Energy plays a critical role in the functioning of modern economies. At the same time, it’s at the heart of many of today’s pressing environmental concerns—from global warming (predicted to reach around 3–4 degrees Celsius by the end of the century) and outdoor air pollution (causing over three million premature deaths a year) to traffic gridlock in urban centers. In a new IMF book, we look at precisely how policymakers can strike the right balance between the substantial economic benefits of energy use and its harmful environmental side effects.
These environmental impacts have macroeconomic implications, and with its expertise in tax design and administration, the IMF can offer sound advice on how energy tax systems can be designed to ensure energy prices fully reflect adverse environmental impacts.
We do this by developing a sensible and reasonably simple way to quantify environmental damages and applying it, in over 150 countries, to show what these environmental damages are likely to imply for efficient taxes on coal, natural gas, gasoline, and road diesel. For example, the human health damages from air pollution are calculated by estimating how many people are exposed to power plant and vehicle emissions in different countries and how this exposure increases the risk of various (e.g., heart and lung) diseases. Although there are some inescapable controversies in this approach (e.g., concerning the valuation of global warming damages or how people in different countries value health risks), the methodology is flexible enough to easily accommodate alternative viewpoints—it is a starting point for debate, not a final point of arrival.
