Overview
What it means
Published in 2020 and developed with sector stakeholders, L. 1470 translates climate science into sector-level emission pathways for ICT goods, networks and services — giving operators, manufacturers and service providers a common reference for science-based target setting alongside ITU's L. 14xx environmental methodology family.
How it is used
ICT companies use L. 1470 trajectories when setting and validating emission targets; industry initiatives and the Science Based Targets initiative's ICT guidance reference it. It also frames sector reporting on alignment with Paris goals.
Why it matters
Without a sector trajectory, every ICT company defines its own 'aligned with 1. 5°C'. L. 1470 supplies the shared benchmark — and thereby the test — for the sector that AI infrastructure belongs to.
