JAKARTA — Indonesia’s steel industry is becoming one of the country’s fastest-growing sources of greenhouse gas emissions, even as it receives far less public attention than other carbon-intensive sectors. The industry is already one of the country’s largest industrial emitters, and is set to become far more polluting if current trends continue, according to a report by environmental NGO Action for Ecology and People’s Emancipation (AEER). Global demand for steel is rising, driven by the expansion of electric vehicles, renewable energy and infrastructure projects. Against this backdrop, Indonesia’s crude steel production climbed to around 16.8 million metric tons, making it the world’s 15th-largest steel producer in 2023, according to the World Steel Association. AEER estimates that Indonesia’s steel output could grow twelvefold by 2060, with emissions rising 11.7 times from 2023 level if the industry continues to rely on coal-based production. At that scale, steel alone could account for around 31% of Indonesia’s national greenhouse gas emissions by 2060 if current policies remain unchanged, potentially putting Indonesia’s net-zero target out of reach. Indonesia’s high emissions stem largely from its reliance on coal-based blast furnace steelmaking, which uses coal both as a chemical input and as a source of the extremely high heat required to smelt iron ore. “The steel industry is one of the largest emitters within the industrial sector, making it a top priority for decarbonization. Steelmaking processes require extremely high temperatures, resulting in very high emissions,” said Timotius Rafael, a researcher at AEER, as quoted by local news.…This article was originally published on Mongabay
