电子技术的进步有潜力提高能源效率和减缓气候变化，但也可能由于整个产品生命周期中资源和能源的使用而产生气候影响。这些权衡围绕着电子产品的设计、制造、购买、使用和处置方式以及将这些系统转向资源效率的能力。消费电子产品的一个有前途的战略是促进采用轻质、节能、多功能设备作为目前拥有的许多单一功能电子产品的替代品。然而，消费者的偏好和做出这种转变的意愿仍不清楚。一项针对美国 1,011 名成年人的调查显示了理论上材料效率提升的潜力，因为受访者表示愿意接受较少数量的多功能设备（例如智能手机）作为专业电子产品（包括数码相机、摄像机和 MP3 播放器）的替代品。然而，当实际选择用于常见功能（例如看电视、获取路线、上网或写电子邮件）的电子产品时，消费者表现出对这些任务中感知质量最高的产品的强烈偏好。据报道，平板电脑等多功能设备仅用于其可提供的少数功能，并且通常是现有产品的冗余补充，而不是替代品。研究结果表明，仅通过设备融合来降低材料强度是有限的。该行业的非物质化可能需要共同努力设计多功能产品以提高性能，同时还要改善消费者不愿更换的产品的材料和气候足迹。本文满足 http://jie.click/badges 中描述的金级 JIE 数据开放徽章的要求。
Advances in electronic technologies have the potential to enable energy efficiency and climate mitigation but may also create climate impacts due to resource and energy use across the product life cycle. These tradeoffs revolve around the way electronics are designed, manufactured, purchased, used, and disposed and the ability to shift these systems toward resource efficiency. A promising strategy for consumer electronics is to facilitate adoption of lightweight, energy‐efficient, multi‐functional devices as replacements for the many single‐function electronic products currently owned. However, consumer preferences and willingness to make this shift remain unclear. Here, a survey of 1,011 adults across the United States demonstrated theoretical potential for material efficiency gains, as respondents indicated willingness to accept a smaller number of multi‐functional devices, such as smartphones, as replacements for specialized electronics, including digital cameras, camcorders, and MP3 players. However, when actually choosing electronics to be used for common functions, such as watching TV, getting directions, surfing the Internet, or writing an email, consumers indicated strong preferences for products with the highest perceived quality for those tasks. Multi‐functional devices such as tablets were only reported to be used for a small number of the functions they can provide and were typically redundant complements to existing products, rather than substitutes. Findings suggest a limit to material intensity reductions via device convergence alone. Dematerialization of this sector will likely require coupled efforts to design multi‐functional products for improved performance while also improving the material and climate footprint of products that consumers are unwilling to replace.
