减少碳足迹的最新产品
蔡司聚酰胺太阳镜
强烈的环保意识促使蔡司 Sunlens 通过改进生产设施和使用可再生资源,
开发出一种可持续认证聚酰胺平光太阳镜片。
其结果是减少了产品的二氧化碳排放量,
这一改进在整个价值链中都得到了独立机构的认证。

减少碳足迹的生产流程
两个主要的可再生因素有助于减少制造镜片的二氧化碳排放量:
1. 使用质量平衡的生物基材料
2. 购买可再生电力
在镜片生产过程中,40% 的生物原料(来自农业生产的废料)在整个价值链中部分替代了化石原料,并 100% 使用可再生电力。
与完全使用化石燃料的制造工艺相比,该镜头的碳足迹减少了 50%。*
*该声明指的是 "从摇篮到终点 "系统,包括所有上游活动,以及意大利生产基地与聚酰胺镜片/防护罩/护目镜制造相关的所有流程。评估中不包括报废(镜片处理)产生的全球变暖效应。
关于意大利生产厂生产的可持续聚酰胺镜片,已采用 ISO14067:2018 温室气体排放计算规则,并使用了生命周期清单阶段(收集过程输入和输出数据)的最新可用数据(2020 年 10 月至 2021 年 9 月),其中包括生物碳固存价值链中的影响。
我们对地球的贡献
国际认证证明了蔡司对环境的重视和承诺
蔡司太阳镜片秉承着严谨的态度,希望整个生产链都能通过 REDcert² 标准(化工业可持续材料认证系统)的认证。这款质量平衡产品采用由可持续材料聚酰胺制成的镜片,经证实使用了生物基材料并减少了排放。
蔡司太阳镜片采用质量平衡法处理生物基材料,即在同一生产过程中处理生物基材料和标准化石基材料,而不是分开处理。
质量平衡过程即在同一生产过程中使用生物基材料和标准化石基材料,而非分开在不同的生产厂处理。通过验证及认证系统核算平衡生物基材料的使用量。
关键数字
应用于整个价值链的质量平衡法
从原材料变成成品镜片,需经过许多生产步骤,使用许多资源。现在,整个生产链都通过了 REDcert2 标准认证,生产真正可持续发展的聚酰胺镜片。REDcert2 标准是欧洲少数的可持续发展认证体系之一,可对所有阶段进行验证。
REDcert² 采用质量平衡法:这种核算方法确保可持续生物基原料在上游设备中与化石基原料混合。然后,按照价值链每一步核实数量的原则,把它们专门分配给下游平光太阳镜片的生产。
