As Earth Day 2025 approaches on 22^nd April, the call for collective action on sustainability grows even louder.

This year’s theme, OUR POWER, OUR PLANET, underscores the urgent need to transition to renewable energy sources and triple global clean electricity generation by 2030. Through education, advocation, and mobilisation, the initiative is intended to bring together individuals, organisations, and governments to address the pressing environmental challenges we all face. ​

Integrating sustainable practices through ESG has gained significant traction and delivered measurable benefits for businesses, though not without its share of critics. Corporate responsibility remains a vital and evolving topic of debate among business leaders and policymakers alike. To navigate this complex landscape, insights from seasoned sustainability experts are invaluable.

Few understand the complexities of capital and climate better than Financial Times journalist Simon Mundy. His reporting — from Seoul to São Paulo — reveals the complex trade-offs involved in the global sustainability race. In contrast, sustainability scientist Mike Berners-Lee takes a grounded, numbers-first approach. His work shows that while no action is perfect, the cost of inaction is immense — and measurable.

Meanwhile, pragmatism remains essential. Stuart Kirk, known for his frank critique of ESG orthodoxy, reminds audiences that financial markets follow value, not virtue. While provocative, his perspective injects urgency into the debate: if sustainability is to endure, it must prove its economic resilience.

Rosalind Kainyah brings decades of experience helping multinational firms embed responsible practices in high-growth markets. Her approach reflects a belief that ESG must be more than branding — it must be built into the bones of corporate strategy.

Equally influential is Alok Sharma, whose presidency of COP26 underscored the vital role of diplomacy and finance in forging climate commitments. He’s helped steer global consensus in a fractured geopolitical landscape — a reminder that progress is possible, but never guaranteed.

On the consumer front, Joanna Yarrow brings sustainability to life through design and behaviour change. Previously the Global Head of Sustainable & Healthy Living for IKEA, she focuses on making sustainable living appealing and accessible through strategic communication.

In light of Earth Day, engaging with these thought leaders can provide organisations with the knowledge and inspiration needed to advance their sustainability agendas. Their collective expertise offers a holistic foundation for meaningful discussions on achieving a sustainable and equitable future.
