Drafting notes

An overage clause is generally included in a commercial property or land sale contract by the seller so that the seller is entitled to receive additional funds post-completion if a ‘trigger event’ takes place.

In this case, the trigger event is the buyer’s failure to meet the net zero objectives (as defined) post-completion.

Rory’s Clause (Net Zero Land Promotion Agreement) uses this definition to:

  1. discourage buyers from failing to meet the net zero objectives set in the sale agreement; and
  2. allow landowners to influence the climate impact of a development.

Option 2

If using this definition, consider which of the net zero objectives need to be included in your agreement and tailor the menu accordingly.

Application

Real estate contracts in general, contracts between landowners and their promoters/ developers, purchase and sale agreements, principles for landowners/ promoters/developers.
