Decarbonizing global apparel supply chains is one of the industry's greatest sustainability challenges. With most emissions occurring beyond the direct control of apparel brands, achieving meaningful reductions requires more than technology and climate commitments. It requires commercially viable solutions, stronger supplier partnerships, and new approaches to financing.

In this episode of the Sustainable Ambassador Podcast, Dr. Thiwanka De Fonseka, Chief Sustainability Officer at Komar, explores the complexities of apparel supply chain decarbonization and what it will take to accelerate progress.

Drawing on his experience, Thiwanka discusses how brands can prioritize emissions reductions, integrate sustainability into sourcing decisions, and create the commercial incentives suppliers need to invest. We also explore the importance of sharing costs and risks, unlocking financing, and fostering industry collaboration to make decarbonization commercially viable at scale.

In this episode of the Sustainable Ambassador Podcast, I speak with Professor Tim Palmer, a climate physicist at the University of Oxford, about why we need better climate models to improve climate prediction, deepen our understanding of regional climate change impacts, and help governments, businesses, and communities make better-informed decisions about the future.

Drawing on his recent article in The Economist, "The World May Have Less Time Than It Thinks on Climate Change," Tim explains why understanding global warming is relatively straightforward, but predicting how climate change will influence atmospheric circulation, droughts, monsoons, and extreme weather events remains extraordinarily complex.

We explore the scientific and computational challenges holding back climate modeling, why greater international collaboration and pooled resources are needed to develop more sophisticated models, and how improved regional predictions could fundamentally change the way governments, businesses, and communities prepare for climate risks.

Throughout the conversation, Tim emphasizes that alongside reducing emissions and investing in adaptation, we must strengthen the science and modeling capabilities that underpin those decisions. Better climate models can provide more reliable regional predictions, helping decision-makers understand the risks they face, prioritize investments, and prepare more effectively for a changing climate.

As the world moves closer to exceeding the Paris Agreement's 1.5°C warming threshold, UNEP's big climate shift from mitigation alone toward greater emphasis on adaptation and resilience signals a fundamental change in how we approach climate action.

What does this mean for governments, businesses and communities preparing for a warmer world? In this episode, Rich speaks with Mirey Atallah, Chief of the Adaptation and Resilience Branch at the United Nations Environment Programme (UNEP), about the recently released report Limiting Overshoot: Navigating Exceedance of 1.5°C and Pathways Towards Return.

Mirey explains why the report signals an important shift in climate strategy—from focusing primarily on preventing warming beyond 1.5°C to also preparing for, managing and shortening the period of overshoot. They explore the implications for mitigation, adaptation, climate finance and long-term policymaking, particularly in the Global South.
