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

In Sustainability

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...
