For buyers · WRC price index
A reference price for every certified cubic metre.
Water certificates trade over the counter and prices stay private. The WRC index will publish ranges built on real transactions.Price ranges, built on real transactions.
02Why an index
Without a reference price, everyone negotiates blind.
Guarantees of origin and voluntary carbon credits have independent price assessments. Water certificates need one too.One shared reference for three trades.
- Buyers Budget a water programme on a public range.Budget on a public range.
- Project developers Set a price that holds up with buyers.Set a defensible price.
- Funders Value future certificates in a financing plan.Value future certificates.
03What the index separates
A cubic metre is not worth the same everywhere.
Just as a guarantee of origin is priced by technology and vintage, a water certificate reads by segment. These are the criteria of the fee simulator.The criteria of the fee simulator.
- Protocol The project type: leaks, reuse, aquifer recharge…The project type.
- Evidence tier T1 instrumental measurement, T2 third-party record, T3 conservative modelling.T1 to T3.
- Basin stress From T1, unstressed, to T5, extreme stress. It informs the price, never the certified volume.T1 to T5, no effect on volume.
- Vintage The year the water was saved or returned.The year of the action.
04Method
Real transactions, a public method.
The index starts from registry transactions and those reported by the panel. It publishes a range, never a single quote.Real transactions, a published range.
