A net zero/carbon budget adjustment clause included as part of a completion accounts mechanism to provide “Carbon Certainty”.Skip to clause
Why use this?
Carbon footprints are not measured at completion, despite there being a cost of that carbon and corresponding ESG impact on the acquirer.
Once a business has achieved Net or Absolute Zero, it will be important for carbon budgeting to maintain and preserve that status.
A buyer who is Net Zero themselves will not want to acquire a business with an uncertain carbon footprint that will affect their overall Net Zero position. This is particularly the case if their finance is linked to ESG or Net Zero metrics.
In the same way completion accounts adjust for net assets, this clause adjusts for a net carbon position.
The drafting envisages that the buyer will use the overshoot amount adjustments to fund further offsetting or the transition to Net Zero.
How it promotes a net zero future
These clauses will ensure that carbon footprinting is embedded into a transaction and given equal importance with the net assets of the target.
The price adjustment mechanism will also incentivise companies to ensure their carbon position is optimised prior to completion as they would any other part of their business prior to a sale.
Purchasers will have ‘carbon certainty’ in their transaction, ensuring they keep within their carbon budget, emissions targets and ESG rules. This will help businesses in the race to zero.
The clauses will maintain the integrity of ‘transition capital’ used to finance the buyer, the fund or the transaction.
