The politics of climate policy innovation: the case of the Argentine carbon tax

"This contribution analyzes the policymaking process of the carbon tax in Argentina based on the multiple streams approach (MSA). The study shows how policy entrepreneurs took advantage of a general tax reform bill to promote the idea of a carbon tax. Mainly driven by international emulation and reputational gains concerns, the carbon tax proposal successfully advanced through the government´s internal drafting process of the Tax Reform Bill, however, it faced strong opposition during the legislative decision-making process, which resulted in the adoption of a weaker carbon tax. From a climate politics perspective, the Argentine carbon tax case suggests the political limitations of an overreliance on international reputation arguments to advance climate policy innovation. In relation to the MSA, the study highlights how policy windows can shape processes of policy innovation and the analytical convenience of differentiating the coupling processes between the agenda-setting and decision-making stages."
