Chinese investment in steel assets needs to be aligned with a Paris-compatible scenario to avoid locking in emissions and stranded assets, according to a report by non-profit Climate Bonds Initiative (CBI).
Almost 80pc or 730.8mn t/yr of China's existing coal-based blast furnace capacity will need to be retired or require reinvestment by 2030, CBI said in its report released last week. Steel asset lifetimes often exceed 40 years, so "investment decisions made today can lock in billions of tons of emissions and potentially billions of dollars in stranded assets", CBI added.
Steel production currently accounts for around 8pc of global CO2 emissions, and almost 50pc of global steel output is from China, CBI said. China's steel sector is estimated to require at least 1.6 trillion yuan ($226bn) in fixed asset investment for decarbonisation by 2050, according to a joint report by CBI and US-based Rocky Mountain Institute (RMI) earlier this year. Of the Yn1.6 trillion, 33pc should go to energy efficiency, 23pc for electric arc furnaces, 18pc for direct iron reduction (DRI), 14pc for carbon capture, utilisation and storage (CCUS), 7pc for blast furnace hydrogen injection, and 5pc for pellet manufacturing.
Green bonds
Steel companies can obtain financing through labelled green bonds from various categories at the project level, including energy efficiency, heat recycling, waste and resource recycle, green hydrogen, biomass, and CCUS.
A total of Yn4.46 trillion of labelled green bonds had originated from China in domestic and overseas markets as of the end of 2023, according to CBI. But Chinese steel firms had only issued 23 green bonds totalling Yn3.5bn and six sustainability-linked bonds totalling Yn1.6bn by the end of last year, representing 0.1pc of the total Chinese labelled bond market. This Yn5.1bn falls very short of the estimated Yn1.6 trillion needed to decarbonise the Chinese steel sector.
CBI asserts that the labelled bond and loan market can supply the required capital, but issuers operating in the steel sector must be encouraged to price deals with the recommended transparency and credibility.
Recommendations
Several Chinese provinces have already issued provincial-level transition finance guidance, including major steel-producing Hebei province this year. But China's national-level transition finance guidance remains under development.
CBI thus recommends that the national transition taxonomy further align provincial guidelines and "enhance interoperability" between Chinese and international transition taxonomies, incentivise low-carbon production methods, customise financing for small-to-medium companies, and enhance entity-level transition plans.
CBI also suggests that banks incentivise companies to enhance the quality of their information disclosure and integrate such incentives into their transition frameworks. The non-profit also urged steel companies to issue credible transition plans, which should include Paris-aligned emission-reduction targets and clear capital expenditure plans.
Lastly, CBI notes that policies should support hydrogen infrastructure and supply chain development to accelerate green hydrogen deployment for high-emitting sectors. This is especially as current financing to decarbonise heavy industrial sectors have mainly been for mature technologies, such as raising energy efficiency. But green hydrogen can reduce over 90pc of steel production emissions, and steady development in hydrogen infrastructure and supply chain will cut costs and accelerate the steel transition.
CBI also flagged public sector steel procurement as an avenue through which the country can boost demand for green steel, especially since Chinese public authorities buy about 350mn t/yr of steel, which causes around 689mn t/yr of CO2 emissions. Green public procurement (GPP) policies in China would also have a global impact, with steel public procurement demand in China three times that of India's total steel demand of 100mn t/yr. CDI suggests that the Chinese government accelerate adopting national-level standards to ensure consistent embodied emissions reporting, as GPP policies will only be effective when implemented with standardised methodologies.
