A multi-model assessment of inequality and climate change

J. Emmerling, P. Andreoni, et al.

This groundbreaking research explores the interplay between climate change and inequality, utilizing a set of eight advanced integrated assessment models. The findings reveal that while climate impacts could exacerbate inequality by 2100, limiting temperature rise to below 1.5°C offers a means of mitigating this increase. Remarkably, equal per-capita redistribution can counteract the adverse effects of climate policy on inequality. Authored by a team of experts including Johannes Emmerling and others, the study advocates for well-structured policies that can both stabilize the climate and foster economic inclusivity.

Abstract

Climate change and inequality are critical and interrelated issues. This paper uses an ensemble of eight large-scale integrated assessment models to quantify the distributional implications of climate impacts and climate policies compatible with the Paris Agreement. By 2100, climate impacts will increase inequality, but maintaining temperatures below 1.5°C reduces this increase. Equal per-capita redistribution can offset short-term inequality increases from climate policies. The study finds that well-designed policies can stabilize the climate and promote economic inclusion.
