The New Fault Line: How U.S. Polarisation Is Reshaping Global Sustainability with Gillian Tett and Professor Bob Eccles

The U.S. has become the centre of a global sustainability fault line: it hosts the world’s most advanced innovation ecosystem and deepest pools of private capital—yet remains locked in intensifying political polarisation, regulatory rollbacks, and an anti-ESG backlash. These tensions are reshaping climate policy, capital flows, and global markets.

To understand this moment, Lindsay Hooper and Marc Kahn speak with two globally respected interpreters of political economy and corporate purpose:
Gillian Tett, Provost of King’s College Cambridge and acclaimed FT journalist, and Professor Bob Eccles, leading thinker on corporate reporting and political consensus-building. Together they explore how the U.S. arrived here, how companies are responding on the ground, what this means for global action, and how leaders can navigate the fragmented landscape.

Key Quotes
“Most people aren’t extreme. They’re exhausted. The challenge is creating a narrative that speaks to the middle again.” — Bob Eccles

“Many companies are simply carrying on as before; the rhetoric has changed more than the practice.” Gillian Tett

Key Takeaways
1. Despite the political backlash, most companies continue advancing sustainability quietly because the underlying economic and risk drivers remain strong.

2. The real divide is not left versus right, but public rhetoric versus on-the-ground reality, where pragmatic climate action is still progressing.

3. Reframing sustainability through language around nature, resilience, stewardship and cost savings can rebuild common ground.

4. Leaders must clearly separate material value creation from virtue signalling to regain trust and reduce polarisation.

5. Adaptation and shared local impacts offer a unifying entry point that resonates across political and social divides.
