A clause (which is revenue neutral for the Employer) requiring contractors and project delivery teams to use sustainable working practices on site in order to reduce the energy used in construction.Skip to clause
Why use this?
The clause seeks to drive engagement with existing industry standards and requires the parties to agree clear, specific practices at the outset that result in energy savings or other positive environmental impacts throughout the build phase.
The incentive is by way of a Green Retention Fund, which the contractor will be entitled to a distribution from on a sliding scale depending on the level of compliance it demonstrates throughout the works. The balance of any retention at practical completion will be distributed to an agreed climate-focused charity.
This means the clause is revenue-neutral for the employer.
How it promotes a net zero future
The aim is to entrench sustainable working practices in the industry. The climate crisis is often described as a large-scale, international issue which can dissuade smaller players from properly engaging. In contrast, issues that impact the local environment, to which individuals often feel they can more closely relate, can elicit more of a reaction.
By placing the onus on those actually delivering the works on site, individuals and companies are encouraged to take ownership for their climate impacts in their day-to-day work. Many construction companies now have green mandates and such a clause should ensure those mandates flow down to every project in which the company is involved.
