Tiers explanation: Natural capital can be measured in many different ways, by different users for different purposes. The NCMC allocates metrics and methods to three tiers, corresponding to different user needs and approaches to measurement, as summarised in the table below.

  • Verifiability, accuracy and costs tend to increase as you move from Tier 1 to Tier 3. 
  • Confidence/error tends to shift from unknown to quantified from Tier 1 to Tier 3. 
  • Ease of use and accessibility generally moves from easy through to challenging from Tier 1 to Tier 3.
