, credibility and sound judgement in complex and uncertain environments.

Our Model

An evidence-led advisory model

Our work combines scientific integrity, strategic clarity and commercial awareness.

We operate at pace, interpreting live developments across climate science, policy and markets, and translating them into decision-ready insight. The focus is on helping leaders understand what is changing, why it matters, and what it means for action.

While ISG’s work is anchored in climate, our approach reflects the wider geopolitical, economic and societal forces that shape risk, opportunity and leadership decisions.

Access with integrity

ISG works with deep access to global scientific and policy expertise, enabling clients to engage directly with the evidence shaping real-world decisions.

Access is carefully curated, independent and grounded in scientific rigour.

How we engage

Engagements are shaped around the moment a client is facing and the impact they need to make

We work flexibly, including:

  • Retained strategic advisory

  • Rapid, project-based analysis

  • Executive and board briefings

  • Curated advisory boards

  • Private, senior-level convenings

All engagements are scoped to deliver clarity, credibility and impact at speed.
