Figure 3 shows a comparison of the IEA and WSD views and the related iron ore demand of between 400 and 600 mt by 2050, compared to about 160 mt in 2019. From the quantitative perspective, iron ore supply should not be an issue, with BF iron production falling from just under 1.3 billion tonnes in 2019 to 665 mt by 2050 per IEA's SDS (see Figure 1).
