在循环策略的帮助下，产品可以使用更长时间（即重复使用、维修和翻新）。难以使用的产品将被有效回收。本文提供了减少产品生命周期各个阶段对环境影响的可行指南，包括产品材料的制造和组装、使用过程中的环境影响、最终处置时的环境影响，以及具体行动和评估机制。循环经济是一个包含具体行动及其评估的概念。为了阐明循环经济对碳中和的贡献，本文强调了认识碳作为能源载体和材料的作用的重要性。二氧化碳是燃烧和驱动碳时产生的废物。二氧化碳必须像任何其他废物一样进行处理，但碳本身也是一种能量载体。因此，在促进碳循环时，协调碳作为材料的功能和作为能量载体的作用非常重要。可再生能源的进一步引入和社会向循环经济的转变将以相辅相成的方式有助于实现碳中和和更有效地利用资源。
With the help of circular strategies, products can be used longer (i.e., reuse, repair, and refurbish). Products that are difficult to use will be recycled efficiently. The present paper provides actionable guidelines for reducing environmental impact at all stages of a product’s life cycle, including the manufacture and assembly of the materials that make up the product, environmental impacts during use, and environmental impacts at final disposal, as well as specific actions and evaluation mechanisms. The circular economy is a concept that encompasses specific actions and their evaluations. To clarify the contribution of this circular economy to carbon neutrality, the present paper highlights how it is important to recognize the role of carbon as both an energy carrier and a material. CO2 is a waste product from burning and powering carbon. CO2 must be disposed of like any other waste product, but carbon itself is also an energy carrier. Thus, when promoting the carbon cycle, it is important to harmonize carbon’s function as a material with its role as an energy carrier. The further introduction of renewable energy and societal shift towards circular economy would contribute to carbon neutrality and more resource efficient use in a mutually complementary manner.
