The political economy of net-zero transitions: Policy drivers, barriers, and justice benefits to decarbonization in eight carbon-neutral countries

Abstract

This study examines the political economy of decarbonization in eight countries over the period 2000 to 2021/2022 that have already achieved a national net-zero transition. These countries are Bhutan, Suriname, Panama, Guyana, Comoros, Gabon, Madagascar, and Niue. It utilizes an analytical method of a rich, interdisciplinary and systematized literature review integrated with thematic analysis. For each of these countries, the study examines the drivers and political motivation behind net-zero progress, including the timeline of events; the barriers and challenges that had to be overcome; and the benefits of decarbonization and its impacts on equity and justice. The main objectives of the study are to broaden the evidence base on low-carbon transitions beyond often and even overstudied countries that are Western, Educated, Industrialized, Rich, Democracies, or WEIRD countries, and to offer new empirical data on the strategy of energy policies in the real world, examining the first eight countries to achieve net-zero success in the modern era. It finds that all eight countries used a similar mix of nine policy interventions involving land use, renewable energy, and waste management. Common barriers included vulnerability to the effects of extreme climate events either in the form of natural disasters (i.e. landslides and floodings) or ecosystems degradation (i.e. ocean acidification, coastal erosion and forests loss). Despite these barriers, achieving net-zero emissions positively impacted marginalized communities by providing a more equitable distribution of climate benefits, mitigating adverse health effects and reducing social inequalities, particularly in low-income areas.
