Fossil fuel subsidy reform is the missing piece of the climate change puzzle. It’s estimated that more than a third of global carbon emissions, between 1980 and 2010, were driven by fossil fuel subsidies. Their elimination would represent one seventh of the effort needed to achieve our target of ensuring global temperatures do not rise by more than 2°C. As with any subsidy reform, change will take courage and strong political will, but with oil prices at record lows and the global focus on a low-carbon future – the timing for this reform has never been better.
