Industrial Decarbonization in Japan

Japan's industrial sector, which accounts for 36% of the country's GHG emissions, faces significant challenges in achieving carbon neutrality by 2050. The steel and chemical sectors are the primary emitters, both relying heavily on fossil fuels (80-90% of energy consumption) and currently lacking the necessary technology, infrastructure, and capital to transition. While demand for green products is relatively ready due to low impact on end consumers, the report emphasizes the need for massive investments in clean hydrogen and CCUS, as well as the strategic use of industrial clusters (kombinat) to accelerate decarbonization through cross-sectoral collaboration.

• Industries are a major contributor to Japan's climate impact, accounting for 36% of the nation's greenhouse gas (GHG) emissions and 42% of its final energy consumption.
• The steel and chemical sectors are the most critical for industrial decarbonization, together representing nearly half of Japan's industrial emissions, with steel alone accounting for 32% and chemicals 14%.
• Japan's steel industry is highly dependent on the blast furnace (BF) route, which is more emissions-intensive than electric arc furnace (EAF) or direct reduced iron (DRI) routes, and it requires an estimated $77 billion (JPY 10 trillion) to transform its asset base by 2050.
• The chemical industry in Japan relies exclusively on naphtha steam cracking for high-value chemical (HVC) production and requires between $57 billion and $75 billion (JPY 7.4–9.7 trillion) to transform its asset base by 2050.
• Both the steel and chemical sectors exhibit low readiness in technology, infrastructure, policies, and capital, although demand readiness is higher because green premiums have a minimal impact on end consumers.
• Japan's direct carbon price is among the lowest in advanced economies at $2 (JPY 249)/tCO2, though indirect carbon prices bring the effective rate to approximately $28 (JPY 3,659)/tCO2.
• Industrial complexes, known as kombinat, are central to Japan's strategy, with nine major complexes emitting a combined 126 Mt of CO2 annually.
• Hydrogen is identified as the most critical enabling technology for decarbonizing Japan's industrial complexes, followed by CCUS, systemic efficiency, and circularity.
