729. Global Greenhouse Gas Emissions in 2022

Today's article provides an update on the topic of greenhouse gas emissions in the energy sector.

On March 2, the International Energy Agency (IEA) released its  energy-related report CO2 Emissions in 2022.

Global CO2 emissions increased 0.9% from the previous year to an all-time high of 36.8 billion tons. However, the growth rate from the previous year was less than initially feared, as the impact of greater coal and oil use under the global energy crisis was offset by growth in the clean energy sector, including solar and wind power generation and improved energy use efficiency.

Compared to 2021, when greenhouse gas emissions grew 6% year over year, the growth rate in 2022 was 0.9%, which is moderate compared to the 3.2% global economic growth rate, suggesting a return to emission reductions once interrupted by the rapid emission growth due to the rebound in economic activity after the COVID crisis. In fact, the global energy crisis has been a major factor in the global economic crisis and has led to increase in coal emissions as Asia and Europe switched from gas to coal, but the 1.6% decrease in natural gas emissions offset the increase in coal emissions, due in part to conservation efforts by European companies and citizens in the face of natural gas supply constraints following the Russian invasion of Ukraine. Emissions from oil rose 2.5%, half of which came from the aviation sector, which is recovering after the pandemic. Although emissions were partially offset by the increased application of clean energy technologies, the report found that greenhouse gas emissions are trending unsustainably over the long term and called for a further acceleration of the clean energy transition.
