Adaptation Cost Curves

Adaptation Cost Curves (ACCs) have been proposed as a tool to assist decision-makers in understanding adaptation options in terms of costs and benefits. ACCs are obtained by plotting the cost-benefit ratio as a function of the averted loss (benefit) for each adaptation measure. Thus, in order to generate ACC, a set of key quantities is necessary, namely, theexpected loss, the averted loss (the residual loss is given by the expected loss minus the averted loss), and the adaptation costs.

This report gives a critical but constructive re-inspection of ACCs. Based on the previous work done in RAMSES WP5 and WP1, various detailed ACCs are provided for the RAMSES focal case studies. Additionally, costs and benefits have been analyzed in a standardized top-down approach for more than 100 European cities.
