LONDON - Global fossil fuel consumption and energy emissions hit all-time highs in 2023, even as fossil fuels' share of the global energy mix decreased slightly on the year, the industry's Statistical Review of World Energy report said on Thursday.

Growing demand for fossil fuel despite the scaling up of renewables could be a sticking point for the transition to lower carbon energy as global temperature increases reach 1.5C, the threshold beyond which scientists say impacts such as temperature rise, drought and flooding will become more extreme.

"We hope that this report will help governments, world leaders and analysts move forward, clear-eyed about the challenge that lies ahead," Romain Debarre of consultancy Kearney said.

China accounted for over half of global additions in renewable energy generation last year

Overall global primary energy consumption hit an all-time high of 620 Exajoules (EJ), the report said, as emissions exceeded 40 gigatonnes of CO2 for the first time.

"In a year where we have seen the contribution of renewables reaching a new record high, ever increasing global energy demand means the share coming from fossil fuels has remained virtually unchanged," Simon Virley of consultancy KPMG said.

The report recorded shifting trends in fossil fuel use in different regions. In Europe, for example, the fossil fuel share of energy fell below 70 percent for the first time since the industrial revolution.

"In advanced economies, we observe signs of demand for fossil fuels peaking, contrasting with economies in the Global South for whom economic development and improvements in quality of life continue to drive fossil growth," Energy Institute Chief Executive Nick Wayth said.

Industry body the Energy Institute, together with consultancies KPMG and Kearney, has published the annual report since 2023. They took over from BP last year, which had authored the report, a benchmark for energy professionals, since the 1950s.

Fossil fuel accounted for almost all demand growth in India in 2023, the report said.

China accounted for over half of global additions in renewable energy generation last year.

“China adding more renewables than the rest of the world put together is remarkable," KPMG's Virley told reporters.
