The fossil fuel industry is heavily subsidised
Subsidies are intended to protect consumers by keeping prices low, but they come with significant costs and negative consequences. They have fiscal implications, leading to higher taxes, more borrowing, or reduced spending. They also promote inefficient allocation of resources, hindering economic growth, and encourage pollution, contributing to climate change and adverse health effects. The largest contributors to global fossil fuel subsidies are underpricing for local air pollution costs and climate change damages, accounting for about 30% each. Explicit subsidies, broader road transport externalities, and forgone consumption tax revenue also make up a significant portion.
While some countries have successfully phased out explicit subsidies and introduced taxes, many countries have struggled to reform subsidies despite the potential gains. The United States, for example, provides numerous tax subsidies to the fossil fuel industry, including direct subsidies to corporations and other tax benefits. Conservative estimates put US direct subsidies at $20 billion per year, with 20% allocated to coal and 80% to natural gas and crude oil.
Removing fossil fuel subsidies would reduce energy security concerns related to volatile fossil fuel supplies and encourage a transition to clean energy sources. It would also increase government revenues and put emissions on track to meet global warming targets. However, removing subsidies can be challenging, and governments must carefully design and communicate reforms to ensure a smooth transition.
