1. The problem asks for the reduction in fuel for Transport in Europe per person to match the global average, assuming proportions remain unchanged. 2. From the table, Europe's Ecological Footprint per person is 830,000 m² (or 830 in thousands m²). 3. Europe's proportion for fuel for Transport is 22%. 4. Calculate Europe's fuel for Transport per person: $$830 \times \frac{22}{100} = 182.6 \text{ (thousands m}^2) = 182,600 \text{ m}^2$$ 5. Calculate the global average fuel for Transport per person: - Total world population = 900 + 3900 + 830 + 350 + 135 + 550 = 6,665 million - Calculate weighted sum of fuel for Transport: Africa: $900 \times 43\% = 387$ Asia: $3900 \times 30\% = 1170$ Europe: $830 \times 22\% = 182.6$ North America: $350 \times 14\% = 49$ Oceania: $135 \times 36\% = 48.6$ South and Central America: $550 \times 44\% = 242$ - Sum = $387 + 1170 + 182.6 + 49 + 48.6 + 242 = 2079.2$ (thousands m² million people) 6. Global average fuel for Transport per person: $$\frac{2079.2}{6665} = 0.312 \text{ (thousands m}^2) = 312 \text{ m}^2$$ 7. Convert global average to m² per person: $$312,000 \text{ m}^2$$ 8. Calculate reduction needed for Europe: $$182,600 - 312,000 = -129,400 \text{ m}^2$$ This negative value indicates a miscalculation; re-check step 6. 9. Correction: The units in step 5 are inconsistent. The table values are in thousands m² per person, so multiply population by ecological footprint per person to get total footprint. 10. Calculate total fuel for Transport footprint per region: - Africa: $900 \times 11 \times 0.43 = 900 \times 4.73 = 4257$ (thousands m² million people) - Asia: $3900 \times 22 \times 0.30 = 3900 \times 6.6 = 25740$ - Europe: $830 \times 48 \times 0.22 = 830 \times 10.56 = 8765$ - North America: $350 \times 97 \times 0.14 = 350 \times 13.58 = 4753$ - Oceania: $135 \times 13 \times 0.36 = 135 \times 4.68 = 632$ - South and Central America: $550 \times 19 \times 0.44 = 550 \times 8.36 = 4598$ 11. Sum total fuel for Transport footprint: $$4257 + 25740 + 8765 + 4753 + 632 + 4598 = 44645$$ (thousands m² million people) 12. Total world population = 900 + 3900 + 830 + 350 + 135 + 550 = 6665 million 13. Global average fuel for Transport per person: $$\frac{44645}{6665} = 6.7 \text{ thousands m}^2 = 6700 \text{ m}^2$$ 14. Europe's current fuel for Transport per person: $$48 \times 0.22 = 10.56 \text{ thousands m}^2 = 10560 \text{ m}^2$$ 15. Reduction needed: $$10560 - 6700 = 3860 \text{ m}^2$$ 16. Approximate reduction is 4000 m² per person. **Final answer:** 4000 m²
