Reforming fossil fuel subsidies: drivers, barriers and the state of progress

This article outlines the current state of affairs in fossil fuel subsidy reform, and highlights its contribution at the nexus of climate policy, fiscal stability and sustainable development. It discusses common definitions, provides quantitative estimates, and presents the evidence for key arguments in favour of subsidy reform. The main drivers and barriers for reform are also discussed, including the role of (low) oil prices and political economy challenges. Commitments to subsidy reform by the international community are reviewed, as well as the progress at the country level. Although fossil fuel subsidy reform indeed plays a critical role in climate policy, experience shows that the rationale for such reforms is determined in a complex environment of political economy challenges, macro-economic, fiscal and social factors, as well as external drivers such as energy prices. The article synthesizes the key principles for designing effective reforms and emphasizes that subsidy reforms cannot only yield fiscal relief, but should also contribute to long-term sustainable development objectives. Areas for future research are also identified

Investments in material efficiency: the introduction and application of a comprehensive cost–benefit framework

Increasing material efficiency is considered to yield multiple economic and environmental benefits. This paper firstly introduces a comprehensive cost–benefit framework to systematically assess the viability of investments in material efficiency. The framework comprises several components by (1) comparing a business-as-usual scenario with a scenario of scaling up investments in material efficiency, (2) covering economic and environmental dimensions, and (3) considering direct and indirect effects. In a second step, we match the framework to existing evidence from the literature, followed by an application of the framework to a microeconomic investment project financed by a multilateral development bank. Our results suggest that material efficiency investments can yield positive net benefits, which typically increase when non-monetary dimensions are additionally taken into account. Overall, our analysis calls for a more comprehensive approach towards material efficiency investment appraisals, the internalisation of externalities, and further empirical research to better understand the implications of moving towards material efficient economies
