Global carbon dioxide (CO2) emissions are on track to increase by approximately 1% in 2023, according to climate scientists. This projection, unveiled in preliminary research, highlights the formidable challenge of reducing emissions at the necessary pace to align with the Paris Agreement’s goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels. The final analysis, due in December, will offer a comprehensive view of CO2 emissions from all sources. Despite hopes that emissions might have peaked in previous years, they continue to rise, underscoring the urgent need to transition away from fossil fuels and expand clean energy sources. The persistent rise in emissions presents a significant obstacle to international efforts to combat climate change.
