Green Lease
A commercial lease that includes provisions requiring landlord and tenant to cooperate on improving the environmental performance of a building, including energy efficiency, carbon reduction, and sustainability data sharing.
What is Green Lease?
A green lease incorporates environmental clauses into the standard commercial lease agreement. The Better Buildings Partnership (BBP) in the UK has published model green lease clauses covering energy management, waste, water, environmental management systems, and sustainability data sharing.
The split incentive problem — where landlords invest in building fabric but tenants pay energy bills — is a major barrier to commercial property decarbonisation. Green leases address this by creating shared obligations and mechanisms for cooperation. Typical clauses include: data sharing (tenant provides energy consumption data), operational management (agreed environmental performance targets), capital works (landlord commits to energy efficiency improvements), and fit-out standards (tenant meets minimum sustainability specifications).
Green leases are increasingly important for several reasons: MEES regulations require minimum EPC ratings for commercial lettings; institutional investors require ESG reporting across property portfolios; net-zero commitments necessitate Scope 3 reporting of downstream leased assets; and NABERS UK and similar rating schemes require operational energy data from tenants.
The BBP distinguishes between 'light green' leases (data sharing and cooperation clauses) and 'dark green' leases (binding performance targets with financial mechanisms). Most UK green leases currently sit at the lighter end of the spectrum.
Practical Examples
A REIT includes BBP-aligned green lease clauses in all new lettings, requiring tenants to share monthly energy consumption data and participate in an annual environmental review.
A corporate occupier negotiates a green lease that commits the landlord to achieving an EPC B rating within three years, with the tenant sharing the cost of energy efficiency upgrades through a service charge mechanism.
A fund manager uses green lease data sharing clauses to collect operational energy data from 200 tenants across its portfolio, enabling GRESB reporting and Scope 3 Category 13 emissions calculation.
How Climatise Helps
Climatise facilitates the data sharing that green leases require. Landlords and tenants can use the platform to report, share, and benchmark energy and emissions data — enabling compliance with green lease obligations and supporting portfolio-level sustainability reporting.
