Despite a growing consensus in favour of reform of costly and environmentally damaging energy price subsidies, many countries remain resistant. This column takes stock of recent developments using an updated energy price database. Environmental concerns seem to be playing a larger role in driving reform, but most reforming countries are found to have been facing large fiscal imbalances. These countries may need additional, deeper measures for the reforms to last.

Most policies that target climate change – such as carbon taxes and cap-and-trade programmes – have long-term benefits but short-term economic costs. This column argues that population policies may not be subject to this trade-off. In particular, policies that reduce population growth can have a direct positive effect on income per capita as well as lowering growth of carbon emissions. Such policies could play an important role in the portfolio of actions aimed at mitigating climate change.
