Global carbon pollution hits record high

Steep cuts in carbon emissions, mainly from burning fossil fuels, will be needed in the coming years if targets to limit a global rise in temperatures and prevent runaway climate change are to be met, scientists have said.

Global emissions from energy rose by 410 million metric tons, or 1.1 percent, in 2023 to 37.4 billion metric tons, the IEA analysis showed.

A global expansion in clean technology such as wind, solar and electric vehicles, helped to reduce the rate of emissions growth, which was 1.3 percent in 2022. But a reopening of China’s economy, increased fossil fuel use in countries with low hydropower output and a recovery in the aviation sector led to an overall rise, the IEA said in its report.

Moves to replace lost hydropower generation due to extreme droughts accounted for around 40 percent of the emissions rise, or 170 million tonnes of CO2.

Energy-related emissions in the United States fell by 4.1 percent, with the bulk of the reduction coming from the electricity sector, according to the report.

In the European Union, emissions from energy fell by almost 9 percent last year, driven by a surge in renewable power generation and a slump in both coal and gas power generation.

In China, emissions from energy rose by 5.2 percent, with energy demand growing as the country recovered from Covid-19-related lockdowns, the report said. China, however, also contributed around 60 percent of global additions of solar, wind power and electric vehicles in 2023, the IEA said.
