On 15 October 2019, Jonas Teusch (OECD Centre for Tax Policy and Administration) discussed the key findings from the OECD publication, Taxing Energy Use 2019, which presents new and original data on energy and carbon taxes in OECD and G20 countries, and in international aviation and maritime transport. Global energy consumption rose strongly in 2018 along with energy-related CO2 emissions, reaching a new all-time high. This is disconcerting, as meeting the goals of the Paris Agreement will require deep cuts in emissions. Taxing polluting sources of energy is an effective way to curb emissions that harm the planet and human health. Where do countries stand in deploying energy and carbon taxes to reach environmental and climate goals? How can governments step up efforts?
