The climate plan itself (management, training, energy audit, incorporating carbon into purchasing) typically costs €20,000 to €80,000 excl. VAT in the first year for an SME, depending on size and scope.

Diag Décarbon'Action covers 40% of the assessment and plan cost, bringing the remaining cost to €6,000 excl. VAT for a first initiative.
