Download the CLIMATE SCRUTINY Guide to CCIA.

At the heart of CLIMATE SCRUTINY is an understanding of the implications of climate change for the net benefits generated by the policy. There is now a growing library of work that applies Climate Change Impact Appraisal (CCIA) to policies and projects in each of the main sectors affected by CC. This work aims to build on existing practices for policy/programme appraisal and to ask the question: what are the net benefits without taking CC into account and how do these change when CC is taken into account. CCIA uses the CC% indicator, defined as (B-A)/B, where B = the net benefits with CC and A = the net benefits without.

CCIA can be done at five different levels

  1. Screening: by reference to a few key questions and criteria
  2. Classification: by reference to a table providing international norms for CC%
  3. Rapid qualitative CCIA: carefully structured to retain objectivity
  4. Hybrid CCIA: incorporating the best features of qualitative and CBA
  5. CC Sensitive Cost Benefit Analysis (eCBA): with full valuation and covering economy, society and environment
