Fossil fuel subsidies are killing both people and the planet. By encouraging excessive consumption of fossil fuels, subsidies exacerbate pollution and climate change, make violent protests more likely, and waste huge sums that could be used far better. Yet for years there has been minimal progress in eliminating fossil fuel subsidies. This book explains what fossil fuel subsidies are, how they inflict harm and what steps are being taken to reduce them. It also shows why subsidies persist and why existing efforts have been so ineffective. Drawing lessons from countries which have tried to remove fossil fuel subsidies, it explains that the fundamental challenge to reform is not technical, but political. The catastrophic COVID-19 pandemic and the tragic war in Ukraine illustrate that fossil fuel subsidy reform will only succeed where it supports the achievement of things that really matter politically - energy security, protection from climate change, better air quality, and resources to improve people’s lives. The book lays out a new agenda for action on fossil fuel subsidies, showing how a better understanding of the underlying political incentives can lead to more effective approaches to tackling this major global problem.
