T/SPSTS 038—2022

This document standardizes the carbon footprint calculation of portable and light-duty lithium-ion batteries (less than 2 kWh or less than or equal to 25 kg). It includes calculation logic for use, reasonable collection of the carbon footprint of battery materials, division of product carbon footprint levels, calculation of organizational boundary ranges, and display of carbon labels. This document can serve as a reference for other lithium-ion batteries, materials, and recycled materials.
