  • Carbon Circle Ep.14 - Turning #cbam into a Competitive Advantage
    Feb 23 2026

    From Compliance to Strategy: Turning CBAM into a Competitive AdvantageReimagining Global Trade Through Carbon — The CBAM Revolution with Marcel Duits🎙️ Episode SummaryAs carbon pricing reshapes global trade, businesses can no longer afford to treat compliance as a checkbox exercise. The real question today is: Can climate regulation become a competitive advantage?In this episode of The Carbon Circle Podcast, host Roshan Rai, Founder of Carbon Mandal, sits down with Marcel Duits, Chief CBAM Officer at Dubrink, to unpack one of the most consequential climate policies of our time — the European Union’s Carbon Border Adjustment Mechanism (CBAM).Drawing from real-world experience supporting over 2,000 companies, Marcel explains how CBAM is transforming supply chains, pricing models, and sourcing decisions across industries like steel, aluminium, and cement.From the origins of CBAM to its complex calculation methods, rising ETS prices, and looming 2026 authorization deadlines, this conversation reveals why companies that act early can protect margins, reduce risk, and unlock long-term strategic value.This episode goes beyond compliance to explore how verified emissions data, supplier engagement, and digital tools can turn regulatory pressure into a powerful business opportunity.If you’re involved in international trade, manufacturing, sustainability, or ESG strategy, this conversation is essential.📘 What You’ll Learn🌍 What CBAM is, why it was created, and how it’s reshaping global trade flows📊 How CBAM charges are calculated — and why default values can destroy margins💶 The real cost impact of rising ETS prices on imported materials🏭 Why verified emissions data can be worth hundreds of euros per ton⏳ Key timelines, authorization risks, and upcoming compliance bottlenecks🔄 How companies are redesigning supply chains to stay competitive📈 Where smart businesses are finding margin opportunities under CBAM🌐 Why CBAM could trigger a global “carbon pricing domino effect”🌐 Useful LinksCarbon Mandal – Official Websitewww.carbonmandal.comConnect with Marcel Duitshttps://www.linkedin.com/in/marcelduits/Dubrink Website: www.dubrink.com🤝 Collaborations, Consulting & PartnershipsFor partnerships, collaborations, Life Cycle Assessment (LCA) projects, sustainability consulting, or to feature on The Carbon Circle Podcast, reach out to:📩 contact@carbonmandal.com🔖 KeywordsCBAM regulation, carbon border adjustment mechanism, EU climate policy, carbon pricing, ETS price impact, sustainable supply chains, ESG compliance, global trade decarbonization, climate regulation strategy, carbon markets Europe, green trade policy, Carbon Mandal podcast📌 Hashtags#CBAM #CarbonPricing #SustainableTrade #ClimatePolicy #ESGStrategy #Decarbonisation #GlobalTrade #CarbonMarkets #TheCarbonCircle #CarbonMandal #ClimateLeadership #GreenEconomy

  • Carbon Circle Ep 9. Why Fixing #waterwaste is the Fastest Way to Netzero #watercrisis #climatetech
    Feb 23 2026

    🌊Turning Evaporation into Innovation: India's Water-Energy-Carbon NexusWater is the most overlooked element in India's climate crisis. While corporations chase net-zero carbon, the massive water waste in industrial cooling towers—consuming up to 60% of a facility's water budget—remains an invisible blind spot.In this powerful episode of The Carbon Circle Podcast, we dive into the critical, yet often ignored, Water-Energy-Carbon Nexus that will define India's path to Sustainable Bharat 2047.Join Host Roshan Rai as he speaks with Rishi Vandhan, CEO AND co-founder of Earthfokus, a climate-tech company pioneering a patent-pending mechanical system that can reclaim around 40% of evaporated water from cooling towers. Rishi, who transitioned from a high-flying career in corporate finance (Goldman Sachs, Big 4) to climate entrepreneurship, offers a unique perspective on why water conservation is the biggest untapped leverage point for both energy reduction and carbon footprint control in industrial India.This conversation moves beyond compliance to explore a fundamental shift: how to turn water recovery into a continuous, visible operational reality and a competitive advantage in a water-scarce nation.🧠 What You’ll Learn:🌊From Everest to Entrepreneurship: Rishi's personal journey from corporate finance to co-founding a water-tech company and how it reflects India's shift toward sustainability as a primary professional identity.🌊The Water Blindness Crisis: Why water remains invisible in corporate sustainability strategies and how ignoring water waste in cooling towers undermines net-zero energy goals.🌊The Cooling Tower Opportunity: The economics behind Earthfokus's mechanical water recovery system and why market-specific innovation works where global, energy-based solutions fail in India.🌊Water Security and AI: How cooling tower efficiency is becoming a geopolitical question—enabling India's digital future (AI Data Centres) while protecting its critical water resources.🌊Consciousness as Lifestyle: Earthfokus's philosophy of measuring success through sustained behavioural change and using daily habits (like handwashing) as a gateway to water consciousness.🌊Building Sustainable Bharat 2047: How water recovery can move from a compliance checkbox to a standard industrial practice, attracting tech investment and safeguarding India's water security.🌐 Earthfokus: https://earthfokus.com/🌐 Rishi Vandhan: https://www.linkedin.com/in/rishi-vandhan/📩 For collaborations, sustainability consulting, or to join The Carbon Circle, reach us at connect@carbonmandal.com 🌐 Carbon Mandal: https://www.carbonmandal.com🔖 Keywords #waterconservation , #coolingtowers #Earthfokus, #Water-Energy Nexus, #carbonreduction #carbonmandal #sustainablesolutions @mybharatgov SustainableBharat2047 , #watersecurity #climatetech #india #industrial #water #ESG #ClimateEntrepreneurship #mechanicalinnovation , #datacentre
