This section provides a brief overview of the key arguments. It is not necessary to read the detailed report below.

✅ Key PRO arguments:

1. ■"Green design [8]" allows for substituting critical minerals [17] with more abundant alternatives, as illustrated by the development of LFP batteries [13] (Lithium [14] Iron Phosphate [10]) which completely eliminate cobalt [4] and nickel [18], thereby structurally reducing dependence on critical minerals.
2. ■Substitution is a form of "green design [8]" aimed at reducing reliance on metals whose supply is geopolitically risky or ethically problematic, such as cobalt [4], favoring more abundant metals, thus decreasing overall pressure on critical minerals [17].
3. ■Optimization of architectures during the design phase can reduce dependence on metals like cobalt [4] or lithium [14] by diverting massive flows of critical minerals [17] toward less rare substitute materials [16].

❌ Key CON arguments:

1. ■Material efficiency is overwhelmed by the quantitative explosion of the energy transition [23]: according to the IEA [1], global demand for lithium [14] is expected to increase by 40% by 2030, despite advances in high-energy-density batteries [6], which cancels out material reduction gains per unit of service.
2. ■Technical substitution merely shifts the mineral constraint rather than reducing it: replacing cobalt [4] with lithium [14] in LFP batteries [13] mechanically increases demand for another critical mineral, illustrating a simple transfer of pressure.
3. ■Design optimization cannot reverse a structural trend of multiplying units: the exponential growth of electric vehicles [24] and energy storage [21] offsets efficiency gains per unit, producing a rebound effect that maintains or even increases total demand.

💭 Conclusion: False: "green design [8]" methods and mineral efficiency standards [9] cannot drastically reduce demand for critical minerals [17]. The decisive argument is the quantitative rebound effect: the exponential growth in deployment of clean technologies (electric vehicles [24], stationary storage) generates an absolute demand that efficiency gains do not compensate for. The IEA [1] forecasts a 40% increase in global lithium [14] demand by 2030, directly contradicting the idea of a drastic reduction. Furthermore, material substitution (e.g., cobalt [4] replaced by lithium in LFP batteries [13]) merely shifts the constraint to other critical minerals without decreasing overall pressure. Finally, the distinction between displacement and reduction of mineral constraints is fundamental: "green design" reallocates demand rather than structurally lowering it.
