    Your Waste Is Telling You Something: Rethinking the Circular Workplace | Hélène Carpentier

    What if your organization’s waste problem actually starts long before anything reaches the trash bin? In this episode of Clear Haze Exchange, Marcus Hazelwood sits down with Hélène Carpentier, Founder of Circular Workplaces and former Global Head of Circular Economy and Zero Waste at CBRE, to rethink how organizations approach waste. Hélène challenges one of the most common assumptions in workplace sustainability: that better recycling is the answer. Instead, waste can be a signal of something happening much further upstream, over-purchasing, inefficient procurement, disconnected workplace systems, and resources that were paid for but never fully used. The conversation explores: • Why recycling alone can’t solve the waste problem• How procurement decisions determine much of what eventually becomes waste• The hidden cost of waste beyond disposal fees• Why food, packaging, and everyday workplace purchases deserve more attention• How waste reduction can improve the workplace experience• Why sustainability teams, procurement, facilities, and workplace teams need to work together• How organizations can shift measurement from downstream diversion to upstream prevention Hélène also shares a striking example of how a 2,000-person workplace could lose more than £1.6 million over five years through waste-related inefficiencies, much of it potentially avoidable. The takeaway? Waste isn’t just something to manage at the end. It’s information. And if organizations pay attention to what it’s telling them, they may uncover opportunities to reduce cost, carbon, and inefficiency while creating better workplaces. 🎧 Listen to Clear Haze Exchange on Apple Podcasts, Spotify, or wherever you get your podcasts. ▶️ Watch the full conversation on YouTube.

    Why Great Energy Projects Never Happen (And How ESPCs Change That) | Chris Halpin

    Most organizations don't struggle because they lack opportunities to improve their buildings. They struggle because they don't know how to fund, structure, and manage those improvements. In this episode of Clear Haze Exchange, Marcus Hazelwood sits down with Chris Halpin, President of Celtic Energy and one of the nation's leading experts in Energy Savings Performance Contracting (ESPC).  Having supported more than $2.5 billion in energy infrastructure projects across federal, state, and institutional markets, Chris explains why performance-based delivery continues to create value decades after it was introduced. Topics include: • Understanding Energy Savings Performance Contracting • Why many organizations hesitate to pursue ESPCs • Risk allocation and financial accountability • The value of owner's representatives • Measurement & verification beyond compliance • Long-term operational thinking vs. first-cost decisions • Resilience as the next evolution of energy investments • Why education is essential before projects ever begin Key Takeaway Buildings don't become high-performing simply because new equipment is installed. They become high-performing when owners understand how to operate, verify, and sustain those investments over time. Chris mentioned several excellent organizations and resources for those interested in learning more about Energy Savings Performance Contracting (ESPC), building performance, and public-sector energy projects: - U.S. Department of Energy – Better Buildings Initiative - National Association of State Energy Officials (NASEO) - National Association of Energy Service Companies (NAESCO) - Energy Services Coalition (ESC) Subscribe for more conversations uncovering the hidden systems behind sustainability, energy, and building performance.

    Networks, Data & The Future of Net Zero with Sarah Merricks

    What if the biggest barrier to achieving Net Zero isn't technology, policy, or even funding? What if it's fragmentation? In this episode of Clear Haze Exchange, Marcus Hazelwood sits down with Sarah Merricks, Co-Founder and Chief Strategy Officer of Global Network for Zero (GNFZ), to discuss why the future of decarbonization depends on building stronger networks supported by transparent, measurable data.  Sarah draws from her experience helping expand LEED globally during her time at USGBC and now helping organizations navigate the complexities of Net Zero through GNFZ. This conversation explores:  Why the Net Zero movement remains fragmented globally  Scope 1, 2, and 3 emissions explained  Why Scope 3 remains one of the biggest challenges organizations face  Why existing buildings need a different approach  The power of data-backed decision making  How networks accelerate progress  Why implementation now matters more than pledges  How different countries are approaching decarbonization Key Takeaway: Data creates clarity. Networks create momentum. As Sarah explains, organizations shouldn't ask: "What is everyone else doing?" They should ask: "What does our data tell us is urgent and achievable?" 🎧 Available now on Apple Podcasts, Spotify, YouTube, Amazon Music, and all major podcast platforms. 👉 Subscribe to Clear Haze Exchange for weekly conversations exploring the hidden systems shaping sustainability decisions.

    Green Leases, Decarbonization & The Hidden Influence of Tenants with Jon Lemmond

    Most sustainability conversations focus on building owners. But what about tenants? In this episode, Marcus Hazelwood sits down with Jon Lemmond of JLL to discuss how tenants can influence building performance, energy efficiency, and decarbonization outcomes, even when they don't control the building's major systems. From New York City's Local Law 97 to green lease structures, submetering, shared investment strategies, and landlord-tenant collaboration, Jon explains how organizations can unlock sustainability opportunities that are often hiding in plain sight. The conversation explores why communication, measurement, and aligned incentives may be more important than any individual technology. In This Episode:  Why decarbonization efforts often stall in leased spaces  The "split incentive" challenge between landlords and tenants  How green leases can create shared financial and environmental value  Why submetering and data transparency matter  Local Law 97 and the rise of building performance standards  Tenant strategies for reducing Scope 1, 2, and 3 emissions  How leasing decisions influence long-term building performance  Why communication may be the most powerful sustainability tool available Key Takeaway Many tenants assume they have little influence over building performance. The reality is often the opposite. The organizations achieving the best outcomes are the ones engaging landlords early, aligning goals, sharing data, and treating sustainability as a partnership rather than a requirement.  🎧 Subscribe to Clear Haze Exchange on Apple Podcasts, Spotify, YouTube, Amazon Music, and all major podcast platforms.
