Four programmes, each counted the way its claim says it was counted. Where a number did not hold up, that is in the file too.
Mixed native planting, counted on the ground at year three rather than at the moment of planting. The eighteen per cent that did not take is in the file too.
On-site generation and power purchase agreements replacing grid supply, metered at each site rather than apportioned from a single group figure.
Material flow mapping and supplier redesign, with every tonne weighed as it leaves the gate instead of estimated back from purchase invoices.
A contract read line by line before it was signed, with the additionality argument written down rather than assumed from the certificate.
