Assessing the Alignment of National Determined Contributions (NDC) and National Adaptation Plan (NAP) with the Outcomes of the First Global Stocktake (GST1) under the Paris Agreement: A Case Study of Timor-Leste

This assessment explored the extent to which Timor-Leste’s nationally determined contribution (NDC) and national adaptation plan (NAP) align with the outcomes of the first global stocktake (GST), using a systematic review based on a structured checklist. The alignment between the NDC and GST outcomes on mitigation was limited, as Timor-Leste’s NDC...

How the Concept of “Regenerative Good Growth” Could Help Increase Public and Policy Engagement and Speed Transitions to Net Zero and Nature Recovery

Sustainability所収

Just and fair transitions to low-carbon and nature-positive ways of living need to occur fast enough to limit and reverse the climate and nature crises, but not so fast that the public is left behind. We propose the concept of “Regenerative Good Growth” (RGG) to replace the language and practice of extractive, bad GDP growth. RGG centres on the...
