Global coal consumption is set to rise to an all-time high in 2022 and remain at similar levels in the next few years if stronger efforts are not made to move toward a low-carbon economy, said a report by the International Energy Agency (IEA) on Friday.

High gas prices, following Russia's invasion of Ukraine and consequent disruptions to supply, have led some countries to turn to relatively cheaper coal this year.

Heat waves and droughts in some regions have also driven up electricity demand and reduced hydropower, while nuclear generation has also been weak, especially in Europe, where France had to shut down nuclear reactors for maintenance.

The IEA's annual report on coal forecasts global coal use is set to rise by 1.2% this year, exceeding 8 billion tons in a single year for the first time, bypassing a previous record set in 2013.

It also predicts that coal consumption will remain flat at that level till 2025 as falls in mature markets are offset by continued strong demand in emerging Asian economies.

This means coal will continue to be the global energy system’s largest single source of carbon dioxide emissions by far.

The largest increase in coal demand is expected to be in India at 7%, followed by the European Union at 6%, and China at 0.4%.

"The world is close to a peak in fossil fuel use, with coal set to be the first to decline, but we are not there yet," said Keisuke Sadamori, the IEA’s director of energy markets and security.

Europe's coal demand has risen due to the rapid switch from gas to coal owing to high gas prices and with Russian gas supplies trickling.

However, by 2025 European coal demand is expected to decline below 2022 levels, the report added.

Global coal-fired power generation is set to rise to a new record of around 10.3 terawatt-hours this year, while coal production is forecast to rise by 5.4% to around 8.3 billion tons, also an all-time high.

Production is expected to reach a peak next year but should fall below 2022 levels by 2025.

The three largest coal producers – China, India and Indonesia – will all hit production records this year, but despite high prices and comfortable margins for coal producers, there is no sign of an investment surge related to export-driven coal projects.

This reflects caution among investors and mining companies about the medium and long-term prospects for coal, the report cautioned.
