利用可再生能源实现零排放：铝业

铝支持从包装和汽车到电缆和设备的广泛应用，以及其他关键应用。铝的多功能性是由于其强度高、重量轻、可回收性以及优良的电导率和导热性。此外，铝在促进能源转型方面发挥着至关重要的作用，从用于太阳能电池板和风力涡轮机，到电动汽车和传输电缆。然而，在铝生产中使用化石燃料——主要是煤——导致了工业过程排放的显著增加。2022年，铝行业产生了约11亿吨当量的二氧化碳排放。铝生产的排放主要取决于电力结构；使用水力发电等可再生能源的冶炼厂比依赖化石燃料的冶炼厂排放更少。在过去的几个月里，随着全球变暖的加剧和全球变暖的加剧，全球变暖对全球变暖的影响越来越大，全球变暖对全球变暖的影响越来越大。本报告旨在向铝行业和政策制定者提供信息，说明如何通过整合更高比例的可再生能源和其他去碳化措施，如中性极、回收利用以及材料和能源效率，最大限度地减少排放。

Aluminum supports a wide range of critical applications spanning packaging, automotive, cables, equipment, and other sectors. The versatility of aluminum stems from its high strength-to-weight ratio, excellent recyclability, and superior electrical and thermal conductivity. Furthermore, aluminum plays a pivotal role in advancing the global energy transition, from solar panels and wind turbines to electric vehicles and power transmission cables. However, the use of fossil fuels—primarily coal—in aluminum production has led to a significant increase in industrial process emissions. In 2022, the aluminum industry generated approximately 1.1 billion tonnes of CO₂ equivalent emissions. Emissions from aluminum production are primarily dependent on the power mix; smelters using renewable energy sources such as hydropower produce far fewer emissions than those reliant on fossil fuels. In the past few months, as global warming has intensified and intensified, the impact of global warming on global warming has grown increasingly large, and the impact of global warming on global warming has grown increasingly large. This report aims to inform the aluminum industry and policymakers on how to minimize emissions by integrating a higher share of renewable energy and other decarbonization measures, such as carbon neutrality, recycling, as well as material and energy efficiency.
