Definition – Complementarityinfo-icon refers to a beneficial situation where the implementation of two measures results in greater total benefits than the implementation of either measureinfo-icon on its own:

  • Benefits (A+B) > Benefits gain A, and
  • Benefits (A+B) > Benefits gain B.

These total benefits may result across different policyinfo-icon sectors (e.g. environmentinfo-icon, health), as a result of horizontal integrationinfo-icon informing measure selection. See also synergies.

Relevance to SUMP – Careful measure selection during the SUMP development process can help to ensure the greatest possible benefit to all by looking for opportunities for complementarity and synergyinfo-icon.
