As we move steadily into a world affected by climate change and environmental degradation (CC&ED), and the need for adaptation to its increasingly serious and disruptive effects (IPCC, 2022a), there is growing recognition that young children will be the most profoundly affected (Thiery et al., 2021) but they are at the same time the least well represented in the policies and programs designed to respond to current impacts and plan for future consequences (ARNEC, 2022; CCC, 2015; Pegram & Colon, 2020). This Scoping Study, written by the Early Start, University of Wollongong in Australia, is a response by ARNEC and its partners UNCEF EAPRO and Save the Children International to this situation, designed to put early childhood development (ECD) at the heart of climate actions. This document is an abridged version of the three main components taken from the scoping study. The full study will be released no later than 30 November 2022 and will be made available in the ARNEC website: https://arnec.net/
