Who We Work With

ISG works with organisations that are serious about making a meaningful difference in the world.

We partner with leaders who recognise that climate and other systemic challenges are real, urgent and complex, but not insurmountable. Our clients engage seriously with evidence, value scientific insight, and are prepared to act on what it shows.

Our approach to partnership

We work with organisations that approach complex challenges thoughtfully, constructively and with intent.

Our partners recognise the scale of climate and systemic risk, value independent and evidence-grounded insight, and are open to what that evidence implies for strategy and action. We prioritise long-term impact over short-term expediency, and integrity over convenience.

This approach allows us to support leadership teams seeking decisions that stand up over time.

We support organisations across sectors where leadership decisions are shaped by climate risk, policy change and growing public scrutiny, including:

  • Boards and executive teams navigating climate and transition decisions

  • Investors and financial institutions assessing long-term risk and credibility

  • Mission-driven corporates seeking to lead responsibly and competitively

  • Foundations and public-interest organisations focused on real-world impact

  • Public sector and policy actors engaging seriously with evidence
