Global Energy & CO2 Status Report
The IEA’s first Global Energy and CO2 Status Report – released in March 2018 – provides a snapshot of recent global trends and developments across fuels, renewable sources, and energy efficiency and carbon emissions, in 2017.
Carbon Dioxid (CO2)
Global energy-related CO2 emissions grew by 1.4% in 2017, reaching a historic high of 32.5 gigatonnes (Gt), a resumption of growth after three years of global emissions remaining flat.
The biggest decline came from the United States, mainly because of higher deployment of renewables, followed by the United Kingdom, Mexico and Japan.
World oil demand rose by 1.6% (or 1.5 million barrels a day) in 2017, a rate that was more than twice the annual average seen over the last decade.
Global natural gas demand grew by 3%, thanks in large part to abundant and relatively low-cost supplies. China alone accounted for almost 30% of global growth. In the past decade, half of global gas demand growth came from the power sector; last year, however, over 80% of the rise came from industry and buildings.
Global coal demand rose about 1% in 2017, reversing the declining trend seen over the last two years. This growth was mainly due to demand in Asia, almost entirely driven by an increase in coal-fired electricity generation.
Renewables saw the highest growth rate of any energy source in 2017, meeting a quarter of global energy demand growth. Wind power accounted for 36% of the growth in renewables-based power output.
World electricity demand increased by 3.1%, significantly higher than the overall increase in energy demand. Together, China and India accounted for 70% of this growth. Output from nuclear plants rose by 26 terrawatt hours (TWh) in 2017, as a significant amount of new nuclear capacity saw its first full year of operation.
Improvements in global energy efficiency slowed down dramatically in 2017, because of weaker improvement in efficiency policy coverage and stringency as well as lower energy prices.
