论文摘要
鉴于最近的算法,软件和硬件创新,计算使许多新应用程序都能实现。但是,随着计算越来越普遍,其环境影响也会产生影响。本文将该问题引起了计算机系统研究人员的注意。我们的分析建立在行业报告的特征上,量化了计算在碳排放方面的环境影响。从广义上讲,碳排放有两个来源:运营能源消耗以及硬件制造和基础设施。尽管由于算法,软件和硬件创新促进了性能和功率效率,但前者的碳排放量正在减少,但计算机系统的整体碳足迹仍在不断增长。这项工作量化了计算机系统的碳输出,以表明与现代移动和数据中心设备相关的大多数排放都来自硬件制造和基础设施。因此,我们概述了将来的指示,以最大程度地减少计算系统的环境影响。
Given recent algorithm, software, and hardware innovation, computing has enabled a plethora of new applications. As computing becomes increasingly ubiquitous, however, so does its environmental impact. This paper brings the issue to the attention of computer-systems researchers. Our analysis, built on industry-reported characterization, quantifies the environmental effects of computing in terms of carbon emissions. Broadly, carbon emissions have two sources: operational energy consumption, and hardware manufacturing and infrastructure. Although carbon emissions from the former are decreasing thanks to algorithmic, software, and hardware innovations that boost performance and power efficiency, the overall carbon footprint of computer systems continues to grow. This work quantifies the carbon output of computer systems to show that most emissions related to modern mobile and data-center equipment come from hardware manufacturing and infrastructure. We therefore outline future directions for minimizing the environmental impact of computing systems.
