Significant amounts of feedstock metals will be required to build the infrastructure for the green energy transition. It is currently estimated, however, that the world may be facing an "infrastructure gap" that could prevent us from meeting United Nations Sustainable Development Goal targets. Prior investigations have focused on the extractive aspects of the mining industry to meet these targets and on looming bottlenecks and regional challenges in these upstream market segments. Scant attention has been paid to the downstream processing segments of the raw materials value chain, which also has a high degree of market concentration. Growing international tensions and geopolitical events have resulted in a shift toward "reshoring" and "near-shoring" of mining processing capabilities as regional powers attempt to make metal supply chains more secure. While increasing resilience, these shifts can also dilute the overall effectiveness of the global mining supply network and subsequently hamper the world's ability to close the green energy infrastructure gap. We argue that broadening the remit of the International Renewable Energy Agency (IRENA) to include coordinating these mission-critical metal processing functions can mitigate these issues. The G20 is one potential forum for enabling an integrated mineral processing agreement under the auspices of IRENA.
为实现绿色能源转型而构建基础设施,需要大量的原料金属。然而,据目前估计,世界可能面临“基础设施缺口”,这可能会阻碍我们实现联合国可持续发展目标。先前的调查主要集中在矿业的开采方面,以实现这些目标,以及这些上游市场环节迫在眉睫的瓶颈和地区挑战。对于原材料价值链的下游加工环节,关注甚少,而该环节的市场集中程度也很高。国际紧张局势和地缘政治事件不断加剧,导致各国纷纷寻求“回迁”和“近岸回迁”采矿加工能力,因为地区大国试图使金属供应链更加安全。虽然这些转变提高了韧性,但也会降低全球采矿供应链的整体有效性,从而阻碍世界缩小绿色能源基础设施缺口的能力。我们认为,扩大国际可再生能源机构(IRENA)的职权范围,以包括协调这些关键任务的金属加工职能,可以缓解这些问题。G20 是在 IRENA 主持下达成综合矿产加工协议的一个潜在论坛。
