The Future of UK Steel?

It's claimed that "If you want to have a car industry, shipbuilding or any form of heavy manufacturing, you need a steel industry". Blast furnaces are essential if you want to make steel from iron ore. They require, however, large work forces as well as producing enormous amounts of climate-altering 'greenhouse gases'. The UK is about to become the only G20 country without a blast furnace for steel production. UK steel production has massively declined, since it was privatised in 1988. The existing UK market has also recently been flooded with cheap, subsidised steel, notably from China. The current owners of steel production in the UK are consequently cutting their blast furnaces. The country is likely to be left only with electric arc furnaces, as they require a much smaller workforce. Electric arc furnaces are less polluting but only produce new steel from scrap (https://www.theguardian.com/business/2024/sep/11/port-talbot-job-losses-whats-next-for-british-steel-production). Jobs losses are a major concern but the reduced workforces would make UK-based steel-producing companies more profitable. The UK has lots of scrap steel. Electric arc furnaces could, consequently, be sufficient for 'local' steel needs. Multinationals might be tempted, of course, to operate blast furnaces in countries with cheaper employment and fewer environmental potections. UK-based electric arc furnaces could use their output to produce specialist steels. Removal of blast furnaces will also help the UK achieve its carbon zero commitments more quickly. The fact that the blast furnaces are abroad, doesn't reduce 'greenhouse gas' emissions. There might, however, be a problem for the UK, if international tensions ever reduce the importation of new steel from overseas blast furnaces.
