Thankfully it’s an important enough question that some people have already done some work for us. The IMF put out a report last year about this very subject. Here’s a relevant snippet from the summary: > Globally, fossil fuel subsidies were $5.9 trillion in 2020 or about 6.8 percent of GDP, and are expected to rise to 7.4 percent of GDP in 2025. Just 8 percent of the 2020 subsidy reflects undercharging for supply costs (explicit subsidies) and 92 percent for undercharging for environmental costs and foregone consumption taxes (implicit subsidies).
