BAKU, Azerbaijan, March 2. Emissions from oil grew by 2.5% (or 268 Mt) to 11.2 Gt in 2022, Trend reports via the International Energy Agency (IEA).
"Around half of the year-on-year increase came from aviation as air travel continued its recovery from pandemic lows. The rebound to pre-pandemic emissions levels was faster in advanced economies, where last year’s aviation emissions reached 85% of 2019 levels, compared with 73% in emerging market and developing economies. Total transport emissions increased by 2.1% (or 137 Mt), also driven by growth in advanced economies," reads the report.
Nonetheless, the report reveals that emissions would have been higher without the accelerating deployment of low-carbon vehicles. Electric car sales surpassed 10 million in 2022, making up over 14% of global sales. If all new electric cars on the road had been typical diesel or gasoline cars, global emissions last year would have been another 13 Mt higher.
Global carbon dioxide (CO2) emissions from energy combustion and industrial processes1 grew 0.9% or 321 Mt in 2022 to a new all-time high of 36.8 Gt. This estimate is based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, incorporating the latest official national statistics and publicly available data on energy use, economic indicators, and weather. Last year’s increase follows two years of exceptional oscillations in energy-related emissions. Emissions shrank by more than 5% in 2020, as the Covid-19 pandemic cut energy demand. In 2021, emissions rebounded past pre-pandemic levels, growing more than 6% in tandem with economic stimulus and the roll-out of vaccines.
