2022 Was Another Record Year for CO2 Emissions, Says New Report

Mar 03 2023

Despite concerns over the pandemic, global CO2 emissions have continued to rise at an alarming rate, reaching new record levels in 2022, according to a report by the International Energy Agency (IEA). The report reveals that global CO2 emissions related to energy production grew by 0.9%, reaching over 36.8 billion metric tons. While this growth was slower than expected, it is still a significant cause for concern, particularly as global emissions must be significantly reduced to meet climate targets. 

The report highlights the impact of renewable energy growth, which offset some of the increased use of coal, oil, and natural gas. However, experts warn that global CO2 emissions must shrink sustainably to achieve the necessary climate targets. The IEA notes that "emissions still remain on an unsustainable growth trajectory." 

The report highlights several factors that have contributed to the increased CO2 emissions, including the war in Ukraine, disruptions in Russian exports of oil and natural gas, pandemic-related work restrictions in China, international energy price shocks, rising inflation, and disruptions in trade flows. Despite these disruptions, the IEA warns that the increase was not as slow as they had hoped. 

The report states that the carbon dioxide growth rate was much slower than 2021's growth rate of over 6%. Still, it is important to note that last year brought its own litany of disruptions, such as industrial production curtailments in China and Europe, a plunge in natural gas consumption in Europe by 13.5%, and renewables meeting 90% of global growth in electricity generation. 

According to Antoine Halff, a founding partner of energy consulting firm Kayrros, "China's zero-covid policy and the war in Ukraine took a big bite off of world carbon emissions last year, but that was partly offset by a resurgence of coal as a substitute for scarce or pricey natural gas." 

Furthermore, the report reveals that of the 321 million metric ton increase in carbon dioxide emissions, just over half could be attributed to extreme weather events and heating demands, while the rest was due to nuclear power plants being offline. 

The United States saw emissions grow by 0.8%, with extreme temperatures leading the building sector into the highest emissions growth. While many other countries reduced their natural gas use, the United States increased its use of the fuel by 89 million metric tons. 

Overall, while the growth rate in CO2 emissions was slower than last year's rate, it still highlights the need for urgent and sustained action to reduce carbon emissions. Daniel A. Lashof, the director of the World Resources Institute in the United States, emphasizes that "a smaller increase than 'initially feared' is a far cry from the rapid emission reductions the world needs to see to avoid the worst impacts of global warming." 

The IEA report emphasizes the need for a transition to low-carbon energy sources and the adoption of carbon capture technologies, among other solutions. The report also underscores the critical role of policy in driving emissions reductions, noting that "ambitious policy action is essential to prevent a sustained increase in emissions." 

In conclusion, the IEA report highlights that despite the global disruption caused by the pandemic, carbon emissions have continued to rise, and urgent action is needed to tackle the climate crisis. As Nathaniel Keohane, the president of the Center for Climate and Energy Solutions, notes, "What drives global warming is not carbon intensity. It's total emissions, and those are going up." The report is a timely reminder that reducing carbon emissions must remain a top priority for governments, businesses, and individuals worldwide.
