The United Kingdom is considering major reforms to its upcoming carbon border scheme. The mechanism, due to begin in January 2027, charges carbon costs on imported steel. The government wants to align its rules more closely with the stricter European Union model. Officials fear the current design, using a single global average emissions value, could attract the world's dirtiest steel. Reforms under study include country-specific values & product-specific benchmarks. Talks to link the United Kingdom & European Union carbon trading systems have reportedly concluded ahead of a November summit. The coming months will prove decisive.
