Clear Haze Exchange

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.
