引言

本文件基于現(xiàn)有生命周期評價相關(guān)國內(nèi)標(biāo)準(zhǔn)GB/T24040和GB/T24044中確定的原則、要求和

指南，旨在為電解鋁及相關(guān)產(chǎn)品碳足跡量化設(shè)置具體要求。

本文件僅針對單一環(huán)境影響類型，即氣候變化，不評價產(chǎn)品生命周期產(chǎn)生的其他潛在環(huán)境影響，也

不評價產(chǎn)品生命周期內(nèi)可能產(chǎn)生的社會和經(jīng)濟(jì)影響。

本文件提供量化的產(chǎn)品碳足跡信息，使具有同樣功能的電解鋁產(chǎn)品之間可以進(jìn)行比較，一方面可

以為購買方提供可靠和可比的碳足跡信息，另一方面也為生產(chǎn)者持續(xù)改進(jìn)產(chǎn)品的碳足跡績效提供數(shù)據(jù)

支持。提出產(chǎn)品碳足跡聲明的組織宜確保數(shù)據(jù)得到第三方的獨立驗證，以增加報告的準(zhǔn)確性和可

信度。
