Well-Below 2°C Pathway

Meaning statusEstablishedSource recordDirect document linkedWhy these are different

Definition

A well-below 2°C pathway is a modelled emissions and decarbonisation trajectory aligned with the Paris Agreement goal of holding the increase in global average temperature to well below 2°C while pursuing efforts toward 1.5°C. Scenario sets such as the IEA Sustainable Development Scenario and Science Based Targets initiative sector pathways operationalise the benchmark.

Overview

How it is used

SBTi historically validated targets against well-below 2°C and 1. 5°C pathways; investors assess portfolio alignment using pathway benchmarks; regulators and disclosure frameworks reference Paris-aligned pathways in transition-plan guidance.

Why it matters

It converts the Paris temperature goal into a measurable yardstick, giving target-setting and climate claims a common scientific reference point.
