- Global Carbon dioxide ( CO2) emissions hit a record high in 2023, driven by increased fossil fuel use.
- Scientists urgently need steep cuts in CO2 emissions to meet climate goals.
The International Energy Agency (IEA) reported that global carbon dioxide (CO2) emissions from energy use hit a record high last year. This is partly due to increased fossil fuel use in regions affected by droughts.
Scientists stress the urgent need for steep cuts in CO2 emissions, primarily from burning fossil fuel. In order to meet global temperature rise targets and prevent runaway climate change.
The IEA states in its latest report that CO2 emissions reached a new record high. This is contrary to the necessary rapid decline prescribed by the Paris Agreement.
The IEA analysis shows a 1.1 per cent increase in global energy-related emissions, totalling 37.4 billion tonnes in 2023. Advancements in clean technologies like wind, solar, and electric vehicles helped curb emissions growth, compared to the 1.3 per cent rise in 2022.
However, factors such as China’s economic recovery increased fossil fuel use in regions. With low hydropower output, a rebound in the aviation sector led to an overall rise.
According to the IEA, compensating for the shortfall in hydropower output due to severe droughts accounted for around 40 per cent of the emissions surge. The United States saw a 4.1 per cent decline in emissions, primarily from the electricity sector.
In comparison, the European Union experienced nearly a 9 per cent decrease. This is driven by renewable energy growth and reduced coal and gas power.
China witnessed a 5.2 per cent rise in energy-related emissions, driven by post-COVID-19 recovery efforts. But it also contributed significantly to global renewable energy adoption, including solar, wind, and electric vehicles, which surged by 60 per cent in 2023. Reaching 14 million units and accounting for one-fifth of new car sales worldwide.
