This report details the economic integration of the biophysical impact results of the JRC PESETA III project. Six impact areas have been fully integrated: labour productivity, river floods, coastal floods, energy, agriculture and human mortality due to heatwaves. A second objective of the economic task has been to explore the degree to which climate impacts cross geographical borders, the so-called spillover analysis. The global transboundary analysis has been made for the four sectors for which global impact estimates are available: labour productivity, river floods, energy, and agriculture. This document presents the methodology and main results of the economic assessment.
