Implications for EU citizens by 2050 | ca. 70 % reduction compared to 2008 | ca 45 % reduction compared to 2007d | ca. 90 % reduction compared to 2010 | (ca. 30–50 % reduction compared to 2004)e |

Rationale | Return to a global level of mineral extraction equivalent to the year 2000 (without considering erosion) | Halt the loss of biodiversity and keep land use change (LUC) within the safe operating space | Keep global warming within 2 degrees Celsius (67 % probability) | Scenarios based on potential efficiency improvements and demand-side reductions under four “One Planet” scenarios |
Calculation | Global total mineral extraction in the year 2000 divided by expected world population in 2050 | Max cropland area of 1.6 Mha divided by expected world population in 2030 | Global cumulative cap of 750 GtCO2(WBGU 2009); budget of 9.6 GtCO2 in 2050 divided by expected world population in 2050 | – |
Research needs | Link global resource extraction to social acceptance of impacts (e.g. as regardscriticality and pollution) | Develop targets for forests and pastures; better understand potentials for winning back abandoned land | Expand the target beyond the CO2 portion of the carbon footprint | Quantify a global target or explore possibility of regional targets that may be linked to global safe operating space |
