According to the World Green Building Council “the greenest building is the one that is already built.” This is why a property’s environmental impact and sustainability credentials are so important for businesses of all sizes and why the Government has published a schedule for raising minimum EPC ratings for commercial properties.
While it remains true that the design of new builds does help to address a property’s greenhouse gas (GHG) emissions, as most of UK property stock already exists, their energy credentials can only be improved retrospectively.
This is why green leases have a significant role to play in any decarbonisation strategy. The incidence of landlords and tenants collaborating to reduce the environmental impact of occupying a property, while enhancing the value of their investment in the building, is growing in frequency.
There is not yet a legal requirement in the UK to enter a green lease, however there are pieces of legislation which impose energy efficiency requirements to ‘green’ the ownership and occupancy of a commercial building, such as the MEES regime. The definition of a green lease, sometimes referred to as a sustainability lease, remains loosely defined. However, they can be characterised as one or more clauses in a lease which commit landlords and tenants to work together to improve the environmental credentials of a building, ‘futureproof’ their properties by anticipating potentially stricter environmental laws and policies and save money by reducing the building’s carbon footprint.
The gradual increasing level of adoption of green lease clauses has been driven by the mutual benefits they provide owners and occupiers. These might include energy efficiency, waste reduction, water efficiency, recycling and waste management, data and intel sharing, which is especially popular in multi-occupancy buildings used by more than one occupier or lessee and/or the use of sustainable materials during a refurbishment or retrofit.
In an age of escalating energy costs, energy efficient buildings represent another incentive for landlords to reduce occupational costs by ensuring that their properties have as little energy waste as possible. Investing in ‘greening’ buildings, by ensuring they meet and exceed existing and impending standards, enables landlords to command higher rents and encourage tenants to stay longer.
Working together
Building provisions into contracts right from the outset encourages tenants and landlords to work together to invest in sustainable initiatives, which both parties benefit from. Today, tenants actively discriminate in favour of high-spec offices, with environmental standards high amongst their priorities.
Improved green credentials make buildings more efficient to run, more attractive to an increasingly environment conscious workforce and help demonstrate a business’s commitment to sustainability.
For example, a growing number of tenants, especially in the industrial sector, have opted to install solar panels to improve their net zero credentials. The investment is quickly recouped from the savings in energy bills, while landlords see their buildings enhanced at no cost: a win-win outcome.
In recent months, greater clarity has emerged in respect of green leases, as they grow in popularity. There are three broad categories of green leases:
- Light green leases require only a limited commitment from both parties and are generally notlegally binding
- Medium green leases feature limited obligations on both parties but stops short of imposing any financial burden
- Dark green leases are legally binding and require significant commitment to sustainability
Green clauses continue to develop in response to developments in monitoring and building management technology, as well as legislative changes.
Green leases can enhance real estate portfolio values through both perceived and tangible benefits. They improve marketability by attracting sustainability-minded tenants and strengthening ESG credentials, which can boost a property’s appeal to investors. In practical terms, they often lead to operational cost savings, ensure compliance with tightening environmental regulations, and can support higher rents and increased asset values.
Additionally, they may unlock access to green financing or other incentives. The extent of the value uplift depends on careful drafting, market demand for sustainable buildings, and the measurable environmental performance of the property.
It is no wonder then that despite being introduced less than 20-years ago, green leases are growing in popularity in London as an integral part of a wider sustainability mix.
