Figure 7. Visualization of challenges to the use of various footprint concepts (FPi): (1) consistency checks between individual and national footprints across production and consumption; (2) accountability for emissions embodied in trade (EET); (3) incorporation of (avoided) impacts on sink strengths, e.g., based on pollution; (4) the indirect land-use change concept; and (5) further attribution issues in relation to multifunctional land uses.
