Wallacea Trust
Wallacea Trust pioneered the basket-of-metrics approach to biodiversity credits, defining a credit as a measurable percentage uplift or avoided loss in biodiversity per hectare across a basket of habitat-relevant indicators.

The basket-of-metrics approach, modelled on the retail price index, requires a minimum of five measurable metrics that reflect national and local conservation objectives for a given habitat.
A biodiversity credit is defined as a 1 percent uplift or avoided loss per hectare, measured as the median percentage change in the basket against a reference site, with the basket measured at project initiation.
It is widely described as the most-adopted independent biodiversity-credit methodology, with version 3 of the method published in October 2023.
A methodology for biodiversity projects measured by a basket of metrics, giving each credit a verifiable evidence trail.
