An Anthesis activation at Climate Week NYC 2025

At Anthesis, we guide organizations as they transition toward decarbonized and more sustainable futures. This September, during Climate Week NYC, we built an experience that reflects that mission—activating progress through bold ideas, practical solutions, and collective energy.

Our two-day activation was a space for momentum — where leaders convened, systems shifted, and the future took shape. We witnessed dynamic conversations, collaborative solutions, and bold action across climate, nature, and equity.

Future-Proofing Climate & Nature Action: Lessons from the Nexus of Water, Biodiversity, and Business Value 

Biodiversity and water are foundational business assets—indispensable to climate goals, supply chain and operational resilience, and long-term business growth. As climate change, ecosystem degradation, and water scarcity converge, forward-thinking companies are embedding nature action directly into their climate strategies to protect and grow enterprise value. 

Sustainability leaders from Ecolab and Diageo shared practical insights into how integrating biodiversity and water stewardship into climate action drives measurable returns.  They were joined by their implementing partners to share tangible examples of how implementing these strategies on the ground can further strengthen business resilience.

The Cost of Silence – Breakfast Panel with Freya Williams

As brands step up on climate, too many are stepping back on communications. The Cost of Silence — the latest research from Revolt (part of Anthesis) — shows that 79% of companies are inauthentic when communicating environmental performance.

The result? Missed opportunities for reputation, growth, and leadership.

In this candid conversation, Anthesis experts highlighted the real risks and opportunities for businesses when they choose silence on climate and sustainability — with Freya Williams and corporate leaders who are shaping the dialogue.

Regenerate to Accelerate: The Business Imperative for Climate & Nature Integration

As climate shocks, biodiversity loss, and supply chain volatility converge, regenerative agriculture has emerged as one of the most powerful levers to future-proof food systems and build resilience from soil to shelf.

This powerhouse panel of sustainability leaders from across the food and retail value chain met together for a dynamic conversation on the urgent need to scale regenerative agriculture across sourcing regions and landscapes. Featuring senior executives from Campbell’s and Kraft Heinz, this session went beyond strategy to explore tangible action: how companies are embedding nature and climate into unified approaches, mobilizing financing at scale, and working with farmers and partners to de-risk the transition to regenerative management systems.

Green Giants – 10-Year Anniversary Reception

A lively celebration of the 10-year anniversary of Freya Williams’ book Green Giants, reconnecting with the trailblazing brands it spotlighted and exploring what it takes to build the next generation of giants.

Green Giants: How Smart Companies Turn Sustainability into Billion Dollar Businesses profiled nine companies, from Tesla to Unilever, that proved sustainability and profitability could go hand in hand — building billion-dollar revenue streams around products, services, and business lines with impact at their core.

A decade later, it’s time to reflect on the first wave of Green Giants and ask: what will it take to build the next?
