* Max-impact - we need a good estimate for the maximum CO<sub>2</sub> impact, i.e. the largest possible distance. For European countries that can be a distance from a country in the pacific ocean.

* Max-impact - we need a good estimate for the maximum CO<sub>2</sub> impact. You would expect that getting something from an island in the Great Ocean (20.000km away) would have the most impact, but is better than transporting something from Greece to France by truck. We set the maximum impact at the largest distance by maritime mode. This might punish road transport as well.
