Assessment of Europe’s environmental footprint based on planetary boundaries

The study assessed whether Europe’s

environmental footprints are within

the ‘safe operating space’ defined by

the planetary boundaries framework by

using a ‘basket’ of allocation approaches.

It explored the implications of using

four allocation principles proposed

in the context of climate negotiations

(e.g. Höhne et al., 2014), in addition to the

equality principle:

Needs: people’s different resource needs

due to age, household size, location of

residence.

Rights to development: resource needs

proportional to development level (more

resources to less developed countries to

enable them to meet their development

objectives).

Sovereignty: resource needs as a function

of economic throughput, biocapacity and

land availability.

Capability: resource needs according to

wealth and financial capability.

The principle of sovereignty results in the

highest European share of the global safe

operating space (median of 12.5 %), while

the principle of rights to development

results in the lowest share (median of

4.1 %). The yellow range in Figure 1.9

represents the average range across the

five allocation principles, with a median

of 6.9 %. This yellow range is defined as

the ‘zone of uncertainty’ to reflect the

normative process of defining a European

safe operating space.

This basket of allocation approach

has been tested at the European scale

with consumption-based footprint

data (Exiobase, version 3) for three

planetary boundaries: (1) land system

change; (2) biogeochemical flows

(phosphorus, nitrogen, addressed

separately); and (3) freshwater use.

The results largely confirm the findings

from Häyhä et al. (2018). European

transgressions are substantial for

phosphorus and nitrogen, regardless of

which allocation principle is used. The

land boundary is transgressed when

applying the equality, needs, rights to

development and capability principles

but not when using the economically

determined sovereignty principle (not

seen in the averaged yellow range in

Figure 1.9). The freshwater boundary is

not transgressed in Europe as a whole,

regardless of which allocation principle

is applied. However, this does not mean

that there are not severe regional water

issues, especially in southern Europe. ■

Notes:

The yellow zone of uncertainty represents the average range across the six principles to allocate a European share of the global safe

operating space.

The study takes a conservative approach, as it calculates the European share based on the lower end values of the global zone of

uncertainty defined by Steen et al. (2015). For example, the global zone of uncertainty for freshwater is defined as 4 000-6 000 km 3 in

Steffen et al. (2015). This study uses 4 000 km 3 as the basis for calculating the European share. In some cases (indicated in brackets)

slightly different control variables have been used than in Steffen et al. (2015).
