Annual change in power sector emissions worldwide 2001-2023

Global power sector emissions increased by 1.25 percent in 2023, relative to 2022 levels. Annual global power sector emissions have only reduced four times since 2001, with the largest reduction occurring in 2020, at 3.05 percent. Emissions rebounded almost seven percent the following year as global economies began to recover from the outbreak of COVID-19. A similar scenario occurred in 2009, when the global financial crisis caused emissions to fall 1.5 percent, before rebounding almost seven percent the following year.
